Assumptions: the yield, installed cost and export tariff above are editable defaults (950 kWh per kWp per year, £900 per kWp, 5p per kWh), not market data. Tax relief is shown at the 25% corporation tax rate: the first £1m a year of spend at 100% under the Annual Investment Allowance and the rest at a 50% first-year allowance. These are illustrative defaults; your figures depend on roof, shading, load profile, tariff and tax position. This tool does not store any data you enter.

Calculator FAQs
How accurate is this calculator?
It gives an indicative estimate from standard UK assumptions: roughly 950 kWh generated per kWp per year, a placeholder install cost of £900 per kWp that you should replace with your own quote, and a 5p Smart Export Guarantee rate for exported units. Your real figures depend on your roof, orientation, shading, load profile and tariff. A precise figure comes from modelling your half-hourly meter data.
What is self-consumption and why does it matter?
Self-consumption is the share of solar you use on site rather than export. On-site use saves the full electricity price, while exported units earn only the lower Smart Export Guarantee rate, so a higher daytime load means a shorter payback. The slider lets you set your daytime usage share.
Does the estimate include tax relief?
Yes. Commercial solar usually qualifies as plant and machinery, so the calculator shows indicative year-one Annual Investment Allowance relief at the 25% corporation tax rate. Your actual eligibility depends on your tax position and profits.
Is this a quote?
No. It is an indicative estimate to help you scope the opportunity. A real proposal needs your meter data, a roof assessment and a grid check, which a feasibility study brings together.
