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. If you already have solar, we evaluate the impact of adding the Lunar System. Sometimes there might not be any additional savings from adding a battery to your system, in that case no savings will be shown.
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.
Sometimes increasing your battery system size does not increase savings. This behavior is expected due to the minimum bill structures of utilities in some states.
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).
Even without grid power, solar and the Lunar System continuously powers 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.
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.
Suggested system size is chosen based on the greatest savings per kWh from 3 system sizes of 15, 20, 25kWh. The system is configurable to larger sizes.
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.
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.
At Lunar, we want to present you with the all-in system cost, so you know what you’re buying and the value you’re receiving—for everything. You’ll receive final pricing once you connect with a Lunar Install Partner. They’ll provide a quote for the entire system including solar panels, the Lunar System and installation.
