What Kind of Place Would be Better Place for Building Solar Power Station?

In China, I give you a definite answer: Qinghai-Tibet Plateau and Inner Mongolia. 

From one character of solar cell, temperature coefficients(Gintech solar cell): Isc=0.050%/℃, Voc=-0.341%/℃, FF=-0.114%/℃, Power=-0.424%/℃. If you don't know what is filling factor(FF), never mind, but you would concern for the power. Obviously, the higher temperature there (solar power station), the power is lower. On the other hand, the parameters you find on label, is under STCs ( 1000W/㎡, 25℃, AM1.5). So when the temperature of solar module is 75℃, you will get 78.8W from 100W. It would be a fatal reduction to a power station.

Back to my answer. There are same factors in there places: 
1. Longer Peak Sunshine Hours(PSH) than many places. PSH in Qinghai is near 5.5, and in Inner Mongolia is near 6, and in Tibet is about 7. 
2. High radiation intensity. Air mass is less than inland cities.
2. Temperature. These places are plateaus, so the daytime temperature is, even in summer, not more than 20℃.

Of course, in hotter places such as Arabic countries also suitable, for very few rainy days and long sunshine hours.
