"Sounds like a great company!"
Reviewed Apr 23, 2019

My husband and I ultimately chose a solar company in our city, but I loved dealing with Energy Sage and getting excellent information about solar from Solar Union. With minimal time and information from me, we had an estimate in only a couple of hours with very detailed plans, price, and an illustration of exactly where the panels would go on our home. Ther was NO high pressure sales pitch, just an offer of helping us with any questions. I appreciated their approach very much and feel they would have been a great company to buy from.

"Very Professional"
Reviewed Feb 17, 2019

I felt like I was dealing with professionals from start to finish. My questions are answered promptly, my concerns are resolved fairly, project was completed ahead of schedule and all aspects of the project was handled in a professional manner. Installation began end of January and by 14th of February I was connected to the grid and saving money. Everything happened smoothly and with very little effort on my part. Not the cheapest of all energy sage recommended installers but like I said all I did was sit back and let them handle everything. If you want the cheapest there are lots of energy sage installers that I'm sure will do a good job. But if you value peace of mind and problem free solar project then I recommend Solar Union.

"Honesty"
Reviewed Jan 09, 2019

"When we decided to go solar, we prepped by researching the companies, talking to our solar friends, and checking the ups and downs of how this would really affect our day to day lives. Of course in the back of my mind I couldn't help but
wonder how much of an inconvenience it would be too get it actually up and running. Since usually when you take on a major home update, it's one problem after another. The first day of our install went amazingly well! The workers were all very friendly and respectful.
My son and I went out a few times to see what they were doing and each time the crew supervisor would come over and explain what was completed and what was next. He even took the time to explain the science behind each step to my son who loves all things science.
Even though we had some extra electrical work done, it didn't slow them down at all. I have never seen such informative, professional, honest and thoughtful crew of workers anywhere! I highly recommend SolarUnion!"

"Low Pressure"
Reviewed Jan 06, 2019

These guys were incredible. The quote was easy, low pressure sales, and since we paid cash the price was below the competition with the best panels out there. I got quotes from 5 companies total, and no one came close to SolarUnion's efficiency and price point. The installers felt like friends after spending a couple of days at our house. The project manager and engineers were great and quick to respond to my emails, and the person who came out to set up the monitoring knowledgeable, patient and down to earth.

"I had a great experience working with SolarUnion. The consultant Karissa was extremely knowledgeable about the panel technology and I could tell she truly believed in it. She was really much less

but I really felt I was in good hands with SolarUnion. I also believe that their performance guarantee was worth the extra investment. Installation was a breeze and I love tracking my production/consumption with the Tigo/SMA app on my phone! The warranty is pretty excellent, so I feel supported should anything ever go wrong. I would absolutely recommend working with this company if you're thinking about going solar."

After getting 4-5 quotes from various companies, we felt very uncomfortable with the process and postponed our decision. We resumed a few months after and went for the company that made itself available to answer our questions and concerns with no pressure. That was SolarUnion. The installation went smoothly.

As an engineer, I'm very detail oriented, and she did not disappoint me. The warranties on power, labor, material, and the roof where a huge selling point as well (we tried to find a company that could match what SolarUnion was offering in protections and warranties, to no avail!).

"Excellent Product and Service. Transparency in the Process”"

We recently acquired a property that had a 9.5 kW PV system installed in 2011 by a company that is no longer in business. We connected with SolarUnion to have the system inspected after 7 years of sitting neglected. The team inspected, repaired, and educated us on the existing system. We understood that based on our needs the existing system was a peak shaver and a latent risk of a true-up bill with the electric company. A month later, we decided to add capacity to the property for additional power needs. SolarUnion handled the excavation for the trench, installation, and coordination with the City and County seamlessly. The price was extremely fair especially against the prices we compared against in the general market and even within the marketplace. We will not hesitate to use SolarUnion for any of our future solar and electrical needs. They took their time and did it right. They set the bar for service, quality, advice, transparency and professionalism. We are very happy with the excellent product, and the excellent service. I could not recommend the Team more highly.”

"Beware - Highest priced quote I received. They are just a marketing company"
Reviewed Oct 02, 2018

Extremely disappointed. High pressure sales team and the prices were the higher than any other solar company including Tesla/Solar City. If one does a bit of reasearch on the company Google maps shows them working out of a barber shop in San Francisco. As another reviewer pointed out they are just a marketing company and sub-contract all of the work out to “real” solar companies. This is proven by looking at the company profile. Company does’t list any engineers, solar designers or contractors only MBAs which worked on multi-million dollar real estate and corporate deals. Not,sure why they gave up their corporate jobs to sell solar out of a barbershop.

