The thermal solar energy in the whole world éledező method of solar energy. China is the world's first high tower (!), Followed by the USA and Germany and Spain.

Let's have a closer Europe. Thought it would be perfectly logical if we assume that the largest users of the Mediterranean countries. Is not entirely like this:

Solar energy utilization in Europe

Germany first, followed by the sunny Spain. Surprisingly, Austria into a prominent, yet not full of sunlight striking the seventh Poland putting even more surprising is the eighth in Belgium Placing. Thought-provoking, that Hungary is the "others" with tortaszeletben still in the running category. But ...

Hungary and the 1370 kWh per year solar energy around (one square meter, set at 45 ° from the plane of energy). For comparison: the most southern areas of Germany only approach this value.

The annual amount of solar energy is correct, the problem is the unevenness of this value. In December and January together, just about. 80 kWh of energy is received that the annual amount to only 5%. Right here you should think about the legitimacy of solar energy to heating ... if a family of four daily hot water demand of approx. 11 kWh of energy we can meet. So, from December to January period, the hot water demand to meet the very ambitious task, the heating time does not make sense to talk about. For more details later.

What is a solar system? Napkollektorokból (these are collected in the heat), one or more storage tank (which is stored in the heat, then it probably does not exactly want to take a shower or may be heated when the sun is shining). These can be made is a system that can be used, although it has little concept of moving away from the black barrel.

compact solar system, the frost-free Mediterranean areas hegemonic

If you want all year round for the user to install the solar panels must be protected from frost and cooler periods of the storage tank is placed in a room heated. The first problem is widespread in round two solutions: the incidence of frost-resistant filling material (which is not ethylene glycol, or antifreeze), the other solution is known. drainback (in Hungarian with reflux) system. Both the storage solution was removed from the mechanical room (garage, store, closet hidden under the stairs, mosókonyhába, etc etc), the solar collectors and storage pipeline connects the heat pump a liquid from a public horse moves. The automatic controller monitors the solar collector and storage tank temperature, and if the collector is warmer than the storage tank, the pump will start (and "bring down" the heat of the collectors), while cooler water flows back. As long as the temperature difference exists, the pump is running. (In summer, intense sunlight in a south-facing system as early as 8 o'clock start, and continue to go up to 9-10 hours). Often asked how this temperature water can be produced? Typically, between 50-55 ° C hot water temperature offer (the formation of limescale fokozotabb higher temperatures). The collector, higher temperatures can occur (normal conditions 75-85 ° C), but the so-called. stagnation (idle) state-230cm 180 ° is possible.

Some architectural aspects:

A 2m2 flat plate collectors typically weighs 50 kg, a 30-pipe vacuum tube collector weighs 130 kg. Particular care should be exercised at a greater height of building, which has significant wind effect prevails. In this case, síktetőre mounted solar collectors must be corrected (especially síkkollektorokat), which in turn raises questions about static. May be considered a flat plate highlighting, which is a dangerous blow draining serve, then the collector is larger shadow (ie the underlying solar Síkkollektoroknál possible roof-mounted types of installation, and even hefty price, but there are custom made, or triangular-shaped collector is . placement of the vacuum tube collectors are not so flexible.

The collectors are placed horizontally, vertically, set at an angle. Consist of a flat roof can be tilted roof, the facade can be (!). However, they are not suitable for all kollektortípus such a request, the collector should be exercised when choosing carefully, and these special placements (horizontal, vertical) certainly comes at a price that is "lost" kilowattórákban occurs. The proposed method of installation and at the same time typical of the south-facing sloping roof-mounted solar panels.
