Photovoltaic Panel Temperature: Average in Normal Conditions

[xharville]

I was wondering if anyone knew the average temperature of photovoltaic panels assuming normal conditions.

It would be the same as any other material of the same albedo in the same area. How much sunlight, wind, etc. it's exposed to are the determining factors.

There are no 'normal' conditions, it depends entirely on the operating environment. Since their efficiency falls off dramatically with increasing temperature, they're usually designed to be optimally cooled, in terms of radiation, convection and conduction. They're also designed to ensure that they only absorb what radiation they can convert to electricty; anything converted to heat will decrease the efficiency of the cell.
