A solar collector is a device that converts the sun's radiant energy into thermal energy. Since solar energy is relatively dispersed and must be concentrated somehow, collectors are a key part of various devices that utilize solar energy. Due to their different uses, there are many types of collectors and their matching system types, with different names.
The solar PV systems consist of a solar cell set, solar controller, and battery (set). An inverter is also required if the output power is 220V AC or 110V.
Solar water heating project mainly consists of a solar collector, heat storage system, control system, heat exchange system, auxiliary energy system, thermal insulation material, piping system, accessories, etc.
