Calculations include solar radiation and system losses in a central UK location due to Temperature 6.6% and Angular Reflectance 3.1%, as well as other losses (e.g. Cables, Inverter) of 18%. You can change the Inverter/Cable loss and other assumptions if you wish.
These are the details we used to calculate your payback

These estimates are calculated assuming tax inclusive pricing including fitting of MCS certified panels to determine the best possible payback. Assuming that you pay 14.4p per unit and that around 35% of the solar electricity that you generate will be used in your home.
Assumptions:
- Illustrative solar PV performance figures only. Figures are given in good faith but do not constitute "Financial Advice".
- Exact PV subsidy figures may depend on grants available at particular locations and other factors.
- Your property has an Energy Performance Certificate (EPC) rating of level D or better.
- Yearly PV output uses a factored degradation over time based on industry estimates.
- Tariffs shown presume installation after at the new FiT rates
- VAT is included (at 5% where appropriate) unless a new build is specified.
- Photovoltaic Panels will not be shaded (e.g. by Trees or Buildings) as shading affects PV output.
- Assuming that you pay 14.4p per unit and that around 35% of the solar electricity that you generate will be used in your home, having an export meter (you can change such assumptions above).
