Save with solar

see how much you could save.
*Solar panels and savings are subject to eligibility requirement, geographical restrictions and terms and conditions. These are example figures only and are based on standard MCS calculations for a south-facing 12-panel solar array in central England, on a 35-degree tilt roof, with no shading, and annual electricity usage of 4,000 kWh. The tariff rate is 25.73p/kWh (Ofgem Energy Price Cap from 1st July 2025). Savings assume a 5.1 kWh battery and Smart Export Guarantee (SEG) payments of 21p/kWh under the E.ON Next Premium v2 Export tariff. Actual savings may vary. Our experts may suggest additional or alternative products, updating savings based on your specific situation. Geographical and eligibility restrictions apply.
