It is used by solar installers, engineers, designers, project developers, and sales teams that need to create accurate site plans and proposals before installation begins. For buyers comparing the best solar design software, the category typically focuses on tools that support system layout, energy production estimates, shading analysis, and equipment selection.

Common features include 2D and 3D roof modeling, panel placement, string sizing, irradiance calculations, and financial or performance simulations. Many top solar design tools also generate proposal documents, bill of materials, and permit-ready drawings to streamline project handoff. By improving design accuracy and speeding up quoting and planning, this software helps teams reduce manual work, support clearer customer presentations, and move projects through the sales and delivery process more efficiently.
