Solar energy, radiant light and heat from the sun, has been used by humans since old times using a variety of ever-evolving technologies. Solar energy technologies comprise of solar heating, solar photovoltaics, solar thermal electricity and solar architecture, which can make substantial assistance to solving some of the most vital problems the world now faces. Solar Thermal uses the sun’s heat straight to heat up another medium – usually water – without the requirement to generate any of that annoying electricity. Solar thermal systems use either flat plates or tubes to capture the sun’s heat and transfer the heat into a fluid. Solar thermal is typically used to increase the creation of hot water. I use the word increase, because there will always be days when you don’t have enough sun to produce all your hot water requirements, and the increasing is performed by either an electric element, a gas fired heater or (less commonly) other fuel heaters such as wood fired stoves. You will have seen the ‘solar thermal’ systems on roofs which typically look like tray made of glass.
In the previous 10 years, homes with rooftop solar arrays have gone from rarity to commonplace. Getting solar systems in the middle-of-the-road residential market has proved to be challenging as it has customarily been an costly technology to apply. But the technology has matured over the years and this has meant that the long term cost-cutting benefits easily overshadow
the preliminary cost of execution. Besides, it provides clean energy with no greenhouse-gas emissions.A typical solar power system uses arrays of photovoltaic cells to convert sunlight directly into electricity which is then stored into high-energy density batteries via a charge controlling circuitry. In Australia, the most important factor when choosing an installer is to ensure that they are “Clean Energy Council Accredited”. This is a prerequisite that they need in order for the government to pay out its rebates. And even more important than that is you can be confident that they have been trained in the safe installation of Solar Power Systems. You can sign up for free solar quotes at various websites and compare the prices offered by them to install the solar panels. Also you can provide with the correct size of the home and they will provide with the proper information on what is the right size of Solar panels that are required for your home in order for you to be provided with continuous supply of electricity.
When it comes to costing, obviously this is very important, but it may not be the most significant factor in your purchase. Remember, this is a system that you will depend on every day for 20-40 years, so it is critical that you have a system that has a quality and performance that you are happy with. As is true with most things in this world: you generally get what you pay for. If you have been offered a system that seems spectacularly cheap then you may want understand that there are drawbacks associated common to a lot of super cheap solar deals.
