Cixi days and homes have built the country's first residential photovoltaic power station, at present has been running for 7 years, the power for small basement lighting, spare part into the national grid. Reporter Zhang Mingming perturbation
Yesterday, Cen Shaogen of 57 years old Cixi farmers around his greenhouse in a circle.
The steel structure of the greenhouse and other greenhouse is different, the top and the surrounding installed solar photovoltaic panels, greenhouse power required, provide for oneself completely, and the remaining.
Cixi Electric Power Bureau staff to view at the scene yesterday this set of photovoltaic power generation system, access network scheme of it. Soon, the old Cen solar power, the excess part can be sold to the national grid.
Also yesterday, Ningbo Electric Power Bureau staff came to Beilun, Mo Zhikai home, guide the grid-connected ready for him. If successful, his home solar next month will formally grid-connected power generation. Mo Zhikai will become the first people in Ningbo with solar power.
"Home of the solar energy equipment, if in the summer, the monthly electricity 1000 degrees, I simply could not finish, this is great, can be sold to the country." Mo Zhikai said.
At present, all of Ningbo's clean energy (including wind, solar energy) power is less than 0.1% of the total generating capacity, so the electric power department is also very much hope that the promotion of clean energy power generation.
Love fashionable Cixi farmer old Cen
1600000 to build solar power station
Cen Shaogen is a native of Cixi farmers, 14 years old started to do farm work.
Only primary school culture he, special love study. For dozens of years, cauliflower breeding research and let him become the agricultural famous, now he is Cixi City Shaogen vegetables professional cooperatives chairman.
"I don't have much culture, but particularly fond of high-tech."
Two years ago, Cen Shaogen learned to communicate with the leadership of Cixi agricultural greenhouse may have photovoltaic power generation, countries have subsidies, the excess electricity can also sell.
"The earth out of things to sell, so the sun light can also be sold." Cen Shaogen was very moved, decided to give it a try.
Agricultural cooperatives in Cixi Cen Shaogen Xiaolin Town, the existing 508 acres of land.
Two years ago, he decided to spend a large amount of money to build two high-tech agricultural greenhouse, two of the total area of 4224 square meters, Cen Shaogen called it a "photovoltaic and photothermal agricultural greenhouse".
"In a word, everything is automated." Cen Shaogen said.
Reporters yesterday at the scene, the two in the East and South used 121 pieces of amorphous silicon solar panels, roof has 228 pieces, the total cost 1630000 yuan, plus the wisdom of agricultural system, the total investment reached 2450000 yuan. The Ningbo and Cixi two financial subsidies 1200000 yuan.
Solar photovoltaic panel consists of monocrystalline silicon, polycrystalline silicon and amorphous silicon, the former two occupy most of the industry as a whole. Amorphous silicon is less in quantity, free cutting, made of very thin film is very thin, has good application.
Last October, Cen Shaogen's "photovoltaic and photothermal agricultural greenhouse" built. But the state has not yet introduced policies to accept photovoltaic power, his photovoltaic power station can only choose "off-line power".
Off-line power means that the photovoltaic power generation all through the battery storage. In power distribution room, the reporters saw 22 batteries feet, five or six square meters big. These batteries need to be replaced every few years, lead battery itself also has certain harm to environment.
"The best way is to power generation, to use it, to take power from the power grid." Cen Shaogen said.
In the distribution list box, the reporter saw at present the system has been accumulated generating 4734 kwh. According to estimates, this set of photovoltaic power generation system annual energy output of around 36000 kwh.
"I this two greenhouses, an annual output of about 1500000 yuan, the photovoltaic devices are for breeding services. Relying on solar power to make money I never thought." Cen Shaogen said.
Yesterday, Cixi Power Bureau staff in the field survey, back on his last admission scheme. The staff said, here from the power grid is far, either from a distance to wiring, or installation of transformer in the vicinity, inverse into high pressure on the internet.
"In the end how to get, need to Ningbo Electric Power Bureau to decide." Staff said.
Beilun Mo 300000 to build solar power station
Can sell electricity to the country immediately.
Mo Zhikai this year 27 years old, is engaged in the foreign trade occupation, the son just 6 months. Five UNITA village, he lived in Beilun Creek, a large open space in the central courtyard, Mo where built a can park 6 cars in the shed, shed top, neatly 24 solar photovoltaic panels.
This is just a small Mo "small power station" a small half, the top two balcony on the top floor of the villa, with two rows of solar photovoltaic panels, all together, "small power station" a total of 70 pieces of solar photovoltaic panels, the output power of 7.5 kw.
