According to GLOBALDATA data, those who strive to improve the carbon footprint through the installation of roof solar cell components to improve the annual price drop in the past decade. This data and analytics found that in 2013 – 2020, the price of the component system declined every year. After that, this trend suddenly stopped with the supply chain interruption associated with COVID-19. GlobalData’s power analyst attaurrahman ojindaram Saibasan said: \u0026 quot; From this perspective, in 2014, the cost of installing roof solar systems in an ordinary independent house is approximately $ 9,300. This number fell $ 600-900 per year, until 2020, the price dropped to $ 4550. In 2021, this price rose $ 700, which has never been seen since 2018. It is expected that these costs will not fall, which will last until 2023. \u0026 quot; GlobalData latest report \”2021 roof solar photovoltaic market – 2030 global market size, market share, main trend and major country analysis\”, 2013-2020, due to the growth of solar cells and components, roof solar price Descending trend. However, the logistics restrictions caused by COVID-19 epidemic have led to rising raw materials, and the price of solar photovoltaic system in 2021 has risen sharply. \u0026 quot; Delivery of delivery, plus lack of labor constitutes a major obstacle to value chains. It is expected that in 2022, the cost will grow moderately, then gradually decline in 2023 – 2030, which is due to the advancement of technology and the expansion of production scale. In order to overcome the epidemic challenge, some countries provide temporary relief in the form of rewards and tax refunds. \u0026 quot; 2020, a one-third of the global roof solar cumulative capacity installed in the household area, the rest in the industry. Saibasan added, \u0026 quot; due to the use of solar cell components, smart cities and micro-grids prefer small solar energy in the building materials, more and more households and industrial consumers are being to \u0026 # 39; product consumption \u0026 # 39; Transformation, that is, spontaneous use of people. This will make the growth of roof solar projects tend to stabilize. \u0026 quot; 2020, global roof solar photovoltaic power generation has a total capacity of 248.8GW, an increase of 23.8% compared to 2019. The market share of the Asia-Pacific region is 53.5%, and China only accounts for 12.4% of the global market. The proportion of Europe and South America is 29.1% and 13.6%, respectively, and the government in this area is developing through various long-term policies, financial incentives, subsidies, and tax benefits to promote roof solar photovoltaic project development.
