How much current does the solar panel charge the battery

For most real-world setups, a good rule is: use 100–200W of solar to reliably charge a 12V battery (like a 12V 100Ah) if you want daily recharging, not just maintenance. For simple battery maintenance only, 10–30W is often enough. Adjust for sunlight hours to find daily charging duration. . How to calculate charging time of battery by solar panel? Divide the battery's watt-hours by the panel's wattage, then add 20% to account for power loss. Factor in 20–30% efficiency loss from heat, wiring, and controllers. [PDF]
