Fun, Responsive, and Reliable

“Super highly recommend! Allterra Solar was great to work with at every step of the process, super responsive to my 1 million questions, worked with me to get the system to do what I needed, and they had fun doing it.”
– Elisha W., Santa Cruz, California

Professional and Timely Panel Reinstall

“Thank you, Allterra, for your professional excellence on my solar panel removal and reinstallation. You removed the panels within two weeks or so of being notified of the start of a reroof project and replaced them in about a week of its completion. Everyone involved with the project was knowledgeable, helpful, and friendly.” – Lee S., Boulder Creek, California

Powerwall Install and Seamless Backup

“Allterra installed our solar system several years ago. It works great. We added two Tesla Powerwalls 2 to the system and the appropriate controls a few weeks ago. They installed them in one day and did a very professional job. We are using them as 100% storage and have had to use them several times due to power outages. They seamlessly switched to the batteries and worked well. We highly recommend Allterra Solar.”
– James T., Half Moon Bay, California

Beautiful Design and Smooth Process

“Allterra did an awesome job installing solar on our mid-town farmhouse. The array is beautifully designed and is producing well beyond our expectations. Every step of the process, from the initial site visit until PGE permission to operate was smooth and easy. Allterra arranged a low-interest loan from Mosaic for us, helped us with the paperwork we needed for our tax rebate, and made sure we understand our solar monitoring.”
– Salamander B., Santa Cruz
