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."

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.

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.

Bullish the USA solar development - while the policy is not optimistic

Sharply reduce the price of PV systems in the past few years, but in 2012 and 2014 the cumulative effect of the decision of the Ministry of Commerce is to reverse the trend of cost reduction. If you look back to the spring of 2012, you will find the price of silicon component in the range of $ 0.80 to achieve the forecast price 85 / watt and modules at $ 0.55 to 6 yuan / watt range of analysts do not end in 2014, he said, We are nowhere near $ 0.55 to 6 yuan / W, in the United States in July 2014!

Currently, the cost of making the Ministry of Commerce, the US solar industry about $ 0.18 / W - and probably spend more at the beginning of next week. Now passed to the west coast of Mexico line Chinese module costs $ 0.58 / W. Delivered to the US West Coast same module cost American solar installation $ 0.76 / W. If not for a trade war, we can today buy silicon component in the US $ 0.58 / W or less!

A new report by the US Energy Information Administration forecast, by 2040 the new maximum generating capacity in the United States will come from natural gas and renewable energy. 830,000 kilowatts of new renewable energy capacity is forecast, nearly half are expected to come from PV systems.

Today, solar energy is the fastest-growing US renewable energy sources, because the report confirms that this will continue to be years and years to come. Rapid deployment of a national solar energy will create thousands of new American jobs and pump billions of dollars into the US economy, and help to significantly reduce pollution.

Equally important, it will also provide the United States are free to decide how their homes, businesses, schools and government facilities to provide power in the future. The report predicts 60 percent in the next few years all new rooftop solar PV installation will be created to save significantly when it comes to future energy costs.

If there is no trade war with China, the US solar industry will be in a great location by the 2016 end of year trade war with the ongoing cost-competitive with grid power supplied to the grid by 2016 cost-competitive in serious danger in. Lost 30% of the solar investment tax credit is set to achieve cost-competitive solar energy industry back years.

Congress of the International Trade Centre provides the solar industry has proven to be an excellent catalyst for many years to allow a significant industry growth and fantastic cost reduction. Now, with the line of sight of the target industry, and the other branches of government action it is frustrating efforts to reduce costs, and could seriously damage the development of the industry forward. It is time for the government to get collective action to solve this problem before it causes irreversible damage US solar industry. I hope that parents solar Obama can lead the effort to solve this problem.

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.

The new style of solar energy business

Creating a sustainable long-term DPV market will require aligning the interests of utilities, solar companies , technology providers, and customers. With support from the U.S. Department of Energy’s SunShot Initiative, a new Rocky Mountain Institute report—Bridges to New Solar Business Models.

Opportunities to Increase and Capture the Value of Distributed Solar Photovoltaics—looks at enhancing legacy solar business models or building new ones by creating an expanded value pool, one that makes DPV affordable and accessible to far more customers, bridges beyond individual customer-centric DPV value to include value delivered to the grid and society, and allows the electricity grid’s myriad stakeholders to share in that value.

To date, a series of misalignments and market failures—including pricing structures and lack of performance-based incentives—have prevented electricity system stakeholders from taking a holistic approach to the deployment of distributed PV. Solar companies and utilities have focused on low-cost deployment onto the grid without accounting for the operational benefits and costs of integration into the grid . As a result, significant value potential is being left on the table.

For example, solar companies have worked in isolation to reduce the pre-interconnection components of distributed PV cost, such as installation labor efficiency. Further cost reductions are possible, but the most significant of them will require involvement from both solar companies and utilities together to achieve, such as with streamlined site identification, PII, and customer acquisition.

Solar Company Role: Solar companies coordinate site selection with utilities and design and install projects on the distribution system where they can provide high net value. The solar companies would work in a competitive market for projects, either responding to utilities’ RFPs or installing projects based on utility pricing mechanisms.

Solar Company Role: Solar companies sell broader energy services to customers via technology packages the utility has screened and approved. Revenues could come from the company’s ability to package DPV with complementary technologies, increasing revenue per customer and expanding the potential market to include customers who see less risk if the technology package has utility approval.

Moving forward, to refine and implement innovative solar business model solutions across the U.S. will require direct engagement from regulators, utilities, and solar companies. This will include assessing current abilities to identify value and customer needs and developing multi-stakeholder processes for assessing value.
