This is an illustration of a circuit schematic for cooling solar panels with nanofluids. It uses a circuit schematic to demonstrate solar panel cooling using phase change material and nanofluids. A circuit diagram is a demonstration of an electrical circuit that employs either simple representations of parts or industry standard symbols. The use of symbols is decided by the audience. The two usually used forms of circuit diagrams are known as pictorial (using simple graphics) and schematic style (using industry standard symbols). No matter which form you want to make, it can be made in a variety of ways. Although they can be generated manually, creating one online is a more efficient method. Using diagramming software such as EdrawMax that is specifically designed for creating a circuit diagram offers several advantages.
