Solar pv inverters in China's booming market

The most significant way to reduce greenhouse gas emissions is the use of renewable energy, green energy generation including the use of renewable energy sources such as solar, wind, air and hydro power generation, thus reducing carbon dioxide and other harmful emissions greatly.

PV inverter integrated energy storage device availability has increased significantly, which helps resolve among renewable energy industries for effective load management growing demand, because the energy storage device to ensure the continuous supply of power, and to minimize interruption, load management to become more efficient, thereby increasing the reliability of the grid.

Chinese suppliers are doing the main beneficiaries, with full occupation of the domestic enterprises for the second consecutive year the position of the top 10. According to IHS report, the growth of China's PV inverter market more than 100% last year, domestic enterprises occupy the top of the charts. Market research, said the explosive growth of the inverter sales in China last year saw revenues mushrooms 亿 2012 from US $ 4 to US $ 8 billion.

"Caused by low local companies highly competitive pricing, highly complex business environment and lengthy credit terms obtained either from the success of a large share of the market to stop them, or forcing them to focus on other areas," IHS said. However, IHS said that growing demand will generate strong growth in the coming years, China PV inverter market, shipments are expected in 2018 will reach 18GW.

China has established the goal of distributed photovoltaic 8GW, 2014 IHS said that although a slow start means that only about 4GW will get built, distributed system, the inverter will become an increasingly important producer of market, prompting steering low power inverter.

"After the huge mounted utility-scale projects ground several years rapid growth in remote areas of the country, China has begun to pay more attention to the development of high power demand and distributed rooftop solar field," said Frank Hsieh, senior market analyst PV IHS.

"Although the share of small string inverters will occupy a growing market, IHS predicts that large centralized inverters remain the mainstream of utility-scale PV systems in China, due to its lower upfront costs and less connection point, "Xie end. "High-power inverters are expected to account for 80% of shipments to these systems by 2018."

How to make cheap solar power generation system

Get home solar power can be your needs, if you want to save money on your electricity consumption and want to do a little something is better than Earth. Since this is a thoroughly clean energy, you can use it as many times as you want devoid of destruction of nature, it is best found in the use of home cheap solar power.

Create your own home solar power system, and even has its own production costs gained more additional benefits. Retail solar energy devices can operate as countless hundreds of dollars. Their own home solar power technology, designed for a very small pair of hundred dollars.

It is believed that the new solar panels will cost thousands of dollars to get started a hundred bucks rely on size of your property and use the power of the reason this style. Although I've reported, I want to emphasize that the cost will be greatly reduced, if we do through our own system.

There are some data that you can buy cheap buy to build your personal panel. Excellent news is indispensable component parts can be ordered from local retailers, but this method is very fast. You can do two days of production. In addition, the cost of manufacturing in just a few hundred dollars varieties. That is why we call affordable solar electricity.

Solar power is not a block remedy the latest alternative energy sources, but even now in the cost of energy and the success of the phrase is the most feasible way.

Customers build their own panels to provide you with affordable energy can be your goal, you do not have to invest a lot can still be able to enjoy savings on your energy bills.

If you want to build your own DIY solar power system that you may or may not have been told the advantages of huge development with your own home solar power system that occurs varies. If you're sitting on the fence trying to choose, if you manufacture your own solar energy, there is a glimpse at some of these benefits will greatly exceed might help you get your ideas.

The most important advantage of household solar power generation system comprising: a retention money: Solar energy is free, in the sense that, once you have your system installed no further price, as long as you want, when you want a lot of use.

Green: This variety is very helpful power green, which means it does not set a damaging impression on the way. Solar energy is energy derived from sunlight collected, and for these types is a renewable and non-destructive energy it provides a variety of shocks over the outcome of any damage to the environment.

Go off-grid: use of solar energy in your home, you can minimize or totally avoid the use of energy drawn from the grid, which means you will not be in government policy, taxation, customs duties' or rationing. Going "off the grid" Another benefit is that you do not have more time to power problems.

The reward of solar power inverter

Solar photovoltaic systems, namely solar panels and the inverter output is proportional to the solar energy to generate power from the sun. This energy is instantly converted into electrical energy, can be used in the home or business. If the solar system produces more than appliances need that surplus is exported to the utility grid. If you are lucky, for some economic return, but for most solar customers next to nothing! This means that, unless you are using solar energy, because it is your production "given away" to the grid.

