Solar Recharge Calculator
Estimate the solar energy and peak-sun-hours needed to refill a power station.
Estimated peak-sun time3.4 hoursEstimated days at your sun assumption0.9 days
Important electrical limit
This calculator estimates energy only. Before connecting panels, verify the power station’s maximum solar voltage, current and wattage limits and the panel array’s open-circuit voltage.
Real-world solar
Cloud cover, panel temperature, shading, orientation and season all reduce harvest. Using a 70–80% system factor is more realistic than assuming nameplate panel output for every hour of sunlight.
