What is Solar Design Software?

Solar design software, also known as photovoltaic (PV) design software, helps engineers, architects, and solar installers plan and optimize solar energy systems by modeling the placement and performance of solar panels. It uses geographic, weather, and shading data to simulate energy production and system efficiency under various conditions. The software assists in creating detailed layouts, calculating system size, and estimating costs and return on investment. By enabling accurate design and visualization, it reduces errors and speeds up project approval and installation processes. Ultimately, solar design software helps maximize energy yield, lower costs, and support sustainable energy goals.
