Problems solved by technology

The disadvantages of the photovoltaic power station built in the above two ways are: the structure and installation of the photovoltaic power station consume more and more related materials such as AC and DC cables and connectors, and the power generation loss and safety hazards of the power station system are relatively large. More losses or lower output efficiency of grid-connected power generation, higher construction costs
