Propflare is a prospecting platform for solar PV installers and solar panel cleaning and maintenance companies in France. You draw your area on the map: Propflare analyses every house (roof size and orientation, yearly sunshine, existing panels) and rates each roof from A+ to C. For each selected house it prepares a personalised 6-page solar study under your brand (recommended system size, panel layout on the real roof photo, monthly production, savings and payback), sent by post or downloaded as a PDF. Each letter carries a personal code and a QR code: the household views its study online and asks to be called back. One first letter per household, opt-out list honoured, mandatory French legal mentions on every letter. Interface, studies and letters are in French.
