Electrical Energy Storage Systems Buying Guide

Someone will come up with, with the passage of time, the dependence is not sustainable, low output, low energy density of renewable energy to provide electricity for rural, will limit the development of rural areas and farmers?

This fear can't say makes no sense, however, this argument ignores the


some people might ask, depend on unsustainable, low output and low energy density of renewable energy will supply power to rural areas over time limit the development of rural areas and farmers.

This fear is not reasonable, but it ignores a key point.

Although renewable energy still has many defects, but they represent an outlet and a way out.

The introduction of renewable energy in rural and pastoral areas, they stimulate the farmers and herdsmen to accept modern technology, embracing modern life.

This is the basis and the further development of the rural power, not the ultimate goal of rural development.

To give more of the energy in rural areas and farmers to meet their needs for the independent development of rural areas is very important.

Renewable energy for farmers and rural population provides more independent choice.

They can start tomorrow to install photovoltaic panels, and in a few days or months access to electricity.

If the power can only supply when state grid laid out of the line, then when Tibet nyingchi or remote mountain village in guizhou Carey can access to electricity, depends on the local government long-term planning and budgeting for long distance transmission line, even depends on the national electric power planning as a whole.

The farmers and herdsmen in these regions is likely to be desperately waiting for a few years, even more than ten years, if not decades.

More importantly, the energy is not only the energy, also is the important foundation of social existence and development.

If rural energy can not rely on the government or the external factors, achieve energy independence, in the form of renewable energy in rural areas can control their energy supply, the population of the township's economic development and social cultural development can be more independent in terms of power, photovoltaic power generation development momentum, at least not constrained by the shortage of electricity.

From the point of view of environmental benefits, according to the current Chinese coal consumption of coal-fired power plants, photovoltaic power station can save 384 tons of standard coal, 4 each year.

8 tons 101 tons of dust, ash, 170 tonnes of carbon dioxide, and 7.
68 tons of sulfur dioxide.
It is truly pollution-free green energy.

From the point of view of social benefit, the plant integrated with building and photovoltaic power generation, do not need the use of expensive land, short construction period, low cost, do not need energy storage equipment, avoid and reduce the electric power transmission and distribution of ground loss, simple operation and maintenance.

A good overall design can make building cleaner and more beautiful, and easily accepted by the architect, users and the public.

Solar photovoltaic power station by the solar cell array convert solar energy into electrical energy power station.

Solar photovoltaic power station according to the operation mode can be divided into independent solar photovoltaic power station and grid photovoltaic power station.

Not connected to the public grid and independent power supply of solar photovoltaic power station called off-grid photovoltaic power station.

Mainly used in far away from the public grid of electricity area and some special places, such as remote villages, pastoral areas, farmers and fishermen, plateau and desert island lighting, watching TV, listening to the radio everyday use such as power stations.

The meaning of the development of photovoltaic power station is to provide electricity for special places, such as relay station, coastal and inland navigation marks, oil and gas pipeline cathodic protection, meteorological station, road grade and border posts.

Independent system consists of solar array, controller, battery, DC/ac inverter, etc.

Now the country's increasingly advocated the concept of energy conservation and environmental protection, solar energy here is very good use of it, so what is solar power?
What type is it?

Through water or other medium and device to convert solar radiation into electricity generating way,


now the country increasingly advocated the concept of energy saving and environmental protection, got very good use of solar energy, solar power is what?
What type is it?

Solar thermal power generation is a kind of work by water or other medium and device convert solar energy into electrical energy power generation method.

First of all, the solar energy is converted into heat energy, the heat energy into electrical energy.

There are two kinds of transformation patterns: one is the solar thermal energy directly into electricity, such as semiconductor or metal materials thermoelectric power generation, vacuum device and thermoelectric power generation, alkali metal thermoelectric conversion and MHD power generation.
Another way is through the engine (
Such as steam turbine)

Drive the generator using solar power, it similar to the traditional thermal, just heat energy comes not from the fuel, but from solar energy.

There are different types of solar thermal power generation, basically has the following five kinds: tower system, groove system, disk systems, solar pool and solar tower thermal power generation.

The first three is concentrated solar thermal power generation system, the latter two are focusing system.

Some developed countries will solar thermal power generation technology as a key national research and development, has built dozens of various types of solar thermal power generation demonstration plants, reached the practical application of grid power level.

At present, the world's most promising solar thermal power generation system can be roughly divided into the groove parabolic concentrator system, the central receiver or solar tower condenser and disc parabolic concentrator system.

Three is technically and economically viable form: 30 ~ 80 mw condensing parabolic trough type solar thermal power generation technology (
Parabolic trough)
；

30 ~ 200 mw point focusing centralized receiving solar thermal power generation technology (
Hereinafter referred to as the centralized receiving)
；
7.

5 ~ 25 kw point focusing parabolic dish solar thermal power generation technology (
Parabolic dishes)
。

Concentrated solar thermal power generation system of the main heat transfer working medium is water, steam, molten salt, etc.

The heat transfer working medium can be heated to 450 degrees Celsius in the receiver, and then used to generate electricity.

In addition, the power mode of regenerative energy can temporarily store for a couple of hours to meet peak demand.

Parabolic trough focusing system using parabolic cylindrical tank firing mirrors to collect sunlight on a tubular receiver, and heating tube of the heat transfer working medium to generate steam in the heat exchanger, so as to promote the traditional steam turbines.

Solar thermal power generation system using a set of independent tower heliostat tracking the sun, the sun gathered on the fixed tower building at the top of the receiver, to produce high temperature.

In addition to the above several traditional methods of solar thermal, solar chimney power generation and solar pool power generation such as new areas of research have made progress.
