When solar panels are illuminated by light, they can convert light energy into electrical energy, causing current to flow from one side to the other. Solar panels are designed based on this principle. As long as the solar panel is illuminated by sunlight or light, it can generally emit electricity equivalent to 1/10 of the light energy received. In order to minimize light reflection and convert light energy into electrical energy, a solar panel is usually covered with a film to prevent light reflection, making the surface of the solar panel purple. Not so long ago, scientists managed to develop an efficient solar panel. It not only provides electricity during the day, but also electricity at night!
1. Advantages of Rooftop Solar Panels 1. If the solar panel is installed on the roof, it can use effefficiently use solar resources to produce electricity and save energy. power. Currently, the state provides subsidies for the installation of electricity generation panels. Approved solar power generation will reduce our daily electricity consumption, meaning your family will save on their electricity bills. 2. Disadvantages of Rooftop Solar Panels 1. The investment in installing solar panels is relatively large and for some families, installation costs can be factored in. Questions will not be accepted. 2. This type of solar power generation panel is installed directly on the roof. It will be affected for a long time afterward. When exposed to sun and wind, corrosion problems can occur. 3. After all, solar panels are obtained from solar energy. It also uses resourcesthese of Yang to produce electricity, so it can only produce electricity on sunny days. Use it, but if it is cloudy or not very sunny. Sometimes power consumption is affected.
