How to Use the "How Many Solar Panels Do I Need" Calculator
Enter your power station's capacity and your location's typical peak sun hours, and the calculator finds the total solar panel wattage needed for a full daily recharge, then breaks that down into how many common panel sizes (100W, 200W, or 400W) that would take.
The tool is built to translate a capacity and a sunlight assumption directly into a practical shopping target.
Finding your real peak sun hours
As covered in the recharge-sizing guide, checking a solar insolation map for your specific region gives a more accurate peak sun hours figure than the generic default — this single input has a large effect on the final recommended wattage.
Checking against your power station's input limit before buying
As covered in the max-solar-input guide, always confirm the recommended wattage doesn't exceed your specific power station's maximum solar input rating before purchasing panels, since exceeding it provides no additional charging benefit.
