Solar power system is made up of solar panel, controller, storage battery, and inverter. Solar panel is the core component for solar power system, how to improve the conversion rate and reduce production cost are two main problems to solve. Presently, the efficiency of solar cells have reached about 18%~19%, the efficiency of solar modules…
The energy conversion unit of solar power system is solar cells. The working principle of solar cells generation is photovoltaic effect. Solar cells absorb sunlight energy when it is radiated by solar, to produce photoelectron named as electron-hole pairs. The photoelectron and electron hole would be separated under the function of electric field built-in battery,…
With the gradual approach of fossil fuel crisis and sharpness of environmental problem, to develop renewable energy is extremely urgent. Solar energy is unlimited storage, widespread existing, cleaning exploitation and economic developing, etc, which makes it become ideal alternative energy. In the meantime economic development, energy-saving is also the important problem that society faces. LED…
With the gradual development of technology, the technique of Integrated solar street light is more and more mature, battery capacity is more and more bigger, lifespan is more and more longer, the range of application is more and more extensive. Presently, Lead-acid and glue battery have been replaced by lithium battery being utilized for solar…
Solar PV system mainly includes solar panel, DC-DC conversion device, storage battery, inverter and controller. Although solar pv control system is just one of components for solar system, it plays an important role. Control system is the “brain” of whole of solar pv system, it control whole of process which is from converting solar radiation…
Inverter is very important configuration in solar system, because AC load appliances are widely used in various areas, so, it is necessary to learn more about inverter. The power electricity that solar panel generates is Direct Current, namely, solar panel can charge battery, the battery can provide power supply for load. It need inverter to…
Off-grid solar power system means that it doesn’t connect with public grid, it is individual. The conversion efficiency of solar cells is effected by its temperature, sunlight intensity and voltage float of battery, meanwhile, these three factors would fluctuate during one day, which would be effected by the spectrum of solar radiation, thickness of aerosphere,…
Solar car is said as “future car”, it is different with traditional cars. Solar car don’t have engine, underpan, drive, gearbox, etc, it is consists of solar panels, battery and electrical machinery. Only if to control the current of electrical machinery, the solar car can be moving. There are three technical points for a solar…
Home solar power system is being pushed to develop by government and market. Government granted a lot of finance support and provide considerable subsidy to home solar system. More and more investors treat home solar project as good investment. There are many factors to push this development for home solar system. 1). The revolution of…
Suniva is a manufacturer of solar cells and solar modules in United States, the company has declared to bankrupt, under its petition, United States International Trade Commission (ITC) may implement more severe trade barrier to the import of solar pv products in the Autumn of this year. This possibility makes other Countries PV manufacturers and…
