Connecting a solar power plant
A solar power plant is a device that receives light energy from the sun and directly converts it into electricity using photovoltaic cells (PV cells). The power output of a power plant is referred to as peak power, which indicates how many W of electricity are generated by the plant under standard lighting conditions of 1000 W/m2 and an outdoor temperature of 25 C.
It is referred to as the Watt peak, or Wp. Individual PV cells can vary in size from 0.5 cm to approx. 4 cm. A single cell produces only 1 or 2 watts, which is not enough, so solar electricity cells must be clustered on the roof of the house. A PV cell is a specially processed slice of silicon compressed between two thin contact plates. The top contact has a positive charge and the bottom one has a negative charge, making it a semiconductor. The semiconductor absorbs photons of light and releases electrons. When free electrons are trapped, they produce electric current, which can be used as electricity.
The lifetime of a solar power plant is around 30 years. The roof pitch should be between 0 – 60. When planning the installation of a solar power plant, care must be taken to ensure that the photovoltaic modules are not shaded by roof structures, chimneys, vents, trees around the building or similar objects that could shade the surfaces. A suitable roof position for a solar power plant is SE, S or SW.
Solar power plants have many advantages. They use the sun as a source of energy. The sun’s available energy is 4000 times greater than the energy needs of today’s society. They produce energy with the highest exergy (1 kWh of electricity has higher exergy than 1 kWh of heat). Quiet operation, minimal maintenance and running costs. They provide electricity for more than 30 years without emitting any harmful substances into the environment. They represent one of the safest investments, with a predictable return. This is an investment in your own system, whose value is not only visible on the paper, but on the roof of your house. The solar power plant protects and prolongs the life of the roofing material by absorbing harmful UV radiation.
The main advantages of solar power plants are that they are clean, highly renewable and able to operate on their own or in combination with traditional energy sources.
