An Introduction To Solar Training

It is the use of tides or wind to deliver our daily energy needs that form ‘Green Energy’. They are thought to be ‘Green’ due to the fact that they are easily restored and natural. If we think of some of the older energy skills e.g. Wind Power, then in many ways we are going back in time. But in the main, this is the process of utilising modern technology to provide eco-efficient and planet-friendly alternatives.

The home environment, for example, encompasses a range of energy ideas – including Solar Thermal and Solar Water Heating solutions. Equally there is electricity that is generated through roof-installed panels. A further factor revolves around stoves and boilers – which are known as Biomass Energy. We now also have Ground Source Heat Pumps – which draw out the heat left by the Sun. When we think about Wind Power and Hydropower we have two of the more common forms of energy generation.

Thermal Energy Systems: Typically referred to as Solar Energy this is mainly made up of two types of Solar Panels – each using different methods to achieve similar results. Initially, there is the process of obtaining hot water from the Sun via Solar Water Heating Collectors. Solar Electrical panels or Photovoltaic heat collectors transfer solar radiation into electricity. Obviously situated away from blockages such as chimneys etc., these Solar Panels need to be mounted on south facing roofs at an angle of 30 degrees from the horizontal.

In the UK, Solar Water Power is now one of the most sought after forms of Solar Energy. These systems are very efficient – and can deliver 50 percent of a household’s hot water requirement annually. Getting a professional fitting will cost around 2-5k, however, doing the job yourself could make it as low as 500 to 1500 pounds in total.

Biomass Energy Systems – Including all natural energy forms derived from plant and animal products – such as wood, straw, poultry litter and ‘energy crops’. As such, this is a very versatile material and can be engineered to produce heat, electricity and a combination of heat and power in the form of electricity. Furthermore, within the European Markets, the UK is one of the central producers of Biomass fuels. It should be borne in mind that the whole process is designed to produce energy without an impact on CO2. Having a tree planted in place of another (that is felled for energy production) helps overall.

‘Energy Crops’ trees such as Willow and Poplar play a major part in the process – under the banner of Short Rotation Coppice (SRC). Of equal importance is the production of perennial grasses – because of their yield of dry matter. Within this process also sits the lesser known Agricultural and Municipal Wastes. Agricultural Waste is naturally formed as a by-product of conventional agricultural activity. Municipal Waste such as food or wood can also be utilised as a biomass product.

Systems Based On Geo-Thermal Energy: By naturally heating the Earth, the Sun has the potential to generate both warm water and electricity. In the UK, we are lucky that we can both heat and cool buildings from the ground source temperature of around 12 degrees. These heat pumps do need some power to operate; but for every one unit of energy they use, they generate four units of energy in return. This system can go even further – if energy efficient items such as wind turbines or solar electrical panels are used.

Wind Energy Based Systems – The use of wind as a source of energy has been going on for thousands of years, especially in milling grain and pumping water. More recently, there has been the desire to deliver the energy created to the home – or to a local power grid. With regard to wind generation, it is the UK that has the highest production within Europe. Although we only utilise 1 percent of the current electricity capability from wind – we do have the ability to create 10 percent. Rather than electricity production running at 2-10 p per kWh, it could be run at 2p per kWh. Therefore, recovery of cost takes approximately 6-9 months overall.

Last of all there is Hydropower – an area of especial importance to the UK. The field of using moving water to release energy is a very old technique – albeit we now do this in new ways. Within the UK, this form of energy production is responsible for somewhere in the region of 2 percent of all electrical needs.

A hydropower system uses a turbine to create energy from moving water. Utilising natural river runs, or water drop-offs (through dams,) the turbines can work without a reservoir of water. ‘Micro-Hydro’ utilises a chunk of the outdated sluices and dam systems that have been killed off by the large national distribution methods. This process alone could meet 200mW of the UK requirement. Between 200 pounds and 3k per KW of energy output, is a good estimate of the overall cost of a project such as this.

Due to the energy requirements worldwide, ‘Green Energy’ is naturally growing at a fast rate. To be fair, the UK domestic market is actually leading the resurgence, with a variety of schemes.

Electricians and Plumbers in particular are expected to provide the main thrust of domestic installation expertise. With ‘Green Energy’ rising up the political agenda in Europe, a range of financial aids and grants are becoming available. As a new industry, there are a range of new certificates to gain. To that end, it may be worth thinking about combined training. You can then get plumbing or electrical training along with green knowledge.
