Future development of solar energy



In terms of specific operations, the research on polycrystalline silicon solar cells should combine research and introduction to establish an annual production capacity of megawatt-scale production lines as soon as possible. Monocrystalline silicon solar cells focus on improving the efficiency of components and reduce production costs. Accelerate the development of new solar energy battery. Specific standards: MW-level polysilicon solar cell module production line of the main technical and economic indicators: component efficiency of 13%, component life of 20 to 25 years; monocrystalline silicon solar cell module production line of the main technical and economic indicators: the efficiency of 14% 15%, component life of 20 to 25 years.


To rapidly develop under the conditions of the existing technologies, the solar cell industry should realize the industrialization of small-scale optical power supplies as soon as possible; focus on the development of serialized, standardized and commercialized grid-connected photovoltaic power generation technologies for independently operating photovoltaic power plants of less than 100 kilowatts capacity, Scale applications do a good job in preparation.


In terms of specific standards: industrialization of low-power photovoltaic power Range of power: kilowatts, 100 watts Industry scale: total capacity of more than 1 MW System cost: 30% lower than the average price of the "Eighth Five-Year Plan" Solar energy; Standardization, commercialization. Power Range: 10kW ~ 100kW System Cost: Reduce by more than 30% from the average price of the "Eighth Five-Year Plan"; Study and demonstration of grid-connected PV power generation technology. Preliminary research on megawatt grid-connected photovoltaic power plants, development of 10-kilowatt grid-connected photovoltaic demonstration power station, development of 100-kilowatt grid-connected photovoltaic power station inverters, operation of photovoltaic power stations and power system related technologies.
