Rooftop solar power plants (located on flat, pitched and other types of roofs).We will only touch on those solar power plants based on the principle of direct photovoltaic conversion of solar radiation energy into electrical energy, and we will not discuss other technologies such as concentrator solar power plants (tower, dish, parabolic, based on the Stirling engine), thermal solar collectors and many other.Īccording to the method of placing solar modules, all photovoltaic systems are divided into the following types: In this article, we will briefly review the most popular types of solar power plants (photovoltaic systems) and offer our own version of their classification. The solutions that are being deployed and operated to generate clean solar electricity come in many configurations and differences. Solar energy technologies are constantly evolving and improving. Moreover, the share of large commercial PV systems accounted for about 89% of this capacity. So, at the beginning of 2021, almost 7 GW of solar power plants were installed throughout the territory of Ukraine. The policy of state support over the past 10 years has made it possible to launch the photovoltaic industry in Ukraine and reach large volumes in terms of the total installed capacity. (August 4, 2015).The rapid development of solar energy throughout the world has provoked great interest in this area in our country. ↑ 6.0 6.1 Brain, Marshall, and Dave Roos.Wolfson, "Electricity" in Energy, Environment, and Climate, 2nd ed., New York, NY: W.W. The corresponding power loss in the lines decreases by the square of the current, meaning that if the current dropped by a factor of 2, the power loss drops by a factor of 4. This problem is essentially solved (not completely, but to an acceptable level) by the use of high voltage power lines. The reason that step-up transformers are used is because when travelling long distances through a conducting wire, electricity will inevitably lose energy to resistance. This electricity can flow long distances, with a typical maximum distance being around 500 kilometers. This increase in voltage is accomplished by a transformer. This means that the voltage is increased, with a proportional decrease in the electric current (the amount of electrons that are flowing per second). Electricity exiting the power plant passes through a transmission station where the electricity is "stepped-up". main articleĮlectrical transmission is accomplished by the use of power lines. Large high voltage power lines are a crucial component to the grid as they transport electricity with little energy losses. These plants generate lots of electricity and are often far away from the demand for electricity the next system (transmission) solves this problem.įigure 1. Power plants require the energy from fuels such as coal or natural gas, or primary energy flows, such as wind and sunlight in order to do this. The grid consists of countless complex interconnections, however there are three main sections- electricity generation, transmission and distribution.Įlectricity begins in power plants which work to convert mechanical energy of a turbine into electrical energy by the use of a generator (with the exception of solar power, which uses photovoltaic cells to accomplish this). These systems have grown from small local designs, to stretching thousands of kilometers and connecting millions of homes and businesses today. The electrical grid is the intricate system designed to provide electricity all the way from its generation to the customers that use it for their daily needs.
