Your solar questions for Narberth
How much do solar panels cost in Narberth?
A 3-4kWp system in Narberth typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,560 kWh/year, paying for itself in 6-8 years.
Do I need to clean my solar panels?
In most cases, rain keeps solar panels clean enough in the UK. If your panels are near trees or at a low angle, an annual clean may improve output by 2-5%. Never use abrasive materials. A soft brush and water is sufficient.
What happens to my solar panels if I move house in Narberth?
Solar panels stay with the property as a permanent fixture. They add value to your home for the next buyer. Your installer can transfer monitoring accounts to the new owner.
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 add a battery to my solar system?
Yes. A home battery (typically 5-10 kWh) stores excess solar electricity for evening use. This increases your self-consumption from around 30-40% to 60-80%. Batteries currently cost £3,000-£6,000 and also benefit from 0% VAT.
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.
What size solar system do I need for my home in Narberth?
Most homes in Narberth 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.