Mo said: "this set of solar photovoltaic panels have been installed four years, when my dad got the idea, the future solar photovoltaic panels power, their own homes don't finish, also can be sold to the national grid."
Compared with the ordinary people, little mo home installation of photovoltaic panels more advantages, little mo father is engaged in solar photovoltaic panels production. "At that time from the factory for 70 pieces of plate is worth about about 200000, and other ancillary equipment, and spent a total of about 300000." Mo said.
However, little mo this small station building has not put into use. Little mo explained: "at the time of installation, countries are not issued to encourage individual grid-connected power policy, if the use of this set of equipments in power, only two way: one is the grid-connected power generation; two is to buy batteries."
"The role of the battery is the power collection of Bai Tianfa, and then to the stability of the alternating current, for home use. But the battery cost is too high, the solar panels use period is generally 20 years, and the battery life is only two years, equivalent to I have to change 10 sets of battery with solar photovoltaic panels, this calculation, the cost but also increase 200000, think of uneconomical, is idle."
Yesterday, after careful study of little mo Jia Li, Ningbo city power economic and Technological Institute of technology staff Sheng Faming said: "the installed capacity of his family and the installation position is no problem. Next we will communicate with him in power in actual conditions, after 10 working days, make a access for him. He just follow our advice to the operation, we can immediately grid-connected power generation."
Little mo solar power station because no enjoy state subsidies, sold to the national grid price 1 yuan once, "count down around 10 years can recover costs." Mo said.
How do the installation of solar power
Device where to buy about how much money to spend
Yesterday, the reporter search "household solar photovoltaic power generation" in Taobao, show a total of 602 commodities, with solar panels, single crystal, polycrystalline have, and solar power suit, home power calculation software.
The general manager of Ningbo Fengshen Wind Power Group Limited assistant Du Shangbin said: "the solar wafer is divided into single crystals and polycrystalline, from the conversion efficiency of the solar terms, single crystal than polycrystalline slightly higher, while prices slightly, single crystal. But for ordinary people, little difference and buy the single crystal or polycrystal."
Solar photovoltaic panels placed on a roof in the event of a long-term, typhoon, torrential rain, snow, or bird droppings do? Du Shangbin said: "in the photovoltaic panels above, there is a layer of tempered glass, play a protective role, if not intentional damage, general typhoon, rainstorm are not affected, basically do not need maintenance. Photovoltaic panels covered with dust or guano will affect the efficiency of light energy conversion, rain will wash clean. If the snow, snow covered photovoltaic panels, is temporarily unable to power."
Then, solar photovoltaic panels should be where to buy? Mo said: "Ningbo has several specialized production of solar photovoltaic panels, if you want to buy, I suggest or directly to the factory consultation, online shopping is more reliable than. However, due to the individual installation market is too small, some manufacturers have basically no straight camp shop, to buy up may have some difficulty. If you have to go online to buy, attention should be paid to merchants can provide product inspection certificate, product to get the attention of photovoltaic panels, the back of the 'total watt voltage, number, manufacturers' information is complete. In general, 1 kW photovoltaic panels licensed in the price of 20000 yuan."
As long as the purchase of photovoltaic panels, the installation is very easy. Mo said: "as long as the election of a day of sunshine for the longest time place, install the best angle of photovoltaic panels and sunshine into a 90 degree angle, and the ground was 30-45 degree angle. When installed, according to the specifications as long as can be, and do not take the wrong, very simple. The welding bracket can ask professional help."
Since the power system in addition to the solar panels, but also with the inverter, the power can not be less than the solar power inverter.
In addition, the installation of solar photovoltaic panels must be installed to prevent lightning rod, plate by a bolt of lightning.
Yesterday, Ningbo City Power Economic Institute of Technology Technician Sheng Faming said: "solar energy is clean energy, we are very supportive of the. But there are also disadvantages, power to the sunlight is limited, with the change of the weather, power generation capacity at any time in the wave, while the State Grid demand is stable, so in before, must make some modification of the user, in particular we do guide."
Personal photovoltaic countries purchase price is about 1 yuan / degree
Enjoy 0.5 yuan acquisition of state subsidies
In 2012 October, the China State Grid Corp announced its acceptance of 6 megawatts below the distributed grid-connected photovoltaic power; in February 27th this year issued opinions: from March 1st onwards, produced for power generation facilities ordinary user's clean energy, will be stipulated by the State shall be the full purchase price. These clean energy, including solar, wind, biomass, geothermal and other.
