We recommend getting at least three quotes from MCS-certified installers to compare pricing and equipment.

With a cost of £6,600-£8,500 (0% VAT included) and savings of £589+ per year based on Aberffraw's solar yield of 827 kWh/kWp at current electricity rates of around 25p/kWh, plus Smart Export Guarantee income of around 13-15p/kWh for surplus electricity, a typical solar system in Aberffraw pays for itself in 11-13 years. Anglesey ranks #50 of 102 UK counties for solar yield, above the national average. After payback, you benefit from 12-19 years of near-free electricity as panels last 25-30 years. Adding a battery extends self-consumption and can reduce payback further if you use most electricity in the evenings. Total lifetime savings typically reach £15,000-£18,000 depending on your usage pattern.

In most cases, regular UK rainfall keeps solar panels clean enough to perform well. If your panels are near trees, under bird flight paths, or at a low pitch angle (below 15°), an annual clean may improve output by 2-5%. Never use abrasive materials, pressure washers, or household cleaning products, a soft brush and clean water is sufficient. Professional panel cleaning services typically cost £50-£100 per visit. Your panels have no moving parts and require very little maintenance over their 25-30 year lifespan.

An Energy Performance Certificate (EPC) rates your home's energy efficiency from A (most efficient) to G (least efficient). While an EPC is not required for solar panel installation, adding solar panels typically improves your rating by 1-2 grades, which can increase your property value by up to 4%. An EPC assessment costs around £60-£120 and is valid for 10 years. If you are selling or renting your property, an up-to-date EPC is legally required, so having solar panels reflected in your rating is beneficial.

Yes. Solar panels improve your EPC rating by 1-2 grades and can increase property value by up to 4% according to recent UK property market research. Buyers increasingly look for energy-efficient homes with lower running costs, particularly as electricity prices remain high at around 25p/kWh. A solar system in Aberffraw generating 3,308 kWh/yr is a long-term investment in your property that also generates income through the Smart Export Guarantee. With a 25-30 year panel lifespan, future buyers inherit decades of remaining electricity savings.

A smart meter is required to sell surplus electricity back to the grid under the Smart Export Guarantee (SEG) and earn around 13-15p/kWh for your exports. Your energy supplier will install a smart meter for free if you do not already have one, contact them before or shortly after your solar installation. You do not strictly need a smart meter for the solar panels themselves to work, but without one you cannot receive SEG payments. Your MCS-certified installer submits the G98/G99 application to your Distribution Network Operator after installation to register your system for grid export.

Based on PVGIS satellite data for Aberffraw's coordinates, a 4kWp system generates approximately 3,308 kWh per year at a yield of 827 kWh/kWp, covering 87% of average household use (3,800 kWh/year). The area receives around 1,490 sunshine hours annually. Anglesey ranks #50 of 102 UK counties for solar yield, above the national average. Output peaks between May and August and is lower in winter, though annual generation figures already account for this seasonal variation. South-facing roofs at a 30-40° pitch achieve optimal yields, while east or west-facing roofs still produce 80-85% of maximum output.
