Solar Savings Calculator

Estimate your potential solar savings in seconds

How Much Could You Save with Solar?

Use our solar savings calculator to get an instant estimate of how much you could save with a solar PV system at your Manchester home. Simply enter a few details about your property and energy usage, and we'll calculate your potential savings, system size, and payback period.

Please note that this calculator provides estimates only based on typical Manchester conditions. For a precise quotation tailored to your specific property, please request a free site survey by calling 0330 223 7664 or completing our contact form.

How Our Calculator Works

The calculator uses your annual electricity bill to estimate your consumption, then determines an appropriately-sized solar PV system for your property. Generation estimates assume typical south-facing or south-east/south-west roof orientation in the Manchester area, with average shading conditions. Savings calculations account for both reduced grid imports and Smart Export Guarantee revenue from any surplus electricity exported to the grid.

Calculate Your Savings

Understanding Your Results

System size is calculated based on your annual consumption and available roof area. Most Manchester homes can comfortably accommodate systems between 3 and 6 kWp.

Annual generation is based on typical Manchester solar irradiance (around 950 kWh per kWp peak per year) adjusted for your roof orientation. Real-world generation may be 5-10% higher or lower depending on your specific property conditions.

Annual savings include both displaced grid electricity (assumed at 28p per kWh average) and Smart Export Guarantee revenue (assumed at 15p per kWh). Battery storage increases self-consumption from approximately 35% to 75-85%, dramatically improving total savings.

Payback period is the time required to recover your initial investment through annual savings. After payback, the system continues generating electricity for many more years — typical operational life is 25-30 years.
