How PowerStack™ Works

PowerStack™ is a solar+storage system designed to help you save money on your energy utility bill. It does that by making affordable, reliable and clean solar power available all day long, even at night.

01

Sunlight hits the solar panels,
producing clean, renewable energy.

02

Some of that clean energy powers
your home during the day.

03

And some of that clean energy is stored
in the battery to be used at night.

04

At night, your home runs on
the stored energy, powering things
like lights, TVs and air conditioners.

05

Your home will be connected to the
grid for the times when you need
extra power.



Benefits

PowerStack™ is available as a lease with no money down and low, fixed monthly payments. It also comes with an industry-leading, 25-year warranty. But that’s not all. Here’s what else you can expect with PowerStack™:

When you sign up for the Sunnova PowerStack™ Plan, you have the option of including an escalator in your solar service agreement. The purpose of the escalator is to provide more significant savings in the early years of your agreement. You’ll pay a lower initial rate per kWh in return for a slight increase in your rate each year. The following illustration compares monthly payments over 25 years with and without an escalator.

Production, Storage and Consumption

As a solar+storage system, PowerStack™ is designed to meet most of your everyday energy needs. While solar is a renewable energy source, there is a limit to how much your system can produce and store on any given day.

Like all solar power systems, PowerStack™ produces more energy on a bright, sunny day than on a cloudy one. It also will likely produce more in the summer than in the winter, simply because the days are longer. So, your solar system production will vary based on weather and other factors.

The battery, or storage part of PowerStack™, works a lot like the battery in a phone or laptop. Once it’s full, it won’t take any more electricity. And when it’s empty, it won’t have any energy to give.

We’ve designed the PowerStack™ according to your average monthly energy consumption, maximizing your solar energy use and replacing much of the electricity you would normally draw from the grid.

 

PowerStack Consumption

 

We understand there’ll be days you’ll need more energy than usual. For those days, your home is still connected to the grid and you’ll use electricity from the grid.

 

1 Your solar system’s production will vary based on weather and other factors. Utility rates and utility rate structures are subject to change and cannot be accurately predicted. Your electricity usage may also vary from month to month. Projected savings from your solar system are therefore subject to change. Sunnova makes no guarantees regarding credit for net energy exported to the electric grid, and any credit provided (now or in the future) is subject to change or termination by executive, legislative or regulatory action.

How PowerStack™ Saves You Money

PowerStack™ offers solar energy day and night at a price that’s lower than what grid power costs. And, because you keep all the solar power the system creates, solar becomes your home’s primary power source, and the utility grid becomes your supplemental electricity source.




How Two Bills Add Up to Savings

There may be times when you need extra power than what PowerStack™ can provide. For those times, your home will use power from the grid to keep the lights on. That means you’ll still be a utility customer and you’ll still get a monthly bill from the utility, even if you don’t use any power from the grid.

Since most of your home’s power will be provided by PowerStack™, the amount of power you take from the grid should be considerably less than before. Your smaller utility bill, plus your low, fixed PowerStack™ bill should result in real savings.1
