system compositionSolar panel: It is the core component of a home solar system, consisting of multiple solar cells connected in series or parallel. Commonly used solar cells include monocrystalline silicon, polycrystalline silicon, and thin-film solar cells. Its function is to convert solar energy into direct current electricity.Inverter: As solar panels generate direct current, and household electricity is usually alternating current, an inverter is needed to convert direct current into alternating current for household appliances to use.Energy storage battery: used to store the excess electricity generated by solar panels when there is sufficient sunlight, for use at night or on rainy days when there is insufficient sunlight, ensuring the continuity and stability of household electricity consumption.Controller: Its main function is to regulate and control the electrical energy output from the solar panel, prevent overcharging and overdischarging of the battery, and protect the saf...
