Distributed PV power generation specially refers to the process that converts solar energy into electricity directly through PV modules. This often works in a system, and so it is also called distributed PV power system. This is a new style power generation method with a great prospect. This system generates electricity in nearby areas and is connected to the nearby utility grid. Also, the electricity it generates can be used at hand. It cannot only improve the generated electricity amount, but also it can effectively avoid electricity consumption when its voltage is raised or transmitted.
Today’s most widely used solar PV system is the distributed system which is installed on a rooftop. This system must be connected to the utility grid, with which it supplies electricity to nearby citizens.
Features of the system:
Firstly, its output power is relatively small. Generally speaking, a distributed PV power project’s capacity is within thousands of watts. Different from a concentrated PV power system, the size of it affects little of the electricity generating efficiency. Therefore, this affects little of its financial output. A small PV power system’s income is not necessarily lower than that of a large one.
Secondly, it doesn’t pollute the environment and is good for a personal environment and the public environment. This PV power plant doesn’t produce noise while working, nor does it do harm to air or water. Currently, environmental problems are becoming more and more prominent. Once this project is introduced and used, it will help us reduce the seriousness of environmental problems.
Thirdly, this method can also release the pressure for some areas where electricity is lacking. This system’s energy density is relatively low, for in each square meter, its power is merely 100 watts, and rooftops where solar modules can be installed are limited. Therefore, to get rid of the electricity lacking problem, this is not the perfect method although its advantages are obvious.
Fourthly, it can be used to generate and supply electricity. A large-scale ground power plant adopts the voltage-raised power transmission network but this is only a power plant. However, a distributed PV power plant adopts the power distribution network.
Where it is used:
A distributed PV solar system can be used in villages, ranches, mountains, cities, and buildings around business districts, which means it can be widely used and indeed it has been widely used to generate electricity and supply it to numerous families.
