It is better to purchase finished products, because the solar lights that meet your needs can be purchased directly, which is more convenient and avoids possible assembly errors by yourself.
Outdoor solar lights use sunlight as energy. During the day, the battery is charged via the solar panel. At night, the battery converts the energy into light energy to obtain lighting. green, eco-friendly and sustainable.
Solar Panels: There are three types of solar panels used for solar lighting in the market: monocrystalline silicon solar panels, polycrystalline silicon solar panels, and amorphous silicon solar panels. The conversion rate of monocrystalline silicon panels is higher, between 15 and 21%, followed by polycrystalline silicon panels, which can reach 16%. The cost is also lowerr to that of monocrystalline silicon panels, so they are used by most lighting manufacturers.
Actually, this rechargeable solar light is not expensive, because the rechargeable solar light also uses the light and power of the sun to generate electricity, but when the sun is average, it will it rains, she will. I can't generate electricity, so I don't really recommend buying solar electricity, but this solar light is indeed very energy efficient.
It depends on your own needs, generally 50 equals 500. There is both good and bad
