Your solar questions for Towcester
How much do solar panels cost in Towcester?
A 3-4kWp system in Towcester typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,700 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.
How do I get the best deal on solar panels in Towcester?
Get at least 3 quotes from MCS-certified installers. Check they are registered with MCS at mcscertified.com. Compare pricing, equipment brands, and warranties. Ensure your installer handles the DNO notification (G98/G99 application).
What size solar system do I need for my home in Towcester?
Most homes in Towcester benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 98% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
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 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.
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.
