A typical lithium-ion solar battery can store between 10 to 15 kilowatt-hours (kWh) of energy, while lead-acid batteries usually hold up to 7 kWh. The storage capacity depends on battery type and size.
For example, average residential solar battery capacity ranges between 5 and 15 kWh. So, If you have a 10 kW sized solar battery, considering 90-95% DoD, the reserved optimum kW of energy it holds for you to use is around 9 or 9.5 kWh per day.
So, If you have a 10 kW sized solar battery, considering 90-95% DoD, the reserved optimum kW of energy it holds for you to use is around 9 or 9.5 kWh per day. Electric consumption above this level requires several or more efficient large battery systems or external grid connections.
Here's how we can use the solar output equation to manually calculate the output: Solar Output (kWh/Day) = 100W × 6h × 0.75 = 0.45 kWh/Day In short, a 100-watt solar panel can output 0.45 kWh per day if we install it in a very sunny area.
This does not directly tell you how much energy the battery can store, but can be a more useful value in deciding how long a circuit will run from a battery. For example, a car battery might be rated for 50 Ah. That means in theory it could source 50 A continously for 1 hour and then go dead.
We will also calculate how many kWh per year do solar panels generate and how much does that save you on electricity. Example: 300W solar panels in San Francisco, California, get an average of 5.4 peak sun hours per day. That means it will produce 0.3kW × 5.4h/day × 0.75 = 1.215 kWh per day. That's about 444 kWh per year.
For instance, a 10 kWh battery lasts longer and provides enough power to run home appliances for several hours than a 6 kWh battery. However, remember that not all the stored energy in a solar battery is usable, as you have to consider there is a depth of discharge (DoD) feature.
