Solar decorative lights use the volt effect principle of solar cells. During the day, the solar cells absorb solar photon energy, charge the battery pack through the controller, and provide power to the DC lamp load at night. The DC controller can ensure that the battery will not be damaged due to overcharging or over-discharge in sunny or long-term rainy weather. It also has functions such as light control, sound control, temperature compensation, lightning protection, and reverse polarity protection.

The daily use of solar lamps usually has the following characteristics:

1. Independent installation, no need for embedding, backfilling, saving construction costs.
2. The solar lamps are automatically controlled and do not require personnel management, saving management expenses.
3. No electricity is used, saving electricity operating costs.
4. Simple maintenance, safe use, and no electric shock accidents.
5. Solar lamps are environmentally friendly, pollution-free, and radiation-free.
6. The DC voltage used is 12V~36V, which is very safe and will not cause electric shock or fire. The installation is simple, there will be no concerns about power outages and power cuts, and it can be used in places without electricity.
7. Long service life, strong light effect, using high-efficiency energy-saving light source, long-term durability.
