Solar PV System Calculator 
Its often not easy to know whether your PV system is on track or whether its not generating what it should be.  A 4kWp PV system, installed at the highest tariff rate) that is underperforming by 20% could be earning up to £400 less a year in FiT and export tariff income as well as almost £150 in potential energy savings.
Additionally it could help work out whether the panels are shaded and could benefit from an upgrade to Solaredge or just need a clean.  
Our calculator helps will help determine whether an installed system is generating as expected by comparing the expected generation with the actual generation.  
How to use

Fill out the yellow boxes.​

A) - your system size in kWp (on your MCS cert)

B) - Your estimated generation in kWh per kWp (not to be filled in)

C) - Estimated total generation per year (as shown on your initial quote)

D) - To work out your savings, enter your £ per kWh (unit) price

E) - To work out your FiT income, enter your original FiT price per kWh

F) - Estimated use of kWh - most system owners use as little as 50% of generated power

G) - Install date - when the system was activated (on your MCS cert)

H) - End date - defaults to todays date, but can be overwritten to look at a date range

I) - Your generation meter reading - take a current reading from your generation meter

Note

  • Our solar PV calculator is a excel file.  Only the boxes in yellow can be amended.

  • Performance may deviate by up to 10% a year from estimated generation

  • FiT rate increases by 2.5% RPI each year

  • Titan Eco takes no responsibility for any system or systems performance.  The estimate generated by the calculator is only an estimate of performance
