Now more than ever, the need for renewable energy is paramount for the sustainability of the future. With the continuing flow of oil leaks, accidents and damage being done to the environment, more and more people are turning to renewable energy as a primary source for powering and heating their homes. In 2011 alone, the demand for renewable energy outstripped the need for any single fossil fuel. This may not seem too exceptional or significant, but this has never before happened in the history of fossil fuels. At the current rate of growth, analysts predict that the demand for renewable energy and renewable energy technology shall rise by 8% every year until 2030.
In a recent report published in January 2012, there was stated to be a total of $260 billion invested into renewable energy during 2011 in the United States. With energy suppliers now looking towards clean energy, the demand for trained installers and technicians has never been higher. Now more than ever, roofers across the United Kingdom are looking to branch out into the renewable revolution and become some of the select few qualified and experienced professionals in the industry. With training centres all over the country, including Ploughcroft Training Solar Renewable Centre of Excellence, it has never been easier.
One of the forerunners of renewable energy technologies is solar energy; many people have seen solar panels on the homes of other people, and are interested in having them installed in their own homes, but most people are unaware of how solar power works.
Photovoltaic panels, otherwise known as solar panels (or PV), work by absorbing the radiation emitted by the sun. This energy received by the panels is then sent to an inverter within the building, which then converts the energy to electricity. This electricity is then passed through into the house or is fed in to the national grid via a feed-in tariff. Most people assume that photovoltaic panels only work during the hottest days and during the summer. This is simply not true; as the United Kingdom receives 60% of the sunlight received on the equator, you do not have to live in the tropics to make Solar PV panels sustainable. Also, during winter, the panels still receive diffused radiation during cloud cover, which means that solar panels produce electricity during all types of weather.
It is a little known fact that solar energy is also lucrative to the people who have them installed on their homes. As already mentioned, any excess energy can be transferred to the national grid via a feed-in tariff. This means that solar panels can make you money, tax free and guaranteed for at least twenty-five years. As a typical 4kWp system can save the average household £980 (US$1,540) a year on bills, photovoltaic panels can pay for themselves over and over again during their twenty-five year lifespan.
All across the country there are specialized and approved training centers where experienced roofers, electricians and plumbers are able to go and train on a variety of solar energy courses. Here they can learn, and gain hands on experience in fitting, maintaining and caring for solar photovoltaic panels. Unlike other resources, the sun has no plans of running out anytime soon, and with all energy deriving from this one source, there really is no reason not to train in solar energy, today.
