[Check Solar Costs](#estimator-form) ## How our solar panel calculator works Our solar panel calculator estimates the right system size for your home in under 60 seconds. It combines your postcode, property type, number of bedrooms, building height, roof type and typical electricity spend to recommend a system between 2.8 kW and 8.5 kW – the sizes that suit most UK households. Each kilowatt of well-positioned solar PV in the UK generates roughly 850–950 kWh per year. We use that benchmark – along with average UK irradiance, a south-facing 35° pitch and your energy usage band – to calculate panel count, expected annual generation and how much of it you can realistically self-consume. Adding battery storage shifts more of that generation into evening and peak-rate hours, which is reflected in the savings figure shown on your results page. - **Inputs we use:** postcode, property type, bedrooms, storeys, roof type, electricity spend band and battery preference. - **What we calculate:** recommended system size (kW), number of panels, indicative install cost and projected annual bill savings. - **What changes the result:** roof orientation, shading, occupancy patterns and your import/export tariff – all confirmed at survey. ## Solar panel cost calculator: what UK installs typically cost Our solar panel cost calculator gives you a transparent, itemised price – no high-pressure sales call required. Costs vary mostly with system size, scaffolding, roof type and whether you add battery storage. As a guide, current UK pricing for a fully installed Greentech Renewables system looks like this: System size Panels Best for From 2.8 kW 6–8 1–2 bed, low usage £4,700 4.65 kW 10–12 3 bed, average usage £5,200 6.72 kW 14–16 4 bed, high usage £5,750 8.5 kW 18–20 Large home, EV/heat pump £6,300 Add roughly £1,600 per battery module, and £550–£900 for scaffolding depending on building height (bungalows usually need none). Use the cost calculator above to see your exact figure for your postcode and property. ## Solar savings calculator: how much you could save each year Our solar savings calculator estimates two things: how much you save by using solar electricity directly instead of buying it from the grid at 27–30p per kWh, and how much you earn by exporting surplus power through the Smart Export Guarantee (SEG). Together, a typical 4.65 kW solar panel system saves a UK household around £1,200 per year, rising to around £1,420 per year once you add battery storage. The solar panel savings calculator works hand-in-hand with the cost calculator above – divide your installed price by the annual saving to see your simple payback in years, and compare a solar-only system against a solar + battery system before you commit. Most UK homes break even in 4–7 years and keep saving for the full 25-year panel warranty period. - **2.8 kW system:** ~£800 per year in combined savings and SEG income. - **4.65 kW system:** ~£1,200 per year (the most popular UK size). - **6.72 kW system:** ~£1,600 per year for higher-usage homes. - **8.5 kW system:** ~£2,000 per year for large or all-electric homes. - **Add a battery:** typically +£220 per year per module by shifting use into peak hours. Based on these figures, most Greentech Renewables installs pay back in 4–7 years and continue generating for the 25-year product warranty period. Your personalised savings, payback and finance figures are shown on the results screen above – or speak to our team on [0333 577 7010](tel:03335777010) for a tailored quote. **Disclaimer:** This estimate is based on a south-facing roof with a 35-degree pitch, no shading, and someone typically at home during the day to maximise solar energy usage. Every home is different and a more accurate estimate will be provided during your appointment, taking into account your actual energy usage, roof conditions and other relevant factors.
