Solar PV
Solar photovoltaic panels generate free electricity from daylight — reduce your bills, earn export payments via the Smart Export Guarantee, and qualify for 0% VAT.
Step by step
How Solar PV installation works
-
A roof and shading survey determines the optimal panel layout and system size.
-
MCS-certified installers fit panels, mounting rails, wiring, and an inverter — typically in one day.
-
A generation meter is installed; your installer registers the system with your electricity network operator.
-
You receive an MCS certificate, enabling you to register for Smart Export Guarantee payments from your energy supplier.
