Four systems. One crew. One warranty.
Every install is designed in-house, quoted as one fixed number, and covered for 25 years.
Rooftop solar
410 W bifacial panels sized to your last 12 months of SDG&E usage. Layout, production estimate, and fixed price before you sign.

What owners report after switch-on
Our July bill went from $412 to $31. The crew was on the roof at 7 am and gone by 4 pm, and the yard was cleaner than they found it.
Helio quoted $2,300 less than two national companies and put the panel layout and production numbers in writing before we signed anything.
The battery kept the fridge, router, and garage door running through the October outage. The app alerted me before SDG&E did.
