Online shopping "solar power station" Liaoning turnover ranked twelfth
The expected cost within one or two years will be reduced to 2 yuan / watts
Morning paper dispatch (reporter Zhang Han) recently, Liaoning's weather has been cold, so many people put their eyes on the electric heating, air-conditioning and other electrical equipment.
However, stepped tariff imposed last year, also let many people use electricity to with great care, and Taobao, attention to solar power generation equipment will be "bullish".
Online shopping "solar power station" Liaoning turnover ranked twelfth
Yesterday, the reporter in Taobao input "solar", jump out of the commodity results up to 25500 pieces, but Taobao data show, "solar" Taobao has become the hot search words, search index than the last thirty days "solar" a word rose 48.9%, compared with the same period last year rose 47.7%. And the "solar" products, clinch a deal the index link thirty days recently rose 47%, compared with the same period last year rose 115.2%.
In a substantial increase in turnover, many belonging to the Liaoning consumers, from Taobao data, Liaoning area turnover index ranked twelfth in the country.
Taobao, a Guangzhou seller said, the majority of buyers are buying some small power products, mainly solar power + light bulbs or charger system products, used to solve the home room lighting and mobile phone charging, this kind of commodity prices.
A power board and a battery, can basically meet the ordinary home lighting
The reporter in Taobao input "solar", jump out of the commodity including solar panels, solar power systems, solar battery, solar controller etc.. A Shandong solar power supply system vendors introduce Mr. Liu, can use the device from the family power station is the need for complete purchase.
"Power system consists of photovoltaic components, screws, controller, battery, inverter and other equipments." Mr Lau said, "power system with different components can be composed of different power."
Mr. Liu, a photovoltaic panels can generate 200W of electricity, equipped with a battery, which can satisfy the basic needs of ordinary household lighting, and if the drive other high power household appliances, will need to increase the number of PV panels and batteries.
Mr. Liu said, power system configuration, mainly to see consumers need more power, the seller will provide "discount-style" supply according to the demand of consumer. "We will put all kinds of equipment of the system need to buyers, buyers according to instructions for simple installation, can be used directly."
Family: daytime energy storage power station to generate power at night
Shenyang Institute of Engineering, director of new energy research center Professor Ju Zhenhe introduced, this concept of solar power generation system is very fresh, but in fact this equipment has been in existence for a long time.
Ju Zhenhe, a household solar power station, by solar panels, battery, controller and inverter components. The working principle of the solar power system is, the day in the sunlight, solar battery components have a certain power, and to charge the battery through the charging and discharging controller, the energy is converted to electrical energy storage. And then through the inverter, the direct current into alternating current for AC electrical appliances.
And the core of these devices is part of solar panels, the top part of the value of it is the solar power system.
The battery and the battery board matching, and its role in the light emitted by solar panels store energy, to be released when needed. While the main role of solar controller is to control the working state of the whole system.
1000 watt power station cost 10000 yuan
Reporters yesterday in Taobao Search, enter the domestic photovoltaic power generation system, found a total of more than 20. Among them, a set of 5000 kilowatts of photovoltaic solar power system known as for family electric, offer 100000 yuan, while a 3000 Watt, the quoted price is 67500 yuan, transactions are not recorded.
Mr. Liu said, he is in Shandong manufacturers direct sales, the cost is relatively low, a set of 3000 watts of equipment price also is in 30000 yuan of above. It mainly consists of 16 panels, 16 battery and a set of control system, the inverter and the battery board bracket device.
Professor Ju Zhenhe, the family built solar photovoltaic power station, the investment cost is relatively high, the current capacity of 1 watts of the cost of 10 yuan. The household family electricity capacity calculation of 1000 watts, to build a photovoltaic power station, to invest at least 10000 yuan.
Reporters from the city of Shenyang power supply company was informed that, at present has not received the enterprises or individuals for distributed power grid service, the staff also said, want to apply for the distributed power grid, can go to the customer service center or dial 95598 for consultation.
The initial cost is much longer and save money effect more obvious
Professor Ju Zhenhe, influenced by the weather and sunshine, the use of domestic solar power station will also be affected, "photovoltaic panels to a power of 200 Watts as an example, it is 5 hours of continuous work to produce electricity for 1 degrees, the meteorological data of Shenyang in 20 years, Shenyang average annual sunshine time is 5 hours, that is to say PV panels of a power of 200 watts, at least a day can generate electricity 1 degrees.
In this way, a family as long as the installation of photovoltaic panels around the block 5, a day can generate electricity 5 degrees, basic may realize the family supply provide for oneself, and it only needs 10000 yuan investment. But if the family population, consumption of large, 1000 watts is not enough."
Professor Ju Zhenhe, from the meteorological data of Shenyang in 20 years, the longest even cloudy days is 3 days, the battery we design also takes into account the Shenyang even the cloudy days, can be filled with electricity of the battery in the light of sufficient time, to maintain the electric quantity storage time to 3 days or more, so even if the encounter. It can also realize the power supply.
Although solar power system installation cost more money, but with longer, more electricity, saving effect is more obvious. But at present the development of photovoltaic industry is very fast, the cost of the decline is obvious. "A few years ago, 1 W photovoltaic power generation system cost is 100 yuan, has now dropped to 10 yuan, is expected to one or two years, the cost will be reduced to 2 yuan / watts, such word, solar power is applied to the cost of basic civil disorder will eliminate the."
