With the stimulation of the Chinese government’s “Roof Planâ€, “Golden Sun Project†and the forthcoming emerging energy industry planning, the cumulative installed capacity of photovoltaics is expected to reach at least 20GW by 2020, a compound annual growth rate of 46%. The inverter market demand is about 18.6 GW.
With the continuous increase in domestic PV investment, it is expected that more and more foreign brands and domestic companies will enter the field. Photovoltaic inverters are technically connected to conventional power supply and electric drive frequencies, which have the advantage of entering the field naturally. Photovoltaic inverter production does not require complex, bulky and expensive assembly production equipment, and the investment in fixed assets is small. At the same time, the supply of raw materials for upstream electronic components is sufficient and the cost is low. At present, there are fewer inverter suppliers with mature and stable performance. Therefore, the overall gross profit margin is maintained at more than 30%. The profits of the entire PV industry chain are gradually shifting towards the terminal. With the large-scale installation of power plants and the surge in the number of investors in the inverter industry, the gross profit margin is expected to decline, but it will remain at a relatively high level in the short to medium term.
Domestic enterprises have a certain gap with the most advanced level in foreign countries in terms of conversion efficiency, structural processes, workmanship, and stability. The level of low-power technologies is basically the same as that of foreign countries, and leading companies in high-power are close to foreign advanced levels. Increasing investment and R&D efforts have the potential to catch up with advanced foreign standards. Therefore, high-power inverters now have a good investment opportunity, and the low-power inverters of 3-5 kilowatts will follow the large-scale application of off-grid and grid-connected home-based units. Some improvements can be used as a secondary investment target. The domestic market for photovoltaic inverters is relatively small, but the huge business opportunities in the future photovoltaic power generation market and the series of cost advantages brought by the complete industrial chain as the world's largest photovoltaic producer have given domestic photovoltaic inverter companies and investment. The person has brought a historic opportunity.
According to relevant responsible persons of the CEC, more than 40 key photovoltaic grid-connected key technical standards participated by the China Electric Power Research Institute, the State Grid Institute of Electric Power, and relevant units have been led by the CEC and more than 10 standards have been formed for consultation. Of the remaining 30 items, drafts have also been formed. Industry insiders believe that the standard has a greater impact on power stations and PV inverters, or it will promote the upgrading of PV inverter industry. The improvement of photovoltaic inverter standards will standardize the development of the industry and will be beneficial to related companies.
To study the inverter-connected power devices in a megawatt-scale photovoltaic power plant, and to study the appropriate power topology and grid-connected control methods to achieve the maximum power tracking and inverter module grid connection of the photovoltaic power plant, reduce the impact on the grid, and improve the power quality. Meet the technical specifications of photovoltaic power plant megawatt-level inverter power grid power devices. The final product development of a megawatt bidirectional inverter was completed.
