Switching to solar power isn’t just about saving money on energy bills—it’s a practical, proven way to reduce your carbon footprint and help the UK reach its climate goals.

Key Facts: Solar and Carbon Savings

One tonne of CO₂ saved per year:

According to the Energy Saving Trust, a typical UK home solar panel system can save around one tonne of carbon dioxide (CO₂) annually. That’s about the same as driving 3,600 miles in a petrol car.
Per kWh carbon savings:

Every kilowatt-hour (kWh) of electricity generated by solar panels instead of the UK grid saves around 0.2–0.25 kg (200–250g) of CO₂. (Source: Energy Saving Trust, UK government BEIS statistics, Carbon Trust)
Long-term impact:

Over a 25-year lifespan, a standard residential solar installation could prevent 20–25 tonnes of CO₂ emissions—roughly the same as taking five petrol cars off the road for a year.
National perspective:

If every suitable UK home installed solar panels, the nation could save millions of tonnes of CO₂ each year, making a massive dent in the UK’s carbon reduction targets.

Why Solar Makes a Difference

Grid electricity still pollutes:

While the UK grid is getting greener, a significant share of electricity still comes from fossil fuels. Generating your own clean electricity directly reduces demand for polluting power.
Immediate, local impact:

Every kWh you produce and use at home means less carbon released into the atmosphere—no need to wait for government action or big infrastructure projects.
Real-life example:

A typical 4.5 kW solar system (about 10 panels, common for UK homes) can generate enough electricity to offset 80% or more of an average household’s annual usage. That’s a saving of over £30,000 on bills across 20 years and up to 1 tonne of CO₂ stopped from entering the atmosphere every year.
