Position: GeMinG > Analyze the market prospect of photovoltaic dual-axis power generation system from the status
Chian Linear Actuator Website: Photovoltaic power generation as a kind of green energy has attracted worldwide attention in recent years. Take the United States, a world power, as an example. In the United States, photovoltaic power generation has taken place during the blowout period in recent years. In the United States alone, new installed capacity of photovoltaics reached 14.625 GW in 2016, an increase of 95% compared to 2015. This year's US scaled photovoltaic installation For the first time since 2011, it has surpassed residents' rooftop photovoltaic installation capacity, fully reflecting its market potential.

Li Hong, President of Palma Energy, a well-known new energy company in China, told the reporter that the photovoltaic tracking power generation system is the current development trend of the international photovoltaic industry. The earlier photovoltaic market was dominated by fixed photovoltaic power generation, and later fixed adjustable brackets and flat single-axis brackets , single-axis tracking support, dual-axis tracking support and other components, currently tracking photovoltaic power generation systems account for only about 5% of the market share, while the foreign market has accounted for more than 50%, especially the most developed US market has reached 60 %.

From the perspective of short-term investment cost, many investors will choose several fixed or single-axis tracking systems in front, but from the perspective of long-term power generation revenue, the dual-axis tracking system will be more appropriate, of course, the prerequisite is a stable and efficient, The reliable and low-maintenance dual-axis tracking technology cannot be widely promoted in the market without such tracking technology as an aid.

According to a report released by the latest international research company IHS, currently the world's large-scale ground-mounted photovoltaic power stations will continue to adopt photovoltaic component trackers. These systems will become the technology of choice in North America in the next five years, including single-axis photovoltaics. The tracking system is the main reason. This is because its photovoltaic dual-axis tracking system has not yet solved the key issues such as its reliability and installation cost, but the US market has already been making active attempts in this regard because, for the moment, photovoltaics The power generated by the two-axis system is obviously higher than that of a single-axis system. From the current market feedback data, the single-axis tracking power generation is 10% to 25% higher than the fixed one, and the dual-axis power can be as high as 45%. The gap is undoubtedly very great.

According to Li Hong, president of Palladium Energy, “This will be a development trend. Since the advent of photovoltaic power generation, the cost of the fixed-to-track components has been continuously reduced, and the power generation capacity has also been continuously improved. China’s early PV tracking system has emerged. The phenomenon of overheating is abnormal, there are many problems in the tracking system on the market, lack of reliability, many application failures in many regions led many investors to dare to try again, in recent years, tracking technology, especially in the field of dual-axis tracking system technology more mature 5% of the market share has been unable to meet the development needs of the domestic photovoltaic industry. The timing of the popularization of the photovoltaic tracking system, especially the dual-axis tracking system, has already come.”


At present, many domestic companies have made daring attempts to develop and innovate photovoltaic dual-axis tracking systems. Li Hong told reporters that in order to effectively improve the reliability of photovoltaic dual-axis tracking systems, Palma Energy has replaced DC motors. Alternating motor, an attempt to replace the slewing drive with a DC electric push rod drive. After a long period of installation and debugging, it was found that the replacement of the photovoltaic dual-axis tracking system is more convenient to install, the performance is more stable, effectively solve the defects of the rotation system, motor and controller misalignment, bearing slipping, and the most important is the compression cost. A key step has been taken on the road to improving the reliability of photovoltaic dual-axis systems. It is believed that as the technology continues to mature, the promotion and application of photovoltaic dual-axis tracking systems will achieve tremendous breakthroughs.
