Slow Factors of Target implementation for Distributed Solar PV Power

Solar PV power to alleviate the increasingly serious energy crisis and environmental problems has a great important significance. Although have a good prospects ,the policies landing are difficult, slow progress in construction is currently the status quo of the domestic distributed PV market.

Recently, in the helding IntersolarChina PV industry international forum, the national development and Reform Commission, Energy Research Institute researcher Sicheng Wang said currently distributed photovoltaic in China still faces seven big problems, low yields, qualified roof hard to find, financing difficulty, implicit transaction risk, access to the grid is not smooth, registration is imperfection and the long-term stability of the load restricts the solar PV industry development.

Currently, in China to develop distributed PV only have one road of "self-occupied", and the proportion of electricity account for 80%, at the same time the price of that building are higher.

Decided Our distributed solar photovoltaic power generation project benefit quality factors, are local sunshine conditions, power generation uses, installation cost, local subsidies supporting and local electricity charge. Thereinto, By regional factors which have significant influence are mainly the sunlight conditions and local subsidies supporting. The sunshine condition or that called sunshine long directly related to output. And differences in local supporting subsidies will be a big difference for the time of investment back

In this regard, the state is likely to be some adjustment of photovoltaic industry support policies, National Energy Bureau are discussing and researching distributed generation (DG) support policy adjustment scheme. Distributed solar photovoltaic power relations not only is the people's livelihood, but also related to national conditions, countries should utmost support. With the local subsidy policy launched successively, estimated photovoltaic power generation rate of return will be higher, large-scale off grid solar power system to achieve the goal will not be too long.

On the Roof of the Photovoltaic Business Opportunities, Chinese Dream

Recently, China lowered GDP growth triggered a lot of discussion, a lot of people on the Chinese economy whether is in the healthy operation of generating a lot of questions, even lose confidence in the future economic trends. In this regard, "Economic half-hour" deep into the first line of the socio-economic production, to present you the real Chinese economy. New energy solar photovoltaic power industry is considered to represent the new economy, but mention the photovoltaic industry and solar photovoltaic power generation, many people first reaction is this vocabulary of lower price competition, export-restricted and so on. If someone tell you, there will be a lot of families to install their own roof solar photovoltaic power systems in the future. Lying at home, not only can freely free use electricity, and even to use up the electricity sold to the national grid, do you believe it?　

First,Their power for their own use，rooftop solar power Supplying the national grid

Chunjiang Zhao is the director of Solar Energy Research Institute of Shanghai University of Electric Power, 2006 year he set up 22 pcs solar panels on their own roofs, built the first China personal home solar power station.

Chunjiang Zhao said his home solar power system is equivalent to a small 3 million watts of power plants, although compared to the hundreds of thousands kilowatts of large thermal power plants, it is very small, but his home solar power system is a very complete small power plants, from his home and sent to the conventional power plants firepower AC 220 volt power to issue and quality are the same.

As early as in a few years ago, Chunjiang Zhao is in their own roof built solar power station. 2012 years after he moved to the new home, then built a a new roof solar power station. Chunjiang Zhao said, in fact, family photovoltaic power generation principle is extremely simple: after the sun light irradiation, the series of solar battery assembly send out a DC power, through the inverter into 220V, 50Hz current can directly use. While the power equipment is particularly simple, only consisting of solar module, inverter, AC protection switch and a bidirectional ammeter.

Chunjiang Zhao believes that the future of these devices can be packaged together, like to buy a TV set, wait for professional personnel to install, we only need to calculate the site.

Family photovoltaic power generation cost is not actually high, Chunguang Zhao studied in Japan for many years, 2006 before he come back, Japanese family power station has reached 60 million. At that time caught up with Shanghai proposed 10 million solar roofs plan, annual household electricity in Shanghai hope to reach at least 330 million degrees. After returning Chunguang Zhao flew into RMB 120,000 to buy the solar power system components,. 2012 years he moved to Xinzhuang new home, also built their new photovoltaic system components and with the integration of the roof construction, with a total investment of only RMB 50,000.

