Most solar Christmas lights have a low-quality collector that darkens and becomes cloudy over time due to exposure to the sun and rain, resulting in it not being able to absorb radiation as effectively. The purpose of the collector is to charge a rechargeable AA battery located inside the collector box. This single battery is responsible for powering the LED lights. It goes without saying that the more lights there are, the fewer hours they will illuminate. So don't be surprised when you are about to purchase a set with many lights.

In conclusion, depending on the cost of purchase and the potential energy savings, solar lights are useful for outdoor spaces in cases where we cannot use electricity because there is no outlet in the garden.
