Ensure your renewable energy contractor meets the rigorous technical standards established by British regulatory authorities:
For UK roofs with chimney shadows, dormers, or adjacent trees, module-level power electronics (like Enphase IQ8 or SolarEdge optimizers) prevent a single shaded panel from throttling the entire string.
Systems with inverters up to 3.68kW per phase must be notified under ENA G98 within 28 days of commissioning. Larger systems require prior G99 network permission from the regional Distribution Network Operator.
The fundamental benchmark for UK renewable installations. MCS certification is legally required to claim the UK Government 0% VAT relief and register for the Smart Export Guarantee (SEG) with energy suppliers.
