Case Study

This case study demonstrates the return on investment based on a 14 Solar Panel system.

By taking into consideration the Feed-in-Tariffs and export tariffs, combined with SAP generation ‘data’ we are able to calculate the likely financial profit over the next 25 years as £51,779.

14 Solar Panel System

Please note that these figures are only assumptions based on electricity costs of 14 pence (inc VAT) and an RPI increase of 8.1%.

Premium 240 Watt Panels - Assumptions

  • Cashback (FIT) revenue starts at 21 pence per kWh.
  • Export based on 3 pence per unit.
  • Initial electricity costs of 14 pence (inc VAT).
  • Unit cost of electricity rises by 8.1% average.
  • Manufacturers data on PV yield has been factored in.
  • Figures based on an average power tolerance of +9%
