You need around 200-300 watts of solar panels to charge most of the 12V lead-acid batteries from 50% depth of discharge in 6 peak sun hours with an MPPT charge controller. So, a 12V 100Ah lead-acid battery effectively provides only 600 Wh. The next factor is sunlight availability. 1 peak sun hour = 1,000 watts of solar. . This calculator simplifies the process of determining the optimal size for solar panels based on specific battery specifications, including ampere-hours (Ah), voltage, battery type, and the charge controller type. "Peak sun hours" don't mean how long the sun is visible in the sky.
