Why the village photovoltaic power station has become the mainstream in the photovoltaic (pv) poverty alleviation mode?

'Construction of photovoltaic power station shall not be in debt for poverty alleviation, enterprises may not share investment. Power station construction shall conform to relevant national regulations specifications and technical requirements, the main equipment should adopt national qualification examination certification body certified products, encourage use to 'leader' skill

'photovoltaic power station shall not borrow construction for poverty alleviation, the enterprise shall not share investment. Power plant construction shall conform to the relevant state laws and regulations, standards and technical requirements. The main equipment shall be the national qualification examination certification body certified products, encourage technical indexes reach the 'leading' advanced technology. Through market-oriented entrust a specialized agency responsible for the construction of the photovoltaic power station for poverty alleviation, operation and maintenance. 'First of all, compared with the power plant model, family distributed photovoltaic access point are numerous and scattered, because of the lack of professional maintenance, high risk of failure and no scale, maintenance cost is high or low efficiency. In addition, the distributed access will lead to line loss increase, and increase the line operation and rebuilding costs. Countries released in March 2016 on the implementation of photovoltaic power generation's opinions on poverty alleviation, proposed to adjust measures to local conditions to choose the construction of the photovoltaic poverty alleviation mode and the construction site. For central and eastern land resources are scarce, can use the main village photovoltaic power station, Including family use) ； For the western and central region rich in land resources, can build moderate scale centralized photovoltaic power station. Second, in recent years, with the percentage of photovoltaic (pv) Internet increased dramatically, 'discard power brownouts' has become a sore point photovoltaic industry development, suitable for development of concentration plant for poverty alleviation in the western region is facing elimination. At the same time, most of concentrated photovoltaic poverty alleviation investment scale, investment from the government, enterprises and other various main construction, property ownership prone to disputes and disputes. In addition, according to a 2018 national photovoltaic feed-in tariff, households with distributed photovoltaic (pv) and village with collective photovoltaic power station subsidies for poverty alleviation remains the same, one, two, three types of resource areas concentrated power feed-in tariff cut 0. 1 yuan per kilowatt-hour, centralized power subsidies for poverty alleviation exit ramps. Therefore, and compared with distributed photovoltaic power station and centralized photovoltaic power station, the village power station clear property rights, investment scale is small, good economic benefit, to ensure the accuracy of the photovoltaic (pv) poverty alleviation, long-term and effective. 'Much starker choices-and graver consequences-in' the second batch of village-level photovoltaic poverty alleviation project all power stations, the total size of 4. 18 million kilowatts. On the one hand, the village power station is relatively concentrated, maintenance difficulty and cost is low, use for a long time, a longer service life. Village in the country under the condition of invariable power station allowances for poverty alleviation, the project has higher power generating revenue. Village, on the other hand, photovoltaic power station adopts the whole village construction, according to the household income distribution pattern, the balance of the income distribution in collective income, can solve the problem of 'empty villages' collective income. At the same time, as poor families out of poverty, this part of the poor families no longer need to help the poor. Under the mode of village level power station, power generation over the village collective income, which was originally used to support this part of the poor families of funds more easily used for other purposes for poverty alleviation, in order to ensure accurate poverty alleviation.