By increasing the local excess energy of this excess capacity to store it is needed, the inverter can manage the flow of power to ensure that you maximize your free solar energy, instead of wasting a "gift" to the grid.

Typically, this will be the first to use solar power, storage remaining, the use of stored energy during the night, if there are cheaper off-peak tariff - partially charged batteries at off-peak times. Some systems have a wisdom connected to the drive if the weather forecast the night before and decided to battery power from the cheap night rate charged or the following day from the sun to charge.

If we can prove, with real economic significance by using the energy generated by solar panels a day, so that the solar system will be enhanced. 99% of the domestic inverter fans and subway lights, may be television, but not for AC or refrigerator. So, if we started using fans, lighting almost entirely on solar energy, if it makes economic sense, equivalent to 2 - 3 years the return on investment should be good, we can spread the use of solar power in the country.

If the electricity consumption of the site and reduced access all the electricity from the panel, it will give you about 8--10 years to recover the investment. This high return is due to produce excess electricity to the grid can not be output to the higher export tariffs in Germany / UK / Spain / USA, general residential tariff low payback period of 3--5 years.

Although this is a good investment considering the very low O & M compared to replace the inverter battery trouble every now and then. In addition, power outages occurred mainly during the day time, therefore, the solar photovoltaic power generation can provide continuous supply has not run out of battery. So, effectively, you might last all day + 4 hours during the day, at night the battery supply + PV supply.

I think it is fair to say that the average income of families who can afford to have a spare battery inverter, can afford solar photovoltaic, if it provides some significant benefit more than business as usual. Challenge service providers face is to this benefit. This may be by economic interests or lifestyle or zero maintenance, fuel costs and other aspects no what these households click will be an interesting observation.

Real installations for roof solar

The rooftop solar PV need to take off, now and not later. Private households who can afford have, can occupy rooftop solar power in their homes who consume a greater extent on. Government subsidies is only one way and method by which you can provide with initial costs and payback periods.

At the same time, whether it is safe to place in every home is the need to study the issue. Solar photovoltaic array, its efficiency should be set up on the roof to provide enough power only when it is placed in the solar radiation can be used for at least 4-5 hours.

In siting customer-friendly way should be given priority. Otherwise, if any one of the requirements of solar photovoltaic roof and were allowed to return on investment may be a worrying factor. If if allowed to regulate the flow of electricity in rural households, if not in the strict supervision of the national electricity board, the service seems to play some of our private bank loans to customers who will be large-scale solar park dedicated player.

Its better affordable personnel may be provided with solar energy in the initial stage. Secondly, when it comes to rural electrification, without damaging the ecological balance, and solar power plants set up there can be generated and supplied to the grid for distribution.

I think there is electricity from rooftop solar installations produce a number of practical issues related to the solar power generating device:

Our low-voltage distribution network is unstable and very often it off.

All the grid feed solar inverter works following cable available frequencies.

In the case of the back of the shutdown is to follow them? Maybe they also have to shut yourself.

If it does not properly followed and the roof goes into the power grid, the wishes of the little guy in the entire grid load.

Suppose, the line was closed for repairs, it was back to the grid, who will protect service personnel from the back of the voltage.

Like this, there are many technical problems to be solved: then only it can be achieved.

I think the best option is passed on from generation point or stored in batteries that use at night with the inverter. Management must have this power generation efficiency from solar panels to the final end. Who better to do it with wisdom, you will be able to provide all-weather supply canyon free. Therefore, we have developed a very high efficiency solar inverters for different applications.

More interested in micro solar pv inverters

In recent times, we have seen an increase in our customers interest micro pv inverter . Micro-inverter is similar because they are the AC power generated by the solar module can be used in the home, and fed into the public grid solar generated direct current of conventional inverters.

Many people believe that micro-inverter is new, cutting-edge technology, they are not, micro-inverter technology can be traced back to the 1980s. Micro-inverter manufacturers have agreed to go into business, and then they went out of business after several years of big companies or the buyout. Micro-inverter commitment, because a single inverter for each solar cell module, the system as a whole will have a better performance. 