One would be well advised to shop around and get quotes from other solar companies including Tesla. When I did I found prices were $11,000 to $16,500 less for same size system using the same brand of solar panels.

I’m just not convinced a bunch of MBAs will be around a few years from now to honor any of their warranties or the performance guarantees they are offering. With a price tag of nearly $50,000 one would be wise to shop around and compare prices and services. Or if you don’t care about price or if the company will be around a few years from now I’m sure at the prices they are charging they will do an okay job.

"Proactive Team"
Reviewed Aug 01, 2018

SolarUnion has done an outstanding job in all aspects of implementing our 16kw PV array. We choose to go the stand-alone route since we have acreage and our roof isn't oriented ideally for maximum efficiency and sun utilization. From the initial site planning (with his neat technology that allows him to pick the best location and orientation), to the design, trenching, footing excavation, support setting, to the final wiring and install, everything was very fast (~ 8-9 days total of on-site labor in my estimation, which is great for a ground mounted system with complex racking solutions). The permitting and inspection process was the most time consuming aspect of this and in SoCal, it takes a while for these things to happen. SolarUnion always had the ball in the Govt. agencies court but it still took several weeks to get things done on the permitting and several more for the inspections. SolarUnion has no control over these aspects and I would give them 6 stars if I could to make up for those reviews that docked him because of the permitting/inspection time.

I have solar in my farm in Germany and I needed to add solar to my home in Marin. Definitely the process is more emotions-driven in California with a lot of noise from so many solar companies and one-man operations. I decided to compare five fairly reputable companies across several factors. It was after weeks of interaction with pushy, untrained and even toxic salespeople that we found out that working with SolarUnion was a breath of fresh air. The combination of quality, superior customer service and overall value made them a clear winner. The consultant approach was also critical in the process. Jim, our assigned advisor, substantiated his claims with hard facts and data. The design team embraced my feedback. The installation crew was professional and did not rush the work on my tile roof. SolarUnion dealt with the County, PG&E and Marin Clean Energy throughout the process. The arrays have been performing better than anticipated and I know because I can monitor instantaneous performance with their Tigo app. Couldn't be happier with the final result.

SolarUnion gave me a high level of confidence that they could deliver. I tend to connect responsiveness to quality of work. The team was responsive to my questions and concerns. My partner also had a long list of questions, all timely and thoroughly addressed. We believe when they say they will be there for us if the system does not deliver.

First off, the outstanding reviews on EnergySage for Solar Union really helped us with selecting them for our work. You just knew they would be a great company to work with. I'm sure the various solar system products out there work great and are trouble-free, so the installation company was more important to us than a particular product. Quote-wise, Solar Union was on par with other companies with similar technologies but might have been a bit lower - just don't remember this detail. Either way, we wanted the best company versus the cheapest quote. Now that our system is complete it's evident we made the right choice. Everyone we worked with at Solar Union was extremely courteous and knowledgeable. Solar Union isn't just trying to install solar systems, they are trying for the highest customer satisfaction possible. And that's us - extremely satisfied we went with Solar Union. Great results are never a surprise when there is a great team involved.

SolarUnion installed a 26 panel system about a year and a half ago, which has been producing 100% of our electricity.

I had earlier received an email from the web-based Tigo monitoring system, but hadn't gotten around to investigate. They asked if they could come out.

One of the optimizers stopped reporting a couple months after installation…they caught it themselves and replaced it…amazing! I had a few issues getting my Tigo monitoring equipment up and running because I changed my internet provider.

"Happy rural customer"
Reviewed Jan 25, 2018

We chose Solar Union because they quoted high-quality components with a 25-year performance guarantee.
Our home is 300+ miles North of San Francisco, a considerable distance from Solar Union's base in the Bay Area. The company assured us that they make installations throughout the state, and representatives from the company indeed traveled up here on separate occasions for roof inspection, installation, and for the county inspection.
We went through several rounds of negotiations of the proposal. We had constructive discussions on how the annual production for our specific area likely would differ from that of the coast, from where more specific data is available, and on the technical and visual impact of various arrangements of the panels on the roof.
The 3-person installation crew arrived early one morning and worked hard and cheerfully through the day into the cold hours of the evening. They also did a meticulous cleanup job.
The Tigo web-based monitoring system came as part of our installation. The performance data is available online with a twenty-minute delay, and it is quite interesting to see the minute-by-minute changes in production when bands of clouds pass over.
From the date of the signing of the contract to the submission of the NEM application to PG&E took four and a half months. The beginning of the rainy season had pushed back the installation schedule, and backlogs in the county building inspections department also caused delays. Importantly, we did meet our goal of completing the installation in the 2017 tax year.

