Solar Power System to Meet the National Conditions of the Highlights

A development of industry don’t be separated from consumer recognition and affordability, take solar power system why is popular in Europe, the main factors is the states pay more attention to environmental pollution governance, and through the attractive subsidy policy to encourage the public to recommend the solar power market application. Second is European residents whose villa residential environment with available resources. 


Nowadays, solar power system have been gradually hot up in the domestic, the resource and environment of the domestic photovoltaic, most development potential of the highlights are family and distributed solar power generation, the two forms does not need too much capital investment, the ordinary family general in the economic can bear, and the government will continue to increase subsidies for solar power for light , from the point of view of distributed solar power system to a number of small and medium-sized enterprises is quite attractive, idle workshop roof and factory can make good use of, although cannot solve a large number of industrial electricity, lighting electricity also can save a lot of cost.


It is reported that the developers for the future real estate development will be reserved the installation of solar power generation equipment, every household in the future are likely to use their own solar power generation system.

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

Establishment of Hsinchu Solar Photovoltaic Driven Group In Response To the New Government's New Nnergy Policy

Another local government of Taiwan declared investment new energy development. Recently, Hsinchu city council has approved < City pipe public houses set solar power system standard rent management measures >, will be the city set up solar driven group, assist the private sector with solar power generation system.

Hsinchu is Taiwan technology R & D and production center, many solar companies stationed. Hsinchu Mayor Mr. Zhijian Lin said, 2015 Taiwan  solar photovoltaic output can be the contribution to GDP of NT $15.3 billion, but production products really have 97% export. In the new government shouted 2025 installation 20GW solar, 2025~2030 non nuclear homes, the local government must be stepped up to put forward the corresponding policy, and jointly promote the development of solar energy, to reach the goal.

Through the establishment of new regulations, Hsinchu Government will be able to more efficient use of the city under the jurisdiction of public buildings, promote solar and other renewable energy development. At the same time, the city will actively contact solar owners, organized seminars and start tutoring mechanism, to help people use solar power generation system. Mr. Zhijian Lin said, Hsinchu City " to promote solar photovoltaic group " by all at the main responsibility, meets regularly to review the progress, and view the initial results. After 24th standard rented premises by the public way, related work will start as soon as possible.

In the future with the release of state-owned land, to create new energy industrial ecology of the new government policy, Taiwan off grid solar power system industry each year is expected to be 15-20% growth. As a science and technology center in Hsinchu also hope through the implementation of the policy in place, using their own industry niche, for the city and the public to create a better living environment and economic development.

WTO: India Solar Energy Localization Policy Violations

In recent years, India is committed to promote the development of solar energy, including target in 2022 will develop 100GW solar power generation equipment, encourage overseas capital into India, and India local companies established local enterprises to supply the required services and products. Among them, Indian Planning Exhibition procurement restrictions, but WTO found to violate the principle of Global trade, and India lost.

The times of India reported, Indian Prime Minister Modi shouted slogan "make in India (India)", the purpose is to support local industries. However, because India often to protect the domestic industry and for overseas products proposed anti-dumping duties, or limit components of local procurement ratio etc.,which is suspect for violation of the principle of fair trade. Contains solar industry, is also required to sell electricity to the government of the solar power system plant in hydropower development,battery and procurement of components must be a certain proportion of production in India

The United States government believes India's policy have violated WTO Global trade principle, and in 2013 put forward accuse; Taiwan, Mainland China, Brazil, Canada, Japan, South Korea and other countries also joined the third member filed a complaint. Last year WTO had condemned India loses, but India had appealed; After appealed, a few days ago WTO the second sentenced India loss, India still has to appeal within 60 days, or change the existing policy.

Africa Solar Football Stadium Can Also Power Generation

Facing the renewable energy to provide unlimited possibilities, Africa has been awake, the African Union will invest $200 million for these solar power system in the next ten years. In East Africa, according to the need to buy solar service has gradually become mainstream. In West Africa, everything is still in the experimental stage. More characteristics of the test project is one of a solar football -- apart from solar outside, it can use playing football to generate kinetic energy.

The solar stadium is Located in Lagos, Nigeria's commercial capital of a normal university, is the product of the tripartite cooperation -- energy giant shell, is committed to promote solar energy in Africa of American singer Akon (Akon), and will provide Africa low cost renewable energy power solution set as the important goal of British companies Pavegen.

This is the world's second off grid solar system stadium, the first built in Brazil in 2014. The most interesting place in the stadium is that it is not only use solar energy, also use kinetic energy.

Pavegen technology is to use ball-park "tiles" to capture the players coming from the kinetic energy, for this reason to generate electricity. This energy is sufficient to meet the low voltage system, as like street lamps demand can also store up power for later use.

