What are the problems faced by the development of Qianjiang rooftop photovoltaic power generation equipment in 2018

question 1: how can residential solar energy play its potential in China

in 2017, China's solar photovoltaic power generation was 54 GW, but a relatively small amount was applied to personal roofs. Commercial and industrial (c&i) roof photovoltaic development is very good, and few people in the residential solar energy industry remind of the large-scale amazing growth, but why do Chinese families seem unwilling to increase their own roof photovoltaic? The answer to this question is not so simple

although there is no separate official residential installation data released, various calculations can be made on the potential size of this market. Trinasolar estimates that the potential number is about 40 to 50 million houses suitable for rooftop photovoltaic power generation. Based on an average of 5 kW per household, the total potential market size is about 200 to 250 gigawatts, worth more than 1 trillion yuan

in 2015, China's residential roof market began to grow, and about 30000 units had been installed at that time. 150000 sets were added in 2016, and increased to 250000 sets in 2017. This year, industry insiders estimate that at least 400000 residential photovoltaic systems will be installed. One of the major players in China's home roof photovoltaic market, 30000 units were installed in 2017?? The system hopes to increase this number to 200000 home installations by 2018

in 2018, China will install about 400000 residential PV, with a cumulative capacity of 2 GW. Analysts estimate that China will become the second largest residential roof photovoltaic market in the world in 2018, and will surpass the United States to become the global * market by 2021

considering the continuous decline of fit, home roof projects are becoming more profitable than utility PV. Further policy support from the Chinese central government may further promote economic growth

What are the problems faced by the development of Qianjiang roof photovoltaic power generation equipment in 2018? There are three main business models of rooftop PV in China* One is the traditional distribution channel, accounting for about 50% of the whole market. Distributors promote products including components, inverters, cables and installation, after-sales service and maintenance. Many traditional battery and component manufacturers have also developed their own distribution channels. For example, Jingke and Trinasolar have cooperated with 1000 dealers by the end of 2017, and plan to add another 1000 partners in 2018. Considering China's vast rural areas, distributors can help reduce market penetration costs and help brands occupy the market quickly

the second mode is roof rental, which is represented by Chint, accounting for about 30% of the market share

the third mode is direct sales. System integrators identify opportunities to enter the market. They promote their photovoltaic projects and outsource components from different suppliers. They are usually small, but they know the needs of local customers

the main obstacles hindering the development of residential photovoltaic are multifaceted. They include the limitation of transformer capacity, so in remote villages, the transformer capacity is not enough to meet the demand of roof photovoltaic power generation. This problem will be solved gradually from the upgrading of national electricity, but it is a problem at present

the electricity price of individual users in China is quite low, and the public demand for photovoltaic is also restrained. Moreover, there is no formal industrial standard for household photovoltaic, and there are many potential problems. Quality problems are common in project design, component selection, installation, maintenance and after-sales service. Many homeowners recognize low prices, but this means low-quality project risks. The government * recently convened a group including key players in this field to produce a national industry standard, which is expected to be completed in the first half of 2018. Under this industry standard, which is mandatory for all market participants, the quality problem will be solved gradually

*, due to (2) twists and turns: maximum force, twists and turns strength, deflection, modulus of elasticity, China's residential photovoltaic market is fragmented, and there is a lack of appropriate financing tools. This greatly restricts the development of the industry. However, there are also some news in this field: Jingke is cooperating with industrial and Commercial Bank of China and China Construction Bank to develop customized financial services for residential photovoltaic development through credit card points system

question 2: why is the price of rooftop photovoltaic in the United States so expensive, and how to reduce the cost

in mathematics, 80% of the cost problem lies in only two policy areas, and the solutions in each area have been verified overseas* One problem is the local license, which is currently a month's estimated time for U.S. installers and customers, but only a simple application form is required, just like the overseas certificate. The second is the electrical code, which needs a lot of simplification, which can shorten the installation time by half while ensuring safety and quality. Those who disagree with these simplifications believe that American safety and quality standards are relatively superior. I only ask those people how much of this belief comes from some form of national pride? How much comes from real data

both solutions do not require changes in federal policy, which is good news. The bad news is that thousands of decision makers have set licensing requirements and hundreds of stakeholders have created electronic codes. I believe that permission and code can and must be coordinated, with sufficient resources, and actively solve the offensive strategy and solar industry. Because we should be tired of playing defense in the solar world. The national focus is because the country will benefit * much and be politically ready for this huge leadership opportunity

