Some components of photovoltaic power plant equipment are blocked by various factors, such as trees, dust, buildings, etc. Some of the blocked components can easily cause hot spot effects and affect the power generation of the power plant. According to estimates, dust losses in power plants could reach 6%! According to the circuit principle, when components are connected in series, the current is determined by the smallest component. Therefore, if there is a shadow on a component, it will affect the power output of that component. Therefore, components should be cleaned and wiped regularly to reduce dust. Line losses are mainly line losses in the DC and AC circuits of the system. To use wires with good electrical conductivity, the wires must have sufficient diameter. No shortcuts arepermitted in construction. When maintaining the system, special attention should be paid to the connection of plug-ins and the safety of wiring terminals.
Causing serious and irreversible damage to solar cells. For photovoltaic solar cells, when the climatic pressure exceeds its allowable stress limit, static and dynamic loads change the stress distribution in the solar cell, causing serious and irreversible damage to the solar cell. Photovoltaic solar cells (photovoltaic cells for short) are used to directly convert light energy from the sun into electrical energy. This battery uses a large number of silicon-based solar cells, which can be divided into monocrystalline silicon, polycrystalline silicon and amorphous silicon. solar cells.
