Solar Panel FAQs for Larne
How much do solar panels cost in Larne?
A 3-4kWp system in Larne typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,240 kWh/year, paying for itself in 6-8 years.
Do I need a smart meter for solar panels?
You need a smart meter to sell surplus electricity back to the grid under the Smart Export Guarantee (SEG). Your energy supplier will install a smart meter for free. Your installer submits the G98/G99 application to your DNO after installation.
What roof direction is best for solar panels in Larne?
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 Smart Export Guarantee (SEG)?
The Smart Export Guarantee (SEG) requires licensed energy suppliers to offer a tariff to small-scale generators for electricity exported to the grid. Rates are typically 3-15p/kWh. You need a smart meter and an MCS-certified installation to be eligible.
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 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.
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.
