Advantages and Disadvantages of Solar Garden Lights

Advantages and disadvantages of solar garden lights
1. Advantages of solar home garden lights
(1) Green and environmental protection, high safety factor, low operating power, no potential safety hazard, and can be recycled with little pollution to the environment.
(2) The light irradiated by the solar garden lamp is soft and not dazzling, without any light pollution, and no other radiation is generated.
(3) Solar garden lights have a long service life, semiconductor chips emit light, and the cumulative life can reach tens of thousands of hours, often higher than ordinary garden lights.
(4) The use efficiency is high, and the solar energy is effectively converted into light energy. Compared with ordinary lamps, the efficiency of converting heat energy into light energy is several times higher.
2. Disadvantages of solar home garden lights
(1) Instability
In order to make solar energy a continuous and stable energy source, and eventually become an alternative energy source that can compete with conventional energy sources, the problem of energy storage must be solved, that is, to store as much solar radiation energy as possible during the clear day for use at night or in rainy days, but energy storage is also weak in solar energy utilization. one of the sections.
(2) Low efficiency and high cost
Due to low efficiency and high cost, the economics are generally not competitive with conventional energy sources. For a considerable period of time in the future, the further development of solar energy utilization will be mainly restricted by economics.
