–market Overview

Japan is the world’s major energy-consuming country and its energy is heavily dependent on imports. Japan, which has a shortage of resources, has been actively developing solar energy for many years. Solar technology is an important part of Japan’s national development policy. The Ministry of Economy, Trade and Industry of Japan uses various measures and projects to develop its own photovoltaic industry and capacity, including “New Sunshine Project”, “5 Years of Research and Development Plan for Photovoltaic Power Generation Technology” and “Residential Photovoltaic System Promotion Plan”. According to statistics, the market share of solar products in Japan has reached 30%, second only to Germany’s 39%.

As the world’s second-largest solar photovoltaic market, the Japanese government has been policy-assisted to promote the use of solar cells in the home. Since 1994, a grant of 900,000 yen/KW has been issued, which is close to half the system price. The system was suspended in 2005, but since 2009, the Japanese government has once again restored the solar power subsidy system for household use, which is a good opportunity for Chinese solar export companies to enter the Japanese market.

From the application side, in Japan, you can easily see single crystal photovoltaic panels appear in various occasions, building roofs, greenhouses, water surface photovoltaics… With government support, Japan’s distributed photovoltaics have been in the past two years. Great development, the intensive, aesthetic, and more power generation of monocrystalline panels are of great significance here, and they are developing rapidly. In fact, there are many places in Japan where single crystal products are used.

In addition, from the perspective of production supply, monocrystalline modules also occupy an absolute mainstream position in Japan. According to the statistics of the Japan Solar Power Generation Association (below), the total production of single crystal modules in Japan reached 771,532 kW in the first three quarters of 2016 (not counted in the fourth quarter), accounting for 57%, far exceeding the polycrystalline 43%. It can be seen that Japan attaches more importance to single crystal components than polycrystalline components.

It can be said that after the development of the previous year, the advantages of single crystal have been recognized by the industry and showed a strong returning trend. Combined with the technological development trend of the photovoltaic industry and national policy guidance, it is foreseeable that the single crystal will re-emerge in 2016.

Audience statistics of the exhibition in 2018

The audience visited 21,406 people on the first day, 20,866 people on the second day, and 22,127 people on the third day, totaling 64,399 people.

Why is portable solar generator green and energy efficient

solar generator power supply is a high-quality power supply with constant frequency, voltage regulation, purity and uninterrupted power. With the rapid development of modern information technology, the importance of solar generator power supply is becoming more and more obvious, especially in the industries where telecommunications, banking, finance and national defense have extremely high reliability requirements for the power grid! According to the system performance of solar generator power supply The standard defines three types of solar generator: standby solar generator; line interactive solar generator; double conversion solar generator. The standby solar generator power supply only supplies power to the load when the mains supply fails, and is always in the state of being output.

When the solar generator power supply can meet the requirements of various performance indicators of the mains, priority is given to the mains supply. Once the mains supply is abnormal, it is immediately converted to solar generator, so as to ensure the quality of the power supply. solar generator power supply costs are lower, performance is superior to the backup machine, and is welcomed by some customers who have certain requirements on power performance.

We can also look at portable solar generator power from the perspective of “environmental protection” and “energy saving”. In addition to avoiding or using harmful substances such as lead and mercury in the product, the “green” of the portable solar generator power industry needs energy consumption from the portable solar generator power supply, the overall IT system energy consumption and the energy consumption of the surrounding refrigeration system. Look at this issue in terms of energy saving. For a time, the concept of “green data center” was highly regarded by many portable solar generator power companies. Both manufacturers and users believe that green data centers can improve the operation of enterprises by reducing the cost of IT equipment, reducing environmental pollution, environmental protection, and improving IT operational efficiency.

To pay attention to the topic of “green energy saving” of portable solar generator power supply, we may first analyze it from three technical levels to understand where the portable solar generator power supply should be “sectioned”.

First, the energy-saving features of portable solar generator power supplies have been of concern to many portable solar generator power supply manufacturers. In the solar generator industry, the “input power factor” indicates the ability of the solar generator to absorb active power from the grid and its impact on the grid. This parameter not only reflects the ability of the portable solar generator to obtain active power from the grid, but also the degree of pollution of the solar generator to the grid. The greater the power factor, the stronger the ability to acquire active power and the less polluted the grid. It is worth mentioning here that the output power factor of the solar generator is also a key indicator, which reflects the adaptability of the portable solar generator power supply to non-linear loads.

Secondly, the modular design of the portable solar generator power supply and refrigeration system “on demand” can also avoid unnecessary energy consumption problems for users. Through flexible modular expansion, the portable solar generator power supply initially purchased by users can be gradually expanded from 20KVA to The 80KVA needed in the future will avoid the waste of equipment investment in the “big bulls and small carts” in the early stage of purchase, which can also save energy.

It seems that people’s use of green and portable solar generator power supply mode is already relatively mature, and has become an industry trend, there is no harm.

Solar power generation prospects and current situation analysis

The development of science and technology has led to the advancement of solar power generation, and solar power generation systems have also entered our lives. Looking at the foreign solar photovoltaic power generation industry, it has gradually matured, and the domestic market is also in hot condition. How far can solar power go? Sungzu made a simple analysis of the development prospects of solar power generation.

First, Solar power generation prospects – bright future

Looking at this issue from the perspective of a bystander, from a few years ago: solar power is likely to largely replace the current dominant coal-fired power station, and the current view: solar power has replaced coal. For one reason, the cause of global warming is the increase in carbon dioxide, and the characteristics of solar power generation are low-carbon and environmentally friendly, and the two are suitable combinations. Another reason is that the application of distributed solar power generation effectively improves the quality of life of people in remote areas and solves the problem that the national grid is difficult to transport electricity due to cost and technology. In remote areas, people use solar power to solve electricity problems.

Second, the prospect of solar power generation – home solar energy development has bottlenecks

There are two major points in the development of solar power:

1. The direct current generated by solar power can only be directly used for pure electric resistance appliances such as lighting and heating; if used in refrigerators, washing machines, color TVs, air conditioners, etc., household appliances need to be converted into alternating current through inverters, which can increase the investment and Operation and maintenance costs.

2. Household solar power is usually installed on the roof and the sun wall, requiring a unified design plan. Some places with poor lighting are constrained, combining the first two points, limiting the use of solar power in rural cities.

Third, the prospect of solar power generation – the problem that needs to be solved now

All technologies that can be widely used are constantly changing and innovating. Solar power generation must be widely accepted and used, and the following technical problems must be solved:

1. The first is whether it can greatly improve the conversion efficiency of solar panels. For example, the conversion efficiency of solar panels used on a large scale is increased from about 18% to about 30% under the condition of ensuring cost reduction.

2. Solve the safety problem of the power grid that the large power grid is subjected to the impact and vibration of photovoltaic power generation. Otherwise, the large grid cannot withstand the high proportion of solar photovoltaic power generation impact.

3. Significantly reduce the cost of solar power generation equipment, so that the cost per kilowatt is quite or even lower than the cost of conventional thermal power generation. At present, the cost of conventional thermal power is about 5,000 yuan per kilowatt, while the cost per kilowatt of solar photovoltaic power generation system is about 10,000 yuan. At the same time, the annual effective power generation time of conventional thermal power plants is more than 6,000 hours, and the effective power generation time of solar photovoltaic power generation systems is only 2,000 hours.

From the above analysis, it can be seen that in the long run, the future prospects of solar power generation are bright. If the photovoltaic technology problem fails to improve and adapt, it will become one of the constraints that restrict the development of solar power.
