The solar industry in Southeast Asia (SEA) is experiencing a significant transformation, driven by the region’s commitment to sustainable energy goals and the global push for a greener future.
Asia has been considered one of the leading regions in the global solar industry. According to data provided by Business Market Insights, the Asia-Pacific solar energy market is expected to reach a valuation of $334,342.91 million by 2030. It is estimated to grow at a compound annual growth rate (CAGR) of 14% annually.
- Southeast Asia’s energy demand is expected to triple by 2050, leading to a shift from fossil fuels to renewables like solar and wind energy.
- ASEAN countries have committed to ambitious renewable energy targets, with a focus on solar energy development and infrastructure improvement.
Southeast Asia’s total solar and wind energy generation have surged from 4.2 terawatt-hours (TWh) in 2015 to over 50 TWh in 2022. ASEAN leaders have set ambitious goals for the region’s energy future, committing to achieve 23% renewable energy share in the total energy mix and 35% renewable energy share in installed power capacity by 2025. The region has seen a substantial rise in solar farm capacity, exceeding 20GW across ASEAN countries.
But challenges such as supply chain disruptions, political dynamics, and anti-dumping tariffs must be addressed as nations strive towards sustainable energy solutions.
Key Factors Behind the Growth of the Solar Industry in Asia
The growth of the solar industry in Asia can be attributed to several key factors, each playing a significant role in driving the region’s rapid adoption of solar energy.
Policy Incentives and Government Support
Many Asian countries have implemented supportive policies and incentives to promote solar energy. For instance, China, India, and Japan have introduced subsidies, tax incentives, and favorable regulatory frameworks to encourage investment in solar power. These policies have made solar projects more financially viable and attractive to investors.
Technological Advancements
Continuous improvements in solar technology have significantly reduced the cost of solar panels and increased their efficiency. Innovations in photovoltaic (PV) technology, energy storage solutions, and grid integration have made solar energy more competitive with traditional energy sources. This technological progress has been crucial in making solar power a more accessible and reliable energy option.
Economies of Scale
The large-scale production of solar panels, particularly in China, has led to economies of scale, further driving down costs. China’s dominance in the manufacturing of solar panels has not only reduced prices but also ensured a steady supply of solar components, facilitating the rapid deployment of solar projects across Asia.
Environmental Concerns
The growing awareness of environmental issues and the need to reduce greenhouse gas emissions have prompted many Asian countries to invest in renewable energy sources. Solar power, being a clean and sustainable energy option, has gained significant traction as countries strive to meet their climate goals and reduce their reliance on fossil fuels.
Increasing Energy Demand
Asia’s rapidly growing population and expanding economies have led to a surge in energy demand. Solar energy offers a scalable and sustainable solution to this increasing demand, especially in regions with abundant sunlight.
The development of Asian Countries in the Solar Industry
The race to lead the solar industry in the Asian continent has begun, with various countries competing to take the lead. Countries like Indonesia, Thailand, Vietnam and the Philippines, among others, are striving to lead the solar industry in the region.
Vietnam
Vietnam has emerged as a leader in solar energy in Southeast Asia, driven by favorable government policies and significant private sector investment. With an installed solar capacity exceeding 18.4GW as of 2023, Vietnam is the largest solar market in the region, surpassing the combined capacities of all other ASEAN countries by a ratio of two to one.
The country’s solar expansion owes much to effective government measures such as attractive feed-in tariffs and robust net metering systems. Despite the expiration of a previous auction scheme, Vietnam has initiated pilot programs to foster bilateral power purchase agreements (PPAs), aiming to enhance market competition and sustain growth in the solar sector.
Under Vietnam’s eighth national power development plan (PDP VIII), the country aims to add 2.6 GW of rooftop solar capacity by 2030, as part of its commitment to reduce greenhouse gas emissions and bolster energy security. Looking ahead to 2050, Vietnam has set itself a total installed solar capacity of 170GW, representing 33% of total power generated. Projects like the 450MW Trung Nam Thuan Nam solar power plant and the 600MW Dau Tieng solar complex are pivotal in achieving this goal.
Thailand
With a robust domestic production center and a commitment to achieving net-zero emissions by 2050, Thailand’s Power Development Plan (PDP 2018-2037) aims to establish a total installed capacity of 15.6 GW of solar energy by 2035, benefiting from flexible national policies.
By 2036, solar energy will represent around half of the 29.4GW allocated to renewables in Thailand’s PDP. The country is among the leaders in solar capacity in Southeast Asia, second only to Vietnam.
Following US anti-dumping tariffs on Chinese solar panels, Thailand has become a manufacturing hub, especially in the Eastern Economic Corridor, although most production is exported. Recent tariff adjustments have led some manufacturers in Thailand and Vietnam to announce temporary production shutdowns.
Indonesia
Indonesia has been considered one of the pioneers in the development of the solar industry in Asia.
In 2021, the Ministry of Energy and Mineral Resources (MEMR) identified a solar potential of 3294GW. The government set ambitious targets: 3.61GW of rooftop solar energy by 2025, 26.65GW of floating solar energy, and a large-scale solar power plant of 4.68GW by 2030.
By December 2023, rooftop solar energy had reached only 140MW, far below the national target. Large-scale solar energy, according to Global Energy Monitor, stood at 21MW, placing Indonesia eighth among 11 ASEAN countries.
In January 2024, the MEMR revised regulations on solar energy integration, removing capacity limits on rooftop systems while implementing a quota system supervised by the ministry to feed electricity into PLN’s grid.
Philippines
The Philippines has been highlighted by Global Energy Monitor as an emerging leader in solar and wind energy, alongside Vietnam. Currently, the country has an operational large-scale solar energy capacity of 2.3 GW.
Aligned with its national renewable energy program 2020-2040, the Philippines aims to reach an installed capacity of 285MW by 2030, with interim targets of 5MW for 2025 and 2030. The government plans to strengthen this effort by adding nearly 2GW of solar capacity as part of the 4.16GW renewable energy projects planned for 2024.
Thanks to its progressive auctions, feed-in tariffs, net metering schemes, and tax incentives, the Philippines is positioned as the fourth most attractive emerging market for renewable energy. Another advantage is that the private sector dominates the market, unlike neighboring countries like Indonesia, where state-owned entities prevail. This approach facilitates smoother development processes through diversified resource allocation.
