Polaris solar PV net news: first, resources
Xinjiang is rich in solar energy resources, the annual sunshine time of 2,550-3,500 hours, the percentage of sunshine for 60%~80%, total annual radiation of 5430~6670MJ/m2, the annual total irradiance is greater than high latitude area of China 10%~15%, 15%~25% higher than the middle and lower reaches of the Yangtze River. Ranking second in the country, second only to Tibet, under the influence of ambient temperature and wind storm, solar energy utilization in Xinjiang’s best seasons are summer and autumn seasons. Days of annual sunshine is larger than 6 hours 250-325 days, Sunshine temperature higher than 10 ° c days generally for more than 150 days. Solar energy resources in Xinjiang, mainly distributed in the five regions (South of the tianshan mountains, tianshan North foot of Northern, North Eastern, North Central, eastern Xinjiang), solar radiation is divided into four resources. East East is rich in resources, irradiance is greater than solar years 6.601 million KJ/m2, South of the tianshan mountains for the resource rich, thousands of solar annual irradiance 580~620 kJ/square meter. Northern Piedmont of tianshan mountain resources are abundant, solar irradiance 540~580 year thousands of Coke per square metre. Central, Northern northern Northern resources sub-enriched zones, thousands of solar annual irradiance 500~540 kJ/square meter.
Second, tariff and subsidy policy
1, national policy
PV power station: according to local solar resources and construction costs, the country is divided into three types of benchmark price, develop benchmark price of photovoltaic power station.
New benchmark national PV power plant price
Distributed PV: territorial power subsidies for distributed PV policy, price subsidies for 0.42 Yuan per kWh (including tax, the same below), be paid through the renewable energy development fund, by the power companies to pay which, distributed PV systems use more than the power of the Internet, by grid enterprises in accordance with the new benchmark coal price in the local acquisitions.
2, the local policy
Xinjiang currently has no State-wide re power subsidy price policy for PV projects.
Third, economic evaluation
Xinjiang Hami, Tacheng, Altay, kelamayi area in accordance with pricing zones belonging to the class resources area, over the number of hours in 1550h; other regions belong to the class ⅱ resource area, over the number of hours in the 1450h. Photovoltaic project in two types of resources as follows.
(A) type resource area
Class resources in Xinjiang region corresponds to the PV benchmark price of 0.80 yuan per kWh. Project unit cost for 8000 Yuan, installed capacity of 10MW, annual utilization hours of 1550 hours, according to the above conditions estimated cases without government subsidies, the project financing between the before-tax yield in 10.86% before, and payback period of between 8.68, project has a certain degree of profitability.

2, distributed PV projects
Distributed PV project can select three species mode (national subsidies for 20): If select “full Internet” way, corresponds to of PV benchmark electric price for 0.95 Yuan/kWh; If select “spontaneous use, more than electric Internet”, national give 0.42 Yuan/kWh of electric price subsidies, Internet part according to local coal-fired benchmark electric price acquisition; all “spontaneous use”, is electric price for sale electric price, and national electric price subsidies price and provincial subsidies of and. According to price, item price with General commercial and industrial electricity prices: 0.516 Yuan per kWh, the project for 1MW of installed capacity, the unit cost for 8000 Yuan. According to the above conditions estimated pre-tax rate of return before the project financing 7.7%, payback period between 10.18, the project does not meet the requirements of investment income. See the following table. Since Xinjiang is China’s energy plants, various types of energy sufficient electricity prices low level, therefore the development of distributed PV projects than the Eastern load, energy shortages areas do not have the advantage.

(B) the class ⅱ resource area
Project installed capacity of 10MW, annual utilization hours of 1450 hours, calculating according to the above conditions, in the absence of government subsidy cases, the project financing between the before-tax yield in 11.33% before, investment recovery period between 8.45 and project profitability higher than class I areas.
Class ⅱ resource area PV financial indicators table
2, distributed PV projects
Item price with General commercial and industrial electricity prices: 0.516 Yuan per kWh, the project for 1MW of installed capacity reached the number of hours to 1550h, according to the above criteria calculation, project financing between the before-tax yield in 6.6% before, payback period between 11.4 years, does not meet the investment requirements of the project.

Four, filing process
According to State on promote PV industry health development of several views (country sent 24,), and national development reform Board on issued distributed power management provisional approach of notification (sent modified energy 1381,) and national energy Council on issued distributed PV power project management provisional approach of notification (country can new can 433,), about provides, PV project by the local government for record.
PV projects in accordance with the national requirements of Xinjiang Autonomous Region, photovoltaic power generation project in provincial government departments Department records, distributed PV power generation projects in (city, State) record. Regiments and distributed PV project in bingtuan development and Reform Commission for the record on the ground.
