Solar Panel Case Study - Thermomax evacuated tube collector
This Thermomax evacuated tube collector is mounted in 'landscape' format. The solar fluid is pumped around each tube so giving a high heat exchange surface area. The versatility of such a system enables installation on flat roofs, pitched roofs and vertical walls as well as on ground-mounted frames.
Feed in Tariff scheme
The FIT is a scheme in which owners of PV systems are rewarded for every unit of electricity they generate, irrespective of whether they are used on site or not.
This is known as the Generation Tariff and is currently 43.3p/kWh. Payments are also made for 50% of every unit generated by the PV system. This is known as the Export Tariff and is currently 3.1p/kWh. These payment rates are fixed for 25 years, linked to the Retail Price Index (RPI) and are tax-free. PV systems installed from 1 April 2012 will be subject to an approximate 7% decrease in the above FIT rates.