Not only solar energy generate electricity, can also play-consuming physical solar energy into electrical energy not only generate electricity, but also can play consuming physical energy into electrical energy

Under Ball-park turf there are 100 pieces of these special "tiles", get their energy from the movement players. Total generating capacity of the kinetic energy and solar panel can ensure the community 24 hours street lighting.

More play, pavegen generation technology are more and more, is not difficult to imagine, this technique is actually most suitable for many people of the area, such as schools, sports center and market. Company founder Campbell - Cook (Laurence Kemball-Cook) introduced said, solar power stadium just to show people some possible.” The project tell us, the future energy to how the blend morphology, solar energy and kinetic energy can bring what kind of improvement to our community.” "

Their off grid solar power system stadium approach clearly provides a possibility to solve the power problem in Africa, but to really reach the goal, must also find a way to mass production, and to achieve the balance in terms of cost.

Morocco To Build The World's Largest Solar Power Plant

February 6, according to TheVerge website reported, Morocco on the edge of the Sahara desert town Ourrzazate established a huge solar power system plant. The plant cover thousands of acres, can produce up to 160 megawatts power, it has already been one of the world's largest solar power grid, from the sky will be able to see and the plant will only become more and more large.

The named for the grid of Noor I is a project of the first phase , the project objective is to live in Morocco and millions of people to provide renewable energy. Soon will expand to Noor II and Noor III, and add more mirror in the existing power plants. Once the project is completed in 2018, the grid will cover 6000 acres, at that time will produce up to 580 MW power which can comparable with that of a small nuclear reactor.

At present, the entire solar farm is made up of 500000 pieces of curved surface mirrors, each mirror is about 40 feet high. These mirrors gathered sunlight to a fluid filled pipe, and the liquid is heated to 739 degrees Fahrenheit (393 degrees Celsius). The liquid is used for heating a near headwater, which into steam to drive a turbine to rotate to generate energy. In Morocco every year has about 3000 hours sunshine, so there is a lot of solar energy can be used. But the plant can also be generated electricity at night, "liquid heat can be stored in a box filled with molten salt water tank." NASA wrote.

According to the guardian said, the current Noor I can from dawn to before sunset about three hours for 650, 000 local residents provide solar power. After completion of the power plant a day can provide 20 hours electricity. This is one of Morocco's plan, the plan will from renewable sources of energy, such as solar energy, the wind and hydroelectric generation acquired power about 42% used for household. Now the whole countries, 97% energy consumption are depending on imports. The new on and off grid solar power system plants and can reduce the dependence, in the meantime will reduce Morocco millions of tons of carbon dioxide emissions.

Ali Fassi Fihri, Morocco, president of the national electricity and water companies said at the same day, from 2016 to 2030, the friction will invest about 280 million euros in the development of solar, wind and hydropower projects, these new renewable energy projects installed total capacity for 10 000 MW.

Moroccan is lack of traditional energy, 2009 formulated renewable energy development strategy, to encourage private capital investment in the construction of wind and solar power system generation station at home and abroad, plans to 2020 will be renewable energy accounted for the energy consumption of the proportion of the total up to 42%, in 2030 reached 52%.

Marine Solar Power Station

Marine solar power system station can solve the lighting problem in the night at sea, it mainly consist of the solar battery board, a storage battery and super bright LED lighting and universal USB data line. Solar panels by absorption sunlight and solar energy conversion into electrical energy stored in batteries, to prepare for lighting or a variety of mobile equipment charging.

Advantages of marine solar power station:
1. Safe and reliable, no noise, no pollution emissions.
2. Solar energy is inexhaustible, unlimited use.
3. Marine solar power station to reduce costs, no need to consume fuel and erection of power transmission lines that can be in place to generate electricity.
4. Don’t subject to geographical distribution of the restrictions, any need for electricity can be used in the area of solar power generation.

In a word, if there is a solar power generator system in the ship, it will be more convenient to do anything in the night.

Vietnam's First Solar Power System Plant Have Been Constructed

On Aug 29.2015, located in Vietnam's Quang Ngai province a 19.2 megawatt solar power system station to be started building. This is Vietnam's first solar power plant ,which is expected to put into operation to generate electricity in July next year.

The solar power system plant costs approximately $ 36,120,000, will be an annual output of about 28000000 kwh of clean electricity to the main power grid. Solar power plants will be imported from Thailand's solar panels.

Earth encyclopedia noted that nearly a quarter of Vietnam's energy consumption comes from oil, and the remaining 10% is supplied by hydropower, coal accounted for 20%, natural gas accounted for 11%.

So far, Vietnam's solar energy development is relatively slow. The encyclopedia said, by the end of 2014, Vietnam installed capacity of up to 3600 kilowatts, of which are about 15000pcs small PV off grid solar system applications.

