You do not have to pay for solar energy, because it is effective and virtually inexhaustible. This is a really sufficient reason for considering of solar power as the most promising alternative means of low-potential heat energy obtaining, isn’t it? Through the use of modern solar energy technology during the period between April and October, you can opt out of the gas and electricity consumption for hot water, and during the winter months you may use this to save amounts from 40 to 60% on energy carriers.

A solar collector is the main element of any solar system. Particularly in its absorbing panels or tubes solar energy is being converted into heat. The coolant (it is usually a non-toxic freezing liquid) selects the heat and, having entered a heat exchanger tank battery, it transfers heat to water. Water is used for hot water supplying or in order to maintain the warm in a household, and chilled coolant returns to the collector, and the process repeats then. It lasts until the sun sits down. Modern highly selective coatings allow the system to work, even if the sky is overcast.

The water, which is then used for household needs flows in the simplest single-circuit systems. However, the exploitation of such reservoirs in our country is complicated by a number of reasons. Firstly, their channels may be soiled with salts because of high water hardness. Moreover, freezing temperatures happen even in late spring or early autumn. It causes the water freezing. Therefore, dual-circuit system is preferable to be used in our climate.

The coolant can circulate in the collector disk in a natural way (by heating and rushing to the top of the collector) or with a circulating pump, power consumption of which is negligible in comparison to the generated heat. Systems with coolant natural circulation are widely used in countries with warm climates and a large number of clear days (eg, in Turkey, Greece, Egypt, Israel). In our climatic conditions systems with forced circulation are more effective ones.

If there is enough large amount of solar energy to heat water, for space heating or water heating in a swimming pool, the collector is often combined with other heat generators. For example, in the bivalent plants the extra heat could be given with hot water boiler that runs on liquid or gaseous fuels. Such a system solution allows provide homes with heating in winter.

Flat solar collectors are widely used today. They work well under normal solar intensity in the period from May to October, and, moreover they completely override the need for hot water in summer. In our climatic conditions, such systems are ideal for a summer home or seasonal home stay. Relatively low cost is their unquestionable advantage.

The building of a modern flat manifold is a frame, which is made of galvanized steel or anodized aluminum, in which hail-stainless sheet of glass with low iron content (0.03%) with a thickness of about 3 mm that allows reducing of heat loss is hermetically inserted.

Luckily we live in the times when the ruling elites start to realize the value of living in harmony with the nature on this planet. And solar power grants is a realistic proof of it. If you want to switch to solar energy, please find out more about how solar power grants and how exactly you can exploit these solar power grants for your living.