Reviewed Dec 20, 2017

I work in large utility scale solar development so I know a thing or two about solar and I have to say I was impressed by SolarUnion compared to the other companies I received quotes from. While they were not the cheapest quote, I feel like they more than made up for the difference by their level of expertise measuring and designing the system and then adjusting things to accommodate some aesthetic concerns I had (I have an old historic house with many dormers). They do, like many residential solar companies these days, use a sub-contractor for the actual install, but he and his team were excellent and I would have never have known if I didn't specifically inquire. These also had a production guarantee which some companies did not offer. Be sure to ask the others if they do stand behind their work with the guarantee. It is good piece of mind. Thus, I would highly recommend paying a little extra for Solar Union especially if you job is a little more complicated like mine was.

"Great option to work with HOAs"
Reviewed Dec 05, 2017

“I'm a stickler for details. We knew we wanted solar on our unit. I didn't want to be sold to from a guy who just wanted another install. SolarUnion sat down with us, explained clearly what was involved to install it properly.
When we agreed to do the install, SolarUnion handled all of the paperwork with the homeowners association, permits - all of it, all inclusive in the price they quoted in the marketplace…no curve balls or surprises.
When the guys came out to install it, they were totally professional - and I was watching them every step of the way. It was just installed so properly, and it looks so aesthetically pleasant. They made sure that it looked great.
I always felt that solar was kind of a scam since so many companies do it. But we are generating about 50+ kWh’s on clear days this month. It's awesome. Air conditioner on all the time, and we are netting out a surplus that we can use during the winter months when there is less sun.
They went over and above what is required in a normal install and even painted the conduits to comply with homeowner association.
We totally recommend these guys. Very happy, it was a great decision, and a great investment.”

"I am very happy with my new system from Solar Union"
Reviewed Nov 16, 2017

I sought multiple bids for a home solar power system. Solar Union offered several things that set them apart. First, my contact with Solar Union, Jim, convinced me that they would be able to install the system on a tile roof without damaging the roof. Then they backed it up with a 25-year warranty. Second, they offered high-quality panels and inverter. Third, the company is Diamond certified. Given these three things, and a very competitive price, I chose Solar Union for the project. The initial inspection and subsequent installation went well; the crew worked hard and finished the install in a day and my roof was not damaged. Solar Union then coordinated with the local county inspector and PGE to get my system connected to the grid. Throughout the process, communication (primarily with Dianne) was both clear and timely. We are now generating significant electricity with a high-quality system that is backed up by solid warranties. I recommend Solar Union without reservation!

I can't thank SolarUnion enough! From the initial quote to the solar installation and through interconnection day, the staff was extremely helpful and professional, answering all of my (probably naïve) questions. The team remained in contact with me through the whole process and kept me updated on its progress. They even took the time to show me photos of how they sealed any exploratory holes and took care to ensure the system would hold up over time.
I wanted to add an electric vehicle charging station for my upcoming car purchase and was pleasantly surprised to find out that they were able to complete this job for me as well and bundle it, in house! Combining the projects into one job saved me even more money. Seriously, a great company, great people, great products.

"Solar in Central Valley with MID/NEM 1.0"
Reviewed Oct 02, 2017

We chose Solar Union among many competitors because of their diamond certification, reviews, and good BBB rating. We live in the central valley and have MID as our electric provider. Solar Union made a 1 month deadline to apply for NEM 1.0 which if you understand is a very important thing when it comes to solar. They also promised a 25 year parts and labor with a performance guarantee which is very rare in the solar industry. Our project was accepted and we got NEM 1.0!
Install went well although there were some bumps and mistakes along the way. We were patient with them and they told us they were people of their word and would correct. It took a little time, but everything that wasn't right was made well. Even when this cost the company time and resources.
We finally passed inspection before the deadline and thankfully everything was up and running. Word of note, be active in understanding your electric company's requirements and check with the lead install to ensure smooth functioning here. Each electric company has different codes and requirements so this part is probably the most difficult. It was difficult for us because we had a baby at home and scheduling around his nap times was tough for all parties. But Solar Union did try to accommodate this although it wasn't always possible as there were multiple work days and corrective measures.
At the end of the day, we eliminated our summer electric bills which last year ran $475 and $550 in the hottest months. We are producing excess electricity now and our family couldn't be happier. Solar Union also repaired a few of the Tigo monitoring system components that weren't quite functioning and proved they honor the warranty.
They are overall good at communication and provide quality service. Their price although higher are worth the protection of warranty and handling all problems. We eliminated having an electric bill and Solar Union provided a large enough system to take care of all of our electric needs (pool, large house etc..) So we are grateful to their work to do this. If you are still on fence about going solar understand it repays in 6-7 years or less in most cases and is a sound investment especially when the panels can produce 80+ % even after 20 years! Thank you Solar Union!

