Ash solar panel questions answered
How much do solar panels cost in Ash?
A 3-4kWp system in Ash typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,900 kWh/year, paying for itself in 6-8 years.
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.
How long do solar panels last?
Modern solar panels are warrantied for 25-30 years and typically last even longer. Panel efficiency degrades by about 0.5% per year, so after 25 years, your panels will still produce around 87% of their original output. Inverters typically last 10-15 years and may need one replacement.
What roof direction is best for solar panels in Ash?
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.
What size solar system do I need for my home in Ash?
Most homes in Ash benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 103% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
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.
Do solar panels work in winter in Surrey?
Yes, solar panels generate electricity all year round. While output is lower in winter, Surrey still receives usable daylight hours even in December. Annual generation figures (3,900 kWh for a 4kWp system) already account for seasonal variation.
