Satellites are powered primarily by solar panels that convert sunlight into electricity, although some specialized missions rely on radioisotope thermoelectric generators (RTGs) for power in deep space or under extreme conditions.

For 500W of continuous power, you need panels that can produce 2,500Wh+ daily (500W × 5 hours). With system losses and variable sun, 400-500W of panels is ideal.

Energy conversion efficiency is measured by dividing the electrical output by the incident light power. Factors influencing output include spectral distribution, spatial distribution of power, temperature, and resistive load. standard 61215 is used to compare the performance of cells and is designed around standard (terrestrial, temperate) temperature and conditions (STC): of 1 kW/m, a spectral distribution close to solar radiation through AM () of 1.5 and a cell temperature 25 °C. The resi.
