The solar power industry had a record-breaking year in 2023. A total of 447 gigawatts (GW) of new solar capacity was installed globally, a devastating 87% increase from the previous year. This unprecedented surge was driven by several key factors including its manufacturing industry production capacity and the ongoing global energy crisis.
Global Solar Growth From SolarPowerEurope
Over the past few years, solar panel and component producers around the world have invested heavily in expanding their production facilities and upgrading their technologies. In China, the world’s solar manufacturing hub, production capacity for key components like polysilicon, wafers, cells, and modules all saw substantial increases, with overall module manufacturing capacity estimated to have surpassed 800 GW by the end of 2023.
This massive scale-up in production allowed solar manufacturers to achieve significant economies of scale, driving down unit costs and making solar products more affordable than ever before. The price of solar modules, for instance, plummeted by around 50% over the course of 2023 alone, reaching levels that were unimaginable just a few years ago.
The Dominance of China
Some of the solar power products are made by European companies, but most are produced in China, whose dominance of the global industry allows it to deliver solar power products at increasingly lower costs. The world’s largest solar market installed a staggering 253 GW of new capacity, accounting for an astonishing 57% of all solar additions worldwide. This remarkable performance cemented China’s position as the undisputed leader in the solar revolution.
Several factors have contributed to China’s solar supremacy. Firstly, the country has invested heavily in expanding its solar manufacturing capabilities, from polysilicon production to module assembly, with its production capacity now exceeding the terawatt level.
This concerted effort has paid off handsomely, as China’s solar manufacturing capacity has now exceeded the terawatt level. The country is the world’s largest producer of polysilicon, the key raw material for solar cells, with an estimated annual production capacity of over 1.4 million tons. It also leads in the manufacturing of solar wafers, cells, and modules, accounting for around 80% of global production.
This scale has enabled Chinese companies to drive down costs and make solar technology more accessible globally.
Secondly, China’s government has set ambitious renewable energy targets, aiming for non-fossil fuels to make up 20% of its primary energy consumption by 2025 and 50% by 2050. These policy initiatives have created a conducive environment for solar deployment, with the country now operating a cumulative solar fleet of 656 GW – more than the next four largest markets combined.
Regional Trends and Outlook
While China’s solar juggernaut has captured the global spotlight, other key markets have also made significant strides in 2023. The United States, the world’s second-largest solar market, bounced back from a turbulent 2022 to install 32.4 GW of new capacity, a 48% increase year-on-year. This resurgence was largely driven by the passage of the Inflation Reduction Act, which extended critical tax credits and incentivized domestic manufacturing investments.

Across the Atlantic, Europe solidified its position as a solar powerhouse, with the European Union adding a remarkable 61 GW in 2023 – a 50% year-on-year increase. Germany emerged as the continent’s solar star, more than doubling its annual installations to 15 GW, a new record for any European country. Spain and Italy also experienced impressive growth, underscoring the region’s commitment to renewable energy.
In Latin America, Brazil continued its solar ascent, installing 15.4 GW in 2023 and solidifying its position as the third-largest market globally. However, the country faced some regulatory challenges, including changes to its net-metering scheme that initially raised concerns about the impact on distributed solar deployment.
India, the world’s fourth-largest solar market, experienced a temporary setback in 2023, with its installations declining by 28% to 12.5 GW. This downturn was attributed to a lack of utility-scale project development due to factors such as delays, regulatory hurdles, and speculation on declining module prices. Nevertheless, the Indian government remains steadfast in its renewable energy ambitions, aiming to reach 280 GW of solar capacity by 2030.
Looking ahead, the solar industry’s growth trajectories vary across these regions. The EU is expected to continue its upward trajectory, with our Medium Scenario projecting a 5% increase in 2024 to 63.9 GW, followed by double-digit annual growth in the coming years. The United States is also poised for sustained expansion, with the IRA’s incentives expected to drive consistent growth. In contrast, India’s market is anticipated to rebound in 2024, while Brazil’s outlook remains cautiously optimistic, given the regulatory changes and economic uncertainties.
Technological Advancements and Cost Reductions
The solar industry’s remarkable progress has been underpinned by continuous technological advancements and manufacturing efficiencies, leading to significant cost reductions. Over the past year, the price of solar modules plummeted by around 50%, making solar power more affordable and accessible than ever before.
These cost declines have been driven by a variety of factors, including economies of scale in production, improvements in cell and module efficiency, and the optimization of manufacturing processes. As a result, the levelized cost of electricity (LCOE) from solar has become increasingly competitive with traditional energy sources, eroding the need for subsidies in many markets.
The affordability of solar has, in turn, unlocked a host of new applications and expanded the technology’s reach. Rooftop solar, for instance, has become a viable option for households and businesses seeking to generate their own clean energy and insulate themselves from rising electricity prices. Utility-scale solar projects have also become more financially attractive, paving the way for large-scale deployments in both developed and emerging markets.
Moreover, the cost declines have facilitated the integration of solar with other technologies, such as battery storage and electric vehicles, further enhancing the flexibility and versatility of the solar ecosystem. As these technological synergies continue to evolve, the solar industry is poised to play an increasingly central role in the global energy transition.
Policy Recommendations for Accelerating Solar Growth
To unleash the full potential of the solar industry, the Global Solar Council has outlined a set of key policy recommendations for policymakers around the world. Chief among these is the need for countries to set ambitious national targets for solar PV deployment, providing a clear roadmap for the sector’s growth and sending a strong signal to investors.
Equally crucial is the scaling up of investments in energy storage and grid infrastructure. As renewable energy sources like solar continue to disrupt the traditional power system, the need for flexible, responsive grids and large-scale storage solutions becomes paramount. Policymakers must prioritize these enabling technologies to ensure the seamless integration of solar into the energy mix.
The Global Solar Council also emphasizes the importance of diversifying solar supply chains, both geographically and technologically. Overreliance on a single source or technology poses systemic risks, as the industry learned during the COVID-19 pandemic and the recent global energy crisis. By fostering free, fair, and open supply chains, governments can enhance the resilience of the solar sector and support its rapid expansion.
Beyond these recommendations, the Global Solar Council also highlights the need for streamlined permitting processes, the adoption of sustainable environmental, social, and governance (ESG) practices, and the development of a skilled solar workforce to support the industry’s growth.
