The International Energy Agency's Photovoltaic Organization IEA-PVPS recently released the "2023 Global Photovoltaic Market Snapshot Report" and estimated that the global installedPhotovoltaic system<\/a>The installed capacity reached 240GW. The agency used an improved method to estimate this figure, which is between the 190GW estimated by the International Renewable Energy Agency (IRENA) and the 268GW estimated by BloombergNEF.<\/p>\n

The IEA-PVPS report is based on data from a range of sources, including data on both grid-connected and off-grid PV systems.<\/p>\n

Outlining the global energy transition requires a documented approach, especially when reporting installed PV system capacity in various countries, as changing assumptions alter the forecasts of the global PV market. Estimating installed PV system capacity is becoming an increasingly complex task for research agencies, but high-quality data is essential to understand the trends and long-term development of the PV market. Without reliable, accurate and relevant information, policymakers, decision makers and industry stakeholders may not be able to respond to market trends in line with their strategic goals, such as policy adjustments, planning of grid expansion and maintaining the stability of the power system.<\/p>\n

For several years, various research institutions have provided conflicting information on the size and growth of the PV market. Predictably, the distributed nature of PV systems complicates these estimates, especially for countries with weaker tracking and reporting capabilities for installed capacity of PV systems. But the consequence of conflicting data provided by international organizations and consulting agencies is that industry players have lost confidence in market figures and subsequently in the development of the global PV industry.<\/p>\n

For 2022, IEA-PVPS has published PV system installed capacity between 192GW (IRENA) and 268GW (BNEF), while the actual installed PV system installed capacity is somewhere in between: IEA-PVPS believes that 240GW is a fairly close actual installed value.Photovoltaic modules<\/a>The DC figures are used to calculate energy output, while the AC figures refer to the theoretical maximum power output of the PV system.<\/p>\n

This difference in AC and DC installed capacity is the main reason for misunderstandings in reporting PV system installed capacity and makes it difficult to clearly understand the actual situation in the PV market. For example, the PV module installed capacity reported by Chinese PV module suppliers in 2022 was calculated based on AC installed capacity, rather than DC installed capacity as understood by international experts, which led to significant changes in the final reported PV system installed capacity.<\/p>\n

China's National Energy Administration said that China installed 87GW of photovoltaic systems in 2022, while the "Global Photovoltaic Market Overview 2023" released by IEA-PVPS showed that based on the AC-DC ratio of China's utility-scale photovoltaic power stations, China installed 106GW of photovoltaic systems in 2022.<\/p>\n

Given the seemingly wide range of data published by authoritative organizations, it is difficult for industry professionals to determine which agency or organization to use. Generally speaking, when completely different estimates are published, one agency may publish DC installed capacity and another agency may publish AC installed capacity, but what other factors should be considered?<\/p>\n

Many factors can influence how to report annual or cumulative installed PV capacity. There is currently no international reporting framework for PV capacity, and each country has its own reporting practices that vary depending on the data collected and the purpose for which the data is collected. In many emerging markets, installed off-grid PV systems or PV systems at the edge of the grid are often not reported. Data on distributed PV systems cannot always be tracked correctly, and reporting practices in different countries add uncertainty to the numbers.<\/p>\n

Why did IEA-PVPS choose DC installed capacity for its estimates? This is because, compared with the AC power of PV systems, the DC power of PV panels is more closely related to power generation, market turnover, PV panel surface area and land utilization. Of course, when extrapolating from these values, other factors must be considered, such as the pollution of PV power generation or the average system cost of different parts of the market turnover.<\/p>\n

Even data from primary and reliable sources is subject to uncertainty, as industry experts and analysts in some cases convert AC capacity to DC capacity, while different reporting practices may mean that repowered and retired PV systems are counted differently, or not at all. In some countries, installed micro PV systems may not be reported, and the same is often true for off-grid PV systems. In countries where data collection methods are less reliable, approximate sources and expert guesses provide sufficient information, given the small overall numbers involved.<\/p>\n

The IEA-PVPS recently released the "Global Photovoltaic Market Snapshot Report 2023", which is based on data provided by experts from various countries and data collected and analyzed by the report authors, statistics on the global grid-connected and off-grid photovoltaic system installed capacity, as well as estimates of unreported photovoltaic system installed capacity, and converts the installed photovoltaic system capacity data into DC installed capacity data. The report aims to provide coherent, accurate and useful data for comparison between different countries and between different years.<\/p>\n

Growing global photovoltaic market<\/p>\n

The 240GW reported by the IEA-PVPS this year is an estimate based on the best available data and covers a large part of the global PV market, however there are uncertainties that should be taken into account. Compared with the 175GW of PV systems installed worldwide in 2021, the growth of the global PV market is considered to be consistent with the increased interest of developers in installing PV systems. By the end of 2022, at least 44GW of PV modules have been shipped, and the annual production of PV cells and wafers is in the range of 300GW, indicating that the manufacturing industry is confident in the growth of the global PV market.<\/p>\n

Due to the impact of the COVID-19 pandemic on the production and installation of PV modules, the delays in 2020 and 2021 were partially compensated in 2022, but will also have an impact in 2023, with the number of PV systems expected to be installed much faster than the actual number of installations.<\/p>\n

To ensure informed decisions, it is important to choose the right data source and understand its limitations and advantages. As an early review of the global photovoltaic market last year, the IEA-PVPS report provides a quick overview of market and policy trends. The global photovoltaic market is growing rapidly, and inadequate reporting of data has clouded people's perception of this growth.<\/p>\n

Some countries are adopting more efficient methods to track and report installed PV systems, especially in emerging countries. Collaboration between research institutions will also help to better report and avoid conflicting statistics in an increasingly complex energy ecosystem.<\/p>","protected":false},"excerpt":{"rendered":"
