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.

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 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.

The Kind And Function Of Solar Electric Power System

Usually, Solar electric power system according to whether merged into public power supply, it can be divided into two systems : off grid solar power system and on grid solar power system.

Off grid solar power system also called independent photovoltaic power generation system, it means don’t depend on the power grid to operate soly pv power system. Except for the solar panels, inverter, it must equip with charge controller and big capacity battery. The principle of solar power system is to storage the electricity in battery when panels generate. And it will output from the battery when needed.

According to the different function, solar electric power system also can be divided into pure DC- power system and DC-AC power system. Pure DC power system is only suitable for driving DC overload, such as DC light, water pump, fans and TV ect… generally speaking, usually solar street lamp, garden lamp and small DC lighting system as like 5W, 10w, 30w. These are pure dc-power system; while DC-AC power system have 220V AC output voltage, that is to say, these are suitable for different kinds home electric appliance, usually above 500W system can output 220V output electricity.

On-grid solar power system means the system connected to the public supply, coordinate power generation system to household with the electric supply. In our country, it already have been connected to the public supply system for free, except for their own electricity, the remaining electricity can also sold to the state. Besides , on grid also divided into energy storage system and without energy storage device power system. When the weather is good and have enough generating capacity, it is no matter whether there is energy storage or not. But if you encounter rainy days, when the electricity supply have been broken down, energy storage system can be used for a part of the electrical use, but without energy storage system can not be powered up.

In a word, it will be much convenient if there is a small energy storage system --- portable solar generator when outage. More information, you could try http://www.poweroak.solar/

The Advantage Of Solar PV Power Generation

Solar pv power generation means through absorbing the solar radiation to generate electricity, if only there is sunlight ,it can install the solar power system. The generate electricity process and principle of solar pv power generation are very simple, it doesn’t like the fuel generator to mechanical motion, or consume the fuel, even generate any hazardous substance or gas. Recently years, which is the new energy source using project strongly promoted all over the world. 

Why solar pv power generation become more and more popular in the world ? Specifically speaking, there are three main advantages as below :

First, energy source are free, and have a sustainability. Solar pv power generation via absorbing the sun radiation to generate electricity, the solar energy is the most precious free source which the universe present to our human being. According to the statistics, exposure to the earth solar energy is much bigger than our wasting energy about 6000 times, this source all around the earth, do not subjected to geographical and altitude factors limit.

Second, convenient to use. If there is sun light , it can install the solar power system to power supply. Flexible distributed, solar power system can be eight big or small, large to the solar power plant, small to our Poweroak portable solar generator, both can nearby power supply. That is to say, it is suitable for tourism, exploration, household lighting, pasturing area, field working, forestry home, island fishing boat, border posts and other areas without or lack of electricity power.

Third, no pollution, no pressure on the environment. All process of solar generating are physical, don’t burn the fuel, and will not generate any substance, no pollute the air, don’t make the noise, either. It is really a green environmental renewable energy source.

Besides, with the improvement technology of solar power system utilization, generating efficiency will be great progress, and these advantages will be more and more appeared. What’s more, The home solar power system will take a good market opportunity and have a great development.

Portable Solar Power Generator System Erection Joint Method

Written by Sarah Hwong, Jan 19,2016

At present , more and more portable solar power generator systems have gone into many households. But how to install and joint that become one of the most important thing people care about. 

Portable solar power generator system is a generation device which integrate storage battery, charge controller and inverter in a mainframe box. All kinds of devices circuit and input and output cable have been fixed well, debug work also have been prepare well, the users can use directly do not need to install and debug. Only requires users to connect the solar panels.

For the panel power of solar power system below 100W, solar panel power supply cable can be directly inserted into the power input port of the system main box.

For the solar panels power is 200W or 400W, these solar power systems will be based on the mainframe of DC output to choose the way in series or parallel to connect the wires.Here, 200W power system AC output is 1000W, DC output 12V, which are two pieces 100W panels with parallel connected; 400W power system AC output is 1000W, output DC 24V,which need four pieces 100W panels with 2 parallel and 2 series connected.

