Solar energy is mainly obtained by converting sunlight to electricity. This is achieved either by making use of PV or photovoltaics or by indirectly using CSP (concentrated solar power) systems. In the case of concentrated power systems, they will be using certain mirrors or lenses and will then be tracking the systems for focusing into a huge area of the sunlight on to a small beam. On the other hand, the photovoltaics will be converting the light into electricity with the aid of photoelectric effect. Solar photovoltaics, solar architecture, solar heating and solar thermal electricity are some of the solar power technologies which will be able to make considerable contributions for solving out various issues.
The solar power is mainly classified into two groups: active and passive solar. The classification is mainly done based on the way they are capturing, converting as well as distributing the solar energy. Some of the active solar power methods may include the usage of solar thermal collectors and photovoltaic panels for harnessing the energy etc. On the other hand, the passive techniques may include choosing materials which are having light dispersing properties or satisfactory thermal mass, positioning the building to Sun and also designing some spaces which will naturally circulate the air.
One of the added advantages with the active solar power technique is that, it will intensify the energy supply and are mainly said to be ‘supply side technology’. However, the passive solar technology will aids in reducing the necessity for other resources and is most often considered as ‘demand side technology’. One of the greatest benefits of the solar power is that, it will be utilizing free energy resources from the sun. This is the technique which is mainly used for the generation of electricity. This in fact can save money too.
Even if any extra power is being produced, it can be sold out to various utility providers for profit. Other than just saving money, the use of solar energy will also aids in making money to some extent. In addition to this, there are several other advantages too. You don’t have to do maintenance work at regular intervals. On the other hand, the cost which is associated with the maintenance while considering long term basis are found to be too low. Another added benefit is that, the solar power is considered as a source of energy which is renewable.
Even though it is not found to be not used up on cloudy days as well as during night time, you can depend on its availability on each and every day. The solar cells are said to be good collectors. They will not be producing any sort of noises similar to that of the other sources of energy. The solar panels are said to be more reliable. The parts are fixed up and hence they will not be moving around. They can last for a longer period of time when compared with the other sources which are producing energy. This is found to be very clean and hence does not cause any environmental pollution.
“Mrs Foster and her son, Ken Harcombe, have built a house at Whangateau, near Leigh, which is completely self-sufficient in energy with a windmill, four photovoltaic solar energy panels, a solar water heater and a woodburning stove. The house cost only $200,000. But the windmill cost just over $2000, the four solar panels cost $2000 each plus $4000 for an “inverter”, which allows them to run normal appliances, the solar water heater cost more than $3000 and the wood stove, $12,000.”
Utilizing the power of the Sun to provide energy for homes has developed into a fine art. This month, Energy Awareness Month, the American Solar Energy Society is coordinating the opening of hundreds of private homes across the country for public viewing.
Whenever settlement of the outer solar system is discussed in this ng, it’s always assumed that it will be done using fusion power to provide energy, with an “edge of sunlight”, beyond which solar photovoltaics which cannot be used, around 3 A.U.
Solar hydrogen fuel dream will soon be a reality Australian scientists predict that a revolutionary new way to harness the power of the sun to extract clean and almost unlimited energy supplies from water will be a reality within seven years. Using special titanium oxide ceramics that harvest sunlight and split water to produce hydrogen fuel, the researchers say it will then be a simple engineering exercise to make an energy-harvesting device with no moving parts and emitting no greenhouse gases or pollutants. It would be the cheapest, cleanest and most abundant energy source ever developed: the main by-products would be oxygen and water. “This is potentially huge, with a market the size of all the existing markets for coal, oil and gas combined,” says Professor Janusz Nowotny, who with Professor Chris Sorrell is leading a solar hydrogen research project at the University of New South Wales (UNSW) Centre for Materials and Energy Conversion. The team is thought to be the most advanced in developing the cheap, light-sensitive materials that will be the basis of the technology. “Based on our research results, we know we are on the right track and with the right support we now estimate that we can deliver a new material within seven years,” says Nowotny. Sorrell says Australia is ideally placed to take advantage of the enormous potential of this new technology: “We have abundant sunlight, huge reserves of titanium and we’re close to the burgeoning energy markets of the Asia-Pacific region. But this technology could be used anywhere in the world. It’s been the dream of many people for a long time to develop it and it’s exciting to know that it is now within such close reach.”
1) With solar electricity, the price is only investment. You must pay 100% of your next 30 years electricity bill before you get the very first kWh. As soon as your system is installed – and paid – the power is free. Even if were profitable on such a long time compared to classic power, many people would still prefer to pay as they use it (inertia, upfront capital…)
Almost anything will burn if you get it hot enough; but asside from fission, fusion, and water power, most of the energy we use these days comes from easily combustible matter such as wood, coal, or petroleum products. Through the years we’ve learned to safely control and direct this combustion with external combustion steam engines and internal combution gas; diesel, jet and rocket engines.

Back about 1981 I was working for a lrge corporation. My fellow workers and myself through the years would discuss many different subjects. But, that year the most frequently discussed subject was solar energy. Practically anyone in the place was eager to discus the subject. Then there came those socalled “solar energy specials” on T. V. Now I feel it’s important to to take note of who the sponsors of these “solar energy specials” were. It was always a major oil company and or the federal government. So, at the time I was doing some research on energy in general in The U. S. One of the things I found out was that from the beginning up until that time most of the people in congress especially the senators had their personal investments in oil. now, if you know much about cycology you know that sometimes something implied can be more effective than something said openly. So, what they did on those “solar energy specials” was to demonstrate using an engineer with a whole wall full of degrees the most complicated system possible. By doing this they implied that solar energy was too complex for the aveage viewer to understand. They couldn’t afford to come right out and say it because that would have insulted the audience. But, they could imply it and get with it. Then, they come right out and said that it was too expensive to be practical at the present time.
