The UK government operates an incentive scheme for adopters of renewable technologies. This is known as the Feed In Tariff. The UK FiT is administered by Ofgem (feed-tariff-fit-scheme) and the subsidy is actually paid by licensed electricity suppliers with whom you register your installation once commissioned. A list of registered FiT Licensees can be found here. Other subsidy schemes operate around the world. You will need to refer to you local region scheme directly to understand what subsidies may be available.
The Solar PV FITs scheme works on the basis of being paid for the metered electricity you generate. This rate varies by size of installation, number of sites you have and whether you mount on a building or not and also if the building has a suitable Energy Certificate Rating. The FIT payment rate is adjusted by the Government on a quarterly basis and regressed in line with cost reductions in the industry. FITs are applicable for installations unto 250kWp and then have a standard rate over this size.
In addition to FITs your installation may be applicable for a Deemed Export Tariff. For installations under 30kWp, the utility assumes 50% of your power will be exported back to the grid. You are then paid an Export Rate for this electricity in addition to FITs. This is paid regardless of how much you ouse yourself. For systems over 30kWp you will need to install a Smart Meter to negotiate payment for exported electricity.
For full details regarding FiT eligibility and scheme administration you must always refer to OFGEM directly when considering project feasibility. Version5 dated April 2013 of the scheme guidance is provided here , but please always ensure you refer to OFGEM directly.
For projects up to 50kW to be eligible for the FiT, they must be registered on the microgeneration certification scheme (MCS) and be installed by an MCS registered installer.
For projects over 5MW they must be registered with OFGEM. Guidance can be found here.
Details of MCS registered products and installers can be found here.
All Polysolar products are MCS registered and qualify for the solar PV FiT. The current rates for solar Pv FiT can be found here.
For international applications Polysolar products are IEC 6164 & 61730 certified by TÜVRheinland.
