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!

professional team from start to finish

We recently had a solar system installed by IntegrateSun, and although we ran into a few post-installation issues, the team went above and beyond to make things right. I truly appreciate their commitment to customer satisfaction. Special thanks to Irfan (Project Manager) – he was always responsive, transparent, and made sure every concern was addressed promptly. He coordinated everything professionally and never made us feel rushed or ignored. Also a big shout-out to Niang, who came out for the second service visit. He was thorough, knowledgeable, and took the time to explain what needed to be fixed. His attention to detail and friendly attitude made a huge difference. The system is now performing perfectly.

Professional and responsive

They did a good pre-engineering job, handled the paperwork, scheduled the installation, met all requirements, and the system is now fully functional.

Slow, poor communication, mistakes

Aryan Lee was the project manager for my project. He specifically asked me to mention him by name. I was happy with how things went up until we had approval to actually start tangible work. There were delays in the equipment arriving. Who knows why. The installers they sent were not company employees. They subcontracted pretty much all of the work. That seems normal, but they said in the documentation that they submitted for permits that there were no subcontractors. This caused a few problems. The subcontractors didn’t begin work each day until between 10-noon. They could come one day and not the next. What amounted to maybe a day and a half of work took more than a week. Another problem was that they did not know how to get the app working. They had to send another person on another day for that. On one occasion, they sent someone to our house without telling us. My wife was home and we had no way of knowing if he was legit and he wanted to work in the garage. Not a good situation. The solar was finally working in early November. But they failed inspection with the local utility inspector five times. It turns out that the problem was paperwork, not a material or safety issue. But that still caused the final approval to take an extra three months and one day of PTO for me from work. The company refused to compensate us for this delay. The only other thing this company has in the positive column from my experience is the cost. They were 20% cheaper than the next option. But maybe I got what I paid for.

Excellent Solar Installation/Support Experience with IntegrateSun LLC With Faris

This is an update on my experience with the support I got from the IntegrateSun support team. I worked with Faris for 2 support issues which got resolved very quickly and efficiently. My Critterguard came out due to heavy storms in our area and Faris arranged for a tech to come out and get that fixed. While they were fixing the critter guard they saw that one of the panel had a crack and Faris and the team got that replaced very quickly. I would rate the support I got from the team at 5 stars. I had a fantastic experience working with IntegrateSun LLC for my solar panel installation. From start to finish, the process was smooth, professional, and handled with great care. A special thanks to Hamza Hassan, the Project Manager, who was instrumental in making the entire installation seamless. Hamza was knowledgeable, communicative, and consistently went above and beyond to ensure everything stayed on schedule and met expectations. His attention to detail and commitment to customer satisfaction truly stood out. There was a minor delay on getting the panels due to manufacturing constraints but he still kept me updated on the overall status which helped. The team at IntegrateSun demonstrated professionalism and technical expertise throughout the project. The installation was completed on time, the county inspection has been completed and now we are just waiting for the final PTO from the utility company. I would recommend IntegrateSun LLC to anyone considering solar energy solutions—and if you get the chance to work with Hamza Hassan, you're in great hands.

They Made it Right

Updating my original review because IntegrateSun ultimately came back and corrected the issue, and that genuinely changed our opinion of the company. Our project started off rough. Communication during the installation phase was frustrating, and we ran into a major issue where our home’s solar-ready conduit setup was not used as discussed, resulting in unnecessary drilling and installation concerns. At the time, it felt like we weren’t being heard, and for a while, we were extremely disappointed with the experience. However, once a more senior project manager, Areej, became involved, the experience changed significantly. Communication improved immediately, there was a clear effort to understand our concerns, and most importantly, the company followed through and corrected the installation properly. To their credit, they ultimately did the right thing and resolved the issue in a way we’re happy with. That matters a lot, especially on a large project like solar, where unexpected issues can happen. No company is perfect, and I still think there are areas where IntegrateSun could improve internally, particularly around project management consistency and communication during installation. But I also think it’s important to acknowledge when a company steps up and makes things right. At the end of the day, we’re happy with the final outcome and would encourage others to give IntegrateSun a chance.

Integrate did a great job selling and installing solar at my residence. The quality and professional installation were great. Gu Xing my project manager was very helpful all the way thru the process. My only issue was the project from start to finish took very long.
