You'll know it just by looking at it. It is not easy to describe it clearly using only words.
It's actually very simple: the solar cell converts solar energy into electrical energy (DC) and the inverter inverts the DC power to 50 Hz, 220 V AC alternating current to provide energy.
The diesel generator is another system. The diesel engine directly drives the alternator to produce electricity. Diesel generators are generally used as emergency power sources, that is, when the power grid fails, the diesel engine starts.
The photovoltaic system can be connected to the grid to produce electricity or used as a backup power supply.
Switching between systems is carried out via switching devices.
The concept of the number of wind turbine blades - the strength of the wind turbine. The ratio between the total surfaceof the wind turbine blades (projected in the direction of the wind) and the surface where the wind passes through the rotor (swept surface of the rotor) is called solidity (or solidity ratio, volume ratio), and constitutes reference data for wind turbines. ?
These are several types of horizontal axis wind turbines, with schematic diagrams showing four types of wind turbines: single blade, double blade, three blade and multi blade. The method of calculating solidity. of the wind turbine is as follows: S is each the projected surface of the blades in the direction of the wind, R is the radius of the wind wheel, B is the number of blades and σ is the realism ratio. σ=BS/πR2.
A wind turbine is an electrical device that converts wind energy into mechanical work, which causes the rotor to rotate and ultimately produces alternating current. Generally speaking, wind energy is also solar energy, so we can also say that wind energyne is a thermal energy generator that uses the sun as the heat source and the atmosphere as the working fluid.
