Frequently Asked Questions About Solar Panels in Freshwater
How much do solar panels cost in Freshwater?
A 3-4kWp system in Freshwater typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 4,280 kWh/year, paying for itself in 6-8 years.
Do solar panels work in winter in Isle of Wight?
Yes, solar panels generate electricity all year round. While output is lower in winter, Isle of Wight still receives usable daylight hours even in December. Annual generation figures (4,280 kWh for a 4kWp system) already account for seasonal variation.
What roof direction is best for solar panels in Freshwater?
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.
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 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 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.
Can I get solar panels on an east or west facing roof in Freshwater?
Yes. East or west-facing roofs still produce 80-85% of the output of a south-facing roof. Many installers recommend splitting panels across east and west to spread generation throughout the day, which can actually improve self-consumption.
