The next five years on our calibrated price model, in a low, a base and a high scenario: the median and the conservative figure of each year, and the NPV and IRR on your own size and capex.
Indicative figures only
They come from simplified models: past prices, an asset as its datasheet describes it, and a battery that knows the next day's prices when it plans a day. Before any fee, tax, grid tariff or wear of the battery. They are neither a forecast, an offer nor investment advice.
How it is computed
- Prices: the day-ahead auction of the French bidding zone, published by ENTSO-E, hourly until 30 September 2025 and by the quarter-hour since. The figures run to yesterday and are updated every morning.
- Solar: 1 MWp of panels at the best inclination, 14 % of losses, hour by hour from PVGIS (European Commission), each quarter-hour's output sold at its price.
- PVGIS has no weather year after 2023: from 2024 on, the output is the site's average year over 2005–2023. Over 2017–2023, the average year's revenue here was -4.4% to +3.9% relative to the real year's.
- The past only: what the market may do next takes a price model, which an account shows on these same assets.
