The proportion of state subsidies not affect the promotion of large-scale applications

Be seen from Table 1, the construction of a smaller-scale thin-film photovoltaic solar greenhouses have several hundred thousand dollars, the larger may need a few million dollars, or even billions. "Golden Sun Demonstration Project" currently undertaken by our country in order to promote the development of the solar panel photovoltaic industry subsidies up to 50% the proportion of applications in facilities on agriculture greenhouses, remain too high input costs, the risk borne by businesses and individuals, therefore affect the promotion and application of large-scale thin-film photovoltaic solar greenhouses.

(G) thin-film photovoltaic solar greenhouses structural load-bearing demanding, high cost of renovation of existing agricultural greenhouses

The thin film solar cell is commonly used Shuangbo package, the component thickness is 6-7mm, the conventional photovoltaic greenhouse insulation glass thickness of 4mm, the thickness difference between the two 2-3mm, of original agricultural greenhouse structure bearing can not meet the PV The components of the load-bearing requirements, the need to transform and upgrade the existing agricultural greenhouse structure, which also led to thin-film photovoltaic solar greenhouses overall increased inputs limits the large-scale use of thin-film photovoltaic solar greenhouses.
 Third, thin-film photovoltaic solar greenhouses development prospects

The new century, China's rapid development of facilities for agricultural facilities agricultural area from less than one million hectares in the last century to more than 300 million hectares development of all kinds of agricultural greenhouse area has been ranked first in the world, in which the high-grade glass greenhouse, the plastic greenhouses construction area has reached more than 200 million hectares. For the solar photovoltaic industry, if the top of these facilities agriculture greenhouses can make full use of space, can not only save a lot of land resources, but also in the case does not affect the normal production of the greenhouse crops make full use of the facilities for agricultural greenhouse as a solar PV the generation building foundation. Electricity generated resources can be provided directly to the greenhouse lighting, rolling machines, irrigation equipment, heating and cooling equipment, etc., can also supply the surrounding residents and farmers production and life.

Under the current oil prices are rising, the energy crisis are frequent, global warming, energy conservation has become the main theme of the times the background, and vigorously develop green alternative energy, the development of low-carbon economy, and to promote and achieve sustainable development has become the world faced a common choice. To develop solar photovoltaic industry, and make full use of solar power is the best solution to the current energy crisis. Thin-film photovoltaic solar greenhouses both industrial projects, and efficient agricultural projects, with the efficient use of solar power, BI standardization of low-carbon agriculture development and facilities for agricultural production, and actively implement the national energy conservation policy around the development of green energy, alleviate China The energy shortage has opened up a new channel, and also has great significance for the promotion of agricultural transformation and upgrading, improving agricultural enterprises and farmers' income. With the continuous improvement of our thin film photovoltaic solar cell technology, a gradual reduction of the cost of solar photovoltaic systems, as well as thin film photovoltaic solar cells, the key facilities for agricultural applications technology research, as well as national support efforts to continue to increase its facilities for agricultural greenhouses on the application of the prospects are very bright.

Hangzhou development of thin-film photovoltaic solar greenhouse conditions analysis

Hangzhou "second five" proposed to accelerate the development of modern agriculture, high-yield, high-quality, efficient, ecological and safe for development-oriented, perfect modern agricultural industrial system. One important aspect is to accelerate the pace of agricultural development of the city's facilities, promote the transformation and upgrading of the city's agricultural and give priority to the development of low-carbon agriculture.

1, the city's facilities for agriculture has developed rapidly, the considerable area of ​​facility agriculture greenhouses, provides the basic conditions for the development of thin-film photovoltaic solar greenhouses.

According to statistics, the various facilities of Hangzhou cultivation greenhouses area of ​​nearly 60,000 acres, which has exceeded 2 million acres of the high specifications greenhouses (glass greenhouse), and all the facilities of the city cultivation greenhouses are plastic film or glass-covered Lord. Hangzhou area relatively adequate light, sunshine hours 1800 to 2100 hours, the annual average global solar radiation between 100 to 110 kcal / square centimeter. It is estimated that a 1100mm * 1400mm thin-film photovoltaic solar panels daily average power of 0.4 degrees, an area of ​​an acre of greenhouses year theoretically power nearly 40,000. If the city's facilities cultivation greenhouses large area thin-film photovoltaic solar cell greenhouses year can theoretically generate hundreds of millions of degrees, not only can save a lot of power resources, to achieve a low-carbon agricultural development, but also for improving the greenhouse plant growth conditions, the development of intelligent dimensional agriculture, adjustment of agricultural structure, improving city facilities for agricultural level of equipment and facilities agriculture per unit of output have important practical value.

The emergence of thin film photovoltaic solar greenhouses, provides a good opportunity to accelerate the development of modern agriculture in our city, the level of agricultural equipment to improve the city's facilities, promote the transformation and upgrading of the city's agricultural and give priority to the development of low-carbon agriculture and intelligent stereo agricultural.

2, the city's solar photovoltaic industry rapid development, the formation of certain industrial base and technical reserves of high-tech solar photovoltaic enterprises, to provide technical support for the development of thin-film photovoltaic solar greenhouses.

Hangzhou "12th Five-Year" presented to vigorously develop the solar photovoltaic industry to accelerate the development of new energy industry as the core of the solar photovoltaic, increase green energy demonstration application. Especially in the past two or three years, Hangzhou solar photovoltaic industry rapid development, the formation of a considerable number of certain industrial base and technical reserves of high-tech solar photovoltaic enterprises. 38 According to statistics, the city's enterprises involved in the solar photovoltaic industry, the formation of the solar cell output of about 255MW sales output value of 2.617 billion yuan. Tianyu light, Chint Solar universal Solar, Green China Energy, Long Yan energy strong core competitiveness of enterprises to introduce advanced foreign technology in thin film photovoltaic solar cell production has advanced technology and production line; but also in the photovoltaic power generation system components and applications Tianyu light, Chint Solar, solar charge controller universal, Zhejiang University Sunny Energy, Shuqimeng photovoltaic electronic Lianlong, Lung Chi curtain wall enterprises to get involved. Enterprises and research institutes conducting technical research in new product research and development of amorphous and microcrystalline silicon thin film battery as well as single crystal silicon thin film battery. In short, the basis of the city's solar photovoltaic industry for the development of large-area thin film photovoltaic solar greenhouses provide a strong technical support.
