Solar power system is also called a portable power supply. It is the block of charging and digit management and the block of contravariant management, two in one. Output tension shares on a direct current 12V and alternating current 220V. The solar power system can provide power to different equipment. Products are widely used for household electricity without electricity in the border outposts, and is used for power supply of petroleum, geological prospecting, etc. It is also used to supply the reserve offices.

1. Doesn't demand fuel. Use of energy of the sun demands costs practically only of installation. Further the consumer receives already free energy. Any special scheduled maintenance for solar panels it isn't required. Them it is possible unless to wipe from dust. The arrangement of panels on an eminence and at an angle 70 degrees promotes that on panels snow doesn't collect in the winter.
2. Works constantly. The solar system is regulated automatically. It doesn't need to be switched on and off constantly as the diesel. In systems of autonomous power supply on solar batteries the electricity stocks up on special accumulators. Therefore energy is available to use and day and night.
3. Noiselessness. As the electricity is made by direct transformation of energy of light, there are no noise at all. If the diesel the rumble can disturb you and your neighbors, with solar system such problems aren't present.
4. Long term of accident-free service. High-quality solar panels are calculated on work within not less than 25 years. During this time there is a gradual small power deceleration. The next 20 years the system will develop about 80% of energy of initial power. Thus, total period of service makes 45 years and above. For comparison the wind system is usually counted on 15-20 years, and the diesel for 5-10 years. Thus, as in solar panels there are no moving parts, wear and breakage are almost excluded.
5. Reliability. The solar system with guarantee develops the electric power every day from rising to a decline. Productivity decreases in cloudy weather, but nevertheless solar panels give the electric power and in this case. In this sense solar panels it is more reliable than wind turbines as the wind is much less constant, than a daylight. In comparison with liquid-fuel systems it is possible to assume that the diesel is more predicted and reliable in respect of providing the electric power. However, it is necessary to remember that the diesel can not be got, break, and also depends on fuel availability. Taking into account these factors solar panels can appear more reliably.
6. General availability. The sunlight is practically everywhere and it in certain cases critical advantage of solar panels before wind and diesel systems. Features of a relief, building, meteorological features, the site size, can not allow to place a wind-driven generator, and here for solar systems of restrictions much less. Solar panels require only not shaded surface, it is desirable turned on South side. Thus in comparison with the wind generator, installation of a mast isn't required, after all panels can be placed simply on a roof. Solar panels on availability of installation have advantages and in comparison with the diesel. After all far not everywhere there is a possibility of stable delivery of fuel. And sometimes such delivery is interfaced to considerable expenses and difficulties. The sun is everywhere.
7. Possibility of any change of power of system. Liquid-fuel and wind systems have a power fixed. And here at solar systems it is size any. It is possible to install the small panel and to use for the low-consuming devices. It will manage cheaper. And if it becomes clear that rated capacity isn't enough, it is always possible to increase, having delivered more panels of the necessary size.
