What It Means For Homeowners

Cut your electricity bill by up to £200 per year

A small plug-in solar setup can help offset everyday daytime electricity use, reducing reliance on grid energy.

☀️

600–800 kWh/year

Estimated annual generation for an 800W solar setup in typical UK conditions.

💷

£150–£200/year

Estimated annual value based on electricity at around 25–30p per kWh.

🏡

Best used in the day

Great for appliances, home offices, standby loads, refrigeration and everyday background usage.

Simple example

If the system generates around 600 kWh per year and that energy is used in the home, that is roughly £150 per year of electricity value at 25p/kWh.

600 × £0.25 = £150

Assumes generated electricity is consumed on-site.

Savings are estimates only and will vary depending on location, orientation, shading, installation conditions, electricity tariff and how much generated electricity is used within the property.