Chunjiang Zhao now the solar power generator is 3.5 kilowatts, is theoretically per hour capacity will reach 3.5 degrees. Over the past year, this new system is generating more than 4100 degrees, his wife happily told reporters, now the home appliance use electricity casually, before the tank, air conditioning and TV is used with the mark, and now all opened. Before electricity need to be paid, in order to save one family all crowded in a room blowing air conditioning, but now no longer. She is feeling to feel the benefits of solar power, which makes their quality life has been a leap increase. In addition to their own home use, the remaining about 2000 kwh of electricity can enter the national grid. 

Chunjiang Zhao pointing to their own solar generator said, the weather is good today, now the power is 2500 kilowatts. Less than 11:00 has made more than seven degrees electric, today at least to generate 20 degrees, even are likely to 22-23 degrees electricity.

Now speaking of family photovoltaic power generation, Chunguang Zhao and his wife are smile, but 2006 when newly built home power plant, has attracted a lot of trouble. Remember when power station was built, the electricity sector were soon at the door, not to learn, but to send electricity payment bill. That had made Mrs. wife unhappy, she felt her husband lie her for their own power.

Because Chunjiang Zhao had promised his wife, installation home solar equipment, electricity almost don’t pay money. The power company who told them that electricity did not decrease, but also pay more than RMB 100 per month. Originally, this solar power system which electricity didn’t used up, then into the grid daytime. At night the station can not generate electricity, to get electricity from the grid. At that time, the power sector was one-way ammeter, unable to identify the direction of current, which causes both the current inflow or outflow, will be counted into electricity. That means more power generation, flowed into the electricity would be more ,so more payment. Moved to Shanghai Xhenzhuang new home, Chunjiang Zhao learned a lesson, directly to the Power Grid Corp apply for the installation of the bidirectional ammeter. 

Chunjiang Zhao, pointing to the bidirectional ammeter carefully explain to reporters, that when the meter display is the reverse active, means it is the outward transport power, is in delivering power to the grid. Now the reverse power is 0.05 kilowatt, home electricity is very large, TVU part are for home use, leaving only 0.05 kilowatt for outward transporting. Power reverse power is 2004.37 kW, the meaning is already to grid conveying the 2004 more electricity.

A little more than 2004 degrees, this is a total number of transmission power to Power Grid Corporation when reporters interviewed Chunjiang Zhao. If with their own electricity, then from 2006 to now, Mr. Zhao two sets of home solar photovoltaic power generation system, have a total generating 2.5 million degrees. The electricity in addition to the majority for home use, the rest have all been conveying into the grid.

Chunjiang Zhao said that before January 1, 2013, his two power plants generated the electricity are all free fed to the national grid. After, power grid company and he signed the network agreement, provisions of the electricity base price is RMB 0.4773 per kWh, but subsidies this piece has not clear. Although the power grid company year after year are talking about green electricity buyback, the price has not been finalized. Now the repurchase is not a problem, more important is to introduce a specific price policy. So, how much is the tariff exactly? Mr. Zhao is still waiting for relevant policies and implementation.

Beginning in 2013, Chunjiang Zhao whose home power also began to re accumulation, waited for the settlement. He also calculated an account, in accordance with the prices level of Shanghai, the investment a kilowatt of power plant is about 1.3 million, according to Shanghai sun's radiation, 1000 watts of annual power generating capacity is 1050 degrees, and the price of Shanghai should be set at about RMB 1.4, such 8 years could be guarantee recovery. Even countries bring the price down to RMB 1.25-1.3, 10 years can also be completely recycled. So, if the network price is the right, home power generation prospects are very broad.

Second,100,000 Solar Roofs Plan to implement Decade, Shanghai only six families to attend

Use the roof of home electricity, the remaining can send into the grid, but they did not think it would like to pay to the grid, Chunjiang Zhao embarrassing encounter were laughed by many people. 2006 Shanghai raised 100,000 solar roofs program, after five years the implementation of response was still a handful. Of course, that led to this plan failed for many reasons, the most important factor is easy to generate electric but hard to sell, but now the situation is changing. This year, March 19, Shanghai resident Jilin Chen from Power Grid Corporation got RMB 116, become the first person to self-built power plant in Shanghai to earn "extra money" .

