The easiest way to draw electrical diagrams for photovoltaic installations is by using the EasySolar app, where such diagrams, including all necessary components, can be automatically generated. A photovoltaic (PV) installation consists of several key components that must be correctly represented on the electrical diagram.
Provide an architectural drawing and riser diagram for the homeowner showing the planned location for future photovoltaic and solar hot water system components. Space requirements and layout for photovoltaic and solar water heating system components should be taken into account early in the design process.
There are several ways to create your own solar panel wiring diagram — you can draw it out on paper, print out an existing diagram and mock it up with a pen to fit your liking, or design it from scratch digitally.
A solar panel wiring diagram (also known as a solar panel schematic) is a technical sketch detailing what equipment you need for a solar system as well as how everything should connect together. There’s no such thing as a single correct diagram — several wiring configurations can produce the same result.
ProfiCAD supports the drawing of photovoltaic circuit diagrams. In addition to the common electrical engineering symbols, the library includes symbols such as solar cells, photovoltaic panels, solar collectors, inverters, etc. Should you need more symbols, you can create them in the symbol editor. Some sample drawings (click for full size):
Configure your system layout, taking into account factors such as panel orientation, spacing, and wiring topology. Plan the wiring and connections between your solar panels, inverters, MLPEs, and other system components. Design the electrical circuitry to minimize losses, optimize performance, and ensure safety.
