The equation used to calculate wind turbine power is: Power (W) = 0. 5 × ϱ × πr² × Cp × CF × v³ where ϱ is wind density in kg/m³, πr² is the swept area of the turbine, Cp is the power coefficient, CF is the capacity factor and v is the velocity of the wind in m/s.

The power available in the wind is calculated by the formula: P = 0. 5 × ρ × A × V³. ρ (Rho): Air density (approx 1. A (Area): The swept area of the blades (π × r²). A larger rotor captures significantly more energy.

In real-world conditions, solar panels typically operate 20-40°C above ambient air temperature, meaning a 30°C (86°F) day can result in panel temperatures reaching 50-70°C (122-158°F).
