Wind turbine (WPP) - engineering construction that converts kinetic energy of wind into mechanical energy of rotor rotation with further conversion into electrical energy. The main types of wind turbines - horizontal impeller wind turbine and vertical carousel-type wind turbines.
What is the land area required for placement of wind plant?
For a 1 MW WPP, 30-50 ares of land will be required.
Windmills require a small area, but along the wide perimeter there should be no forest plantations and other obstacles to the wind.
Solar power plant (SPP) - engineering construction that converts solar radiation into electrical energy. Depending on the type of construction, the methods for converting the energy of solar radiation differ.
What is the land area required for placement of solar plant?
For a 1 MW SPP, a minimum of 200 ares of land will be required.
They require a larger installation area than a WPP, and there should be no objects shadowing the panels along the perimeter. It is necessary to take into account the orientation of the land plot, the best arrangement of rackings with PV panels will be on the southern slope.
Hybrid WPP/SPP systems - a wind turbine equipped with solar panels with accumulators. Mutual "insurance" of alternative energy sources is provided (the wind at night and in daytime, sun in daytime, accumulator – at any time). The controller regulates the degree of charge of the accumulators and controls the processes of system interaction.
To locate the hybrid plant, depending on the capacity, an amount of land equal to the sum, respectively, of the area for the photovoltaic panels and the area for the wind turbines will be required. The requirements for the landscape are the same: do not shadow the sun and do not obstruct the wind.
Let's compare the features of the choice of land for solar power plants (type - photovoltaic panels) with wind in the main parameters:
