The number of solar panels you need depends on battery size, sunlight availability, and system efficiency. For a 12V 100Ah lithium battery, around 400W of solar panels is ideal. Larger systems like 24V, 48V, or 20kWh setups require proportionally more panels.
The capacity of a solar panel to generate power under standard conditions. Example: A 300-watt panel can produce 300 watts of power per hour under optimal sunlight. The amount of energy a battery can store and supply. Example: A battery with 10 kWh capacity can power a 1 kW device for 10 hours.
1,000 Watt hours / 5 hours sunlight = 200 Watt solar panel. 3) Once you have calculated the solar panel as per the above calculations, it''s time to calculate the AH rating for the batteries that might be required for operating the specified load under all conditions. If the selected battery is rated at 12V, in that case:
So, a 12V 100Ah lead-acid battery effectively provides only 600 Wh. The next factor is sunlight availability. Solar production is measured in peak sun hours, not the actual hours of daylight. 1 peak sun hour = 1,000 watts of solar energy per square meter. Example: In Houston, Texas, the lowest sun hours in winter is about 3.5 hours/day.
