Photovoltaic technology policy remains uncertain technological breakthroughs




PV industry a much-anticipated introduction of a fixed electricity price delay, and photovoltaic power station in the new round of tendering declaration programs fail. The current pace of progress in photovoltaic technology decision-makers clearly did not meet expectations, introduction of more robust policies also need to have a more clear industry breakthrough, and power generation costs.

Indeed, the cost of solar power project in last year's tender show in Dunhuang amazing "one drop" from the past up to 4 yuan per kWh electricity price of around about 0.69 yuan to a minimum offer / degree, in price 1.09 yuan / kwh. 13 PV companies in the industry even claim that in 2012, PV 1 yuan per unit of electricity price target.

However, a dramatic decline in cost of power generation is not entirely due to technological progress, but more importantly because of polysilicon raw materials prices collapse. Polysilicon market in 2008 experienced industry-wide downturn, most businesses were shuffling out, polysilicon prices decline, making over 40% of the total cost of photovoltaic cells to lower component prices.

Apart from photovoltaic cell components, including the cost of PV power inverter, power transmission and distribution systems, solar bracket, power station construction and land cost of installation, including inverters and other hardware devices dominates the total cost of weight. And because high-tech inverter products do not scale in domestic production, the price has been high.

It is precisely because the past two years have seen rapid development of photovoltaic industry in the process of various non-normal factors, support PV industry started to slow down the rhythm. Why has not issued the relevant departments for industry looking for a fixed electricity price, people close to the National Energy Board that the current policy-making departments also do not see the PV industry has a major technological breakthrough. Photovoltaic conversion rate on the current terms, although laboratory has reached 25% conversion rate or even higher, however, after the industrialization of how much can be achieved in the end, the cost can reduce the number, now is not clear.

2009 China PV industry was considered to start the "Year One." Last year in March, the Ministry of Finance, Ministry of Housing and Urban launched the "Solar Roofs Initiative"; the same year in July, the Ministry of Finance, Ministry of Science, National Energy Board jointly issued a "demonstration project on the implementation of the Golden Sun's notice." The introduction of these two policies was once inspired to make photovoltaic industry, long-term "two out" of the PV companies seem to see the huge domestic market, good start.

However, after a period of policy implementation, industry enterprises found that the two policies is not enough subsidies and support to boost domestic demand, experts and businesses began to urge implementation of the "Tariff Act," a fixed electricity price in the form of support PV industry.

Photovoltaic electricity industry has been that the Internet is an ideal fixed support policies, to give investors a fixed, clear return on investment expectations, establish clear long-term planning, reduce the price by successive way to motivate technical progress. To model the form of the current domestic and network operation of photovoltaic power plants, electricity price entirely by the local government according to the particularity of each demonstration project may be, there is no single standard.

In fact, policy makers, the minimum investment in leveraging industry is the largest of its policy of pursuing the best results. With photovoltaic technology breakthrough advances have been significantly lower the cost of the path is becoming clear, the PV industry is expected to support the plan timely icing on the cake.

PV Enterprise has now increased the efficiency of energy conversion and reduce the cost of photovoltaic power generation to seek new technology path, while constantly improving existing photovoltaic conversion efficiency, on the other hand, some companies and research institutes is studying the solar light, heat utilization. Empirical data shows that solar energy if the shine is 100%, 10% of the panels will be reflected away, assuming the conversion efficiency of solar PV 20%, then there will be 70% of the solar energy into heat, and this heat to use potential for very large, but also reduce the cost of electricity will become an important way.
