Heat Mitigation for Photovoltaic can lower your electricity Bills

Everybody knows, when it comes to selling a product or an idea little cheats can help. So we calculate future electricity revenue a little bit more optimistic. Temperature can surprisingly be more influentially in performance and durability than previously thought.

Temperature Mitigation increases Power to Conversion Efficiency so lowers the Cost of Electricity

The radiative saving even increases with increasing temperature (which also explains the lower warming of the equator), which I did not take into account here because more research is needed.

Formel 1
Qrad = εσA(∆T4)

Asumption
ε = Space of Emission of the Roof
A    = Roof, m²
σ = Stefan-Boltzmann-Constant (5.6704 × 10 -8 W / m² ∙ K4)
ΔT = Temperature Difference between Sky adn Roof K [Kelvin = ( TºC + 273,15)]
