Solar and wind energy inexhaustible, can be converted into electricity, heat and chemical energy.  The two energy conversion circuit, for the far post in the high mountains, Gobi Well Station, grassland pastures electricity, as indoor lighting, communications, TV power.
1, solar power use

 Solar power in the region depends on the use of the incident light and strong sunshine rate, which in turn depends on two parameters latitude.  China's rate of sunshine throughout the year 2200 to 3000 hours.
 1, solar energy conversion device
 Gallium arsenide are commonly used batteries, battery CdS ceramics, thermal ion batteries, such as silicon cells, is commonly used silicon cells.  Its ability to absorb the sun's rays strong, the conversion efficiency is about 11 to 20 percent. Solar Power for 1 kW/m2, can produce 11 ~ 20 kW/m2 power.  Solar power supply circuit see Figure 1 A.
2, solar silicon cells-board automatic tracking system
 To make light board landed in the rising sun and the entire programme, are in the best position, a mechanical system guarantee perpendicular to the sun's rays light board.

 
 
 3, electric energy storage
 Use of nickel iron alkaline batteries, to prepare for rainy days and night use.  Battery models for the TN-500 type, voltage of 1.25 V, a capacity of 500 Ah.
 4, solar power maintenance
 (1) Kai regularly test-board surface, kept clean, especially the days after the storm, we must promptly remove the dirt.
 (2) automatic tracking system to regularly check to ensure that lubrication and rotating freely.
 (3) regular (15 days) for the battery hydrogenation electrolysis potassium wave.

 Second, the use of wind power

 The kinetic energy of air movement from the air density and speed of decision
 After wind turbines into mechanical energy and then converted into electricity generator driven by the rectifier regulator after a low-voltage DC, to supply load - lighting, communications, electric fences, and so on.  Wind power circuit see Figure 2, the main component specifications with Figure 1.  (See Figure 2 A)

 
 
 Wind power battery using nickel-iron, model for the TN-500 type, rated at 1.25 V, a capacity of 500 Ah.  Mainly for calm during the back-up power supply.
 Wind round duo are mechanical devices, to ensure that the internal gears and transmission system of lubrication should be checked every two weeks time, and injected into lubricants.  Wind power generator is the core component, it is necessary to overhaul the wind turbines at the same time, inspection of the generator rotor and bearing, if poor performance, should be promptly replaced.
