Umbrellas and sunshades are used for windproofing, rainproofing, and sun protection, and are used outdoors. In some open-air cafes, restaurants, and other places, large umbrellas are often used. Since these umbrellas are used outdoors, they are exposed to sunlight most of the time. Therefore, apart from their basic functions, umbrellas can actually be a very good tool for utilizing solar energy. The solar umbrella light is one such application. During the day, the umbrella can absorb sunlight, and at night, it can use the solar energy absorbed during the day to light up the umbrella light for illumination, eliminating the need for additional electricity. It is currently priced at 45 pounds in foreign markets.
