The research and development of solar utilization technique has had the history of decades, has become the field of giving priority to of numerous developed countries.The key of solar generator is to replace conventional boiler with focusing solar collector, and the heat energy that produces with solar energy drives the thermoelectric (al) generator generating.Existing several at present ripe relatively focusing technologies can convert the radiation luminous energy of the sun to heat energy, and as dish formula, slot type and tower, photo-thermal conversion efficiency can reach 50～80%.Solar generator only utilizes the direct emittance of the sun, and the diffuse scattering radiation of sky then can't focus on.For any one given region, owing to blocking of circadian variation and cloud layer, the supply of solar energy is step.If the solar thermal energy of collecting can be stored, just can prolong effective operating time of solar heat electric system, and schedulable electric power is provided.The sharpest edges of the relative solar energy power generating of solar generator are that the heat energy ratio is easier to storage.This can make the utilization rate of the generating equipment except that the solar focusing heat collector be improved, use long hot memory time (as 16 hours every days), the operating coefficient of solar generator characteristic is reached more than 60%, suitable with thermal power plant, thus the electric cost of electricity-generating of every degree reduced effectively.In contrast to this, because the method for storage of electrical energy (as using battery) is all very expensive, can't large-scale application, thus cause the utilization rate of the inverter of solar photovoltaic generation system and controller very low, promptly the operation coefficient of photovoltaic system can only be equal to the sunshine-duration.On average, even in the abundant area of sunlight, the annual sunshine-duration only accounts for about 1/5th of the whole year.That is to say that the operation coefficient of photovoltaic system can only reach 20%.Like this, even every watt photovoltaic system installation cost is equal to the installation cost of photo-thermal power generation system, because the difference of operation coefficient also can cause the photovoltaic generation cost to be significantly higher than the cost of solar generator.
Though the heat energy of solar generator is than being easier to storage, but, owing to the radiation intensity of solar energy can change along with the variation of time of season and every day, therefore, the temperature that absorbs the fluid of solar radiation in the pipeline also changes easily thereupon, if do not add any measure, phase missionary society reaches dozens or even hundreds of degree centigrade between maximum temperature and the minimum temperature, the huge like this temperature difference is disadvantageous for generating equipment obviously, can directly reduce the efficient of generating equipment, thereby cause the increase of cost of electricity-generating.
