Frequently Asked Questions About Solar Panels in Kettering
How much do solar panels cost in Kettering?
A 3-4kWp system in Kettering typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,700 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.
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.
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 does shading affect solar panels in Kettering?
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.

Yes. With estimated savings of £1039+ per year, 0% VAT, and export income of 3-15p/kWh through the Smart Export Guarantee (SEG), a solar system in Kettering pays for itself in 6-8 years and lasts 25+ 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.
