After twenty years of operation, many agricultural PV systems are reaching the end of their EEG feed-in support. Yet old modules need not become waste. This presentation shows how decommissioned modules can be dismantled, recycled and documented with a certificate of proper disposal. Using a shot-blasting process, in which the junction box and frame are removed mechanically and the glass is separated from the electrical core, we explain how modules can be recovered as close to full value as possible. The session then turns to the future of existing sites: intelligent energy management and storage technology make it possible to control self-consumption and grid feed-in in a targeted way. An impulse for energy farmers who want to rethink their installations.
