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."

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.

Strengthening promote the development of the inverter market

According to IHS statistics, the growth of China's PV inverter market more than 100% last year, domestic enterprises occupy the top of the charts. "China PV Inverter Market Report, 2014" market research firm, said the explosive growth of the inverter sales in China last year saw revenues mushrooms 亿 2012 from US $ 4 to US $ 8 billion.

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. In the top of the list for the fourth consecutive year the sun power, with a 30% market share, in 2013. Other top five vendors were TBEA Xinjiang New Energy, Emerson Network Power, Chint and Kstar.

But in fact all these enjoy less than 4% of the market share of each IHS said the description of the inverter facing Chinese manufacturers of production and management difficulties. Resulting in fierce competition in the low-priced local companies, business environment and highly complex or lengthy credit terms from success obtained a large share of the market to stop them, or forcing them to focus on other areas.

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.

Although the utility-scale PV projects accounted for 93% of the inverter revenue last year, IHS said distributed PV inverter market will become increasingly important producers.

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 ground-mounted utility-scale projects rapid growth years 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. This inverter for smaller growing demand will lead to modifications in 2014 and 2015 photovoltaic inverter supplier ranking.

Although small string inverters will occupy an increasing share of the market, IHS predicts that large centralized inverters remain the mainstream of utility-scale PV systems in China, due to its lower upfront costs and fewer connection points, high power inverters are expected to account for 80% of shipments to these systems in 2018.

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.

Solar inverter suppliers - how to master the sales tools and product prices

As the solar inverter has a very wide range of applications in the market, so it is the development of the whole industry is relatively large, more intense competition in the industry, suppliers formed a more intense market competition, the solar inverter suppliers usually sales activities, and ultimately gain a competitive advantage through the corresponding sales.

Market development and implementation of product strategy solar inverter supplier of the most important marketing tool in the sales process, which is related to key strategic marketing activities that require vendor attention. Competition in the market, often because a good reasonable price policy, you can make the product to occupy the market, to obtain a relatively short period of time leading market advantage, which is an important means of Avery after the sale.

In addition to pricing strategy, sales and marketing of solar power generation in the inverter manufacturers also need to strengthen product promotion activities. In general, solar inverter manufacturers often promote some products and suppliers can rely on manufacturers to promote propaganda, propaganda can effectively save costs, but also can effectively promote themselves, will help enhance the market competitiveness.

Sales process, consumers and customers tend to be the market price of the product concerned, a frequency converter products too. Meanwhile, the market price tends to affect the efficiency of product sales activities and fluency, the value of the solar inverter supplier of information products very much, but in order to ensure product sales, vendors usually selling prices for certain some adjustments.

Market demand and changing developments and market changes, and solar inverter suppliers need to be adjusted according to changes in product sales prices of the market. This is because the market demand is the ultimate goal, and household production, the need for any productive activities to meet the needs of the market, according to market demand to adjust the sales price can be effectively improved product sales, has more significance to the development of the industry.

Inverter Suppliers also adjust the products according to the specific circumstances of the market price of solar inverter products. This is because the production and processing of different technologies affect the inverter on the different products, these products and therefore have different performance, the price of the products is not the same as the natural level.

Emerging micro solar inverter technology

Discussion on solar energy systems tend to focus on itself, in the system the most obvious part of the solar cell module, and often overlooked another important part of the hardware is an solar inverter . The inverter is the solar panels into AC power of a component, which is home to what can actually use the DC power generated.

Some would say that the choice of the inverter is actually more important decisions than the solar module, since the solar cell module has played under the irradiation of sunlight gathered little "passive" role, while the inverter more actively manage it, while tracking data Record how much power is being produced.

There are two types of inverters: the classic central inverter and the emerging micro-inverter. Which one do you think is better. Central inverters have been used for more than 40 years. Micro-inverter is still a fairly new technology, only in commercial use for the past 10 years. Central inverters are usually installed on one side of the home near the main electrical panel, and micro-inverter is mounted on the back of the individual solar panel roof.

Central inverter required panel is divided into "string" or circuitry. If a panel strings with sun, causing it to lose production, all also affected in the string panel. However, with the micro-inverter system affects only pigmented shade single module; adjacent, unshaded panels still produce full functionality. Each micro-inverter is basically to manage their own independent solar cell module, rather than groups.

Similarly, the central inverter power of the entire solar system, and therefore, if the drive fails, the whole system to stop working until the inverter for repair or replacement. If the individual micro-inverter fails, the rest of the system is still working and productive forces.

About Inverter The most common question is about the warranty. Central inverter has a standard 10-year warranty, usually based on the size of the system, cost a little less; however, you can usually purchase an extended warranty. Micro-inverter is equipped with a standard 25-year warranty.

Not all brands of solar panels is compatible with micro inverter, due to its unique technology. It is very important to check with an experienced solar installation companies who can recommend the best system to meet your needs, both in terms of equipment and funds.

Stellar carry a variety of brands of central solar inverters and tingling micro-inverter, and since 1998 has been in the business, supporting the installation of commercial and residential solar energy systems, so we can at the right price with the right financing for home and recommend appropriate enterprise systems throughout San Diego.

Use some social media to promote solar energy

The solar energy fans who spent a lot of time on  facebook may have noticed how the use of solar topic page number mushroomed in the past year or so. Whether there may be more than facebook's loose and personal safety, and apparently can not be organized IPO, solar companies concerned and other renewable energy sector obviously feel it provides an excellent platform to promote the game changing renewable energy characteristics.

It can be said of other social media platforms. The ability to obtain fast and cheap to get the reader's news item or product innovation is likely to use the forum and the main advantage of social media. Perhaps another reader, the platform provides valuable interaction.

SolarQuotes no different, we would have ran informative Facebook Page running in the installation of solar systems, interactive questionnaire and a link to this page to keep fans informed solar events, such as new innovations or news and information on the latest tariff Government concessions.

Of particular interest to readers from SolarQuotes founder Finn Peacock regular series who, with his experience in the solar industry, keeping out of the wisdom of these issues by the bucket load optimal solar system to meet your house or how to choose suitable pv inverter or how to avoid the dreaded solar cowboy.

The correspondents are being considered, because he signed the importance of a new solar forum SolaMaps social media resources and solar energy on the weekend. The site claims that brings together people interested in solar energy, solar fan looks like a solar system, whether they use to find out more details or just interested in a good resource center. SolaMaps says its purpose is to bring together people who are interested in solar energy to share ideas, news, thoughts, etc., liken it to a coffee shop solar fan.

Which platform do you prefer? Facebook's? LinkedIn? Twitter's? Do you think Google plus social media, "the new kid on the block" to help spread the word solar comments are also welcome?

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.
