CHARACTERISTICS
Solar photovoltaic power generation is a way of power generation that directly
transforms solar energy into electric energy.As a clean and renewable energy,solar enerfy has become the focus of attention due to its unique advantages.The application of solar energy is an inevitable choice for human begings.
Solar power generation without movng parts,not easy to damage,simple mainteance,especially suitable for attended use.It can make full use of the idle roof,and creat economic value.After the roof is installed with solar panels,it can effectively prevent the direct sunlight on the roof,indirectly protect the roof,and also take the role of heat insulation.
