Why Allterra

Allterra Solar delivers trusted expertise, top-quality systems, and long-term value—backed by over 15 years of local experience.

Our Story

Allterra’s distinguishing factor is its unique approach to business and solar. Allterra focuses on providing the best solution for every client. That is why Allterra is a proponent of owning your solar system rather than leasing it. Other solar companies tend to recommend PPA or lease agreements because they are easier to sell. Letting a finance company own the equipment limits homeowner’s options and provide only a fraction of the benefits owning does. Allterra will sell you solar if you are a good fit. As a referral-based business, customer loyalty is critical to our continued success.

Internally, Allterra strives to create the best working environment possible. We believe the people at Allterra are integral to Allterra’s success. We offer healthcare, retirement savings, paid time off, competitive wages, paid driving time to and from job sites, and routinely have staff appreciation events to acknowledge team members doing great work. It is a balancing act to reward staff for great work and reward clients with great services and prices. We hope Allterra exemplifies a better way of doing business where the community involved is part of our marketing plan and support for other locally owned businesses is part of our procurement approach.

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