Schematic diagram:

The solar panel in series is connected a positive electrode of a battery plate with a negative electrode of the other battery plate; But the parallel is connected two panels in positive positive and negative negative . 

In a word, if you have any question about the erection joint method, or want to know more information about the portable solar generator, please feel free contact us.

Islands have off-grid solar generator system no worry about out of electronic

Off-grid solar generator system is run independently, can be used in a variety of remote areas. China's eastern and southern broad seas distribute a large number of islands, many islands are inhabited, but living electricity consumption is one of big problems. These islands are far away from the mainland, no matter from the economic or technology point of view ,it is not realistic to set up the grid power.

Before solar power generator technology, people can only use diesel generators to power . Every day can only be limited to use a few hours,  some household electrical appliances such as television, fan and refrigerator can not be used. Due to the oil of diesel generators need to be transported by boat from the mainland in the past, if the case of typhoon and other inclement weather conditions , generator can't use because of the lackness of oil. Even if generators use, it also have some limit ,the continuity of power supply can not be guaranteed.

Especially in some islands which are military uses, it is very obvious  the inconvenience caused by the power shortage. With extensive use of solar power system, which can be fundamentally change. According to reports, China a coastal defense regiment stationed in the island installed off grid solar generator systems, finally solve the problem of hard power.

In generally, islands are often very scattered, even though it can be erected grid, the cost will also higher than using solar power generator’s . In fact, not only in the islands, a lot of remote mountain areas and outdoor breeding places have these situation of hard power, these regions can take a consideration to use solar power system. Moreover , to consider the cost , families in poor areas can try portable solar generator to supply the power first.

The advantage of home solar photovoltaic power plant

In recent years, our country to support the introduction and implementation of different kinds of subsidy policy rules for photovoltaic power generation, home distributed solar photovoltaic power plant have been continuously increased in different areas , and into a blowout development.

The National Energy Bureau released the latest energy plan that will be in the Twelfth Five Year Plan of photovoltaic power generation installed capacity increased to 35gw, about 3500 billion of photovoltaic power generation market, which 2014 new photovoltaic power generation installed capacity to 14gw, distributed photovoltaic power plants accounted for 8GW, sustainable future national policy support will cultivate trillion level distributed photovoltaic power plant market.

Home solar PV power plant have five strong advantages as following :

1. Simple system installed and maintenance : high safety factor;

2. Can used our own power : The extra power can be sold to country’s;

3. Big policy-supported: Passed acceptance can be obtained by national and provincial level special subsidies for distributed solar photovoltaic power generation;

4. 5 years quality warranty : By the China Life Insurance Company of the quality of underwriting

5. High return : In case of Nanjing, residents spent 50,000 yuan invest one set of 5kw PV system, with an annual power generation of about 6080 degrees, per kilowatt obtained by national and provincial level subsidies total is 1.2 yuan, one year of generation comprehensive income about 7300 yuan, selling electricity revenues only need 6.8 years to recover cost, the annual rate of return of nearly 15 % , much higher than bank interest rates. Solar photovoltaic power products are available for 25 years, nearly 20 years to get a steady stream of fixed income after recover the cost.

Besides, with the popularity use of home solar photovoltaic power system, will be made an effort to reduce the fog and improve environment. 

If you think about the cost investment, I think we can start the portable solar generator first, to power some small appliances like light, fans etc... How about your ideas ? ??

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.

Solar power generator for homes into the remote areas

Household electricity in remote areas is still a big problem. This is not only in our country, but also in other countries and regions in the world.There is a story about the solar power generator for homes, more highlighted in absence of the basic power life is not so convenient. 

 Due to the double factors of economic and geographical conditions, electricity problem is difficult to solve. Basic lighting problems can only rely on kerosene lamps, it is impossible to use any other household appliances. But with people using solar power system, which provide a good way to solve this problem gradually.

