The International Energy Agency said recently that by 2027, solar power generation is expected to surpass coal-fired power generation and become the main mode of power generation. One important reason is that the installation cost of solar power has dropped significantly. According to the data, the average cost of construction and operation of solar energy of public utility scale has continued to decline since 2009. By 2021, it will only be about $36 per megawatt hour, a decrease of about 90% compared with 2009. The cost of coal has not changed much, about 108 US dollars per MWh in 2021.

Bahar, an analyst in the renewable energy market of the International Energy Agency, said that solar energy is expected to account for almost 60% of the new power facilities in the next five years. In addition, in recent years, governments around the world have paid more and more attention to energy security and have also issued corresponding policies to support it. According to the EU plan, the installed capacity of solar photovoltaic power generation in 2025 will more than double that in 2020, reaching 320 gigawatts, and 600 gigawatts by 2030.Editor/Ma Xue
