Full feed-in means that all PV electricity is fed into the public grid — ideal for investor models, ground-mounted systems, or sites without self-consumption.
Full feed-in is an operating model for photovoltaic systems in which the entire amount of electricity generated is fed into the public power grid. The system operator does not consume the generated electricity on site, but receives remuneration for every kilowatt hour fed in — for example under the Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz, EEG) or as part of a Power Purchase Agreement (PPA).
In a full feed-in model, the PV system is technically and contractually configured so that it does not supply electricity to the connected building, but feeds all generated electricity into the public grid.
The site operator continues to purchase all electricity required on site from the public grid.
This model is often chosen when there is no significant self-consumption or when feed-in remuneration is economically more attractive than using the electricity directly — for example in the case of favorable feed-in tariffs or investor-driven project models.
• Ground-mounted PV systems and solar parks without direct on-site consumption
• Roof lease models with pure feed-in operation
• Agricultural businesses with separate electricity infrastructure for buildings and generation assets
• Real estate with little or no electricity demand at the project site (e.g. vacant commercial buildings)
• Investor models focused on stable feed-in revenues (e.g. cooperatives or funds)
• Remuneration rate (ct/kWh): EEG feed-in tariff or PPA price
• Fed-in electricity volume (kWh): total annual electricity generation
• Grid connection capacity (kW): maximum electricity that can be fed into the grid
• System size: typically medium to large PV systems (from around 30 kWp upwards)
• Contract term: typically 20 years under the EEG, depending on the agreement in the case of a PPA
Full feed-in is suitable for locations without significant self-consumption or for business models focused on stable revenues from grid feed-in. It allows companies to make economic use of otherwise unused areas — for example through the sale of generated electricity or through roof leasing.
Full feed-in offers planning security, but in times of high electricity prices and increasing self-consumption optimization, it is often less economical than partial feed-in or self-consumption models.
