What’s the next step to determining the right battery size? Step 2: Determine the size of the load So, let’s say your primary goal is to power critical systems during grid outages. For example, if you have a 10 kWh backup battery you may also be able to use it for solar self-consumption (with the understanding that you won’t get much or any backup power if the grid goes down shortly after your battery has been discharged). There may be cases in which you can use a single battery system for two purposes. However, with time-of-use rates becoming more common and net metering policies eroding across the US, using battery storage for solar self-consumption is gaining popularity as a cost-saving strategy. Historically, home battery systems are most associated with critical loads backup. Self-consumption: Storing excess solar power produced during the day to avoid buying expensive electricity from the grid at night.Whole-home backup: Powering the entirety of your home electrical systems during grid outages.Critical loads backup: Powering a select number of essential electrical systems during grid outages.There are three basic roles battery storage can play: The first step to sizing your solar battery is determining which function(s) you would like it to perform. Next, follow three steps to figure out how many kilowatt-hours of electricity you want your solar battery to hold. So, when choosing a battery size, make sure to focus on the usable capacity. Usable capacity refers to the maximum amount of electricity the battery can discharge at once without exceeding the manufacturer’s recommendations for depth of dischargeįor example, the SunPower SunVault 13 has a nameplate capacity of 13 kWh, but a usable capacity of 12 kWh after factoring in that only 92% of its full capacity can be discharged without affecting its lifespan.Nameplate capacity is the maximum amount of electricity a battery can hold.There are two measurements to be aware of: Home batteries are sized based on how many kilowatt-hours (kWh) of electricity they can store. Team up with an Energy Advisor to design a custom solar and battery system for your home. In this article, we’ll explore the nuances of sizing a solar battery and lay out a process for determining the ideal battery size for your needs. As grid electricity gets more expensive and unreliable, homeowners are using solar and battery systems to reduce their energy costs and keep the lights on when the grid goes down.īut while sizing a solar system is pretty straightforward, choosing a battery size takes a bit of nuance and largely depends on how you plan on using it.
