We speak

English

As we are giving 25 year workmanship warranty. IntegrateSun has setup after sales services offices in Texas & Georgia. They are only being used for aftersales purposes.
IntegrateSun usually takes 6-8 weeks to install residential solar panels if no permits or HOA approvals are required. If permits and/or approvals are required for the property location, then the timeline will increase depending on the speed of the process
You can call us at 855-999-1850 or email the project management team at pm@integratesun.com. We will resolve the problem under our 25 year workmanship warranty.
We prefer the solar panels which are made in USA and have long life of at least 25 years with backed manufacturer warranties. We offer Qcell, Silfab, Aptos ,REC, Mission Solar panels and more!

Reduce your reliance on the grid by generating your own electricity with residential solar systems. During outages, you’ll enjoy the benefits of the power stored in your system, and in the summer when your A/C sends consumption soaring, the extra power will be a welcomed relief!

Avoid if you're in the DMV

(Update on 16 Sep 2026: Over a year since my last update. Guess what? System STILL not working. Turns out the original site survey was bad and they installed equipment NOT compatible with my electric grid, which caused all these issues for years (yep I can say "years', it's been more than a year). In fact the original installation was so bad, Enphase (the equipment manufacturer) let their CEO know. The workmanship was so terrible and "dangerous" that an independent contractor IntegrateSun hired to fix everything refused to do the work. They found someone willing to removethe incompatible component about 6 months after the problem was identified, that was last week. They didn't put everything back right and the system still isn't working. I've reached out to the city government to get them to do something last time and I'm not afraid to do that again. I know you're reading this, Enphase. You reached out faster the last time I updated my review.)----------------------------------------------------- (Update on 5 Aug 2025: third time is not the charm, inspector showed up on 28 July and left because the installer with the paperwork didn't bother to show up. I have a job, I'm yet again left wasting my time-off on this. On 4 Aug 2025 at 1 PM, the proj manager texted me to say the inspector would show up the next day from 8 AM to noon...again less than 24 hours notice. Once again this solar panel installation is negatively affecting my livelihood, my job, my ability to make money.)----------------------------------------------------- (Original update) It's been almost a year since I signed on with IntegrateSun. The system is in service but I'm STILL not done. I was assigned a project manager but don't expect to hear from them after your deposit unless you constantly ping, they are not pro-active. My almost hundreds of emails and text messages that show me initiating contact over the span of the last 10-12 months can more than attest to that. Would they even have done anything if I hadn't sent them weekly emails for months on end asking for updates? It was just crickets after I paid the deposit. No kidding, I was resigned to thinking I had been scammed because nothing was happening and I didn't hear anything for such a long time. Once they do get in touch, they give you appointment times (not offer, give) for the many many times when an installer or an inspector needs to show up...pretty often without real pre-coordination. Sometimes I got a message the day before or even THE DAY OF to inform me that someone would be showing up. Excuse me, people have jobs and need more than a few hour's notice to take time off to deal with this. What the heck? Even better, on more than three occasions, NO ONE showed up at the appointment times and I ended up taking off work for no reason. The last two times the city inspector came to check on their work to sign off on the permit, but the hired guy didn't have the right paperwork. This happened TWICE. Luckily it was early in the morning so I could still go to work and get paid. The good thing is that the panels showed up and they work but the principle of dragging this on for almost a year...possibly more since it's still not done. It's literally unprofessional, completely beneath what one would expect from a professional service. It's not worth the slightly cheaper price, I would've paid thousands more to avoid this neverending nightmare. My neighbor across the street had their system installed from start to finish in about 3 months. I'm here holding the bag.

Worst company I have ever dealt with

This company has to be the absolute worst company I have ever dealt with. From timelines that were nowhere near realistic, to switching people I was working with, to weekly "updates" on my phone that were so garbled that even the voicemail transcript couldn't figure it out and would just write complete gibberish, to switching solar panels from what was advertised and agreed upon, to subcontracting with "installers" who left garbage and little bits of wire everywhere on my patio and worked inside of a live panel without proper safety equipment and concern for the dangers of electrocution. Let alone I now have a leaking roof once we finally got rain here 5 months after the install. I have been paying for electricity as well as for this system since December and I still don't have an operational system! To which their reply was that they cannot control the electric company's timeline... Except that they could have had the installation pass the inspection the first time as any reputable installer would have been easily able to do, instead of having it fail 3 times!

Integrate Sun Solar Panel system

The company did an excellent job in installing and making sure I understood what the system does and how to monitor it online. The Project manager did an excellent job to make sure I could monitor the system online and that I understood what the system does and how to monitor it. The company was very accommodating to my needs and broke down all the jobs they accomplished in my home. They installed new control panel, solar panels, batteries, electric car charger and put an electric outlet in my front gate for the gate opener I am purchasing. Everything was in the contract and they did all the work promised and clean up afterwards. The installation took a little bit longer than the three days but considering the amount of work they did, that was very reasonable. The crew provided daily progress reports to ensure I understood what was accomplished on a daily basis. I definitely made a great choice when I decided to go with Integrate Sun to do the work. I started my project with EnergySage and need to compliment them making it easier to look at all the Solar companies and their review on their site. thanks everyone for all the good information and hard work you provided.

Great Solar Company

Excellent experience with IntegrateSun! The team was professional, knowledgeable, and kept us informed throughout the entire process. The installation was smooth, completed on time, and the workmanship was top-notch. We're very happy with our solar system and highly recommend IntegrateSun to anyone considering going solar.