   

As reports, in a remote area of Jianghua Yao Autonomous County in China, although in 2006 the village have electricity, but some groups are in the high mountain area, the erection of wire is very difficult and not electrified, about more than 100 households can not power on. Recently through the assistance of government organs and the science and Technology Department, more than 60 households have free access to the value of more than 20000 solar power generators, every household can install such solar power generator for homes equipment to power supply.

At present , the problem is that the cost of solar power generator has always been high, especially for families in poor areas, to use a solar power generator is very difficult . After all,the cost is too high,  government support is very limited, impossible a wide range of use. In fact, for these families who can choose a smaller portable solar generator to solve the lighting problem first, the cost of a simple solar lighting system can be much lower, which will be the most economical and practical.

Requirements for solar cells in photovoltaic power system

The solar cells are solar panels, also called solar photovoltaic . It is composed of a plurality of single solar cell according to the requirements of power and voltage in series or parallel combination together, and then through a special production process for packing. It is one of the most important components of solar photovoltaic system , must meet certain requirements.

First, solar cells from factory production to transport ,install and use, it will be experienced a series of shock and vibration external force, especially after installation should also be able to withstand the impact of hail. Therefore, it is necessary to have sufficient mechanical strength. Solar cells glasses must be tempered , and pass a fall experiment to test.

Secondly, after installing solar battery generator to more than 20 years of time , They constantly generate an electric current, experience all kinds of weather conditions, to prevent cell subjected to corrosion. Therefore, the component must has good sealing and insulating property, to windproof, waterproof, anti leakage.

In addition to the cell level of good or bad, the most important is product workmanship, the quality of workmanship has a direct impact on service life of solar battery component. So when purchase solar battery components, be sure to pay much attention to product workmanship . Before installation , you must pre-sort solar battery assembly, as far as possible combine the similar voltage or current of components in a square array to achieve the best effect. 

For planning to install solar photovoltaic users, they have to consider: Is your roof suitable for installing solar power generator system?? because it is directly related to the actual using effect. If not, you can consider the easy carry and best price of portable solar generator . Want to know more information, please visit http://www/poweroak.solar.com/

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.

Is solar electric power generator have fake goods?

Writen by Sarah Hwong,Dec.29,2015

“Is your solar electric power generator fake goods?” someone have asked me. I think it is not surprise for him ask that. 

All we are undeniable that counterfeit goods have been sold in the Chinese market for many years. It is difficult for customers to distinguish because many merchants mixed real and fake goods together to sell. A lot of people also have a lingering fear for it. But if you said there is also fake solar power generator, this is a little big exaggeration . I can clearly tell you : solar generator does not exist the so-called knockoff.

A buyer wanted to purchase one portable solar generator from our company. Who knew the product from our company website, also asked many questions like specification, function and price etc. I told  him patiently for all request. But he though the price was a little high. Yes, the price of solar generator is a little high because of high material and technology. In the end, he actually said our generator looks like a fake. I don’t know what to say any more. The high technology product is not easy to “copy” like mobile phone or other products. Our company have own brand “ PowerOAK”.

For the fake goods, I have something want to say:

First ,most fake goods copy the present popular brand product. Consumers will prefer brand products when buying. Some merchant couldn’t get their own brand, they often “copy” and  use someone else's brand to produce the same appearance goods and achieve confuse effect.   For the mobile phone, the brand concept play an important role in consumers’ mind. Somany famous brand have been copied. On the contrary, no    one could not copy the products which no famous or low sale. That is to say, solar generator is not the popular commodity, to copy is no meaning at all.

Secondly, at present, solar photovoltaic power generation system integration as a renewable energy source, which need high technology level. As long as the production of solar generator with high technology, you can have own brand to push to the market, there is no need to      copy other company .

In a word, it is redundant to worry about the solar electric power generator have fake. There is no fake, and no need to copy other company’s brand. With the development of social and technology, more and more solar power generator will be entered into homes. It is necessary to set up our own brand " PowerOAK"
