Problems solved by technology
Due to the high dependence on sunlight intensity and time, at present, my country's photovoltaic lighting system is mainly used in street lighting projects in areas with high sunlight intensity and abundant solar energy resources, as well as lighting projects in environmentally friendly and energy-saving areas. In coastal areas with poor sunshine conditions There are few applications due to the inability to maintain system stability, and these areas have a relatively developed economy, high population density, and high power consumption for lighting systems, which imposes a heavy burden on the power grid