However, the micro-inverter is connected to the back of the rather conventional inverter modules each solar module, also known as string inverters, is installed on the ground, usually in the home and garage is different from that of a micro-inverter the conventional inverter drive for about 30 single solar cell module conversion efficiency. Therefore, the use of micro-inverter, 30 micro-inverters will be installed at the solar array roof of a typical family.

Micro-inverter supporters believe conditions degrade the performance of the system, such as a solar cell module coloration differences, between pollution and electrical characteristics are reduced or minimized, since the solar cell module is only such conditions will be affected and all other The module will operate their best to increase the overall efficiency of energy production. 

There is no basis on micro-inverter, data compiled dozens of actual real-world systems, offer than the traditional string inverters calculate the increase in energy harvest. However, in rare cases, micro-inverter is in a string inverters a better choice, as in the roof space of the house there are a number of different directions and an inverter MPPT tracker will not work or when the system is materially shadows. Otherwise, it is the author's micro-inverter, so as to avoid comments.

In dozens of system we have installed and micro-inverter in the customer's requirements, have had inverter failure. This makes sense, why we do not want to use this technology for all customers. Think about it, micro-inverter is an electronic device, which are mounted on the back of a solar module temperature exceeds 150 degrees.

Now, when a micro-inverter fails, it is not an easy fix, technical staff to get on the roof, tearing down the entire array to the inverter array fails, install a new micro-inverter, and re-install the system. It sounds like a good idea? It is disturbing to see that some of our competitors have to offer micro-inverter standard. 

In about two years, they will spend most of their time doing service call failed system. This may lead to the demise of their business, then we will have to serve these isolated systems. I do not care, but definitely not good for the local industry as a whole. If you're a homeowner looking to the sun has not been micro-inverter.

The implementation and development trend of solar inverters

Our sun is a naturally occurring nuclear reactors, solar power currently accounts for only four tenths of one percent of the total energy consumption in the United States, although the rapid decline in solar technology and increase costs, but we have to take advantage of the sun Energy-rich capability is on the rise.

Photovoltaic solar panels produce DC power. And DC power, electron flow in one direction around the circuit. This example shows a battery-powered light bulbs. Electrons move from the negative electrode side of the cell, through the lamp, and return to the positive electrode side of the cell.

With AC power, the electrons are sliding, periodically reverses direction, much like a car engine cylinder. When the AC power generator to create a coil magnet is screwed next. Many different energy sources can "turn the handle" this generator, such as a gas or diesel fuel, hydroelectric, nuclear, coal, wind, or solar energy.

AC power is selected as the U.S. power grid, mainly because it is a cheaper long-distance transmission. However, the solar panels to create a DC power. How do we get DC power into AC power? We use an inverter .

Solar inverter with DC-powered solar arrays, and use it to create alternating current. The inverter system of the brain. With DC to AC power inverter, they also provide ground fault protection and system statistics, including voltage and current AC and DC circuits, energy production, and maximum power point tracking.

Micro inverter launch is the biggest technological change, one of the photovoltaic industry. Micro-inverter is optimized for each individual solar panels, rather than the entire solar system, central inversion do. This makes the maximum potential of each solar panel to perform. A solar panel will not drag down the performance of the entire solar array, rather than the weakest link in the optimized central inverter.

Sunlight the solar panels on the roof, the panels energy into direct current, the inverter flows. The inverter converts the DC power to AC, then you can use it to power your home.

To be the growth of solar power is expected to double in the next two years, solar energy is the real wave of the future, the sun belongs to everyone, we are committed to unlock its enormous energy, so that we can all enjoy it provides freedom.

Focus on the development of solar pv power plant

While most people who have embraced the use of sunlight to generate electricity idea, this particular approach is beginning to receive some reviews, today we look at the development of concentrating solar power plants and photovoltaic power plants, both concentrated solar power plant will have a greater share than that distributed solar systems.

When it comes to solar power generation from solar photovoltaic panels will also help in photovoltaic power plants, whether CSP or PV plant will prevail in the debate has been debated for several years, due to the lower prices of photovoltaic PV LCOE of CSP in years past It is about half the cost, and will continue to do so until 2030.

Solar energy is distributed better account of damage to the environment will provide the same energy is important to compare the same technology is very important. Bird death was caused by an electricity tower, distributed solar is considering PV. In fact, the photovoltaic power generation does not cause the death of birds, often, but still large-scale photovoltaic power plants and distributed relatively very interesting.

