Solar photovoltaic systems convert sunlight directly into electricity using semiconductor cells, enabling homes and businesses to generate their own renewable power.
Solar photovoltaic (PV) technology converts sunlight directly into electricity using the photovoltaic effect. Unlike solar thermal systems that heat water, solar PV generates electrical current that can power appliances, be stored in batteries, or exported to the grid.
| Component | Function |
|---|---|
| PV Panels | Convert light to DC electricity |
| Inverter | Convert DC to AC |
| Mounting System | Secure panels to roof/ground |
| Isolators | Safety disconnection points |
| Generation Meter | Measure output for incentives |
| Battery (optional) | Store excess generation |

We support solar installers with:
Microgeneration Certification Scheme certification is required for installers to provide renewable energy systems that qualify for government incentives and feed-in tariffs.
The Smart Export Guarantee requires licensed electricity suppliers to offer payment for exported renewable electricity from small-scale generators like solar PV.
G98 is the DNO notification process for small-scale generation systems up to 16A per phase (3.68kW single-phase), allowing 'fit and inform' installation without pre-approval.
G99 is the engineering recommendation governing the connection of generation equipment to distribution networks, requiring DNO approval for systems over 16A per phase.
Battery energy storage systems store electricity for later use, commonly paired with solar PV to maximise self-consumption and provide backup power.
