To determine the size of the battery you need for your solar system, you'll need to calculate the storage capacity based on your energy usage and desired autonomy. If we repeat the calculations with a lead acid battery, we’ll need a storage capacity of 99.6kWh (33.3kWh x 3 days of autonomy). The 113 kWh Outback Power 48V AGM Battery from SunWatts will meet your needs with capacity to spare.
The size of the solar system you need will be determined by the following factors: Your current and future energy needs. You must consider future purchases or changes that may impact your usage, ie. purchasing an electric vehicle. The space available on your roof.
When sizing a solar system, five basic things need to be known upfront: Your daily energy consumption (in watt-hours), which will determine the number and size of batteries and solar panels required. What percentage of your energy consumption do you want to offset with solar power?
This capacity will allow the solar system to efficiently charge it. 5 kW solar system with a battery — If your home has a 5 kWp solar system, you’ll want a battery capacity of between 9.5–10 kW. Keep in mind that you’ll want to use most of the electricity you generate during the day for charging your battery
10 kW solar system with a battery — The ideal size solar battery for a 10 kWp solar panel system is 20–21 kW, as it’ll be able to make sure the battery is properly charged throughout the day. Which solar products are you interested in? What size battery do I need to go off-grid?
Undersizing your solar power system will leave you without enough power for your needs. Oversizing your system will add unnecessary costs to your budget and can lead to battery issues. In this sizing guide, we discuss how to properly size a solar power system for your home, RV, off-grid cabin or any other space.
