Considering Solar PV Training In The UK
It is by using natural resources such as tidal or wind energy - collectively known as ‘Green Energy’ - that we could meet our daily energy needs. They’re all considered naturally able to replenish - and thereby ‘Green’. It is easy to think that we may be travelling back in time when we think of items such as wind power and windmills. Generally, this is the result of using up to date ideas, specifically those that are planet friendly and eco-efficient.
The range of renewable energy technologies utilised within the home environment includes both Solar Thermal, and Solar Water Heating Collectors. It is equipment such as Photovoltaic Panels (PV’s) that develop electricity through suitable roof-panels. Then there are Stoves that burn Bio-Pellets - which make up the subject commonly known as Biomass Energy. Then we have the ancient energy of the Sun and the heat that comes from it - now called Ground Source Heat Pumps. Lastly, there are two of the more historical forms of energy production - namely Wind Turbines and Hydropower.
Solar Energy Systems: Also known as Solar Energy, this mainly uses two, albeit different types of solar panels to get the desired results. Initially, there is the process of obtaining hot water from the Sun via Solar Water Heating Collectors. Furthermore, there are the Solar Electrical Panels (more correctly known as Photovoltaic heat collectors) which transform 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. With the ability to provide almost half the annual need for hot water in the house, Solar Water heating systems are very important. The cost of fitting depends on whether you do it yourself (500 to 1500 pounds) or whether you get a professional fitter - in which case it will cost between 2-5k overall.
Biomass Energy Based Systems: Historically, this has come from plants and animals, though nowadays this also includes new genetcially engineered ‘energy crops’. Considering its ability to produce energy in the form of heat and electricity, this type of energy is extremely flexible. Furthermore, within the European Markets, the UK is one of the central producers of Biomass fuels. Considering all this, and the relative lack of C02 produced, makes the whole process highly green overall. Much of the UK wood crop is sustainable, in order to ensure that C02 produced during any heating process is absorbed.
A process called Short Rotation Coppice (SRC), utilising trees such as Willow and Poplar, is used to meet the demands of such ‘Energy Crops’. Dry matter is also very sought after - and perennial grasses are a good source of this. Within this process also sits the lesser known Agricultural and Municipal Wastes. Agricultural Waste is commonly formed as a by-product of traditional agricultural work. Of equal importance is Municipal Waste, which comes from recycyled wood and food.
Systems Based On Geo-Thermal Energy: Used in the generation of both warm water and electricity, this energy mainly comes from the Sun and heats the Earth. Using the ground temperature of around 12 degrees in the UK - we can both heat and cool buildings. Generally, items such as Heat Pumps are thought of as very effective, as they produce four units of energy for every one that is used for generation. A greate return of energy (sometimes almost 100 percent) is produced - because heat source pumps can operate in-line with wind turbines and solar electrical panels.
Systems Based On Wind Energy: When you consider the milling of grain and pumping of water, it is easy to see how long wind energy has been with us. Whether to your home or to a local grid, when the energy has been generated it must be delivered to a point of usage - and cannot be stored. In fact, the UK has the largest wind resource within Europe. Although we only utilise 1 percent of the current electricity capability from wind - we do have the ability to create 10 percent. Overall, electricity could be generated from as low as 2p per kWh - instead of the current 2-10 p per kWh. Because of this, it is estimated that it takes between half a year to three quarters of a year to cover the installation costs.
Within the UK, Hydropower suits the energy generation model. Just like a thousand years ago, we are utilising the energy from water. Interestingly enough, this type of energy production meets around 2 percent of the UK electrical total demand.
By using a turbine, a Hydropower system can transfer the kinetic energy of moving water into another form. By using a dam or a natural river drop, these turbines do not require water storage. ‘Micro-Hydro’ however, uses the dam and sluice systems that have been made redundant by the larger national distributions. Although a lesser known form of electricity output, this process could supply 200mW of UK demand. A micro-hydro system like this would be expected to cost between 200 and 3,000 pounds per kW of the energy.
‘Green Energy’ is growing - mainly due to the demands of the Western World. That said, the UK is well placed - especially in the domestic sector - to take full advantage of the items above.
With the rise in demand for domestic installations, both Electricians and Plumbers are well placed to take advantage of this technology. With ‘Green Energy’ rising up the political agenda in Europe, a range of financial aids and grants are becoming available. It is important to gain the correct qualifications to install these items. Electrical or plumbing training that incorporates green technology could be very useful for the future.
