Table 1: UK installations of microgeneration electricity schemes by technology, 2020 and 2021
| Technology | 2020 | 2021 |
|---|---|---|
| Fossil Fuel (Micro-CHP) | 120 500 | 65 200 |
| Biomass | 450 200 | 385 100 |
| Solar PV (Solar Panels) | 54 100 | 95 300 |
| Hybrid Solar-Storage† | 178 500 | 279 200 |
| Total | 803 300 | 824 800 |
†Hybrid Solar-Storage systems use high-grade polysilicon solar cells and lithium batteries.