Jilin Chen’s home power generation stations built in the third floor building on their own balcony, handmade wooden support above 11 solar panels, the panels are to be linked together, through the inverter to adjust and stable, the maximum output power is 2.5 kW and is 2.5 degrees per hour electricity. Mr. Chen told reporters that on and off grid solar power system device procurement were RMB 10000, plus the inverter assembly is total of RMB 15000, the cost is not high, now many families can accept.

Today, Shanghai's weather is cloudy, basically there is no big sun, in such a light conditions of power generation amount can reach 8.2 degree. If the weather is good, every day can send 15 degrees , every year can generate 2500 degrees. Remove their own electricity, the remaining electricity through bidirectional measurement meter input state grid, In this sense, Jilin Chen regard him as a supplier of power grid.

Then on March 26, Jilin Chen got the first sum subsidy from power company . The residents electricity balance sheet, is the collection of receipt display: Shanghai residents spontaneous self power the remaining send into grid which electricity settlement price standard temporarily is RMB 1 kwh, waiting for the relevant state policy clear, approval in accordance with the national Internet price to liquidation, retreat more fill less. Mr. Chen told reporters that contract temporarily according to the benchmark price, in fact, execution is by RMB 1 kwh because the power grid companies have no right over desulfurization benchmark electricity price contract on display, then they gave him fill RMB 127 price difference.

Get RMB 1 per kWh on-grid power tariff, Jilin Chen saw an opportunity, he told reporters that such a tariff, seven years will be able to recover the full investment, the life of photovoltaic power plants are more than 25 years. He gave his family a calculation, in previous years, a year in use electricity at home are about RMB three thousand, now his family installed a 2.5 kilowatts of photovoltaic power generation device, a year the basic unit of electricity can generate 2500 degrees, that is probably income RMB 2,500, can offset each year to pay RMB 3000, he can save 70% of electricity annually.

Now, Jilin Chen are intending to put the unused roof to install solar panels, expanded 2.5 kwh power to 3 kilowatt hours. So in addition to their own electricity were available, the annual power generation also make some money. He felt under this policy remains unchanged, this model can also be continuously replicated copies. He pointed to the nearby villa roof said, now there are a lot of empty roof, to install solar power system for electricity on the roof which market potential is huge

What Kind of Distributed Solar Photovoltaic Roof are Most Valuable

" Solar PV power industry next era should be called 'pro-roof resource is the king'." Co-director of Hangyu Technology Co., Ltd. (hereinafter referred to as Hangyu energy) Yang Liu believes that the scarcity of resources is the pain point of industry development, who will occupy the first chance who can solve it, and the future PV market will not lack of polysilicon, nor photovoltaic modules, but the roof. 

His judgment is based on an industry consensus: China's distributed solar PV market is heating up. The so-called distributed photovoltaic, usually refers to small-scale photovoltaic power generation system( off grid solar power system) is installed in home or residential commercial and industrial rooftops, courtyards, to the owners of self-occupied, remaining electricity access to the grid operation. In the photovoltaic market started earlier in Europe and America, it is the main way of distributed photovoltaic solar energy utilization. Nearly nine out of Germany from distributed solar photovoltaic power generation system, the number of family homes roof power plant over one million; Last year the United States added new distributed photovoltaic power generation capacity has reached 2.2 million kilowatts.

In China, large-scale centralized ground station is still the main way to achieve solar photovoltaic power generation. Up to 2014, China PV cumulative installed capacity of 28.05 million kilowatts grid. Among them, the ground station are 23.38 million kilowatts, only 4.67 million kilowatts of photovoltaic distributed. However, in view of land resources, the ability to send power grids and national subsidy financial pressure and many other constraints, many people in the industry have expressed similar views to the author, that the development of the ground station will gradually slow down over next three years, and various distributions the formula will be the development direction.

 

"From an investment point of view, the ground station can last two or three years." In the GCL New Energy Holdings Limited (00451.HK, hereinafter referred to as GCL new energy) in the photovoltaic power generation project investment Shanzhong Zhang think that, PV application market the determining factor is financial leverage. "It is a hot point of ground station, at their own expense by 10%, someone take 90% to capital. Although distributed project now unable to do, all the bad factors will improve over time. We look for the market will be forced to the roof.

