How this example is calculated

This illustration assumes a solar payment 38% below your current bill, fixed for 25 years, and a utility bill rising 6% annually. It excludes residual utility charges, incentives, fees, maintenance, system degradation, and financing terms. It is not a quote or a savings guarantee. Your proposal will use your utility, roof, usage, equipment, and eligible plan.

More from the power you make

Keep the power.
Make it work for you.

Your solar does more when you can choose when to use it.

After sunset

Your solar.
On your schedule.

Save excess daytime solar for the evening. Use more of the energy your roof makes instead of sending it away and buying electricity later.

When the grid goes down

Keep the essentials
running.

Plan backup around what matters: refrigeration, lighting, internet, and the loads your system can support. Choose the right capacity for your home.

During expensive hours

Take the pressure
off peak rates.

With a compatible time-of-use plan, use stored energy when utility prices rise. The opportunity depends on your rate plan and daily energy use.

Day and night

Make it by day.
Use it at night.

The roof works while the sun is up. The battery covers the house after dark.
