Frequently asked questions
Can it charge a battery or power a microcontroller directly?
At peak values the cell delivers about 0.15 W (5 V x 30 mA). Output drops in low light, so for battery charging or powering a microcontroller use a charge controller or regulator with energy storage.
Under what conditions are the ratings measured?
The listing states the ratings are measured under standard test conditions: 25 degrees Celsius, AM1.5 spectrum and 1000 W/m² irradiance. Real outdoor output will vary with sunlight and temperature.
