This graph provides an annual and monthly overview of solar power generation in France.

• The evolution of solar photovoltaic generation is an important parameter in the energy transition, as it is a renewable and low-carbon energy.
• In 2022, solar power generation rose sharply on the back of expanded capacity and good sunlight.

The data can be of various kinds:

• Data from RTE meters and distribution network operators. In order to draw up global consumption or production balances, we need to have an aggregated view of all metering data on the transmission and distribution perimeters. These data are only available on the 15th of each month for the month just ended. Although updates are possible for at least 12 months, the consolidated data is very robust from the first date of availability. Provisional data, derived from telemetry set up by network operators at various points on the power grid, supplemented by estimates for non-telemetered production or consumption. Provisional data provide an initial overview, available very quickly after each deadline; they are not of the same quality as metering data (estimates taken into account, less accurate measurement than metering data, etc.). Graph elements based on provisional data are indicated by a specific pictogram on the portal.

The graph gives an annual and monthly overview of the solar park in France.

This graph shows the average and maximum capacity factor of solar production, at monthly and annual granularity.

• Solar power plants do not always produce at maximum output. The load factor is an assessment of the producible power in relation to the installed capacity.  
• The load factor is calculated at 30-minute intervals and corresponds to the ratio of solar power output to installed capacity.

This graph shows the average and maximum coverage rate of electricity consumption by solar generation, at monthly and annual granularity.

• The solar coverage rate corresponds to the proportion of electricity consumption in France covered by photovoltaic solar power generation. It enables us to assess the evolution of solar power's share of the French energy mix. 
• The coverage rate is calculated at 30-minute intervals and corresponds to the ratio between solar production and gross consumption.
