Quick Answer
The UK's Smart Export Guarantee (SEG) provides export payments for eligible microgenerators. Solar PV is by far the most popular form of microgeneration in the UK, accounting for over 95% of registered microgenerators. Systems up to 3.68kW (single phase) qualify for simplified grid connection via the G98 notification process.

Microgeneration Explained
Microgeneration is the production of electricity on a small scale, usually by individual homes or small businesses, using renewable energy technologies such as solar PV, small wind turbines, or micro-hydro systems. Systems are typically under 50kW capacity and are designed primarily to meet on-site energy needs, with any surplus exported to the grid. Microgeneration helps decentralise electricity production, reduces grid strain, and lowers carbon emissions.
