The Complete Off Grid Solar System Sizing Calculator

Step 1: Determine your Daily Energy Consumption. The primary factor determining your off-grid system size is your Daily Energy Consumption, measured in Watt-hours (Wh) or kilowatt-hours (kWh). 1 kWh = 1,000 Wh. The higher your daily energy usage, the more solar panels and batteries you''ll require.

Solar Sizing Calculations & Worksheet: Calculating Battery Run Time and Recharge Time

So our 100W solar panel will likely produce 70W. Using our formula, we can calculate recharge time by dividing 400Wh (battery capacity) by 70W (solar output). We get an approximate recharge time of 5.7 hours. If we want to charge our solar generator in less time, we can get an additional 100W solar panel.

What Size Solar Panel To Charge 100Ah Battery? (Calculator

Time To Charge = 100Ah × 12V × 0.9 / 400 Watts = 2.7 Peak Sun Hours. As we can see, a 400-watt solar panel will need 2.7 peak sun hours to charge a 100Ah 12V lithium battery. If we presume that we get 5 peak sun hours per day, we can actually fully charge almost two 100Ah batteries (or one 200Ah battery).