With more and more enterprises and funds investing in distributed solar photovoltaic, roof, especially those who are most power and profit potential high quality roof, just as land is becoming parties to compete for the subject. But what kind of roofs are most valuable?

 

Big business Roofs are rarest

Since human Jielu to live, the roof is not new things, but people take it from the photovoltaic various grades and ranks

"Duddy, I have roof resources, let's look at?" this is Yang Liu the most afraid to hear words, because many people mistakenly think that the "roof" is equal to "project". And for professionals, choose roof as like choose beauty.

Economy is the primary criterion for evaluation rooftop PV projects. Roof, whose owners units best are the stable operation and strong big power to the roof. High energy consuming owners to install distributed solar off grid system, to achieve to  maximize the economic benefits of the project. National policy to encourage power users in accordance with the "spontaneous use, grid allowance" approach to building distributed photovoltaic power generation system. The NDRC price department 2013 No. 1638 documents stipulate, to distributed photovoltaic generating electricity subsidies policy, subsidies standard is RMB 0.42 per kilowatt hour; Among them, occupied the remaining power grid, by the power grid enterprises in accordance with the local coal-fired units benchmarking Internet acquisition price.

If business owners can use all photovoltaic self-occupied, it will be the largest economic investment. Because according to the current policy, self-occupied part of the earnings-per-watt is equal to the original unit price of electricity plus state subsidies RMB 0.42, while the online portion of the earnings power more than just benchmark electricity price increase state subsidies, currently around commercial and industrial electricity prices are far higher in feed-in tariffs.

But the scale of development is another important index to distinguish the quality of the roof. The scale 1 MW project compared with 5 MW project, two pre development costs are basically the same, investors certainly love big roof project.

Different Geographical position can also delete a large part of the roof. PowerOAK family photovoltaic a person in charge told reporters, the current domestic suitable for large-scale development of distributed PV provinces are rarely, one is in the provinces of Shanghai, Zhejiang and other places have high subsidies; the other is the local power supply tension leads to commercial and industrial electricity prices high provinces, such as Guangdong.

Therefore, in the eyes of distributed PV developers high quality roof need to contain the following characteristics: owners stable operation and high power consumption; long period existence of roof; suitable for developing more than 5 MW large roof solar power station; high local subsidies or local industry and commercial with high price. Accord with above standard of roof resources are very scarce. "Most of the best roof are state-owned enterprises, central enterprises and large listed companies, small private enterprises dare to guarantee stable operation of 20 years is not much, not to mention the meeting other conditions." an investment industry sources to the author said.

The roof of various grades and ranks

Small area roofs, solar photovoltaic power generation can provide attractive business owners inherently inadequate. These roofs can try to re-rent pack make up large projects. PowerOAK is doing that.

From the perspective of the economic benefits investment, the small scale roof still does not have the attraction. For example, IKEA Beijing Quaternion Bridge shop which roof power station the annual average generating capacity are about 30 million degrees, barely enough to meet the market 80% lighting power supply system, the entire Mall consumption is a drop in the bucket. But similar like IKEA companies test photovoltaic roof, even more to see solar PV power as a green energy behind the concept of environmental protection, which to boost corporate influence, shaping a good social image have a positive effect.

There are some people in the industry believe that only a small rooftop distributed PV on behalf of the trend of development. Yang Liu predicted that, in five years distributed PV market will be hot competition for resources roof scale 1 MW or less.

This judgment from foreign experience in the development of photovoltaic PV market, has always been from easy to difficult, from the depth of large-scale to small-scale distributed . But China’s situation is different, the small roof era needs more time. The current trend is visible from the scale effect was significantly depleted but soon developed a large-scale ground station resources to the same large-scale distributed projects. To distributed project about large-scale agricultural photovoltaic project Zhang Shanzhong told the author that large-scale agriculture, fishery and photovoltaic complementary projects, can extend large-scale ground station investment heat 1-2 years. Such projects currently classified as distributed, but its construction business model and business investment model and the large ground station is not very different, are the grid, with full electricity sold to the grid, obtained subsidized price revenue. This kind of distributed project business model are relatively mature, easy to attract investment. 

