How Solar Reduces Your Bill
Independently written
How much do solar panels reduce your bill?
Solar panels reduce UK electricity bills by 50-85% by replacing expensive grid electricity (24.5p/kWh) with free solar. A 4kW system on a home paying £1,300/year reduces to: £600-800 without battery (50% reduction), £400-600 with battery (60-70%), £200-400 with battery + smart tariff (75-85%). You still pay the standing charge (~£365/year). The reduction appears on your bill as lower kWh imports.
