What Thurso homeowners ask about solar
How much do solar panels cost in Thurso?
A 3-4kWp system in Thurso typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,080 kWh/year, paying for itself in 6-8 years.
What roof direction is best for solar panels in Thurso?
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 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.
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.
Can I get solar panels on an east or west facing roof in Thurso?
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.
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.
How does shading affect solar panels in Thurso?
Shading from trees, chimneys, or nearby buildings can reduce output significantly. Modern systems use optimisers or microinverters so that shading on one panel doesn't drag down the whole system. Your installer will assess shading during the site survey.
