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?
The size of the solar battery you need will depend on the size of your home — specifically, how many bedrooms it has. To work out what size battery you’ll need, you can start by calculating your electricity usage. Look at either your smart meter or your monthly energy bill, which will tell you how much you use on average.
You need around 400-550 watts of solar panels to charge most of the 12V lithium (LiFePO4) batteries from 100% depth of discharge in 6 peak sun hours with an MPPT charge controller. What Size Solar Panel To Charge 24v Battery?
You need around 1600-2000 watts of solar panels to charge most of the 48V lithium batteries from 100% depth of discharge in 6 peak sun hours with an MPPT charge controller. What Size Solar Panel To Charge 120Ah Battery?
Solar battery sizing refers to the process of determining the appropriate storage capacity needed to meet your energy storage requirements and usage patterns. A well-sized battery allows you to store excess solar energy generated during the day for use at night or during power outages, ensuring a reliable and continuous power supply.
By analysing how much energy you use and when you use it, you can select a battery that can store enough energy to meet your needs, ensuring that your solar energy system operates efficiently and effectively. The desired level of energy independence is another crucial factor.

Solar System Size Calculator: How Much Solar Do I Need?
3. Divide your solar system size (in W) by your desired panel wattage. For this example, I''ll use a solar panel wattage of 350 watts. 3,000 W ÷ 350 W = 8.57 panels. 4. Round up to the nearest whole number. 8.57 rounded up = 9 panels. So, in this example, you''d need 9 350-watt solar panels for a 3 kW solar system on your roof.
