Top Quality People & Equipment at a Great Price

Someone once told me, when making big investments in your home, it's not just the cost, but who is doing the work. That has been proven to be true many times over, and yet that is only part of the reason why I chose Nationwide Sun for investing in roof and solar for my home. You will not find better people. Not once did I talk to a sales person, because they do not have them. I talked to experts in various areas of the project, as well as the president of the company, who came to my home personally multiple times. I do a lot of research and I ask a lot of questions. This company has one of the longest records of any, and the record is spotless in almost 20 years of business, not a hint of a complaint. They use top quality components and materials. They told me that they would not be the lowest cost option, but they beat the quotes from companies that use the same level of components. They offer the longest and best warranty, and they stand behind it. During the early phase of my project, one of their clients had tree limb crash through their roof during heavy storms and they jumped into action, on a weekend, to remove the branch and patch the roof until they could repair it permanently after the storm passed. No hidden charges, if something goes wrong, they will come and address it. That is who I want doing the work on my home. Good people, doing good work. Supportive with great, responsive communication. This company is diversified and will be around for many years to come (unlike many solar companies who folded this past year). They did great work at a great price, and they will be there if I need any assistance. That is why I chose Nationwide Sun and why I recommend them.

Contented Customer

I chose Nationwide Sun after comparing several contractors with the help of energysage. I wanted a company that was local and experienced. They were not the cheapest, nor the most expensive. Everyone I dealt with was professional and knowledgeable, from the design team to the installers. I am happy with our decision to let Nationwide Sun handle our installation and delighted with our utility bill.

Chose Nationwide Sun via Energy Sage

I hesitated before finally submitting my December 2022 PG&E bill to Energy Sage to elicit bids from solar installers. My husband and I were experiencing an inexplicable doubling of our energy usage and going solar was a last resort solution. Then, overnight, bids started coming in. Three promised to cover 100% of our needs. It was only on closer examination that I realized that would require 35 panels and and the removal of our 50-year-old Chinese Elm. Two others took a bit longer but had clearly spent time considering our situation: only one suitable site, a south-facing garage roof. Both provided schematic layouts. Both promised to cover only 46-48% of our needs. One of these two companies was Nationwide Sun, a local company owned and run by engineers. Follow-up consultations, during which we provided them with a summary of our energy usage over four years, and the discovery that our elevated electric usage was the result of a sub-slab leak of electrically-heated hot water led Nationwide Sun to promise 129% coverage with 18 panels. The hot water lines have been repaired, our electricity needs are more than covered by our solar array, Nationwide Sun has proven more than worthy, Energy Sage was the matchmaker!

Good quality work in timely manner

I was a bit nervous considering new technology and big investment for me. I got an honest advise from Nationwide Sun not to install storage battery in the beginning. That saved quite a bit of money. Their quote was reasonable considering that I chose to install one of the best solar panels and inverters. It was very easy working with all staff members of the company from the very beginning to the end. They are clear in their communication and kept me informed about each step in the process. Overall project execution was efficient, hassle free and done quite professionally. I have referred Nationwide Sun to my friend and recommend anyone to hire them for the solar project.

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.