After reporter from the Ningbo Electric Power Bureau, personal construction of photovoltaic power generation system, the State Grid purchase price is about 1 yuan / degree, if the photovoltaic power system state subsidies, the purchase price is about 0.5 yuan / degree. Power Grid Corp to provide free access to services, and provide two-way measuring meter.
Photovoltaic grid-connected steps the reporter understands as follows:
1 residents to the power supply departments to apply for access to the national grid;
2 Power Grid Corp staff after the scene investigation, put forward to the user access scheme. The user according to the access plan, installation can be entrusted to a qualified third party company. Photovoltaic power generation component can purchase their own or using DIY, equipment needs to be in line with national standards, and ultimately by the authoritative department approval.
3 according to the geographical position of Ningbo, monocrystalline silicon or polycrystalline silicon photovoltaic panels facing south, horizontal tilt angle of about 33 ° best.
4 power grid enterprise grid and acceptance of equipment user installation, and signed the relevant agreement, to the residents of photovoltaic power users, a commitment to complete the grid-connected power grid enterprises work in 35 working days.
Previously, Tianjin first residents of grid-connected photovoltaic generation, request the local power sector: residents residential owners Commission, the need to provide owners of the Committee and adjacent residential owners agree to install the certificate, and a commitment to the authenticity of the materials.
Rich solar resources in Ningbo
Build 5 kilowatts of solar power system
12 years can recover costs
At present, a set of 5 kilowatts of domestic photovoltaic power generation system in the price of about 90000 yuan. A 100 W photovoltaic plate area of 0.6 square meters approximately, 50 block is 30 square meters.
Ningbo a year of solar radiation data, there is no public data, but can refer to the same latitude in Hangzhou.
Hangzhou: latitude: 30 degrees, the optimum angle of photovoltaic panels: 33 degrees, the average peak sunshine hours: 3.43h, the average annual amount of radiation level: 1183 kwh / square meters, the annual amount of radiation surface: 1254 kwh / square meters.
According to the richness of illumination, solar resources can be divided into four levels. The annual total radiation more than 1750 kwh / square meters for the rich zone, 1400-1750 belongs to the very rich belt, 1050-1400 belt belongs to the rich, < 1050 belongs to general belt. Ningbo is rich with.
The amount of radiation Hangzhou slope is 1254 kwh / square meters, the photoelectric conversion efficiency of photovoltaic panels for the general 18.8%, and with the passage of time is reduced, the photovoltaic panels of life in general between 20 to 25 years.
The income, 5 kW photovoltaic power system, a year 7072 kwh electricity. According to the power grid 1 yuan 1 kwh recovery to recover the cost of 90000 yuan, residents of 12.7 years.
Ningbo introduced policies to encourage the development and utilization of solar energy
Start time, chasing the photovoltaic power generation in April 1st in folk fancier, Ningbo city hall has issued a "Ningbo city low carbon city pilot implementation". This plan encourages photovoltaic power generation. And the use of other clean energy also set development goals.
Wrote in the above scheme: "to encourage the development of distributed energy system" to "encourage the development and utilization of solar energy, the implementation of solar roofs plan, carry out distributed solar photovoltaic demonstration, by 2015, solar photovoltaic development scale reached 40000 kw."
At present, the photovoltaic Ningbo local detailed encourage programmes have not been announced, but the policy guidance, direction clear.
Subsidies for solar power generation, is the various countries general measures. Germany, the United States, Japan and other countries have earlier developed photovoltaic subsidies, and most of them are used in the station, public buildings, etc..
In 2009, the state ministries announced photovoltaic subsidies, the city building integrated photovoltaic application, rural and remote areas photovoltaic use given a fixed subsidy, subsidy standard limit of 20 yuan kwh. But the plan application of solar energy project photoelectric products installed capacity of not less than 50 kwh.
The first national residential photovoltaic power station 7 generating 200000 kilowatts
According to media reports, in 2007 43 kilowatts of Cixi day and home projects become the country's first residential photovoltaic power station, at present has been running for 7 years. The project investment is earlier, cost 3500000 yuan.
The project adopts imported equipment, the power generation for small basement lighting, the excess power.
The project annual power generation of about 30000 kwh, cost recovery needs 100 years. "But the utilization of renewable energy in the attempt, built in residential areas, let more people more intuitive understanding of the application of clean energy, an important demonstration significance far beyond the actual value." Cixi live built bureau relevant responsible person said.
Yesterday, the reporter in this area to understand, this set of photovoltaic power generation equipment has accumulated generating more than 20 kwh. |
