Green Deal Solar Energy

Solar energy comes under the category of microgeneration under the green deal scheme. Green Deal solar PV, Green Deal solar thermal, Green Deal ground & air source heat pumps, Green Deal biomass boilers and Green Deal micro chip are all the included measures under the microgeneration category of the green deal scheme. When a Green Deal assessment is being undertaken, the revenue a household will generate via the government feed in tariff from solar energy, will not be considered when calculating energy savings, to determine if the measure will meet the green deal golden rule. However if the microgeneration green deal measure is installed, the household will be eligible to the feed in tariff payment. Green Deal Solar Thermal:

Green Deal solar thermal, is the installation of panels fixed on to your roof space to provide a property with hot water. One or two green deal solar thermal panels would be adequate to provide a property with enough hot water. Solar thermal collectors are a highly efficient way of harnessing the free energy emitted from the sun. All solar thermal
collectors have tubes containing a heat transfer fluid that circulates around the system and is heated by the sun. Energy from the heat transfer fluid is transferred to your store of hot water via a coil heat exchanger inside your hot water cylinder in your home. Temperature sensors in the collector and at your cylinder help regulate the temperature of your stored hot water and ensure you get the maximum efficiency from your solar thermal system.

Migrogeneration systems like Green Deal solar thermal will also benefit from the soon to be launched Renewable Heat Incentive. The RHI is likely to be a payment made against the energy a household generates through installing solar thermal. This payment will be paid at a fixed rate over a 7 year period. This method of payment will work in a very similar way to the current feed in tariff.

Green Deal solar thermal will save around £200/£300 per year on the average energy bill by generating your own hot water.

Green Deal Solar PV:

Green Deal solar electricity systems can be used to run lighting and appliances. They capture the energy created by the sun using photovoltaic (PV) cells, which convert light into electricity. The direct current (DC) is converted by an inverter into alternating current (AC) which can then be used in the home as an electricity source. These systems can
either be connected to a battery or can be linked directly to the national electricity grid.

The strength of a PV cell is measured in kilowatt peak (kWp) – which is the amount of energy the cell generates in full sunlight.

There are now good options in sizes and colours of green deal solar panels and a number of different ways in which they can be attached to a property. Transparent cells are available that can be used on conservatories and glass. Grey “solar tiles” are designed to mimic a standard roof tile and can be placed over existing tiles or can replace the roof covering itself to provide a very streamlined finish. Green Deal solar panels can be installed onto canopy arrays or panels attached to the side of a building or can be mounted onto canopies within vertical building facades. Panels can also be mounted onto a free standing frame and which can then be used to provide shade at the same time as generating home grown electricity.

Stand-alone solar PV installations are a good consideration to generate electricity in remotely located properties, especially those that have no connection to the national grid. The PV installation can be combined with storage batteries and the modern power inverters allow the power generated from these PV panels to be fed back into a UK
mains supply.

Green Deal solar PV is reserved for the larger installations ranging from 6 to 20 panels on a roof. Solar PV has proved to be an extremely popular Green Deal installation because of the attractive returns from the Government Feed in Tariff.

The electricity generated from the green deal solar PV panels would be used to power the property, resulting in lower electricity bills and protection against ever increasing fuel costs. Up until now some people have deemed this Green Deal measure as unattainable due to the costs of installing the panels. However now with the Government backed
Green Deal initiative qualifying properties can have the panels installed at no up-front cost.

Work is still in process as to just how Green Deal and the feed in tariff will work together, however it is expected that installing Solar Pv will save a property up to £350 per annum on electricity bills and earn up to a further £750 from feed in tariff payments.
