System Size and Output Installed System Size Estimated Annual system output (EASO) Estimated System Performance & Feed In Tariff illustration The performance of Solar PV systems is impossible to predict with certainty due to the variability in the amount of solar radiation (sunlight) from location to location and from year to year. However, it is possible to estimate the performance of a Solar PV system and the UK Microgeneration Scheme requires all certified companies to also give an assessment of system performance using a standardised approach based on the Government's Standard Assessment Procedure (SAP) This estimate is given as guidance only and should not be considered as a guarantee of performance kwh ,20 kwp kwh System Cost Fully Installed cost (inc VAT) (Cost) Fit Income Feed-In-Tariff rate (FiTrt) 25 year FiT Income (FiTinc) Basic Payback Calculation Proportion of electricity generated consumed on premises (EConsPrem) Proportion of electricity generated exported to grid (EExpGrid) Standard Import Tariff (IT) Proposed Export Tariff (ET) 6, ,356 50% 50% Annual Value of electricity consumed VElecCons = EASO x EConsPrem x IT Annual Value of electricity exported VElecExp = EASO x EExpGrid x ET Total Value of electricity generated VElecTot = VElecCons + VElecExp + FiTrt Basic Payback PayBk = Cost / VElecTot 7.96 Years Annual Return on Investment ROIann = VElecTot / PayBk 2.56% - Page 3 -

This estimate is based upon the Government's standard assessment procedure for energy rating of buildings (SAP) and is given as guidance only. It should not be considered as a guarantee of performance kwh per Month kwp stands for Peak Power. This is the maximum amount of energy a solar PV module will produce under standard peak conditions. The standard peak conditions are,000 watts per square meter under Peak Conditions (25 dgerees celsius with perfect direct sunlight). kwh is the amount of energy the PV module actually generates under normal conditions. The above data is taken from the NASA website and is an average for the South of England. This should not be taken as an exact set of data and should only be used as a guide.

However, many people are surprised at how little affect there is by a panel system facing West rather than South. Comparatively, many are surprised at how the smallest bit of shading can affect the panel performance. Getting the right system installed, so that it maximises your system performance can make a huge difference. System direction and roof angle and expected performance ratio: Shading effects on system performance: System Shading Level Performance Heavy 50% Significant 35% Modest 20% None/little 0% As you can see, the effects from shading can be much more damaging to system performance than the direction of the panels. Micro Inverters can be used to help mitigate the effects from shading, although it is more important that you get a system designed that best suits your needs and circumstances. Even the design of whether the panels lay landscape or portrait can affect the system performance... Page 7 - End
