Low Cost Solar Panel with Concentration
The increasing electrical power demand onboard telecommunication spacecraft’s leads the solar generator industry to develop new types of solar arrays. Progress in the field of high efficient photovoltaic cells give new insights for the solar power generation, but those new elements also bring new constraints from both technical and economical points of view.
The cost of a solar generator is dominated by that of high efficiency GaAs cells. Using concentrators means using fewer cells to deliver the same power.
