Why Senga for solar
Solar that pays for itself. Installed by people you can call.
Since 2016, thousands of rooftops across the Gold Country and Central Valley, and a 4.7-star record on Google. Here is what that buys you.
25-year full-system warranty
Panels, inverters, workmanship and the roof penetrations themselves. If something fails, we fix it. No finger-pointing.
$0 down, two ways to pay
Choose a Solar-Based Utility with nothing up front, or own the system outright with a loan and keep the tax credit.
Local crews, 1 to 2 day installs
Our own employees, not subcontractors. Permits, inspections and PG&E paperwork handled for you.

Savings
Stop renting power at peak rates.
PG&E rates climb almost every year. A right-sized system locks in a lower cost per kilowatt-hour for decades, and most of our customers see the difference in month one.
- Custom design from 12 months of your real usage
- Clear numbers before you sign, including the true-up
- Monitoring app shows production and savings live

How a Solar-Based Utility works.
No panels to buy, no maintenance to worry about. You pay for the power your roof produces at a rate below PG&E, and we handle everything else for 25 years.

Add a battery
Keep the lights on when the grid goes down.
Pair your system with a home battery and the sun you banked during the day runs your home at night and through outages. Under today's net billing rules it is also how you get the most value from every kilowatt-hour.
- Tesla, Enphase, FranklinWH and SolarEdge systems
- Backs up essentials: fridge, Wi-Fi, lights, medical devices
- Often included in a PPA at little or no added cost
25 yrroof penetration warranty
Peace of mind
The longest roof warranty in the business.
Every penetration we make is flashed, sealed and guaranteed for 25 years. Because we also install roofs, we know exactly what a bad solar install does to one, and we refuse to do it.
- 25-year roof penetration warranty in writing
- Roof assessed before design, not after
- Solar-ready re-roof available if yours is near end of life

How to Pay for Solar in Gold Country
Going solar doesn't have to mean a large upfront check. Most Senga Energy customers choose between a $0-down Solar-Based Utility (PPA) and a solar loan. Here's how each option works:
$0-Down Solar PPA
Pay for the power your system produces instead of buying the panels — usually with nothing down.

Own the system, claim the tax credit, and capture the long-term savings.

Straight answers, no sales pitch.
Still wondering about something? Call us. A real person in El Dorado Hills picks up.
Ask us anythingWhat is a Solar-Based Utility?
It lets you go solar with no upfront cost. We install and maintain the system and you pay for the power it produces, usually at a lower rate than PG&E. No ownership, no headaches.
Do I need a battery?
Almost always, yes. Under California's current net billing rules a battery is how you keep the value of your daytime production, and it keeps the lights on in an outage. PPAs can include one at little or no added cost.
Who maintains the solar system?
We do. Solar-Based Utility customers get a 25-year full-system warranty covering parts, labor, monitoring and performance for the entire term. If you buy or finance the system, you receive the manufacturers' warranties plus our workmanship and roof penetration warranty.
What if I move?
Your agreement transfers to the new homeowner through a simple form. We handle the paperwork. No penalty, no fuss.
How long does it take to install?
The install itself takes 1 to 2 days. Permitting and utility approval typically take 30 to 45 days, and our in-house team handles all of it.
