Frequently Asked Questions About Solar Panels in Lowestoft
How much do solar panels cost in Lowestoft?
A 3-4kWp system in Lowestoft typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,880 kWh/year, paying for itself in 6-8 years.
What is an EPC assessment and do I need one?
An Energy Performance Certificate (EPC) assessment rates your home's energy efficiency from A to G. While not required for solar installation, solar panels typically improve your EPC by 1-2 grades, which can increase your property value. An EPC costs around £60-£120.
What roof direction is best for solar panels in Lowestoft?
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 is the payback period for solar panels in Lowestoft?
With a cost of £5,000-£8,000 (0% VAT) and savings of £1092+ per year plus SEG export income, a typical solar system in Lowestoft pays for itself in 6-8 years. After payback, you get 20+ years of near-free electricity.
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 sell excess solar electricity?
Yes. Under the UK's Smart Export Guarantee (SEG), you can sell surplus electricity at 3-15p/kWh. You need a smart meter and an MCS-certified installation. Your energy supplier pays you for every unit exported to the grid.
Do I need planning permission for solar panels?
Most residential solar installations in the UK are permitted development and don't require planning permission, provided panels don't project more than 200mm from the roof surface. Listed buildings and conservation areas may have additional requirements.