"Solar Union is honest and efficient"

What impressed me the most at the start was the straightforward honest pricing of their quote, No inflated costs with big "discounts" for fast decisions. The installation was prompt and professional, and all the specific site issues were dealt with. Performance has been flawless, exceeding our contracted generation capability. My only concern was the "small" nature of the company, and if they would be around to cover the 25 year warranty. I guess only time will tell.

I am always cautious in signing up for anything that seems to be too good to be true, but SolarUnion was thorough in explaining the details and process of using solar energy. Installation was superb. SolarUnion completed the process (paperwork, installation and activated the system) in the time frame they promised. They satisfied all my requests with the installation, including painting the pipes after the installation was complete. Customer friendly and service was excellent. I haven't had an electric bill since the panels were installed 18 months ago with the exception of a negligible service bill through the electric company. I have been selling unused power every month. I have for once and for all switched the sign in the equation...we are now net sellers to the grid. Great investment!

"After careful consideration and TONS of research"
Reviewed Sep 08, 2016

Was initially discouraged by the pressure tactics of solar companies until I met these guys earlier this year. The energy auditor gave me a bid and actually encouraged me to go out and keep comparing. He told me to compare value, quality and performance guarantees then come back to them. I have to acknowledge I had never been invited by a salesperson to stop the conversation right there, go out and compare, let alone in solar.

My only concern was the team’s ability to execute given a couple non-five star reviews I saw from earlier this year (I was in the market for a while), but the team has scaled up significantly. They were able to hit all milestones within five weeks.

"Customer feedback for SolarUnion"
Reviewed Sep 08, 2016

First of all, we were very happy with our decision to transition to solar energy. The savings that we are now reaping definitely outweigh all the time spent researching, negotiating, and eventually working with the selected installer of our solar panels.

Comparatively, for the cost, SolarUnion was a good one in our particular situation. They were able to meet our budget limitations, while having to go the extra mile in relocating an already pre-existing solar pool heater that was located on the roof where the new panels were to be installed. Agreeing to a quote from the original company that installed the solar pool heater would have cost me an additional $1,500 to relocate it.

Except for a cancellation on the original scheduled date for the installation of the new solar panels (because the foreman fell ill and had to go to the emergency room), everything went smoothly as planned. SolarUnion originally installed 33 panels, but had to remove 3 and settle for 30 panels because of city restrictions as it relates to escape routes in case of a fire. Nevertheless, energy production produced by the 30 panels were adequate to met our energy needs.

If not for the for the delay in the original installation causing us to miss work, I would have rated the company 5 stars. As it is, I would rate them 4.5 stars. If you decide to go with this company, talk to Renzo. I commend his professionalism.

I chose SolarUnion after I verified they were a Diamond Certified company.

SolarUnion was large enough to give me the level of comfort I needed that they would stand behind their 25-year output warranty as they advertised, yet still small/boutique enough to take a job that was too complicated for anyone else.

SolarUnion's bid was extremely competitive. I was anxious they would increase the final price based on the challenges of my roof, but they never did.

They were prompt with their install, and everything was done in a top-notch manner. All inspections were passed with flying colors. I am just in love with my solar system.

"Premium solar developer offering a credible performance guarantee"
Reviewed Aug 10, 2016

I wish to commend the team at SolarUnion for the transformative work they are performing in the residential space and for their flawless execution on my PV system.

I must admit to being a CA licensed solar contractor having experience in the utility scale solar power plant fields in domestic and international projects.

