yes, and yes.You are talking about heat being a bad thing in solar collecting..yet the design generates heat does it not?
there are many factors to concider.and what type of temps are we talking?
Talking about string wiring and affects due to shading.you also taked about different wiring methods for arrays can you elaborate?
yes, and yes.
there are many factors to concider.
One test we did based on irradiance alone on a typical sunny daywith some clouds were:
43deg C at 875 Irradiance (more clouds)
45.8deg C at 891 Irradiance (less clouds)
This was the Module temp.
Talking about string wiring and affects due to shading.
Strings are wired in series. So are cells in each module. Shading one or two cells in one module can greatly reduce that modules output (this is dependant on how many bypass diodes are in the module).
And, so shading one or two modules can greatly reduce the output of that string.
Irradiance are we talking the amount of the intensity of heat on the surface of the units? and at what point of intensity do we start to actually start to cause lose?
