I am currently working on a project that works with solar panels on Mars and I am trying to calculate how much power I would get from a solar panel on the surface. I have values such as solar irradiance, the area of the solar panel, and the efficiency of the panel. I found one formula: Power=area x efficiency x solar irradiance x performance ratio
However, I cannot find a standard value for performance ratio anywhere and I don't have a reliable source on this equation either, so I can't use it on a paper.
So, does anyone know formula out there that allows me to calculate the power delivered from a solar panel? If so, I would greatly appreciate it and if there is a reliable source (like scholarly paper), please leave a name for that as well.
