caption: The image shows a black and white drawing of a solar panel with a grid pattern, which is a type of solar cell used to generate electricity. The grid pattern is composed of small, evenly spaced cells that are connected to each other by a thin metal frame. The cells are arranged in a symmetrical pattern, with the largest cell at the bottom and the smallest at the top. The solar panel is surrounded by a halo of light, indicating that it is powered by electricity.
