Solar Panel Case Study - PV 'in roof'


This interesting installation on a new ecobuild in Lewes, East Sussex combined solar PV, solar thermal and windows into one uniform roof surface. The system is MagaSlate (manufactured by 3S Swiss Solar Systems AG) and the various elements operate as large roof tiles thus dispensing with the need for normal weathering components.

The solar PV system comprised 22 x MegaSlate II monocrystalline 160W modules to give 3.52 kWp. These were connected to a SMA Sunny Boy 3000HF-30 EU inverter


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 under review. Payments are also made for 50% of every unit generated by the PV system. This is known as the Export Tariff and is currently under review. These payment rates are fixed for 20 years, linked to the Retail Price Index (RPI) and are tax-free. PV systems installed from 1 August 2012 will be subject to an approximate 7% decrease in the FIT rates.
