Be Very Thorough When Deciding To Go Solar

By Nora Jennings


With today's global practices on renewable energy sources (RES), the options on offer include hydro, solar, wind, geothermal, hydro power, energy, ocean currents, waves, tides and the temperature gradient of sea water. You can even get power from the temperature difference between the air and the ocean, geothermal, and biomass like animal, vegetable and household waste. Many forecasts say that deciding to go solar is a case of choosing one of the most promising renewable energy sources.

The development of solar energy is also associated with large-scale renewable energy support programs implemented in the developed countries of Europe, USA and Japan.The amount of solar energy reaching the Earth exceeds the energy of all the world's oil, gas, coal and other energy resources, including renewable ones. Using only 0.0125% of this could provide all of today's global energy needs and the use of 0.5% would fully cover humanity's needs in the future.

In general, experts use an incidence angle of 50 degrees from the perpendicular pane, as in this range, almost all the supplied radiation per day is stored on your light collector. In fact, these ratios show how well a particular collector is able to absorb radiation inclined at it. To improve their optical performance, collectors are used with different methods of modernization.

Experts know that they can use this to reduce the use of special anti-glare reflection coating. This will help you to reduce the heat absorbed in your glass, which is due to the minimal amount of iron oxide. Typically, to overcome the optical losses of the collector, transparent insulation is done in the range 8-5%.

When you have a perpendicular direction of the solar radiation at the surface of the flat collector, things are not quite the same. However, in practice, during daylight hours, a drop in the volume of rays occurs in a short period. Light rays enter under different angles onto a specialized collector, according to the time of day and the season you are in.

Photovoltaic systems are based on film-thin modules. They are easily scalable, flexible to use and install. These modules may be used not only in the construction of large power generation facilities, but also the construction and reconstruction of commercial, residential and social facilities in order to save on the electricity consumed from the network, as well as stand-alone or backup power. One should also mention the possibility of using these modules as an innovative material used in facades, glazing and the roofs of new buildings.

The sun can be called the most important element of the future of architecture and this is confirmed by the experience of using such technology in the world. You can distinguish several types of this, using thin-film photovoltaic modules that meet the needs of different users. A fit system is used in industrial plants, for large installations and is generally determined according to the installation site.

You can do a set up in open spaces ("solar parks"), on the flat, or pitched roofs of buildings and even on the facade of the building. A good system will be an additional source of electricity (to help you save energy during the day. It also makes for a good autonomous source of power (in the absence of a common power grid).
