As the prices of oil and gas continues to go up and up, the installation of solar panels is giving many families solace and stability. The sun offers an almost infinite source of energy. No wonder so many people are rushing to install solar panels. Indeed, their popularity is increasing so rapidly that manufacturers of solar panels are having difficulty keeping up with demand. * Two Types Of Solar Panels Predominantly, solar panels come in two types. There are solar energy panels in the form of 'solar thermal collectors'. These focus solar energy into a liquid medium, usually water, heating the liquid that is then utilized as and where it is required. The other of the two types of solar panels is known as the photovoltaic module. These solar panels convert the sun's energy into electricity, which can then be distributed immediately or stored within a battery to be used later. Solar panels have been commonplace for decades. Think of calculators and watches. Many swimming pools have been heated using solar panels for years. These days, the electricity to homes and offices often comes from the cleaner alternative energy source of bigger, better, more efficient solar panels. The influence of solar panels has spread so wide that even the National Grid take some of their power from solar energy panels. * How Do Solar Panels Work? Both photovoltaic (PV) and solar thermal solar panels are made of special materials, most frequently silicon. They act as semiconductors. When sunlight hits the solar energy panels, some of the energy is absorbed within the semiconductor material. That energy knocks electrons within the silicon loose, allowing them to flow freely. Once the electric fields within solar panels are freed by light energy, they force electrons to flow in one specific way. This flow of electrons is also known as a current. By simply placing metal contacts on the top and bottom of the solar energy panels, the current can be drawn off as electricity to be used externally. The solar panels have built-in electric fields that, when combined with the current described above, will give us what we call a wattage. That is how we define the overall power of the solar panels. Why Solar Panels? There are lots of great reasons to install solar panels in your house. Top of the list is the huge savings you will make on your utility bills. Many people feel good that they are reducing their carbon footprint. Solar panels give off almost zero carbon dioxide emission. Solar panels reduce our carbon dioxide emissions by approximately 1.2 million tonnes per annum. Another benefit is the freedom of not being tied to the National Grid. With solar panels fully fitted, power cuts and unexpectedly increased electricity bills become a thing of the past. Solar panels are perfect for those living in remote areas with limited coverage by the National Grid. * Installing Solar Panels On Your Home Though there are some very good guides to making your own solar panels and then installing them into your home on a DIY basis, it is advisable to seek out a professional solar panels installation company. Ideally, the installers of your solar panels should be certified by the Low Carbon Buildings Program. It is not advisable to try to install solar panels without full training. Make certain that your solar panels conform to the local standards laid out by the authorities there. There is a number of complex technical electrical issues to be resolved as well as full safety codes required. Because of their weight, solar panels often need to be attached to a separate roofing support system. Professional installers of solar panels should have gone through all the red tape and complicated issues so you don't have to. * Getting Planning Permission For Solar Panels Installation Solar panels are most frequently fitted to the roof or along an external wall of the home. Be sure to check with the local council before doing this. In most countries, thankfully, roof mounted solar panels can be installed into most homes, though some places require detailed criteria. In England, for example, solar panels of up to 100mm in depth can be laid across a tilted roof without requiring planning permission. In Scotland, Wales and Northern Ireland the local authorities have not finalized their legislation relating to solar energy panel, so be sure to check before you go rushing in. *The Outlook For Solar Panels As people become more and more aware of global warming and climate change, so the demand for good quality solar panels is increasing. The momentum among people is to move away from old-school fossil fuels in favor of alternative, more sustainable energy options. These include hydro-electricity, wave, wind, hydrogen and solar power. Solar power is one of the most bountiful of the possible energy supplies that we have here on Planet Earth. As the technology behind solar panels improves in terms of their efficiency, so the cost of installing solar panels is falling. When added to a range of governmental subsidies, tax credits, rebates and grants, the widespread installation of solar panels onto the average householder's roof is becoming more and more realistic. As the prices are falling further thanks to local competition in the marketplace, so, it would seem that the future of solar panels is very bright indeed.
