    Solar Vast Team was completely great. They did not pressure me and explained everything extremely well. We kept wondering why we received other quotes cheaper . But after being educated on the different type of Solar Panels and being shown the durability and quality of the Sun Power Panel. We are very please and happy with the decision we made my proceeding with Solar Vast.
    They provided us with a rebate and we have received 3 referral bonus since our neighbors have elected to proceed with Solar Vast. A true company that keeps there word!!! Keep up the amazing work...
