Potentielsolaire

About

Founded in 2026, Potentielsolaire is a private headquartered in France specializing in Solar.

Potentielsolaire is a solar energy advisory platform specializing in residential photovoltaic installations in France. The core offering is an independent, free simulator that combines satellite analysis (Google Solar API) with European Commission solar radiation data (PVGIS) to provide homeowners with accurate production estimates (±10%), installation pricing after deducting state incentives, and 20-year financial projections. The simulator integrates France's current subsidy landscape: self-consumption premiums (€80–140/kWc depending on capacity), EDF OA buyback tariffs (guaranteed 20 years), reduced VAT (5.5% for qualifying installations), and income tax treatment. The platform covers mainland France and Corsica, accounting for regional solar variation (north-south differences of ~30% irradiance). Beyond simulation, Potentielsolaire publishes detailed educational content on panel technology (400–500W standards), system sizing, autoconsumption optimization, battery storage ROI, and common installation pitfalls. It positions the simulator as differentiated from generic cadastral tools by translating technical data into actionable consumer guidance: real costs, verified savings ranges (€800–€1,800/year for 6kWc depending on region), and RGE installer vetting.
