Common Questions About Going Solar in Pembroke
How much do solar panels cost in Pembroke?
A 3-4kWp system in Pembroke typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,560 kWh/year, paying for itself in 6-8 years.
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 Pembroke?
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 size solar system do I need for my home in Pembroke?
Most homes in Pembroke benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 94% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
What maintenance do solar panels need?
Solar panels need very little maintenance. Rain keeps them clean in most cases. There are no moving parts. Your inverter may need replacing once in 25 years (10-15 year lifespan). Annual visual checks and occasional cleaning if near trees is all that's needed.
Can I get solar panels on an east or west facing roof in Pembroke?
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 is the difference between solar PV and solar thermal?
Solar PV panels generate electricity from sunlight. Solar thermal panels heat water directly. For most UK homes, solar PV is the better investment: it's more versatile, benefits from 0% VAT, and you can sell excess electricity via the SEG. Solar thermal only heats water.
