  • "Aggressive follow up"

    Reviewed May 06, 2020

    Really bad sign when you can't contact them before you start.
    Marketing was extremely aggressive...then return calls or e-mails. Not happy. If it's this bad before they start... No thanks.

  • "Change is Good"

    Reviewed Dec 23, 2016

    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"

    Reviewed Oct 28, 2016

    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.