we need an advocacy organization to strengthen leadership. We need every solar installer in the United States to sign a petition stating the need for automated interconnection (without a license) and the abolition of irrelevant codes. Then, we need to work hard to solve this problem, expand the scale of the industry, create hundreds of thousands of solar energy jobs, reduce energy costs in the United States, and save the earth. On behalf of our employees and customers, we cannot let American residential solar continue to bear twice the cost burden of overseas markets

question 3: how do European governments show support for rooftop PV

throughout Europe, the installation rate of rooftop PV has increased and decreased in recent years, in response to the support provided by European governments. From fit to net metering and loans to tax breaks, government initiatives have proven valuable, but often unsustainable, rooftop solar energy. So how can this boom and bust cycle be broken

at present, rooftop solar does not necessarily need direct financial subsidies, but cancels the administrative and technical costs of market access. The government can eliminate these obstacles by ensuring a fast and easy connection process and encourage the application of rooftop PV. Smaller manufacturers have no capital or ability to compete with larger equipment at all. Imposing the same requirements on them will suppress small solar equipment in the market. Therefore, roof solar energy should be exempted from balance, benefit from priority scheduling, let them enter the market, and ensure that they have a chance to succeed in the battle

the government can support rooftop photovoltaic power generation by supporting the cancellation of trade measures for solar panels. The transaction tax makes solar energy more expensive than European companies, consumers and the public* A recent report found that due to the sharp decline in prices, the cancellation of trade measures will lead to an increase of% in solar energy absorption by consumers in most EU countries. The elimination of trade tariffs will have a huge positive impact on rooftop PV and make the transformation of consumer centered clean energy a reality

question 4: how can the UK * maximize public support and credibility for rooftop PV

everyone likes to see solar panels installed on the roofs of homes, businesses and factories. Then, not everyone, but most people must do so. Distributed solar energy is the current form of electricity production in the UK * and there is little impact of sunny days in this country. So why didn't the British government take such measures? Leonie Greene, head of external affairs at the Solar Industry Association (STA), asked

when Westminster expresses this respect for the "will of the people", it is strange that this does not apply to energy and solar energy, especially the British government's own public opinion tracker of the Department of business, energy and industrial strategy (beis)

given the endless political debate in Britain over energy costs and the behavior of energy suppliers, ignoring solar energy is a mistake. Roof solar energy and energy storage provide a long-term solution for the stable energy bill. The government should promote these bills for the purpose of industry diversification and competition. 2. Relax the technical points of the experimental machine

the solar energy on the roofs of offices, warehouses and industrial buildings is what almost everyone wants to see, including Conservative MPs. However, the UK lags behind the rest of Europe in this key market. Unfortunately, the UK's policy framework has been neglecting to support larger roofs, although the 2014 DECC solar strategy rightly focused on it. In 2016, it insisted on the green and low-carbon year. After the listing and restructuring, fit did not make meaningful adjustments for the roof of industry and Commerce from the beginning. Therefore, a broader tax and regulatory framework can be realized now

in terms of fair competition environment, we hope to see the self use of roof solar energy, which has the same business proportion as the on-site gas-fired cogeneration. These are actually two options available to companies seeking on-site power generation, and the carbon free option is more heavily taxed. Due to the unusual taxes levied by the UK on factory and machine investment, including solar energy, "commercial interest rate" will be criticized by many international readers. This clearly created an unequal international stage. This and the need for productivity investment is why the elimination of business rates in factories and machines is a key requirement of all major business lobbying in the UK

we also hope to see increased capital subsidies for solar energy and storage. Fossil fuel investments such as shale gas platforms are eligible for 100% of the * annual capital subsidy write down. It is very wrong that fossil fuels are receiving tax incentives that renewable energy does not have. No one still has to put forward these arguments today

we also hope to see a large-scale fair competition environment for solar energy, that is, competitiveness in the price difference contract (CFD) competition. This is not in line with the interests of consumers and hinders the competition between technologies, which seems to be inconsistent with the spirit of the state aid rules

we need to convey the message that solar energy is still a good investment in domestic housing, and storage is increasingly transforming our beneficial economy. In this regard, some available consumer data are inaccurate, which is a problem we are trying to solve

however, what we see is the good leadership of local councils and local governments. Many companies have formulated new planning policies to help maintain this industry. We also know that many enterprises are firmly committed to the climate agenda, and their interest in solar energy is still strong, based on the consumption of two sticks per month. But it is frustrating that the national government's policy does not recognize and reward companies that do the right thing
