You want a solar panel that will charge your battery in 16 peak sun hours. To find out what size solar panel you need, you’d simply plug the following into the calculator: Turns out, you need a 100 watt solar panel to charge a 12V 100Ah lithium battery in 16 peak sun hours with an MPPT charge controller.
You need around 600-900 watts of solar panels to charge most of the 24V lithium (LiFePO4) batteries from 100% depth of discharge in 6 peak sun hours with an MPPT charge controller. Full article: What Size Solar Panel To Charge 24v Battery? What Size Solar Panel To Charge 48V 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?
Battery Capacity x Voltage = 150Ah x 12V = 1800Wh. Required Solar Panel Size = 1800Wh / (5 hours x 4 hours) = 1800Wh / 20h = 90W. So, you would need a solar panel with at least 90W capacity to charge your 150Ah, 12V battery in 5 hours, considering 4 peak sun hours per day. Solar panel sizing is crucial in designing a solar power system.
You need around 175 watts of solar panels to charge a 12V 60ah Lithium (LiFePO4) battery from 100% depth in 5 peak sun hours with an MPPT charge controller. Full article: What Size Solar Panel To Charge 60Ah Battery?
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).
