Common Questions About Going Solar in Benllech
How much do solar panels cost in Benllech?
A 3-4kWp system in Benllech typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,520 kWh/year, paying for itself in 6-8 years.
Can I get solar panels on an east or west facing roof in Benllech?
Yes. East or west-facing roofs still produce 80-85% of the output of a south-facing roof. Many installers recommend splitting panels across east and west to spread generation throughout the day, which can actually improve self-consumption.
What happens during a power cut?
Standard grid-tied solar systems shut down during a power cut for safety reasons (to protect engineers working on the grid). If you need backup power, you can install a hybrid inverter with battery storage that provides power during outages.

How does shading affect solar panels in Benllech?
Shading from trees, chimneys, or nearby buildings can reduce output significantly. Modern systems use optimisers or microinverters so that shading on one panel doesn't drag down the whole system. Your installer will assess shading during the site survey.
What roof direction is best for solar panels in Benllech?
South-facing roofs produce the most electricity (100% of potential). South-east and south-west roofs produce around 95%. East or west-facing roofs still produce 80-85%. North-facing roofs are generally not recommended for solar panels in the UK.
