The AC has been running more than we thought because we are all home. Not to mention the pool pump runs all day as well.

Randy was great. Very knowledgeable, and was able to give us a better system for slightly less than the major solar companies quoted us. The installation was quick and easy, and everything has been working flawlessly since. Highly recommend these guys.
