The World Solar Report 2024, released on November 5, reveals growth in global solar capacity. From just 1.22 GW in 2000, the world now boasts 1,419 GW of solar capacity as of 2023. This growth reflects a compound annual growth rate (CAGR) of approximately 36%. Solar energy now constitutes three-quarters of all renewable capacity additions worldwide.
Emerging Solar Technologies
Recent advancements in solar technology are noteworthy. Quantum dot solar cells have achieved an impressive efficiency of 18.1%. This innovation enhances solar energy capture and supports atmospheric water harvesting. Researchers are also developing self-healing solar panels, which promise to extend the lifespan and reduce maintenance needs of solar technologies. Additionally, solar-powered phyto-mining utilises plants to extract valuable metals from soil, presenting a sustainable alternative to traditional mining. Innovations like solar paver blocks and Building Integrated Photovoltaics (BIPV) are integrating solar technology into infrastructure, allowing for light transmission while generating power.
Cost Reductions and Market Trends
The 2024 report marks a consistent decrease in auction prices for utility-scale solar photovoltaic (PV) projects. The average cost has dropped to $40/MWh globally. India leads in solar PV capacity granted through auctions, achieving a competitive price of $34/MWh. Investment in solar PV technology is anticipated to exceed $500 billion by 2024, surpassing investments in all other generation methods.
Global Market Dynamics
China dominates the global solar PV market, accounting for 43% of the total installed capacity, equating to 609 GW. The United States follows with 10%, while Japan, Germany, and India each hold 5-6%. Emerging markets like Brazil, Australia, Italy, and Spain contribute about 2% each. In 2023, solar PV manufacturing capacity for wafers, cells, and modules nearly doubled, with China leading in component manufacturing.
Impact on Employment and Other Industries
The solar PV sector has seen increase in employment, rising to 7.1 million jobs in 2023, up from 4.9 million in 2022. This growth marks the sector’s importance in job creation and economic development. Solar-powered irrigation systems are transforming agriculture, with the global solar pump market projected to grow at a CAGR of 5.8% from 2021 to 2027. This growth is driven by the declining costs of solar technology and the cost-effectiveness of solar pumps compared to diesel alternatives. Agrivoltaics systems are also being implemented in livestock management, providing shade for animals while generating electricity.
Financial Innovations and Accessibility
The introduction of pay-as-you-go business models has accelerated the adoption of solar systems. Users can now pay for their systems in small, manageable instalments. Technological advancements have made solar energy more affordable, while new applications further encourage its use. Promoting technology and finance transfer to least developed and small island developing countries is crucial to ensure equitable access to solar energy.
