The Stirling solar dish mixes a parabolic focusing dish that includes a Stirling heat engine that regularly drives an electric generator. The benefits of Stirling solar over PV cells are the higher conversion efficiency from sunlight into electricity, plus a longer lifetime. Power Tower A solar power tower includes a wide array of heliostats or tracking reflectors that focus light on a central receiver over a tower. It is being widely used for certain purposes, such as providing your home with an alternative source for energy and electricity, thereby allowing you to greatly reduce the cost of your energy and electric consumption by a considerable margin. Certain solar energy systems provide you with different advantages and benefits depending on what you intend to use them on. You can get the power you need day in and day out. Solar power is a renewable resource which means that you do not have to pay any bill or keep replacing parts to get the results that you need. The disadvantage in terms of availability is that you cannot access the energy if there is no sunlight. You cannot rely on solar power at night or in places that tend to be very cloudy for several months. Solar power is quickly gaining popularity all over the globe. It is growing at a rate of 2% per year, and if the figures continue to grow, solar energy will be the preferred source of energy worldwide. Most modern nations are encouraging people to rely on this renewable resource so that they can save more and help conserve the environment. Hydrogen is a tremendously destructive component that can be found in H-bombs, and also produces dangerous fallout for those exposed. These known dangers of solar energy may sound very threatening, but these are not the only things that you should be worried about, for solar energy could also have other not so well-known dangers that could pose a risk to your health. Building Your Own Solar Power Generator You can use parts that are available on the internet or your local store. You can create a tiny solar power generator with a budget of only $200 to $300. This is ideal for power failures and life outside the power grid. The setup can also effectively power the modem, television, DC appliances, computer, cameras and lights.
