Energy Efficiency - Solar Services

With the ever increasing rise in energy bills, solar systems and technology can help you make considerable savings.

The sun is the source of most renewable energy supplies and there is a strong opinion across the UK that as a country we do not have enough sunshine to make solar panels worthwhile. BUT in parts of the UK we have enough solar radiation annually that the levels actually equal to 60% of those experienced at the Equator.

However this amount of energy is not received consistently throughout the year.

Approximately 70% of the UKís annual radiation is received over the period of April to September and 25% of that, is received in the months of June and July.

Solar Thermal Energy Systems and Solar Photovoltaic Energy Systems is about using this energy and converting it into a form then it can be used in building and industry, displacing conventional energy sources.

Solar Thermal Systems

Solar Thermal Systems need to be able to absorb, retain, transfer and store the solar energy as efficiently as possible. For this to happen their needs to be certain pieces of equipment in place. These include; a collector (panel), a controller, a pump and a hot water cylinder.

The controller is used to measure the temperature of the water that is in the panel and this then compares it to the temperature of the water that is in the cylinder. If the temperature of the water that is in the solar panel is more than 6 degrees higher, than the water in the hot water cylinder then the controller will turn on the pump and it will transfer the heat from the solar panel to the hot water cylinder.

Solar Photovoltaic

Solar Photovoltaic modules generate and store electricity from the sunís energy through the use of rechargeable modules. They produce energy that contributes to the running of appliances and lighting within the home without harming the environment.

The energy that is produced within the panels from the sunlight will feed into a battery. An inverter will convert the direct current electricity from the panels into alternating current. The electricity that is generated by the solar panels is then transferred through the controller which will allow the electricity to be turned on and off so it can be used for electrical domestic units.

An example of how effective it can be is in the following example;

A typical domestic system can save approximately 1.2 tonnes of carbon dioxide per year, adding up to almost 30 tonnes over a system's lifetime.

The Enhanced Capital Allowance Scheme

The Enhanced Capital Allowance Scheme (ECA) allows businesses to claim 100% first year capital allowance on investments in energy saving equipment, against taxable profits. (information taken from
