An electrical energy storage unit: first direct current generated by solar cells into the battery storage, battery characteristics of the work efficiency of the system and features. Battery technology is very mature, but its capacity is needed by the end of the power and sunshine duration (generation time) effects. Therefore, when the battery capacity and 安时容 watt amount is determined by the predetermined number of consecutive free hours of sunshine this is a search up and down the road to seek a breakthrough. Solar photovoltaic power generation emerging new technologies. But the high price is still troubled industrial development issues. Solar electricity price is about 10 times that of thermal power generation. Some experts pointed out that with increased environmental costs of thermal power electricity price change will show a rising curve, and thin-film solar cells electricity price will vary with mass production and conversion efficiency decreased, the two curves are expected to be in the 2012- between 2015 intersection. In addition, the market outlook is not to be ignored. And to overcome these difficulties must rely on the concerted efforts of business and government. In the long term, actively expand the industrial chain business is the principle challenge China solar PV enterprises are facing, and the responsibility of Chinese PV companies is to accelerate progress in the development, accelerate technological innovation, and constantly improve the technological level by reducing the cost of photovoltaic power generation; Also Hankou solar power, the state should be introduced as soon as reasonably grid policies to address the problem as soon as possible settlement method, and producers, users and equipment manufacturers to give appropriate subsidies and so on. Meanwhile, the public should also strengthen awareness of environmental issues price of solar power, enhancing the use of renewable energy sources will. And this one has had to mention that, changing concepts is a priority, it is the key issue. I believe in government, business and the joint efforts of all the people, "sunshine plan" will not realize the Chinese dream.
