HES Solar designs, builds, and installs the best quality solar systems that produce renewable energy for decades with minimal care, but many solar installers who no longer remain in business have left behind solar systems that might require design improvements, component repair or updates, the addition of panels, or a general evaluation. If your solar installer is no longer around, or if you’ve bought a house with an existing solar system and are looking for a top tier energy partner, HES Solar can cover your solar system in an all-encompassing service warranty package that will optimize your system’s output, reliability, and looks. Regardless of your installer, if you have a permitted system we are the answer to get your solar panels delivering everything you need.
For HES Solar systems, our warranty packages are peace of mind as well as the most cost efficient and time efficient way to ensure your system is always performing its best. When time is money and sunshine is electricity, you don’t want to miss a single day of energy production or go a single minute with a system that isn’t performing ideally for you.

The residential-only entity HES Solar has redefined its scope and has narrowed its focus to home solar service and home battery service. The impact of 2023 California regulations to home solar projects has required this company truncation; we regret the elimination of new home energy installations from our offerings. HES Solar now concentrates on supporting existing systems with maintenance and repair services for HES Solar and non-HES Solar systems and remains available for workmanship warranty work on qualified HES Solar systems.

A note on the state of California residential solar: The residential solar industry has faced significant financial hurdles in the last few years as a direct result of hostile policy, most notably NEM 3.0. Our primary trade partner, SunPower, went into Chapter 11 in August, 2024, and a majority of other solar companies, large and small, have been forced to close, leave California, or restructure. We are glad to remain available as a home energy service group to support our customers and provide maintenance and repair for home systems that have been orphaned by other company closures.
We recognize your frustration with this news and never intended for our beloved 24-year-old residential solar business to curtail its offerings.
