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.
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.
Around 250ah of power, ideally a 200ah battery, or 2x120ah batteries. A 500-watt panel setup (2x 250-watt panels) can easily charge a 200ah battery in a day, so you could have 2x200ah batteries charging if you are not running them flat every day.
If you’re running a 1kw continuous load, a 200ah battery will run for an hour, maximum. Ideally, a battery bank of four 200ah batteries with 1kw of panels is best, or around 600ah of battery power. 2kw of panels (8x 250-watt panels, 6x 330 panels, 3x 615-watt panels), and up to ten 200ah batteries.
