Professional Self-Study Certification Training Courses For Solar Installation
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. Collectively they are thought to be 'Green' because they are ecologically sound and easy to replace. It is easy to think that we may be travelling back in time when we think of items such as wind power and windmills. However, it is the result of eco-efficient and planet friendly options that this process is maintained.
In the home environment, one can see examples such as Solar Thermal and Solar Water Heating Collectors. To gain electricity from roof panels you would need solar electrical panels (PV's). Biomass Energy is the next phase, and this involves Fuel, Pellets, Stoves and Boilers burning Wood. There is also the ground heat from the Sun - now known as Ground Source Heat Pumps. At the end there are two of the most mature forms of energy production in the UK - albeit renamed now to 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. Additionally, there is the method of converting solar radiation into electricity known as Photovoltaic - or simply Solar Electrical panels. Solar Panels themselves need to be away from all light blocks, and should be on south facing roofs at angles of 30 degrees from the horizontal plane.
As a result, Solar Water Power is often considered the most common form of Solar Energy in the UK. Solar Water heating systems can provide over 50 percent of a household's hot water requirement during the year. 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'. Due to its adaptability, it can produce a range of energy forms - from heat and electricity through to combinations of both. The ability to generate electricity is one of the UK's main green strengths - as it has one of the larger Biomass legacies within Europe. It should be borne in mind that the whole process is designed to produce energy without an impact on CO2. Because the system often involves one tree being planted as another is felled, many wood crops are deemed to be sustainable sources.
By the growth of Short Rotation Crops (SRC), the UK is able to maximise the 'Energy Crops' return overall. Also producing high yields of dry matter are the perennial grasses. Equally significant within this practice sit Municipal and Agricultural waste products. One natural offshoot of agricultural work is Agricultural Waste. However, waste derived from food or wood is another biomass entity - called Municipal Waste.
Geo-Thermal Energy Based Systems - The constant energy of the Sun heating the Earth results in both warm water and electricity being produced. Using the ground temperature of around 12 degrees in the UK - we can both heat and cool buildings. Heat pumps are recognised as a very good form of power generation, generally giving back four units of energy for every one used. By using energy from solar electrical panels or wind turbines to power them, heat source pumps can be almost 100 percent renewable in energy production.
Systems Based On Wind Energy: Without a doubt, wind energy has to be one of the oldest forms of energy production known to man. 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. With regard to wind generation, it is the UK that has the highest production within Europe. It is interesting to note that whilst we can produce 10 percent of our entire power requirement from wind power, at present we only produce 1 percent. Although electricity is still being produced from between 2-10 p per kWh, it could be generated from as little as 2p per kWh. The financial recovery process takes around 6-9 months.
Hydropower is a method that suits the UK energy production system. Although new in its approach, the act of harnessing energy from water has been going on for a long time. It is this type of energy production that could meet 2 percent of all the UK's demand.
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. It is by using the eroded national distribution systems, that allows for outdated sluices and dams to be used by techniques known as 'Micro-Hydro'. Having said that, this process could still generate 200mW of the National Capacity. The expected cost of installing a system such as this would be between 200 pounds and 3k per kW of output.
Due to the energy requirements worldwide, 'Green Energy' is naturally growing at a fast rate. Within the UK and mainly the domestic sector, we are well placed to take advantage of the schemes above.
Electrician and Plumbers are thought to be key in providing expertise during domestic installations. Grants and financial aid is also set to increase within the EEC and the UK - as 'Green Energy' gets ever higher status. 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.
