GreenStar’s conduct is utterly unacceptable, and I strongly advise against engaging with this company. Despite their claims of operating with honesty, transparency, and respect for homeowners’ decisions, my experience was entirely contrary. Their representative, Mike, was aggressively pushy. We expressed our desire to cancel the solar installation well before it began, but Mike insisted that since we had acquired a water softener, we were obligated to proceed. We clearly stated our preference to switch to another company and offered to pay Gary, the owner of the water softener company, for the system. However, Mike demanded a $14,000 cancellation fee for the solar installation, despite the fact that it was neither installed nor scheduled.
GreenStar employed scare tactics, and whenever I raised concerns or issues, they promised internal investigations that never resulted in any resolution. Mike falsely guaranteed a tax credit that would be given to the company to reduce costs, which was misleading. Additionally, GreenStar’s claim that installing solars with them would eliminate the electricity bill was a blatant falsehood. Instead, we are now burdened with both a solar payment and an electricity bill. When we confronted Mike about this discrepancy, he dismissively stated that everything was functioning correctly and questioned why our bill was so high, which was incredulous. I urge you to save yourself the headache and choose a different company. We are currently in the process of seeking legal action against GreenStar. Their actions directly contradict the values they advertise, and conning homeowners through fear and misinformation is neither ethical nor professional.

Greenstar Power installed solar panels along with a new roof on our home in Leander. Just an incredibly great group of people to deal with. And they do know their solar, folks! The new roof and the solar installation were expertly done -- and quickly. Since then, any questions we have had have been answered by Nathan, and all the representatives who have come by to check/confirm the operation of the panels and equipment have been knowledgeable and courteous. Great product and great customer service. We have saved a fortune on our electrical bill.
