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!

No installation but mostly satisified with final outcome

IntegrateSun offered a very competitive quote for excellent solar equipment with great warranties, and Hani was helpful in discussing potential designs for our system. This, along with the excellent reviews on Energy Sage and Google, was why I chose to work with them. Our timeline was tight for completing the project before the 12/31/25 tax incentive deadline, so I was impressed that we had our site visit less than 48 hours after signing the purchase contract. Luke was very pleasant and efficient in completing an assessment of our property. Like many people in 2025, we hoped to get our system in before 12/31 to qualify for the 30% Federal tax incentive, which didn’t happen. I was unhappy to be strung along even into December, but I greatly appreciate the patient and thoughtful response by the project manager supervisor to my concerns, and was satisfied with getting most of our deposit back.

Strong Finish After a Rocky Start with Integrate Sun

I am revising my initial negative review after Integrate Sun completed my install today, 3.24.2026. I signed my contract on 9.15.25, for perspective on how long the process takes - just a little over six months from contract to PTO. Ultimately, I am satisfied with their work. Deliveries and deadlines are a real challenge to navigate and if your experience is like mine, you're not going to always know when things will happen, but in the end they did a good job. Raoul, the installer they contracted with to actually do the install and Supervisor Areej stepped in to get my project completed after a very rocky start. Their pricing is very sharp, but just be aware, for that lower price vs the competition you will need to be VERY vigilant in your follow up and communication to get a 5 star outcome like I did. I would use them again, but just being honest, it was a challenge to get to a quality final product.

Adventures in Solar

We started our journey in late 2025. It was a little rocky but I have feeling political.conditions in the country impacted our installation more than anything else. Throughout the entire process our Project manager Lily remained patient, and empathtic. Without her im not sure we would have made it to the finish line. Now that our project os wrapped up im grateful for her. Qe have our beautiful panels

IntegrateSun delivered as promised

Gu Xing and IntegrateSun successfully installed a completed solar system on my residence in the San Francisco Bay Area on a tight deadline and before the end of year. Gu always followed up via text and email throughout the project keeping me informed of permits and installation dates. I would recommend them for your project.
