Solar Panel Recommendations for Paris

  • Fixed mount: Set your panels at 45.6° tilt, facing South (180° azimuth).
  • Seasonal adjustment: Tilt to 33.9° in summer and 63.9° in winter for up to 15% more annual energy.
  • Monthly adjustment: Adjust tilt each month using the table above for maximum year-round production.

Solar Potential in the Paris Region

Paris receives approximately 3-3.5 peak sun hours daily with a temperate maritime climate. The Île-de-France region's weather produces moderate temperatures, frequent cloud cover, and rainfall distributed throughout the year. Solar resource is comparable to other northern European capitals.

France's solar policies include feed-in tariffs and net metering for residential installations. The country's energy transition law (Loi de Transition Énergétique) sets targets for renewable energy growth. EDF and other providers offer purchase agreements for excess solar generation.

Paris's urban environment means many residential properties have limited roof space, and historic district preservation rules may restrict visible solar installations. However, the surrounding suburbs and newer developments offer better solar access. French solar installers are experienced in working with Paris's varied housing stock.
