Advantages and disadvantages of solar photovoltaic power generation

Advantages: no danger of fatigue; Safe and reliable, no noise, no pollution discharge, absolutely clean; Not limited by the geographical distribution of resources, we can take advantage of the advantages of building roofs; For example, areas without electricity and areas with complex terrain; It can generate electricity locally without consuming fuel and erecting transmission lines; High energy quality; Users are easy to accept emotionally; The construction period is short, and the time for obtaining energy is short.

Disadvantages: the production of solar panels has the characteristics of high pollution and high energy consumption, and the energy distribution density of irradiation is small, that is, the occupied area is huge; The energy obtained is related to meteorological conditions such as four seasons, day and night, sunny and rainy; At present, compared with thermal power generation, the opportunity cost of power generation is high; The manufacturing process of photovoltaic panels is not environmentally friendly.

System classification: independent photovoltaic power generation, mainly composed of solar cell module, controller and storage battery. If you want to supply power to AC load, you need to configure an AC inverter; Distributed photovoltaic power generation system is a small photovoltaic power supply system that is configured at the user site or near the power consumption site to meet the needs of specific users and support the economic operation of the existing distribution network.

Grid-connected photovoltaic power generation, centralized large-scale grid-connected photovoltaic power stations are generally state-level power stations, the main feature of which is to directly transport the generated energy to the power grid and uniformly allocate it to power users. This kind of power station has a large investment and covers a large area, so it has not developed much. Decentralized small grid-connected photovoltaic has become the mainstream of grid-connected photovoltaic power generation because of its advantages of small investment, fast construction, small area and strong policy support.
