If you're setting up a solar power system, knowing how many panels you need to charge a 100Ah lithium battery is key. A 12V 100Ah lithium battery contains 1,200 watt-hours (Wh) of energy (as 100Ah × 12V = 1,200Wh).
What this implies is that you need to produce a minimum of 1,200Wh of power through your solar panels to charge the Solar Battery 100Ah completely. You must, however, account for efficiency losses in the system.
Selecting the right size of solar panel
Solar panels from SM Solar are available in various wattages, usually 100W, 200W, or 300W. How much sunlight you receive (in peak sun hours) has a vast influence on how much power your panels can generate. Most locations receive about 4-6 peak sun hours daily.
Here's an approximate calculation of how many solar panels you'd require:
· 100W solar panel produces approximately 400-600Wh per day (assuming 4-6 sun hours). Two to three 100W panels would be required.
· 200W solar panel produces 800-1,200Wh per day. One or two panels would suffice.
· 300W solar panel produces around 1,200-1,800Wh per day, so a single panel may be adequate in sunny regions.
Including efficiency losses
Solar systems are not 100% efficient because energy is lost through charge controllers, inverters, and wiring. As a safety factor, it is a good practice to install 20-30% additional panel capacity for Lithium Battery Singapore. If you estimate you need 200W, for example, buy 250W-300W total so you can fully charge.
