Enviko installed this 34kW system using Panasonic’s hybrid HIT modules and SMA Tripower inverters. The system was installed at Pine Trees Business Park on Unit Five’s flat roof. The new development is a great opportunity for a solar PV system, generating electricity for the office space, cutting down the cost of bills for it’s occupants. You can see from the SAP annual estimates below that the system will save 15.26 tonnes of CO2 per year and the combination of electricity savings and the Feed-in Tariff means the total annual savings amount to over £6000.
These Feed-in Tariff rates show what sort of money can be earned on an annual basis from a system of this size as well as the expected Carbon Dioxide reductions. The estimated payback of this system is 8.5 years, but as Panasonic HIT panels are much more efficient than traditional products, it may be much shorter. The table below is based on FiT rates up to 1st May 2013 and assumes 75% usage and 25% deemed export.