What Does Distributed Solar Photovoltaic Power Generation System 150MW Mean?

Recently , someone have ask me "What does distributed solar photovoltaic power generation system 150MW mean?" OK, now let me tell you something about it: Distributed solar photovoltaic power generation system 150MW means a total capacity of 150 megabytes of tile type solar power station.

Distributed solar photovoltaic power generation systems in particular are constructed in the vicinity of the user sites, operation mode to the user side of spontaneous self-use, excess electricity send to the Internet, and in the distribution system to balance the characteristics of photovoltaic power generation facilities.

Distributed solar photovoltaic power generation to comply with the principle of local conditions, clean and efficient, decentralized layout and nearest use, make full use of local solar energy resources, replace and reduce fossil energy consumption.

Distributed solar photovoltaic power generation refers to the use of photovoltaic modules, directly convert solar energy into electrical energy distributed generation system. It is a new, with broad prospects for development of the power and energy comprehensive utilization, it advocates principle of the nearest power generation, nearest grid, nearest conversion and nearest using, not only can effectively improve power output of photovoltaic power plants of similar size. At the same time, also effectively solve the power in the boost and long-distance transport loss .But sometimes people usually take the smaller portable solar generator for the outdoor activity, because of small and convenient to take.

At present, the most widely used distributed solar photovoltaic power generation system, is built on the roof of the city's photovoltaic power generation projects. The project must be connected to the public grid, with the public power grid get together for the nearby users.

What Is The Difference Between Solar Thermal Power Generation and Photovoltaic Power Generation?

What is solar thermal power generation ?
Solar thermal power generation is a new type of solar power generation, generally we said the solar power generation refers to the solar photovoltaic power generation, which are two different ways. That is to say, now solar power system has two ways, thermal power generation and photovoltaic power generation, its operating principle and the use of the scope are big different. Solar thermal power generation also called focus solar thermal power generation, unlike photovoltaic power generation, it is through a variety of physical way to steam solar direct light together and produce high temperature and high pressure steam to drive a turbine to generate electricity. According to the heat collection in different ways, can be divided into three types:  trough solar thermal power generation, solar tower thermal power generation and solar disk type thermal power generation.

The difference between solar thermal power generation and photovoltaic power generation

Firstly, generation principle and device are different.Solar thermal power generation is through the heat collecting device to drive the turbine power generation, which is heat transfer to electric, the main components are collector or device; while photovoltaic power generation is using light of a semiconductor photovoltaic effect to convert sunlight directly into electrical energy, the basic component is solar panel, which is light electricity conversion.

Secondly, the using scope is not the same. It has a better fit for solar thermal power generation electricity and the traditional thermoelectric, water and electricity, suitable for large-scale development.

Also , due to thermal power require higher light, it is more suitable for light which the area in very good condition. And photovoltaic power generation device is relatively simple, to light requirements is relatively low, more suitable for development of miniaturized, therefore, it is more suitable for distributed using.

At last, for specific using, photovoltaic power generation has formed industrialization, use technology more mature, suitable for a wide range of popularized using. At present, thermal power generation still in research and demonstration stage, the cost is also in the high level, the large-scale application also need more time. Recently, China's first solar thermal power generation station have generated electricity successfully, which is national investment construction.

Therefore, at present, the average family in the choice of solar power system does not have to consider the solar thermal power generation.

Why choose solar photovoltaic power generation

Written by Sarah Hwong ,Jan. 5,2016

Recently , Solar photovoltaic power generation has played an important role in the world . Why do I say that ？Please see as following reasons:

With the development and utilization of coal and other conventional energy resources, traditional fossil are exhausted day by day. But the demands of energy sources for social development are increased gradually. Energy supply contradiction are more and more prominent. People have to face the result of environmental pollution problem .  limited resources are shortage, the costs of power utilization are increased, too.

