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 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.

Solar in the Desierto de Sonora, Yuma AZ

I recently completed a 9.3 kW rooftop solar installation with IntegrateSun, and the experience has been excellent from initial design through commissioning. With 35 years of construction project management experience, I tend to evaluate contractors on technical accuracy, communication, and execution. IntegrateSun performed at a level that met — and in several areas exceeded — my expectations. System Design & Engineering The design team provided a clean, well thought out layout that maximized roof production while respecting structural and electrical constraints. They were transparent about equipment options, code requirements, and utility considerations. I appreciated that they were willing to discuss conductor sizing, inverter behavior, and load side vs. line side interconnection details. They treated me like a partner, not a passive customer. Project Management & Permitting The project development team kept the process organized and predictable. Permitting, utility documentation, and AHJ requirements were handled efficiently. Communication was consistent, and I always knew what stage the project was in. As someone who has managed complex construction timelines, I can say their coordination was solid. Installation Quality The installation crew delivered clean, professional workmanship. Conduit runs were neat, penetrations were properly flashed, and the electrical work was tidy and code compliant. They were open to discussing grounding, bonding, and monitoring placement, and they respected the fact that I had technical insight to offer. The final product looks good and performs as expected. Performance & Expectations The system is now online and producing well. Based on the process alone, IntegrateSun has earned a full 5 stars from me. But solar is a long term asset, and post installation support is just as important as the initial build. I plan to update this review over time as I evaluate system performance, monitoring reliability, and IntegrateSun’s long term service responsiveness. Bottom Line If you’re looking for a company that delivers solid engineering, clean installation work, and professional project management, IntegrateSun is worth considering. I would recommend them based on my experience so far.

IntegrateSun was a very easy management firm to work with for the installation project. Quotes were accurate, updates on progress were effective, and the installers did an excellent job.
