The more surface a satellite solar panel has, the more sunlight it catches and thus the more electrical power it generates. In order to fit a satellite in a launcher, solar panels are folded together (''stowed'') to the side of that satellite. Once the launcher has reached the desired orbit, the satellite is released and the solar panels are ...
Although solar PV could be a sustainable alternative to fossil sources, they still have to deal with the issue of poor efficiency. Although it is theoretically possible to get the highest efficiency of 29% in commercial PV, this value only reaches a maximum of 26% in the actual case. 8 Various external and internal factors are responsible for the degradation of PV panel …
