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!

Excellent Service

I recently had solar panels installed at my home by IntegrateSun, and I couldn’t be more impressed with the entire experience. From the initial consultation to the final installation, the Areej Joseph team was extremely professional, knowledgeable, and transparent. They took the time to explain every step of the process, answered all my questions, and provided clear updates throughout. The installation crew arrived on time, worked efficiently, and maintained a clean and respectful work environment. The system was installed flawlessly, and everything was tested. Overall, I’m very satisfied with the quality of the equipment, the smooth installation process, and the outstanding customer service. They also collaborate with a third-party loan company that funded part of the project which save me from the stress of looking for a loan company. I highly recommend this company to anyone considering solar for their home.

Excellent Solar Experience with Integrate Sun

Like many people this year, I wanted to install solar before the credit ends on 12/31/25. I have a fairly large, all electric house with two electric cars and I thought a solar system would be too expensive. Integrate Sun was able to give me a very good deal that made sense. I had a great experience with them and the whole project was managed very well by my project manager, Lily Garcia, who was always very responsive and friendly the entire time. There are a lot of moving parts with a project this large and she handled everything very efficiently. We passed the inspection on the first try and even my usual master electrician said the job was done very professionally compared to installations he has seen from other companies. I highly recommend this company for all of your solar needs.

Still Waiting for Installation

I signed with them in early July 2025. As of December, I am awaiting installation I have had 4 different project managers. Each time I have been told that the prior left with medical issues. Nearly every deadline and milestone has been missed. The communication and project management have been terrible. I even had to tell the project manager and senior project manager that all of the equipment had arrived and requested installation. -Half of it had been stored in my garage from a surprise!/no notification shipment for a month before the rest arrived. Will adjust this review if things get moving along soon.

Customer support (Faris) super responsive

I had a minor issue with my Tesla power wall - Faris was really helpful in getting the issue resolved and promptly sending a technician on site to check it out (turns out it was a software issue!).

Still not complete after 9 months

I have been patient with this company.It's been over nine months since we started this journey.My my solar system was installed in july due to multiple issues.From incorrect placement, needing re permitting and reinstallation of components.And now missed opportunities for current inspections.I still have yet to have my system completed.I don't know what else I need to do to get this company to help me finish this project.But i'm currently not happy with the progress that it's been. From the delays on their end, I lost over two months of full operating potential and had to pay pg&e yet again. I hope that they are able to get this completed. In a reasonable amount of time.

(*Update*: recent improvements) Months of Delays, Poor Communication, and Repeated Errors

*Update* After posting this review (and many attempts to get answers), the owner reached out to us directly. She committed to having our project completed by the end of the month and has been proactive in working through the remaining issues. She has already identified and corrected several mistakes before the delayed panels arrive, and for the first time in this process, communication has been consistent and solution-focused. We recognize and appreciate this renewed effort. While the earlier stages of the project were extremely frustrating, the owner’s involvement has been a meaningful step in the right direction. We are cautiously optimistic that the project will now be completed as promised. ------------------------------------------------------------------------ Our experience with IntegrateSun has been extremely disappointing. The project has suffered from months of repeated delays, inconsistent communication, and major management issues. First, it took over three months just to get the city permit approved — not because of the city, but due to repeated submission errors from IntegrateSun’s own team. Even after that was finally resolved, the problems continued. We were told multiple times that our materials were “in stock” and “scheduled for delivery,” but more than a week after those assurances, there was still no shipment or tracking information. Every few days we’re told the same line: that tracking details will be shared “as soon as they’re available.” Nothing ever follows. We made a significant payment only after receiving written confirmation that the equipment was ready to ship — a statement that turned out not to be accurate. Now, the installation is still not scheduled, and we are at risk of missing the federal tax credit deadline, a potential $12,000 loss to us. We’ve had to escalate multiple times just to get basic updates, and even then, we receive vague or changing explanations. If you’re considering IntegrateSun, be extremely careful: Get every timeline commitment in writing. Verify that materials have actually been ordered before paying. Expect to manage the process yourself if you want it to stay on track. We hope the company improves its internal processes, but based on our experience, the lack of accountability and communication has been unacceptable.
