Solar panels convert sunlight into electricity, reducing your energy bills and generating income through the Smart Export Guarantee.
Solar panels use photovoltaic cells to convert sunlight into electricity. This powers your home during the day and feeds excess energy back to the grid.
The Smart Export Guarantee (SEG) pays you for excess solar electricity you export to the grid. Choose from multiple suppliers to get the best rate.
MCS certification is the UK's quality standard for renewable energy installations. Only MCS installers qualify for government schemes and SEG payments.
Solar batteries store excess energy for use when the sun isn't shining. This increases your self-sufficiency and maximises savings from solar generation.
Solar panel prices have stabilised after years of decline. A typical 4kW system suitable for an average UK home costs £6,000-£8,000 including installation. Read our complete guide to solar panel costs for detailed breakdowns.
