United Solar in Castro Valley absolutely nailed my solar project! They were super helpful, especially since I have an existing NEM2 system and a tricky tar and gravel roof—no other company was willing to take it on. Their suggestion to focus on self-consumption was a game-changer, and their Enphase system package was top-notch. There was a small hiccup with the system reading the input and output correctly, but even though their team was super busy over the summer, Anahi, Dre, and Ben carved out time to get my system working perfectly. Big shoutout to them for making it all happen! Highly recommend their expertise and customer service!
