Prosolar Systems California

I signed the contract for installing two Tesla Powerwall 3 batteries at my home in mid-November 2024 and my project was completed on Oct 2, 2025 - 10.5 months! Original commitment was to complete the project within 12 weeks (~mid-Feb 2025). Got the run around about shortage of batteries in the market for months. Situation would change week to week. I'll be told they have sourced the batteries and they just need to schedule me, but days & weeks would go by without any follow-ups. Mind you, ProSolar California is based in LA area, and they send installers to the Bay Area to do the work. And, they only drive up north when they have accumulated enough work, which can take weeks to months. It took so long that the original design for my battery installation became outdated since a Gateway was no longer needed for my project - a revision to Tesla design recommendation. That resulted in further delays as City Permit had to be modified and re-approved. Once the installation was complete, I ran into an issue with the battery settings - ProSolar incorrectly set Grid Charging to Restricted. The owner of ProSolar told me it was because of the Investment Tax Credit requirement. This is not true. With Inflation Reduction Act, Grid Charging Restriction was lifted on Jan 1, 2023 - this is clearly disclosed in Tesla’s Advanced Settings webpage that I shared with ProSolar. Despite numerous attempts at contacting the owner over a period of weeks, I never got a single response back. I ended up calling Tesla Powerwall Support team, and they were able to adjust my settings remotely in 5 minutes on the phone. I'm grateful that my project is complete. But, I'm worried that I will be ghosted again by ProSolar if I need any support in the future. I'm giving ProSolar two stars because when they engage with you, the people are nice and courteous. Everything else... BEWARE!

Prosolar California exceeded all my expectations! From the very first consultation to the final installation, their communication was top-notch. They kept me informed every step of the way, answering all my questions promptly and making sure I understood the entire process. The installation team was incredibly professional, working with precision and efficiency to ensure everything was done perfectly. They treated my home with care, and the final product looks fantastic. I couldn’t be happier with my decision to go solar with Prosolar California! If you're looking for a company that values customer service and delivers high-quality work, look no further. Highly recommend!

Really enjoyed working with Patrick Molesworth and the ProSolar Team. Every one of ProSolar’s technicians is extremely knowledgeable and the process was very efficient - only taking 3.5 weeks - from initial conversation and estimate to install, inspection, PTO and turn on. I appreciated the extra time taken to make sure I understood every step of the process and follow up to make sure the system meets my expectations. When you begin to research solar, definitely reach out to the experts at ProSolar. Great value. Exceptional service. ⭐️ ⭐️⭐️⭐️⭐️

Awesome experience from Prosolar! Very efficient and guided me through the whole process of adding Duracell batteries to my existing solar system. They completed the job in one day. Would highly recommend for any solar and battery needs!

Efficient and great communication

Prosolar Installed a new Duracell battery backup for my home. The lead installer communicated the whole process the day of install and answered all my questions. Would highly recommend Prosolar for solar and battery backups!

When I thought about joining solar I had a lot of questions and decided to call and ask questions before I purchased . Regina is absolutely phenomenal, she connected me to Antoinette who made sure she explained everything so descriptive and understandable so I knew what I would be agreeing to before buying . She offered the best customer service and wouldn’t hang up until I properly understood. They proved not only do they care about solar they also care about the customers know what solar is about. 10/10 recommend They have a forever customer with me !