Investment to the solar photovoltaic power generation, not only directly make a great contribution to saving the social resources and reducing environment pollution, but also lock up more than 20 years lower electricity prices to obtain stable power generation income.

Your choose is not only one high return without risk and have plenitude guarantee investment for the future benefits,

But also make an effort to global Carbon dioxide emission reduction

Saving is not only electricity cost 

When your solar photovoltaic power system start to generate your own electric, it has reduced the operation expense from the first day. Your each month electricity charge bill will be a great lower. With the growth of time and utilization, and electricity price constantly increased, every year you will save more. It can reduce each month resources expense, and promote your family efficiency , comfortable and healthy. To use solar power system also can promote your energy consumption efficiency ,you can check the past using situation of electricity and gas, solar power generator can help you reduce the energy consumption, and save the power expense. The government’s electricity price subsidy police can help you gain more benefit, the roof will be your own bank ATM. 

To protect our homeland together 

It is very rich of solar energy to illuminate on the earth surface, about 40 minutes solar energy, enough to provide one year energy consume for our human being. So please joint us today, you can start a small solar photovoltaic power generation ----- portable solar generator, let us protect our homeland, to create a more clean and effective environment for the survival and development.

Can the solar power generator system be sustained if there is no government support ?

Written by Sarah Hwong ,Dec.30,2015

Recent years home solar power generator system have been

an unprecedented development in many countries, a big reason is benefited from various forms supporting of government subsidy policy. 

For example, the United States is to install rooftop solar         power systems users for directing subsidies costs.  While in many other countries to implement on-grid repurchases policy,which is national to acquire scattered electricity generated by the solar power generation system, this is also equal to           subsidize the cost of installation. Whereas , as all known        policy is stage.  If there is no government policy support,
household solar power  system can be sustained?? Which had caused industry concerns.

Australia is a country with much land and few people, to develop the rooftop solar photovoltaic power generation market will be more meaningful. Although the country's solar power generation applications started relatively late, the solar power installed capacity have reach 785MW by 2011. which are mostly used in residential and commercial buildings. It has become the largest market for solar roof installation in the world. 

In order to accelerate the development of solar energy, Australia solar energy industry also hope the government can give policy and financial support. However, the result is more frustrating, the Australian federal government announced in November 16th, will end the house top solar panels in January, 2013. The subsidy plan ahead of schedule for 6 months, in any case that makes the whole industry more worried.

   

Now we have to face such a problem, after a series of government subsidy policy, is there any feasible way to promote the development of solar photovoltaic power generation??  Without the government support, solar power system requirements can be continued? It needs more time to prove.

 So far , individual solar power generation system  still does not have the cost advantage. But with the solar energy utilization technology continuous development and progress, will also promote the solar energy utilization.

What kind of family is suitable for solar generator systems?

Writen by Sarah Hwong,Dec.30,2015

With the implementation of a series of domestic photovoltaic policy, many families can built solar generator systems to give their own power. If consider the cost factor, not all families are suitable for installing the solar photovoltaic power generation equipment.  

Whether using solar photovoltaic power generation can save electricity costs for households, this is not absolutely . It needs to according to actual situation of the household electricity using. Investing in solar power is not an absolute number, but depends on the household electricity costs are measured by the cost.

Generally speaking, household consumption is more bigger, more suitable for installing solar home power systems equipment, investment time of cost recovery is shorter. Secondly, the more proportion of electricity at daytime , the more suitable for installation of solar power generation equipment.so there is a small processing plant of the family, shops will be more suitable for installing and using it. The little electricity, especially little use during daytime, these families are not suitable for installing solar power generator systems. because initial investment is a little big. Long-term benefit of power generation projects, regardless of power system capacity is large or small, there is a higher initial investment cost. In the long term, although it is a save a electricity costs project, not all families are willing to bear the initial installation cost .

For home or outdoor areas without electricity, I think they can  install off grid solar generator systems equipment. As the investment cost is several times higher than normal electricity’s,  unable to use normal standard to measure the electricity expenses. Therefore, home or outdoor areas without electricity are not suitable for large-scale power generation equipment investment, but portable solar generator equipment will be a better investment way to solve the basic problem of electricity.
