How long to charge a power station with solar
Pick a station, your panel watts and your state.
State figures are yearly averages for one city in each state on a panel tilted 20 degrees, worked out with NREL's PVWatts. Flat panels, shade and cloudy seasons give less.
FAQ
What is a peak sun hour?
One hour of sunlight at full test strength. A day with 5 peak sun hours delivers the same energy as 5 hours at full strength, spread across the whole day.
Why not use the panel's full rating?
Heat, angle, dust and cable losses keep real output below the label. This calculator uses 75% of the rating, and the station also caps what it accepts.
