  • "Great Experience Quick to Install"

    Reviewed Jul 17, 2022

    I had a great experience with the team at Nationwide Solar, they were responsive in giving me a reasonable quote and I was amazed how fast they moved from when I signed the contract to when they installed my stem. Frank was great when he came to my home to verify if solar could be put on. Ryan and Michael and all of the installers were great and told me what was happening as they went. It took about two weeks from signed contract to Nationwide Solar to install my panels, they handled all of the inspections with the City and I just received my PTO today less than a month from when they finished the install and had the final inspection. I would recommend Nationwide Solar I was glad I was able to find a local installer that did all of the work in house. What sold me on this company was being local, did not have pushy sales people, and Frank and the rest of his employees knew what they were talking about.

  • "Great Customer Care"

    Reviewed Jun 17, 2022

    I can’t recommend NationwideSun enough to anyone who is considering getting solar installed. They went through the whole process so you know what to expect and when during the installation and after.

    Their price was more than competitive, and for me, what made them stand out from the long list of other companies was their customer service.

    Whether it’s Michael (project manager/sales) or Ryan (GM) you deal with, they are prompt, responsive and just want to make sure you understand fully any given situation and are completely satisfied. I could pick up the phone and they’d be on the other end with answers immediately. No call centers or having to leave messages hoping that someone will return the call.

    Lastly, my neighborhood’s HOA management company is the absolute worst. They misplaced documents, asked for duplicates, and often failed to respond to calls or emails. Michael always had a cool head and would supply them with whatever they requested and in a timely manner.

    I couldn’t be happier or more confident in recommending NationwideSun.

    Reviewed Jun 11, 2022

    Not all Solar companies are the same, I have searched for long time and viewed many solar companies before I found Nationwide Solar Company out of Rocklin, CA. Ryan Castillo, Michael Bush and Jose Cortes are great team to work with, they are so prompt in delivering and answering every question I had about Solar systems, they are very professional and quality people, I have nothing but to praise for the knowledge and the ability to answer all my questions and being there through the process from start to finish. I’m very pleased with my selection to work with this company, I highly recommend them, thank you all.
