Bill successfully navigated our first system when we moved into the property. However we found our usage exceeded the system capacity so we added more panels with a battery. With the upgrade, our true up bill went from $500 per month to near $0 and now have battery backup in the event of an outage. Great work overall!

Solar professionals are often asked: "do you have solar on your home?" In fact I have placed it on 3 of my homes including this Vallejo installation in 2021. By the numbers: PPA contracted production 8100 kwh annual; actual 2022: 9109; actual 2023: 8257. Average performance 7% above contract. No service issues. Happy solar camper!

When deciding to get solar we interviewed a few companies in the beginning. We really felt that Bill knew his product from the inside out, and how to get us any rebates available. Plus he was friendly, honest and professional. All the timelines he gave us were spot on and we are very pleased with the installation and help we got throughout the process. We felt his recommendations were based on our family's needs. He continues to touch base with us and we have been grateful for his service and are very happy with our system. I feel I can refer him to my clients without hesitation, thank you Bill Brittan!

Bill turned out to be a great partner. Without pushing his business on us, he showed many different options to us. He then offered a great deal and most importantly he was constantly in touch with us to make sure that everything is going smoothly. I would highly recommend him.

William (Bill) Brittan came across as a very diligent and informative sales person. He did a very job of explaining the nuances of the solar setup, and set the right expectations from cost point of view.
When there was a delay in installation, he stepped in did his best to get the work started. Also visited us during the installation. Also connected me up to his other customers to avail the group discount and so that I can get access to a electrician.
Bill is very pleasant person and always available.

Bill did a great job in helping us to make the leap to solar power. He has been in the business for a long time and is extremely knowledgeable. He explained the system concepts in layman terms and we appreciated his gentile nature. I have recommended him to friends several times because his quiet, low key nature is refreshing. We have saved a lot of money with our solar system.

Bill was the Solar City consultant for my solar installation. He addressed my questions well, both technical and contractual, and made sure that all aspects of the project, including estimating, design, specification, installation, interfacing with PGE, and inspection moved along smartly. I have been very pleased with the result.

The recent power outages prompted us to consider installing solar panels even though we had very little knowledge about them. Bill was the right person for us. He is affable, an imaginative problem-solver, and has extensive solar experience as well as a lot of patience. He thoroughly explained our options along with the pros and cons of each. He answered or got answers to our questions without trying to steer us. After they were installed, he helped us select the appropriate PG&E plan. In other words, he was with us from start to finish and beyond. Based on our experience, we recommend Bill to anyone exploring solar options.
