Problems with supplying of the autonomous house with energy from the renewable sources:
Solar collector inefficiency

Economical use of solar energy: solar heat collector* fault.
...The honest designers of the house heating systems say, that solar heat collectors only "help in heating and economize biofuel".

explanation:
Solar heat collector, solar heater - an "ordinary" solar collector without a reflector; a device to produce heat energy from sunlight power.

From KThesaurus by Daniel Naber:
Solar dish, solar collector, solar furnace - a concave mirror that concentrates the rays of the sun; can produce high temperatures.

The ideal place for using of abundant sold on the market solar heat collectors for the individual use is planet Mercury.

The sun does not run on the firmament, there is no atmosphere - nothing detains the sunlight, convection does not take away heat, completely absent "meteorology" (together with wind, dust, hail, hoarfrost, wet snow, ice). On Mercury birds do not foul with poisonous dung on the solar collectors and do not scratch them with their paws, trees do not create shadows. In conditions of small gravitation combining with the absence of wind, snow, rain, make possible to construct light, elegant solar collectors.

Yes, Mercury is the ideal place for solar collectors. For us, being in the terrestrial conditions it was necessary to think, how it is right to use solar collectors.

The analysis of solar heat collectors construction showed, that for their effective work rays of the sun should be concentrated on the converter of the sun radiation into heat energy. Ordinary, for this purpose are used expensive aluminum mirrors. To concentrate the sunlight we decided to use reflector from tent fabric and aluminum foil. This will reduce cost of the solar energy at least 50 times. In this way, use of cheap reflectors will drastically lower the price.

The problem of guidance of the sun is solved by usual clockwork.

By the incomprehensible reasons, producers of solar heat collectors approach to complicate and rise in price constructions, so that solar heat collectors give the temperature of 65 degrees C and above. However, obtaining such a high temperature is more expensive, especially during the winter. For this reason the honest designers of the house heating systems say, that solar heaters only "help in heating and economize biofuel".

Our heat energy system provides "consumption" of heat energy of any temperature. In a certain situation, even temperature of +10 degrees C from the solar collector is an energy source for it.

Since there are no stringent temperature requirements in heat energy system, obtained from solar heat collector, then the construction of converter is very simple.
