Nationwide Sun

Nationwide Sun is a company that prides itself in acute attention to detail.
Our CEO is a master engineer who oversees every project personally.
We handle everything from design, installation, completion, and warranty repair.
Nationwide Sun is the only company known in California with all the following licensure and capability under one person and company:
A Engineering, B General, C10 Electrical, C27 Commercial Landscaping, C39 Roofing, HAZ-ASB-MLD-UST

Nationwide employs no sales staff; no one is paid commissions.
This allows everyone to focus on what matters the most… the efficacy of the design and performance benefits for the customer.
Our clients often voice how refreshing it is to work with a science-based company as opposed to a sales-based company.

At Nationwide Sun, we focus on doing the best job possible, being honest and transparent. We do not focus on profits, but rather, we focus on building the best product at an extremely competitive price. It is for this reason that we receive an average of 3 to 5 referrals from our customers for whom we have already performed services, some going back over 15 years or more!

Nationwide Sun has installed and maintains over 3,400 systems and has not had one bad review or complaint. We focus on our customer's satisfaction and look forward to focusing on you.

Great experience!

The team at Nationwide isn't huge, and that's a big plus: every employee is skilled at what they do. Their engineering team worked with us to talk through our questions and concerns throughout the whole process--the CEO even replied several times during this process via email to answer our questions. The planning team handled submitting our plans to the county, which were approved promptly, and the solar installation went flawlessly a couple weeks later. Before we signed our contract with them we asked for references, and almost immediately got 3 emails from past Nationwide customers that were absolutely glowing in their recommendations. We're ready to write our glowing review now, too. Kudos to Randy, Jose and his team, James, TJ, Lisa, and Frank for being so prompt and splendid to work with.

Very happy and satisfied customer

Thanks to the entire Nationwide team for a job well done. The entire process from quote to finish have been stress free. Everyone is very professional, courteous and friendly. Always keep me up to date of the process (planning, permitting, installation and inspection). I highly recommend Nationwide and already shared the contact to several neighbors.

Nationwide Sun fantastic value and service for the price.

Had meetings with 3 solar companies and made a decision until a friend suggested I take a meeting with Nationwide Sun. Their proposal was middle of the pack, however the system performance has matched what other companies quoted 1.5x the price to install. Extremely satisfied with system performance and company service. The owner was onsite during my install, which you rarely see these days.
