Clean power maths: solar yield, wind turbines, capacity factor, batteries and LCOE
Annual energy from a solar array's area, efficiency and sunlight.
Power a wind turbine extracts, rising with the cube of wind speed.
Maximum fraction of wind energy any turbine can capture.
Ratio of actual output to theoretical maximum.
Lifetime cost per unit of energy produced.
Energy stored from voltage and charge capacity.
How long a battery powers a load given depth of discharge.
Years to recover a solar install from annual savings.
Fixed panels roughly tilted to the site latitude capture the most annual energy.
Fraction of DC power converted to usable AC.
Power from falling water: flow rate times head.
Carbon saved by generating clean energy instead of fossil power.
Sunlight power hitting a tilted surface.
Panel power after n years of gradual degradation.
Area swept by turbine blades, which sets its power potential.
