Reviews

What customers say

Customers praise the installation crews’ professionalism and communication; one customer says the job was completed in under two days. An earlier customer says the owner helped get a design issue back on track and the company made good on its promise. One customer reported three of ten panels were down for about two months and said follow-up was noncommittal, with the repair still pending.

Customer Reviews

Siddharth Nair

I had a fantastic experience with SimplySolar from start to finish. From my first conversation with David (sales) through installation with Yashar, Najeeb, and Rick, the entire team was thoughtful, transparent, and incredibly professional. David was outstanding. He took the time to walk me through system sizing, storage capacity, and payment options in a way that felt collaborative—not salesy. He was responsive, clear with pricing, and genuinely focused on finding a structure that made sense for our family. At no point did I feel pressured. It was always, “Here’s why this works for you, and here’s why it works for us.” That transparency built a lot of trust. The install team was just as impressive. Yashar, Najeeb, and Rick were respectful of our time, communicated clearly throughout the process, and worked efficiently. The design team was very responsive over email and patient with the many questions I had. When issues came up (like battery placement), they were open to feedback and worked with me to find a solution that maintained code compliance while keeping costs manageable. Installation was seamless and completed in under two days. They clearly communicated whenever power would be shut off and even shared photos of the progress and final setup. Overall, I really appreciate how the team showed up across sales, design, and installation. We’re still awaiting final inspection, but based on the experience so far, I’m confident they’ll stand behind the system if anything comes up. Highly recommend SimplySolar. A truly great experience.

B Sides

Two very different experiences. 1. Installation: Great work! I live in Berkeley so permitting is a pain and requires layers of extra work. Simply solar designed, installed and got the system working flawlessly. They were personable, professional and overall great. 2. Post Installation: It's a roll of the dice. I had a panel go down in the first year and they were on it, emailed me about it and it ended up being a micro inverter I believe and it was fixed in two weeks. Now I've had 3 panels down (10 panel system) for about 2 months which they didn't know about. I e-mailed them in December about it and talked to a customer service guy who was nice but non committal. Then he was let go and now another non committal customer service person took the helm. I'm being told I'm weeks out. I'll let you know when it's fixed.

I shopped around and while Simply Solar wasn't the cheapest they made up for the small increase in customer service. Janet was a gem and very easy to work with even through a few sticky parts. We bought (not leased) our solar and it was done right the first time. Very good communications and excellent onsite vigilant and polite workers. If I had to do it all again I'd pick these guys for sure. Thank you for the assistance, education and expert installation. Two years later everything works like a charm!!
