Photovoltaic: short for solar power system, a new type of power generation system that utilizes the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy, Steel Profile Manufacturer with independent operation and There are two ways to run on the grid.
At the same time, solar photovoltaic power generation system classification, one is centralized, such as large-scale northwest terrestrial photovoltaic power generation system; one is distributed (with >6MW as the boundary), such as industrial and commercial enterprise roof photovoltaic power generation system, residential roof photovoltaic power generation system.
1.From the perspective of national security, photovoltaic power generation can achieve the family’s own supply and avoid the destruction caused by war；
2.It can generate electricity on site without consuming fuel and erecting transmission lines;
3.It is not limited by the geographical distribution of resources, and has the advantage of being installed on the roof of the building at the same time;
4.Safe and reliable, no noise, no pollution, absolutely environmentally friendly (no pollution);
5.no risk of exhaustion;
6.high energy quality (currently the highest conversion rate in the laboratory has reached more than 47%);
7.users are emotionally acceptable and very fond of;
8.The construction period is short, and the time taken to obtain energy is short.
1.The application of solar energy is affected by climate and day and night.
2.Storage batteries using solar energy can also cause a lot of pollution.
3.Solar energy utilization equipment must have a considerable area.
4.Technical restrictions result in low energy efficiency, low efficiency, and high equipment investment.
The Development of Photovoltaic：
The EU proposes to impose anti-dumping duties on solar products produced in China from June 6, 2013, while Germany and 16 other EU countries have already expressed their opposition to the committee; some companies such as JA Solar (NASDAQ: JASO) have exceeded their first quarter results. market expectation. Can the photovoltaic industry be “nothing to come”?
The recovery is the most desirable word in the photovoltaic industry that seems to be unfavorable in recent years. Affected by the sudden rise of the US stock solar sector, domestic PV industry stocks have also begun to come out of a good market. At the same time, some PV companies listed companies have begun to invest again and let the market begin to imagine the recovery of the photovoltaic industry.
US stocks Solar Energy Solar’s quarterly report, which was much higher than market expectations, stimulated its share price to rise 70.37%. Subsequent to the stock market, the solar sector collectively skyrocketed. Immediately, the PV industry sector stocks in the A-share market also began to rise sharply. Sunshine Power Sanhua and Longji shares were trading daily. In fact, since the beginning of May, the trend of the stocks in the PV industry sector in the A-share market has gradually strengthened, and many funds have begun to gradually intervene in the sector that was once ruthlessly abandoned.
China Industry Insight Network analysts believe that the early effect of the capital market seems to be the best example of the hope that the photovoltaic industry will pick up. In the real economy, there seems to be evidence to support the recovery. The company announced that the company will spend 2 billion yuan to build 5 photovoltaic power generation projects, and said that the lowest expected internal rate of return is also close to 10%, the highest is more than 15%. Coincidentally, Zhonghuan also announced that it plans to invest with partners to build an annual production capacity of 25 million mm sapphire crystal rods.