Of course, the advantage of economies of scale photovoltaic power plants. On a global scale, multi-megawatt photovoltaic power station is to achieve less than 1 euro per peak watt. Largest photovoltaic power plant from the top 50 list of 50 megawatts to 300 megawatts or more can be found here. For the price of private housing investment may be a factor 1.5 higher, but in the field of digital capability has also been doubled recently.

On the other hand, the photovoltaic power plant without storage CSP plants like no challenge to its power grid produced a large amount of power is fed to the storage surface in. In this scale it on the electricity market competitive energy prices are often lower than the production cost. Each household can consume on their own, and may the subsidy, in order to obtain adequate remuneration for their produce electricity, but the utility to do so.

If the distribution of photovoltaic power generation is not evenly distributed, network integration issues will arise earlier, which should deal with the case-by-case, distributed PV can easily reach the size of a large power plant, but the optimal solution is not focused on having as many PV better. Renewable energy needs a clever mix of, among other factors, including solar, wind, biomass, energy storage will be necessary to overcome intermittent renewable energy production seasonality legacy.

Advantages and disadvantages of solar energy

Solar energy is being considered as an energy alternative to fossil fuels such as oil is very widely accepted renewable energy. First, take generations generations accumulation or accumulation of fossil fuels, which is why they are called non-renewable. Rising oil prices may be because we are slowly consume resources logo. On the other hand, the source the sun, the solar energy will always be around, and sunlight will never be exhausted. Fossil fuel is the culprit, the world is experiencing a dilemma carbon emissions. In contrast, solar energy is clean, non-polluting.

These are just two of the advantages of solar energy over fossil fuels. There are many. But, like everything else, has its drawbacks solar, but they calculate point-advantage to win.

After the initial investment, you will no longer need to pay a monthly bill for your energy consumption, the sun is free. In addition, solar panels are very low maintenance, when you buy high-quality panel, you may end up more than 20 years. Compare you will save on your monthly electricity bill for what the next 20 years is that it is compared with the cost of purchasing and installing solar panels, to find out how much you can save in the long run. In fact, you can even earn. If the power your solar panels produce more than what you need, you can sell excess power company. There are also some provisions that allow this.

Sunlight into solar power will not release carbon dioxide, which is a bad environment. This is why solar energy is known as green and clean energy. When you use solar power, you do not contribute to carbon emissions, which is harmful to the environment.

When you have solar panels generate electricity for your home, you are not connected to the grid. In case due to some reason or the other major power grid failure, your home will not be affected. If you and your family love camping, you can enjoy the peace and quiet in your RV and installation of solar panels on top of the remote areas.

The main disadvantage of solar energy is required to install the solar system initial investment. A large system that can generate electricity for your home would cost from $ 15,000 to $ 30,000. After the initial investment costs, however, you do not have to worry about paying your monthly electricity bill.

For many families as possible to convert solar energy is the government's goal. This is to reduce dependence on the power grid across the country. Even as the initial investment cost is quite expensive average homeowner, the government also introduced several incentive compensation costs, such as tax incentives or tax credits, up to $ 2,000. Homeowners can also take EEM or saving a mortgage, one borrower can finance their home advantage of energy conservation efforts.

Something important about pv power system

Photovoltaic panels convert light energy from solar cells directly into DC power. The word "photovoltaic" comes from the word "photo", meaning light, "V", from Alessandro Volta, a pioneer in the study of electricity. Therefore, the "photovoltaic" literally means "light - electricity."

"Off-grid" or independent, solar photovoltaic system is not connected to the grid, and often rely on battery storage power generated by the solar system. "Grid" solar photovoltaic systems connected to the grid, allowing you to use electricity at night or when the sun do not shine. When your solar panels produce more electricity than you use, the electricity can flow back into the grid, if you have an active program of net metering program. This allows you to rotate the credit meter backwards.

Montana between the size of most residential kilowatt photovoltaic system 1 and 5. The more you save energy at home, you need a small renewable energy systems, as well as lower costs. Therefore, investing in renewable energy systems before, focusing on protection! Check out our resource conservation.

Costs range typical residential photovoltaic systems from $ 10,000 to $ 20,000, including installation. However, due to the incentives and tax breaks, you can up to 50%, in order to reduce the cost of the system.
