  • "Ultra fast installation!"

    Reviewed Oct 23, 2021

    We contacted multiple solar companies and Nationwide Sun was by far the most helpful with no pressure to buy (unlike other companies). Of the two largest companies we contacted, Tesla was more than $10,000 more and others offered inferior products and warranties. Sun Solar was the other large company and they were more expensive and far less responsive. Both had installation times that were months away.

    Nationwide Sun's estimate came in quickly and the system was a very reasonable price. Installation happened within a week of signing the contract and the system was up and operating in no time. The crew was very professional and did a clean installation. Energy production has been excellent and it appears we'll be at net zero at true-up time. PG&E drags their feet on setting up the net energy metering and billing due to California's solar mandate on new homes and the additional workload they have. That's been the only snag in the process, but is a PG&E problem not one of Nationwide Sun.

  • "Superior Solar Company"

    Reviewed Jul 28, 2021

    Nationwide Sun said they would provide me with the best solar equipment and the best price in there proposal. I got lots of pricing from other solar companies, but Nationwide gave me the best price and best equipment. They are just Superior and the installation of the solar system was perfect and error less. They sized the solar system perfectly because my May, June and July electric bill was Zero, when it is normally $350-$400 per month.

    They are a Superior Solar Company.
