Summary of the IEA PVPS T1-43:2024 Report: Trends in Photovoltaic Applications

Core Content

The IEA Photovoltaic Power Systems Programme (IEA PVPS) is a global initiative aimed at advancing the role of photovoltaic (PV) solar energy in the transition to sustainable energy systems. This report, Trends in Photovoltaic Applications 2024, presents the 27th international survey of the PV industry, analyzing market developments, applications, and trends in PV power systems from 1992 to 2023. The report provides insights for policymakers, industry players, and energy providers to support strategic decision-making.

Main PV Market Development Trends

Global Installed Capacity

• Global PV capacity reached 456 GW in 2023, with China leading at 277 GW, followed by EU (59.8 GW), USA (33.9 GW), India (13.0 GW), and Brazil (12.4 GW).
• PV contributed 8.3% of global electricity demand in 2023 and saved 923 million tons of CO₂ emissions.

PV Market Segments

• PV systems are categorized into grid-connected, off-grid, distributed, and centralized (utility-scale) systems.
• Grid-connected systems are the most common and include both residential and commercial applications, often integrated into the built environment.
• Off-grid systems are used for basic electrification, especially in developing countries, and include applications like telecom base stations, water pumping, and vaccine refrigeration.

Dual Usage and Emerging Segments

• Agrivoltaics (combining agriculture with PV) and building-integrated PV (BIPV) are emerging applications.
• Floating PV is gaining traction as a solution for land scarcity, offering benefits like reduced evaporation and improved cooling.
• Vehicle-integrated PV (VIPV) and infrastructure-integrated PV (IIPV) are also being explored for their potential to reduce emissions and enhance functionality.

Policy and Market Drivers

PV Market Drivers and Support Schemes

• Government policies and financial incentives are critical in driving PV adoption.
• Feed-in tariffs, net metering, and renewable energy targets are common support mechanisms.
• The report emphasizes the importance of policy frameworks that encourage sustainable development and innovation in PV applications.

Prosumer and Energy Community Policies

• Prosumer policies support consumers who generate their own electricity and feed it back into the grid.
• Energy community policies promote collaborative models where communities or local stakeholders are involved in PV projects, enhancing social acceptance and local economic benefits.

Energy Transition Levers

• Policies that support the energy transition include renewable energy mandates, carbon pricing, and grid modernization efforts.
• Industrial and manufacturing policies aim to reduce overcapacity in the PV industry and stabilize component prices, which have been severely impacted by global market imbalances.

PV Industry Trends

Upstream PV Sector

• The upstream sector includes cell production, module manufacturing, and component supply.
• Crystalline silicon (c-Si) cells dominate the market, accounting for over 98% of total production.
• Thin-film technologies (e.g., CdTe, CIGS) are less common but are gaining interest due to their potential for lower manufacturing costs.

PV Manufacturing and Market Imbalance

• In 2023, China accounted for over 50% of the global PV market, with significant growth in installations.
• Global PV manufacturing faced overcapacity, leading to a collapse in component prices, especially for PV modules.
• The low prices in 2024 are unsustainable for the industry, but PV electricity is already cost-competitive due to its high efficiency and scalability.

Societal Implications

Climate Change Mitigation

• PV plays a crucial role in reducing greenhouse gas emissions, contributing around 2.5% of the energy sector's emissions reduction.
• The technology is seen as a cornerstone in the transition to decarbonized energy systems.

Economic Value

• The solar PV sector employs over 7 million people globally, highlighting its economic significance.
• PV contributes significantly to the economies of many countries, especially in regions with high solar irradiation.

Social Impacts

• Social acceptance and grid stability are key challenges in some regions.
• Community involvement in PV projects is important for long-term sustainability and local development.

End-of-Life Management

• The report highlights the need for PV end-of-life management and recycling strategies, as the industry grows and more systems reach the end of their operational life.

Competitiveness of PV Electricity

System Prices and Cost of Electricity

• PV system prices have decreased significantly, making it a cost-effective energy source.
• PV electricity production is now affordable and scalable, suitable for all system sizes and locations.

Integration and Sector Coupling

• PV integration into the energy sector is increasing, especially with sector coupling initiatives that combine PV with other energy systems (e.g., thermal, hydrogen, and electric vehicles).
• Hybrid systems combining PV with diesel or battery storage are being used in remote and off-grid areas, offering reliable and cost-effective power solutions.

Key Data and Findings

• Total business value in the PV sector in 2023 was $400 billion USD.
• 54 countries reached at least 1 GWp of PV capacity in 2023.
• 36 countries installed at least 1 GWp in 2023, with China leading the global market.
• PV penetration per capita is highest in Australia, the Netherlands, Germany, Belgium, and Spain.

Conclusion

The IEA PVPS Trends Report 2024 confirms that PV is a key energy source of this century, with high growth potential and increasing market share. Despite challenges such as market imbalances and low prices, PV remains a cost-effective, scalable, and sustainable solution for electricity generation. The report underscores the importance of policy support, technological innovation, and social acceptance in ensuring the continued growth and success of the PV industry.