Solar Power System Have A Unique Style Of Business Management

Nowadays,to install household solar power system to supply have been many foreign family intention to choose, but there is still exist large problem , initial installation cost is too high, so that many families can not be expected. Therefore, if we can reduce the cost of initial investment, there will be more family can be more easily used on solar power generation system. And in foreign countries, operating a solar photovoltaic power generation company launched a unique way to attract customers.

The company have engaged in the sale of solar power system more than three years, they always have been looking for more scheme selections for customers to accept, such as produce the small device—portable solar generator, but the final choice way is a lease. This way allow home users advance payment some rent then can use their products, and they can also charge a fee from the system maintenance and repair work.

From the operator's point of view, using the lease can attract more users , can rapidly increase the turnover ,to occupy the market rapidly. While from the user's point of view, first of all, they can pay the lowest of one-time inputs cost to use solar power system, don't worry about the daily maintenance and repair work; Secondly, because of the power buy back policy, the electricity generated can sell to the public grid, you can also earn some electric charge. Therefore this mode of operation by the users are welcome.

However, the biggest problem is requires large capital investment, that is to say, should have been borne by the user of the high initial cost to the operator. So it is necessary to have strong financial strength is likely to be used in such a way to operate, there is no doubt that this is a helpful to more families use solar power system model. From all solar photovoltaic power generation market , it is more and more popular to install solar off grid system at the roof ,perhaps this will bring large consortium entered.

The Development Of Solar Energy Technology Is Not Limited to Production Innovative

Make great efforts to improve the utilization of solar energy technology is to improve the solar energy utilization efficiency and reduce the cost, the development of this technology should be made in the field of production and consumption. In production field ,in improving the photoelectric conversion efficiency of the solar battery board and improve the inverter conversion efficiency, off grid solar power system also need to complete the energy storage device. 

As reported, there are American scientists have invented a kind of transparent solar cells, with higher photoelectric conversion efficiency. But on the whole, in today's industrial scale, products technology temporarily failed to achieve a breakthrough in the production field.

With the rising of the consumer market, this is the other field which can seek to increase the utilization technology. Running stability is an important factor which impact solar power system cost, this stability not only depends on various parts of the excellent quality, but also depend on the overall operation of the system. For example, currently a lot of distributed solar power generation system incorporated into the public grid, there are many problems, these problems directly affect grid solar power whether can be greater room for development. These may be requires that the state power institutions to study the problem.

At present, In United States has research projects about solar energy prediction technology, the purpose is to predict the solar power generator system when and where can generate how much electricity ,to optimize the grid structure and easy to debug, thereby reducing the cost of solar power generation system access, promote the use of solar power generation technology.

The Component Part And Function of Off-grid Solar Power System

Off-grid solar power system is a completely independent of the existing power grid, it can also be used in remote areas. Whether stationary or mobile home solar power system equipment, its components are substantially the same, including solar panels, batteries, solar charge controllers and solar inverters. According to the requirements of size and function of the required system components are also different.

One: Solar panel
The function of the solar panel is to convert light energy into electrical energy, which can absorb light and directly generate direct current. After connecting the power supply line, the DC power can be stored in the storage battery in the way of chemical energy.

Two: Storage battery

Battery is the electric energy storage device, through the way of electric energy into chemical energy to storage the electricity generated by solar panels. In the needed of using electricity, can be released from converting the chemical energy into electricity.

Three: Solar charge controller

Solar charging and discharging controller act as a central hub, control and regulate the working state of the solar power system, and played a protection function role of the battery overcharge ,over discharge. Place in a big temperature difference, the qualified controller should also have the function of temperature compensation. Other additional function such as optical switch, control switch should be controller’ optional.

Fourth: Solar inverter

Direct output voltage of solar power system in general are DC 12V , DC 24V, DC 48V. For AC 220V load appliances to provide electrical power, it need DC power which is generated from the solar power system to converted into AC 220V or AC 110V power. Therefore, it must use the DC-AC solar inverter. which function is to increase voltage, and the device that converts alternating current to direct current.

In the actual process of the specific installation of solar power system, according to the size of the power system can also need to configure additional components such as junction box. And in order to ease of use, all-in-one solar power generation equipment is a good choice, for how to choose a suitable mobile home solar power equipment--- portable solar generator, all above parts are very important reference factors.

Field Force

Communication command power supply:
Army field training, geographical condition are very complex, the training situation are changing quickly. The command department often only through radio get in touch with training troops. Make sure that the command center reliable supply of electricity, is the premise of the normal operation of the station. This plays a crucial role for the command center in time to see live images of training troops, get training site exact geographical location, to understand the field training and timely command scheduling .

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.
