Change is Good

It was important to us that Allterra was the only installer of three final contenders to have so many licensed professionals on board: not only solar, electrical and general contractors, but also every member of their sales staff! While Allterra was not the cheapest bid submitted, it was also not the most expensive. In the end, we were happy to have paid a bit more for knowing an able, experienced stable of professionals did exactly as they promised under the contract. Bravo!

Very professional and competent

I chose Allterra because they were a local company whom I could talk to easily even though their bid was slightly higher than the lowest bidder. However, when compared to the bid by Solar City, Allterra's bid was much better. Approval from HOA took a little time but Allterra was very patient during the entire process. Once all the approvals were in place, Allterra sent very competent people and installation, city inspection and pge net metering went very smoothly.

Aggressive marketing...zero follow up

Really bad sign when you can't contact them before you start. Marketing was extremely aggressive...then nothing...no return calls or e-mails. Not happy. If it's this bad before they start... No thanks.
