  • "Great Contractor!"

    Reviewed Apr 11, 2021

    It was my original intention to obtain three quotes for installation of my residential solar system. I first contacted Sunrun through Costco. My experience with Costco's in-store salesman was generally positive. That's where the positivity ended - right there in the store. He then scheduled a virtual presentation with their technical staff. That presentation did not go well. The technical staff member started off on the wrong foot by asking me to provide info I had already submitted on-line and emailed to the in store salesman. Then she asked me whether I would like a quote for an outright purchase, a loan or a lease. I requested quotes for all three so I could compare alternatives. She said her software could only provide one quote, not three. During the next hour, I asked numerous questions, many of which the tech salesperson was unable to answer (including why she was proposing to place solar panels on the north facing roof of my home). I followed-up our virtual conversation with a detailed email requesting further information. I never heard from Sunrun again.

    For my next quote, I reviewed solar contractor recommendations on the social media site Next Door. After seeing several positive recommendations for NexGen, I decided to contact Owner Eric Helgeson. He promptly scheduled a virtual meeting with me followed by an in-person meeting at my home, at which time his accompanying staff members surveyed and measured my roof in preparation for coming up with a proposed solar layout. Within a few days, Eric presented me with several digital layouts with different panel quantities and locations. Eric then worked closely with me in coming up with an economically optimal design - not one which overproduces more energy than I need at my expense. He also presented battery options to me, but noted that a battery basically doubles the price of the system, while only providing limited back-up power for essential electrical components during an outage. Eric made it clear that purchasing a battery may not be in my best interest given its very high costs. He suggested a better option might be to install a battery at some future time when costs are likely to drop. Costco/Sunrun did not do this. They only tried to sell me a complete system with a battery at double the price. Once Eric and I agreed on an efficient design, the final price was a few thousand dollars less than Costco/Sunrun's quote (excluding the battery). Eric also uses better quality Enphase equipment and installs micro inverters at each series of panels instead of a single micro inverter for all the panels as Sunrun was proposing (a less costly approach for them but not for the consumer).

    So now, per my original intention, it was time to obtain quote No. 3. However, I was so pleased with Eric's professionalism, honesty and integrity, that I decided to speak to three local references of recent NexGen installations. All were very pleased with his work and had only positive things to say about him and his crew.

    Instead of getting a third quote, I called Eric and told him the job was his. The contracting process was seamless with all documents being signed on-line electronically. Once the contract was signed, Eric handled all the City permitting and coordination with SCE.

    After the City permit was issued, NextGen's crew began work and completed the project in two and a half days. They showed up at my home at the agreed upon time each morning and cleaned up the job site each day before leaving. No problems arose during the time they were at my house and there were no change orders or other surprises.

    When the job was done Eric took the time to answer all my questions and also showed me how to use the Enphase app. The app is very user friendly and can be downloaded onto your smart phone, tablet or computer.

    My system has now been operating for two months without any problems.

    If you are considering the installation of a solar system, I highly recommend you give Eric a call. He and NexGen will not let you down.

    I cannot say enough great things about NexGen Construction. From the initial informational get together to the installation and final debriefing, NexGen Construction knocked it out of the park. Eric and his team are genuine, approachable and honest. I work the night shift and they went out of their way to accommodate my sleeping pattern and my crazy dogs antics. Eric was able to personalize the solar system, payment plan and installation to my family and my needs and schedule. If you are looking to install solar panels, look no further, you cannot go wrong with NexGen Construction!

    Reviewed May 01, 2019

    From the very start Eric was honest, patient, and knowledgeable about the whole process. I had already gotten 2 other quote from other solar competitors and Eric was never pushy and always willing to answer any questions I had regarding my possible installation. When I finally decided to move forward with solar I knew Next Gen was who I was going to go with, from his friendly service, to his knowledge on the products and of course this price as well. His installation team was very polite and friendly, always cleaned up there mess every day and made any adjustments to my system as I requested. Over all I am clearly happy with the service I’ve received from Next Gen and would definitely recommend them to all my friends and family. Last note… After completion I asked him to review another property I have downtown HB, after he reviewed it, he came to the determination that it would be in my best interest financially to obtain the solar at that house do to location, roof space, and my ROI (return on investment) one last reassurance that Eric is a very ethical man and will not take to work without letting you know the facts.

