Background technique

Solar photovoltaic power generation mainly absorbs solar energy through photovoltaic modules, and then directly converts solar energy into electrical energy. Photovoltaic modules (also called solar panels) are the core components of solar photovoltaic power generation, which mainly include laminates and frames.