With this background and knowledge I approached six local solar contractors for my personal home system. Five of them were solar installers that did not offer performance guarantees…just 25-year product warranties and limited labor warranties of 10 years or under. SolarUnion was the only contractor I found working under the solar developer model. They offered me a 25-year Performance Guarantee, which just blew me away. That operation/servicing agreement alone has huge value. Yet, they offered the entire solution to me plus the performance guarantee at a cost below that of standard solar installers that did not offer a performance guarantee at all. SolarUnion also offered me a roof integrity warranty under the same agreement. They also honored their word and gave me a guaranteed price at the time we signed the agreement so we had no unexpected change orders or cost overruns.

Ivan and Renzo put forward the best qualifying proposal with TrinaSmart modules, which have one the lowest default rates in utility scale projects. They worked with me providing transparency on other components and welcomed my design collaboration all throughout.

Given the attractiveness of the opportunity, I decided to over build the project to provide additional capacity for future electrical vehicle charging or future increased electrical appliance load.

During the entire process, I was kept very well informed and the team was diligent in procuring the permits, utility inspections and final acceptance as well as my rebate supplemental funding.

I happily recommend the team at SolarUnion for your solar investment.

"Good experience up until I ran into problems requiring repairs"
Reviewed Jun 29, 2016

I was initially apprehensive about doing business with this small company that has only been in business since 2011. I initially wanted the supposed long term stability of a much larger solar/roofing company that has been in business for much longer, but SolarUnion totally won me over with their knowledge, patience, responsiveness, selection of top quality components at great prices and a highly competitive bid.

I don't believe it was easy for Renzo Castillo and Ivan of SolarUnion to win my business. Renzo has never failed to be patient to answer all my questions and accommodate my requirements. SolarUnion has earned my business not by slick sales talks but by going the extra mile.

Renzo took the time to explain to me in great detail the reasoning behind SolarUnion's selection of components. Ivan and Renzo have the brains to select components that perform very well, reliably, and are offered at highly competitive prices from manufacturers that are likely to stay in business for many years to come in case warranty issues arise.

Don't let the fact that the modules are Chinese-made scare you. The Trinasmart panels SolarUnion offers perform VERY WELL. Renzo made me a believer in the virtues of a system based on Trinasmart panels and Tigo optimizers. I am very pleased.

About the only drawbacks I can think of with SolarUnion are that subcontractors do all the installation work for them and that SolarUnion is really a small company. SolarUnion doesn't have its own crew of installers, but this is probably an advantage in that it gives them flexibility and be more competitive. The more competitive they are the more likely they will remain profitable and stay in business. I absolutely want my solar installer to be around many years from now when I need them.

SolarUnion is somewhat unique in that they offer a "Trifecta" triple guarantee, which includes a solar energy production guarantee, i.e. they guarantee your solar system will produce a certain number of kWhs every year. It may sound too good to be true, but based on this Trifecta guarantee, SolarUnion would have to replace a very expensive main inverter at their expense if it ever breaks down in the next 25 yrs. It may sound too good to be true, but Renzo confirms in his email reply that this is how SolarUnion interprets the Trifecta guarantee. We shall see if they is really true.

My positive review is a reflection of my experience so far (up to the point of a newly completed installation). It is not reflective of any post-installation interactions that may require warranty/corrective work since I have no need for warranty/corrective work yet. I have every expectation that SolarUnion will stay in business for many, many years to come and that I will be as pleased with them in the next 25 yrs. as I am today.

Update: 11/13/2018
I noticed a water stain due to leak from a suspected solar mount. It occurred in the phenomenally wet winter we had last years. I notified Renzo on October 31, this year (2018) and within minutes received a phone call back from Renzo stating that he would develop a strategy to deal with the problem and respond back in two days. Now, it's been two weeks, without any further reply from him. A company's rating is not only for before and during sales, but it also reflects post-installation responsiveness to repair needs. And in this area, Solar Union is getting a very poor grade.

After several years of contacting solar installation companies I was was pleased to find a company that met all my needs.

I was pleased to work with Renzo Castillo and the two or three others from Solar Union who patiently answered my many questions regarding usage, size, installation and most important cost. Financing was a smoother process than anticipated, installation, which took a bit longer than anticipated was delayed by the county inspection process. Our system has been in place for nearly three months and to tell you the truth I've not even give it an afterthought. I've not had a light bill in this time and hope to make it through Bakersfield's 110 summers with a minimal to no electric bill. Add to the fact that this system should be paid off in 7-10 years, with finance interest payments, because of the PACE program, being tax deductible who could ask for anything more. Personalized service from the start, reasonable cost, excellent design and a solid installation - I highly recommend Solar Union as your next solar installation company.

