Parity photovoltaics: hidden costs down?

Epicenter wide net Beijing on August 20, the message ( Reporter lu advised) According to the voice of the central radio and television reception desk economy 'the world of finance and economics' report, the National Development and Reform Commission, the national energy bureau recently released 2020 pv parity project list, this kind of project total installed to increase sharply to 33 million kw or more, more than 2019 national new photovoltaic power generation capacity. Subsidies, parity project, means that a significant reduction in the photovoltaic power generation cost, obvious competitiveness.

photovoltaic power station is the biggest hidden costs?

photovoltaic volatile, rainy day power generation efficiency is greatly reduced, in the evening it barely generates electricity. So many governments require new energy power station must be equipped with energy storage equipment, storage before selling, so it can remain stable. Beijing can clean energy power feng-yang zhang, general manager said, this constitutes the largest photovoltaic power station of a hidden costs. Feng-yang zhang said: 'there is no form the mandatory standards, but each has a trend of local government, building energy storage requirements of new energy enterprises. The core aim of building energy storage is, reduce the impact on the grid and unstable output influence. '

energy storage equipment for batteries at present. Although in recent years, China's lithium battery prices all the way down, but for photovoltaic power station, the price of the battery pack + inverter current still account for about thirty percent of the total cost, and photovoltaic modules.

so many pv companies used to form a coalition, before construction to resist energy storage equipment.

solar panels, photovoltaic power station access costs?

another recessive cost of photovoltaic power station is access cost or interconnection cost, which is from the power plant to the grid transmission equipment costs. From the point of traditional power plant, general is responsible for power grid enterprise access. But the personage inside course of study tells a reporter, photovoltaic power station have generally assume their access costs. The personage inside course of study says, 'built needs such as power grid, power grid from planning to build is certainly need time, but not every plant into the power grid planning, so most of the situation to build first. '

access devices mainly include transmission lines and booster station, cost size mainly depends on photovoltaic power station site selection. Some main grid photovoltaic power station distance is further, you need one after another to build all kinds of booster station, the cost will be higher. Industry insiders said:

'interconnection cost probably account for about 5% of the power station construction, 3% - 10% of the cost, according to the condition of the plant's location and so on various aspects. Some lines are very long, the voltage level is very high, it will be taken into account. Also have very low, 1% of the cost, and location is particularly good, most is in fact about 5%. '

what hidden costs drop experts predict, energy storage cost pressure is expected to ease significantly in the future. China's energy chief information officer falcon, our country is battery power production and consumption, can through the use of cross-industry gradient, reduce the cost. Falcon said: 'the new battery installed in the car, when the energy storage efficiency is reduced, the scrappage, can take out the battery, we do use energy storage power station. '

access to reduce costs, in addition to rely on technological progress and increase of photovoltaic power generation project scale effect, more effective method is to strengthen the photovoltaic enterprises and grid coordinate. Falcon think, if both communicate in advance, as far as possible optimization of power plant layout, photovoltaic power generation will be more competitive. Falcon introduced: 'some companies over the years of cooperation between each other is not enough, so need to increase the merging between enterprises, establishing energy Internet, break the interest relationship of property right. By new technology, finally we can together, to increase the proportion of clean energy. ”
