Economical and affordable: Solar lamps do not require external power supply and do not require payment of electricity bills. Although the cost of purchasing solar lamps is relatively high, long-term use can save a lot of electricity expenses.

Long lifespan: Solar lamps have a longer lifespan and can generally be used for more than 10 years. The lifespan of solar panels is usually over 20 years, while the lifespan of lamps can also reach around 10 years.


Mobility: Solar lamps can be moved according to demand without being limited by power supply. This makes solar lights very convenient to use in outdoor activities, camping, and other occasions.


Solar lamps also have the following disadvantages:


Unstability: The solar Irradiance received on the earth's surface is intermittent and does not meet the requirements of stability, so the solar lamp sometimes suffers from power shortage. To improve the conversion rate, expensive equipment is often required, which increases the project cost.


Low efficiency and high cost: Although the use of solar energy technology is becoming increasingly mature, some solar energy conversion devices have low efficiency and high cost, and overall, their cost-effectiveness is relatively low.