    Thanks again,

    NexGen was recommended by a friend. They were professional and timely throughout the entire process. They took care of everything, and made everything easy. Eric is very enthusiastic about his business and his products. It was a pleasure.

    We had solar electric for our home and solar thermal installed for our pool. I am attimate about getting what I pay for. NEXGEN presented a good explanation of how things would work, was at my home when they were scheduled and completed the 2 installations without a hickup. I would recommend NEXGEN to anyone considering solar or thermal and looking to save money.

  • "Great experience with NexGen"

    Reviewed Feb 12, 2018

    I have talked with multiple solar providers over the last 15 years. Every time the price was more attractive. Several times I was close enough to making a decision that I used Yelp to check out the vendor. I read plenty of horror stories that made me put off making a decision - people not showing up, nobody returning calls, installers where nobody on the crew spoke English, etc.

    I picked NexGen because their Yelp reviews were stellar (check them out yourself) and I felt that Eric (the president) was a no BS guy I could count on. He didn't disappoint me. My installation started on Thursday morning and by Friday afternoon I was making electricity. The NexGen crew was a great bunch of guys. Everyone spoke English and happily answered any question I had. The installation is very clean looking with wiring going thru the attic instead of strung across the roof like I've seen with so many other solar installations.

    The following Monday Eric came by to show me how to monitor my system and answer any remaining questions I had. The HB city inspector came by the same day and signed off on everything. I can't believe how quickly this all happened. I have total confidence that this guy is going to be there if I have any problems. He always answers his cell and there is no runaround when you try to reach him. The ball is now passed to SCE to do their thing with my billing.

    I would recommend NexGen to anyone.

  • "NexGen is the best"

    Reviewed Oct 31, 2017

    We were motivated to look at solar after purchasing a townhome that our son and his family live in. The townhome is all electric. We interviewed a number of companies and we were so impressed with Eric at NexGen that we put solar panels on both the townhome and our two story single family home. Eric did an amazing job educating my wife and me about all the options in products and design. Eric worked very closely with us getting the needed approval from the HOA for the townhome and obtaining the permits needed from the city. The solar panels have exceeded expectations. I highly recommend that folks seriously consider solar panels and when you decide to move forward, I highly recommended you call Eric at NexGen. Eric and his team of installers are terrific.

    I started looking into solar in 2013. By chance the first company I contacted was NexGen Construction. At the time I was in the investigative phase, not anywhere near ready to commit to an installation.

    Eric, NexGen Construction's owner was very helpful in educating me on solar. He spent this time helping me come up to speed even though he knew I was not ready even to decide if solar was right for me much less sign a contract. This was in June. I spent that month and July checking out installers and confirming that solar was a good investment for me. I winnowed down companies to three candidates.

    NexGen Construction gave me a good deal. But more important the dealing with them both in my investigative stage and in the purchasing process made me feel confident in their product and service. I felt it important that my provider was a full service company, not a contractor who relied on fleeting subcontract labor.

    It is five years later when I write this review. Three of my friends have also used NexGen Construction for their solar installations. I believe they have also passed down the recommendation to their friends. All of us are totally satisfied with the work and product.

    The system has consistently been out performing its estimates by somewhere between 5 and 20 percent a month. My electricity costs are essentially nothing now, so I am saving over $2000 a year. This is based on the cost of electricity five years ago. I have not recomputed based on today's rates, but rest assured the savings are greater now. These savings are equivalent to a tax free investment that returns better than 10% a year. Where else can you find that kind of a safe investment?
