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!

Recovering from a bad experience

It's been challenging to work with IntegrateSun. The install in 2024 took 7 months and multiple attempts to pass inspection with repeat findings. I've had no issues with the system after the install. Recently I struggled to get a quote from them to remove and reinstall the panels after my roof sufferred storm damage. I previously posted an honest and very negative review. The company reached out and resolved the issue. I'm a firm believer that we will all mess up. How we respond to it makes the whole difference. I'm adjusting the rating in faith that they will live up to their promise.

Delays and Outright Lies

I couldn't be any less pleased with my experience. Delays from project manager Hesham have led to me losing out on the 30% tax credit. He's been caught in several lies regarding progress, including stating that permits were paid AS I SAT IN MY CITY HALL confirming they were not. Lack of prompt ordering of panels have led to two redesigns of my system, causing further delays. Lack of having an engineer stamp on the design submittal delayed it further. I've had 47 solar panels taking up space in my garage for months, as well as all of the other equipment. The panels arrived at 10PM with no advanced notice, and have taken up my garage entirely. Not contacting my utility company (despite saying they did) also delayed it. I've asked for his supervisor and their legal department multiple times, and they have ignored it each time. I've requested that we speak through email due to what I'm sure will be a lawsuit, and they switched to calling. I requested a new project manager several times, which has also been ignored.

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.

Company Interaction.

The overall experience was good, even though I didn't go with this provider, I would still recommend those I did communicate with..

Installing Solar panels on the roof

We used Integrate sun for our roof solar panels. The Project manager, Irfan, was very attentive with our needs and kept us informed all the way. The process had some hiccups that were beyond his control. First he received the wrong panels but was able to fix it by getting us better panels within the same price. Than installation took a longer than projected time frame due to the weather conditions and Winter holidays. Overall, we are very happy with the company and the customer service

Up and running, great communication throughout!

I had the pleasure of working with Lily at IntegrateSun throughout the entire process of getting solar ordered, shipped, and installed on my home. With any obstacles that came our way, Lily was prompt and effective with communication, never leaving me feeling left in the dark about next steps in the process. She did a great job of walking through the process during what I have to imagine was a very busy end-of-year install period! All said and done, I'm very happy to have my new system up and running. Thank you very much Lily!