"Great panel but took forever and needed A LOT of micromanaging"
Reviewed Mar 02, 2016

The short review:
The panels are great, they are extremely responsive to my questions, they were willing to work with me and still return my calls quickly after getting my money. However the process took 4 months and required several nasty emails on my part to get things done.

Long review:
I was looking to have solar panels and an electric car charger installed last year before my second daughter was born in October, but after we sold a condo and got the cash for the installation. After getting some quotes Solar Union had the best price, was the most attentive was willing to work with my timeline and alternative payment schedule, which was awesome.

I called a previous customer and he told me that his recommendation was to have my contract say that if there was a new electric panel or new wiring required as part of the solar installation process, it was going to be Solar Union's cost. That advice probably saved me hundreds, if not thousands of dollars!

I signed my contract in July, and they started the initial design process while we waited to get money for the next steps in August. We had someone come out to see the house so they could draw up plans, and then a week or two later a different guy came to meet an inspector for an initial site inspection. At that initial inspection, the man from Solar Union had not brought a ladder so the inspection had to be rescheduled. The rep from Solar Union seemed very pissy about this and was frankly pretty rude to the inspector.

At the rescheduled inspection a third Solar Union rep came out (he ended up being the head of installation), but our inspector was extremely confused because the plans were drawn up for a different kind of construction that was not relevant to our property. So they needed to draw up new plans and do the initial site inspection again (for those keeping track this is now 3 inspections without anything being done on the house). At both the second and third inspection the inspector was very clear that we would need a bigger, higher wattage electric panel to get the installation approved.

Once we got the money and clearance to start work, we were told by different people in the company that the panels were either in storage, on their way, or hadn't been ordered yet. This lasted for several weeks.

Once installation started, the installers installed a new panel, but one that was the same wattage just larger. They got the panels on and the car charger installed over the course of about a week, but as you could guess the inspector came back and said the panel was too small. So they installed a new one that was THE SAME WATTAGE. Again, the inspector came back and told them it was too small.

At this point it was October, after signing the contract in July, and I was due with my baby.

Two days after coming home from the hospital I had installers here for THREE MORE DAYS installing a larger wattage panel and a larger service connection to the PG&E wires. Then it took another week or two to actually connect to PG&E. So my panels were turned on at the end of October, and I was connected to PG&E in November.

I was put on the wrong PG&E rate, and not told anything about those, but it has all been figured out now and the panels seem to be performing very well.

Overall it was EXTREMELY frustrating and if I didn't work from home the 8 inspections would have been terrible to deal with. However the price was great, the communication is actually great and the panels are working well. Just buyer beware.

I was very interested in going solar this year, and spent a lot of time going through many solar companies on EnergySage. I am glad we picked SolarUnion / FirstPV as our solar installer.

We were time crunched as we had started the process in late March, and I really wanted a system installed before we get to the peak generation months of May-August.

Within a week or so of accepting their bid for the project, SolarUnion was onsite starting on the installation. Their contractor was polite, clean and very communicative throughout the process which took 3 days to finish.

My new Trina panels on a 4.5KW system at my residence in Sunnyvale, CA look great and the install process went on smoothly. We have had about 6 months of good production, and consistent power generation, and I would definitely recommend other folks use SolarUnion for their solar needs.

The only thing I had to pick on, if anything, was that they took 3 days instead of the originally estimated 1.5 days to wrap things up, which was actually due to minor modifications requested by the city inspector.

Very professional, and courteous throughout the process, and the online monitoring offered by them works great too.

I'm delighted with my experience working with SolarUnion through EnergySage. They are extremely responsive, thorough and flexible. The pricing was better than the competition and they deliver more current products with the goal of replacing our total electrical consumption. Other companies merely committed to reducing the bill, not replacing it.

The install crew was timely, thorough and left the job site in good shape. Very experienced installers and electricians. The system looks great and they accommodated some requests for placement of the inverter gracefully. SolarUnion also handled the permit process in my notoriously finicky city without a hitch.

Since installation they have been proactive in monitoring the system and reached out promptly when a minor tuning issue arose. It was promptly and satisfactorily resolved.

I'm an engineer and so was quite interested in the details of the equipment proposal. SolarUnion provided more of that information up front and the components they selected are very good, yet reasonably priced. My friends who work in large scale solar unions responded favorably to my description of the system and the pricing.

Thanks to Renzo and Ivan for delivering a great result!
