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!

Utter Disappointment with Integrate Sun

Signed contract February 2025. Paid 30% when permit was applied for. Paid next 50% in April because "the panels will be in next week." County permit signed 5 May 2025. AEP said no communication for six months voided our connection application. Panels delivered on 10/31 in Texas by a guy from Virginia who rented a truck from Enterprise Rental who had never handled solar panels before, bringing them from their "warehouse" on the east coast. Two panels short of a full load. He made 3 previous stops in Texas before our house. 11/11 installers showed up with electricians who said they drove over 3 hours to be here. Passed Tesla test; panels received energy, battery stored it. System turned off, to wait for next 2 panels. 12/23 delay, delay, delay. Questions abound: Does Integrate Sun know what they are doing? Why are we on our third project manager? Why does Energy Sage trust them as a provider? Can we have a class action suit to deal with binding arbitration? Why does Integrate Sun keep losing employees? What is our recourse to compensate us for losing the $8,000 federal income tax credit? You ask about the quality of the materials; we don't know; they won't let us use them. The system is licensed through Tesla in Integrate Sun's name. Lost solar power we could have had for last half of Nov, and all of Dec. We have emails detailing stalling.

Cannot Recommend

At this point, I cannot recommend this company. Things seemed to be going well at first. Frequent communication early on, all permitting and other arrangements were taken care of. Once things reached installation, there were many problems and delays, and inconsistent communication. When the system was finally up and running, it turns out it is configured incorrectly, and that has yet to be resolved. The original estimate was 60-90 days, and it is currently approaching a year.

Easy to reach when we had questions throughout the process. Very friendly staff. Were able to get our system installed in time for the year end deadline.

The Excellence of IntegrateSun

I am so glad I went with IntegrateSun to install my solar panel system. After being screwed by a “cowboy” outfit, I contacted IntegrateSun to see if they could make a particular deadline — which I knew would be quite a challenge. They said they would do everything they could to make it happen. Sure enough, they made the deadline, saving me thousands of dollars. They didn’t put a foot wrong throughout the whole process — from outlining my options all the way through to installation. Everyone was completely professional, honest, available for communication, and transparent. The installers were personable, friendly, courteous and helpful; I would have trusted them as babysitters. Even when I had a question after installation and payment, the project manager responded to my query and explained the situation. I can’t say enough about how pleased I am to have bought my system from IntegrateSun. No regrets at all. I only wish all companies were as honest, professional and efficient as IntegrateSun!

Unfriendly, forceful, unhelpful, unresponsive.

Do not use IntegreateSun, the salesperson was rude from the start, he tried to show me the stock price of one of the battery pack makers in an attempt to dissuade me from using one of IntegrateSun's competitors, then he quoted me on the same system the competitor was suggesting. The salesperson was difficult and always dodged direct questions when I had them, he was difficult to get in touch with and missed one of our meetings. He quoted me on a solar array that generates way more than I need and when I asked him about it he then preceded to lie to me about how long it would take to use Solar to charge the battery he was quoting me, when I asked for the math and for an explanation about the setup he gave vague answers and blamed me, saying I asked for that system. My impression of IntegrateSun is that they are pushy and eager to sell you whatever system they can without considering your needs. When you consider how much money we're spending I would strongly recommend going with a company that answers all your questions and gives you all the feedback you need to make the right decisions instead of just trying to push you into a sale.

Hoping for installation by December 31.

I have noticed that the owner has personally responded to several negative reviews. I have sent an email to pm@integratesun. I hope this review will get their attention! I signed a contract on August 26, 2025. Approvals obtained November 13. Panels were supposed to have been shipped last week, but told late Friday that shipper having problems. Almost out of time and stand to lose almost $11,000.00. At this point I am willing to pay extra to expedite the shipping/and/or get a different shipper. Would even consider traveling to Houston from Florida and renting a U-Haul to bring the panels here. Owner, you have written a lot of good stuff about your company. Please prove it by getting my panels installed by the end of the year!
