OpenSolar helps solar installers and sales teams win jobs. A user enters an address, and the software pulls satellite imagery and builds a 3D model of the roof, where panels can be placed and shading analyzed. It estimates energy production and savings, then generates a proposal customers can view online and sign.
The platform includes tools for the whole sales process. A customer relationship manager tracks leads, a pricing engine builds quotes, and integrated financing lets homeowners compare loan or lease options. AI features automate roof detection and layout, which speeds up design for each prospect, and electrical design tools help with permit packages.
The core software is free for installers, with revenue from financing, hardware ordering, and paid add-ons. Estimates depend on data quality and local rules, and site visits still matter. Alternatives include Aurora Solar, HelioScope, Solargraf, Sunrun’s tools, and PVsyst for engineering. OpenSolar suits solar installers who want design and sales tools at low cost.
