Description

New photovoltaic power station

technical field

The utility model relates to the field of photovoltaic technology, in particular to a novel photovoltaic power station.

Background technique

Photovoltaic power generation is mainly a technology that uses the photovoltaic effect of the semiconductor interface to convert light energy into electrical energy, and at the same time stores the electrical energy in the battery, and transmits the electricity to the grid through the inverter. Photovoltaic power generation has the characteristics of clean and environmental protection, and is currently the most encouraged green power development energy project by the state.

At present, photovoltaic power plants are generally built in remote areas far from towns, and staff regularly perform post-maintenance maintenance. However, due to the limitation of the natural environment, it is difficult for the staff to take good care of the photovoltaic power plants in each area, and after the photovoltaic power plants are constructed, there are many follow-up problems that cannot be solved in time. Taking hilly areas as an example, the soil on the hillside is relatively loose, and the photovoltaic power station built on this geology may be at risk of being overturned in extreme weather. In addition, in hot summer, the sunshine intensity is high, the outdoor temperature is high, and the excessively high temperature on the photovoltaic modules will cause the "hot spot effect" to cause the loss of power generation of the photovoltaic system. Not only that, there are overgrown grasses near photovoltaic power stations in hilly areas, and fire prevention work in summer and winter is also urgent.
