## How many megawatts does a solar panel produce?

On average across the US the capacity factor of solar is 24.5%. This means that solar panels will generate 24.5% of their potential output assuming the sun shone perfectly brightly 24 hours a day. **1 megawatt (MW)** of solar panels will generate 2 146 megawatt hours (MWh) of solar energy per year.

## How do you calculate torque of a turbine?

You can always use **Power = Torque*angular velocity**. An important piece of information is that the velocity of a blade tip of a 3 blade rotor in a 12 m/s wind is about 60 m/s. This is because the tip-speed ratio equals velocity of blade tip/ velocity of wind.
