Solar PV & Renewable Energy Symbols — UK

These symbols appear on solar PV system drawings, MCS certificates, and electrical installation diagrams for renewable energy systems in the UK. They follow BS 7671 Section 712 (Solar photovoltaic systems) and Section 722 (Electric vehicle charging). Solar installers, MCS-certified engineers, and electricians use these on design and commissioning documentation.

Frequently asked questions about solar & renewables symbols

What symbols are needed on a solar PV installation drawing?
At minimum: PV array layout, string configuration, DC isolator positions, inverter location, AC isolator, generation meter, and connection to the consumer unit. The drawing should also show the earthing arrangement.
What is MCS certification?
MCS (Microgeneration Certification Scheme) is the quality assurance scheme for small-scale renewable energy installations in the UK. MCS certification is required for Feed-in Tariff (FiT) and Smart Export Guarantee (SEG) payments.
Do EV charger installations need specific symbols?
Yes. BS 7671 Section 722 covers EV charging installations. The installation drawing should show the charge point location, dedicated circuit, earthing arrangement, and any load management equipment.
