Easy to work with and responsive to all questions, before and after the installation. Knew all the regulations, Fed, state, and city so there were no surprises in terms of cost. Worked well with the roofing company in terms of setting a schedule. Did the work quickly and cleaned up after themselves. Set up the app for me.

Keenan S and the SunPower team were the epitome of professionalism throughout the entire process of quoting, planning, installing, credits and rebates. To the penny, SunPower's quote was accurate. From our $1000 SunPower cash-back to our tax-rebate, everything went perfectly. Keenan is a great representative who believes in his company, says what he is going to do and does what he says.....as good as it get. Thank you Keenan!

The Solar Technologies staff worked hard as a team to deliver a great product from planning to sales, permitting, installation, and inspection. The project manager gave us timely updates on the process for our installation. The solar panels and battery storage have acted seamlessly to transition to backup power when we have had grid power outages due to planned and unplanned PG&E outages. The apps available for system monitoring give a record of power usage for the solar panels and battery. I highly recommend Solar Technologies for a custom solar project.

The whole team was very professional starting with the sales and engineering staff in dealing with pandemic related delays. As part of the original contract, Solar Technologies also arranged for a new electrical panel with an excellent contractor. The solar system installers did a very clean installation with no problems and the city inspection went without a hitch. Overall, a great experience and a great job.
