It feels good knowing that when we charge our car or cook dinner, we’re using the energy created right here at home. We’re not pulling it from oil or gas; we made it.”

Design your System today

Designed in California.

Built for everywhere.

Every part of the Lunar System was developed and tested in Mountain View, California and assembled in the United States. Lunar was founded by a team that helped pioneer home solar and battery technology, with deep roots in hardware and software from the companies that started this industry.

Design your System

In Placer and El Dorado Counties, your Lunar battery now works overtime: protecting your home during outages while saving you on utilities and earning you incentives during peak demand. New battery customers can take advantage of a 30% tax credit or start with zero money down. That’s smart energy that pays for itself.

Just add solar panels to make, use, store and control your own energy – day and night, foul weather or fair.

Provide a few details to help your installer from Hooked On Solar design the right system for your home.

In Alameda County, your Lunar battery now works double duty: protecting your home during outages while earning you incentives during peak demand. New battery customers who install or already have solar qualify for up to $2,160 upfront and $864 in annual payouts, 
on top of your monthly utility savings. That’s smart energy that pays for itself.

How are these figures estimated?

‍Benefits of your System

1st year savings 

We determine your potential 1st year savings by comparing your current annual energy bill with a potential bill after installing solar and the Lunar System. 

To calculate your annual energy bill, we assume an energy rate plan based on the major utilities in your state and evaluate your annual solar production profile based on your zip code. For solar owners in California, we use NEM2 tariffs, and for those without solar, we use NEM3 tariffs.

Hours of backup

To estimate the hours of backup, we divide the total usable capacity of the battery by the consumption rate (total annual consumption divided by hours in a year).

Endless backup 

Even without grid power, solar and the Lunar System continuously power your home. So long as the sun shines, you can recharge your Lunar System and power on. Increased energy usage or unfavorable weather can, however, affect the duration of your backup power.

Opportunity to earn cash 

The Lunar System includes software to participate in Virtual Power Plant programs. You can get paid every time you contribute power from your Lunar System to the grid during emergency load reduction events. Terms and conditions are set by your installer or grid services provider.

Energy bill estimate & solar system size

Energy bill estimate

Based on your state and the approximated square footage of your home, we estimate your total annual energy consumption. We then take the average energy cost in your state to calculate your monthly energy bill. This is an estimate that can be adjusted.

If you already have solar

To suggest your solar system size,  we generate a total annual production (based on the average solar irradiance of your state) equal to our estimated total annual consumption of your home. If you manually adjust your solar size to a larger option, we adjust your total annual consumption accordingly, to maintain 100% sizing. If you decrease your solar size, we maintain the total annual consumption we estimated, and an undersized solar is used.
