Why Work with SolarUnion?

We Are There When You Need Us – That’s How You Treat Family

We have the best power output warranty in the industry (25 Year Comprehensive Warranty) – You won’t have to suffer through vague, superficial protection. With over 92% guaranteed power output after 25 years, our linear warranty can’t be beaten. That means we set up the system to assure realistic levels of power provided by the life of each module. The modules will be optimally placed with a 25-year roof penetration guarantee. You will also be provided a 25-year extended triple guard guarantee covering (i) parts and (ii) performance of your solar system as well as (iii) the necessary labor for repairs. To make sure your total system is covered, you will have a 25-year extended warranty on the inverter (the brain of the system), and a 25-year workmanship warranty on it. The package is fully transferable if you sell your home. Our clients are also given ownership from day 1 with these extended warranties on parts, workmanship, and system performance — we are a centralized source of warranty, service, training, and support. Just call our 24/7 customer line(888) 815-6633.

"I highly recommend this company."
SolarUnion is one of the very few companies that will install solar on a foam roof. Their team was incredible in the way they staged the project and worked together with the roofing company. First the roofers ripped off my old composite shingles and repaired the roof. SolarUnion installed brackets that anchor the solar panels on the bare plywood base. The roofers came back to spray foam to seal the brackets and completed the foam roof. Then SolarUnion came back to install the panels on the brackets that were now sealed in with foam. I'm telling you, this company goes the distance. The team at SolarUnion was magnificent in every way. From the first contact with Karissa, the sales rep who explained everything from the get go, to Andreis and his crew who gave 110 percent in getting everything right during the process. All the while, Itzel, the project manager oversaw the permits and checked in to make sure things were going smoothly.
