Doing nothing costs
$235,100.

That's what a typical Southern California home on a $320 bill hands the utility over the next 25 years. Solar and a battery for the same house is about $26,100 — and you own it. Move the slider to see your own number.

A Southern California desert home with rooftop solar at dusk

It's handled.Since 1970.

National installers come and go — and their warranties go with them. We're three generations of the same family, answering the same phones in the High Desert, with 5,000+ roofs to show for it. Your system is our license, our crews, and our 25-year promise.

Before you sign

Why replace one rising bill with another?

Homeowners get pressured into 25-year leases and PPAs every day without being told what they're really agreeing to: a second bill that climbs every year, and a contract attached to their house. We don't sell escalating leases or 25-year PPAs. We never have. Every route we offer ends with you owning the system.

Tax credit gone? You still have options.The federal solar tax credit may be gone, but your chance to own solar isn't. Ask about our 25% Discount Program (Tax Credit Replacement) for eligible homeowners.

Don't sign anything until you know:

  • Is the system actually large enough?
  • Will it cover your future electrical needs?
  • Is a battery required?
  • Will it perform the way you were promised?
  • Are you overpaying?
  • Would a lease or PPA cost you tens of thousands more over time?

Good questions

Asked all the time.

We put our customers on annual billing, so credits you build in summer carry forward against winter. Most months you then pay very little — often just the fixed charges — and the energy side of your account settles up once a year at true-up. A well-sized system can finish that year at zero energy charges, or with surplus credit paid out at the net surplus rate. Two things never go away: the fixed monthly service charge, and the per-kilowatt-hour non-bypassable charges on power you import. Credits cannot be applied to either, which is why we will not promise you a zero bill. The number that matters is lifetime anyway. Ask what you will pay your utility over the next 25 years; for most California homeowners it runs well into six figures, and you never get it back.

Own it — and we mean own it. What we don't sell is the escalating lease or the 25-year PPA, where you get a second bill that climbs every year, a contract attached to your house, and nothing you own at the end. Nearly every solar horror story we hear starts with one of those, or with an installer who vanished. Our own prepaid PPA is the opposite: one payment up front, no monthly payment, no escalator, a 25% discount off the price on day one, and the system transferred into your name at year six. And because it is already paid for, there is no payment stream for a buyer to assume if you sell before then. If financing is the hurdle, $0-down ownership options exist. And we'll tell you straight if solar isn't right for you yet.

Yes — this is a whole pillar of what we do. We diagnose, repair, and take over long-term support for orphaned systems of any brand: panels, inverters, and batteries included.

With battery backup, your essentials keep running automatically. Without one, grid-tied systems shut off for line-worker safety — one big reason we design solar + storage together.

We do. Our own C-10 & C-46 licensed crews handle design through commissioning — no subcontractors, no finger-pointing.

Yes — full EPC for rooftop, ground-mount, carport, and battery storage up to megawatt scale, including utility interconnection and permitting.
