Following the early presidential election in June 2025 after the impeachment of the former president, a new government was established in Korea and national energy policy was redefined.
The new administration has positioned climate crisis response and energy security as central priorities. As part of institutional restructuring, the Ministry of Climate, Energy and Environment (MCEE) was established to integrate climate and energy policy functions and strengthen coordination for carbon neutrality and energy transition. The 2035 Nationally Determined Contribution (NDC) was also finalized, setting a greenhouse gas reduction target of 53–61% compared to 2018 levels.
Regarding the energy transition, the priorities are large-scale renewable energy expansion and the gradual phase-out of coal-fired power generation. The plan targets 100 GW of renewable energy capacity by 2030, focusing on solar PV and wind power. Solar PV deployment is expected to accelerate through regulatory reforms, including relaxed setback requirements and the expansion of agrivoltaics. Reducing generation costs remains a key objective, with long-term targets of approximately KRW 100/kWh for solar PV and below KRW 250/kWh for offshore wind.
Power system transformation is another key component of the policy framework. An AI-based “Energy Expressway” has been proposed to strengthen transmission networks and improve renewable integration. Korea also aims to transition towards a distributed power system based on local production and consumption, supported by region-based electricity pricing.
The 5th Energy Technology Development Plan (2025–2034) was established as a mid- to long-term strategy for energy technology R&D to achieve carbon neutrality and strengthen energy security.
Following the roadmap announcement in December 2024, the plan was finalized in 2025 after inter-ministerial consultations. It aims to accelerate the energy transition and enhance global competitiveness through renewable expansion, power system innovation, and clean energy technologies. Key areas include advanced solar and wind technologies, green hydrogen via water electrolysis, next-generation grids and energy storage systems (ESS), small modular reactors (SMRs), and distributed digital-based energy systems.
The solar PV roadmap focuses on strengthening competitiveness in next-generation photovoltaic technologies. Early commercialization of tandem solar cells is a key priority to secure ultra-high-efficiency PV and enhance global competitiveness. The roadmap also promotes expanded applications—including BIPV, floating PV, and agrivoltaics—supporting the transition to distributed energy systems. It further emphasizes digital-based O&M technologies to improve efficiency and reliability, along with lifecycle carbon reduction through recycling and circular economy approaches.
Following the new administration, the “Ultra-Innovative Economy” concept and the “15 Ultra-Innovative Leading Projects” were introduced to strengthen industrial competitiveness and future growth engines. Announced between September and November 2025, the projects are grouped into advanced materials and components, climate and energy sectors, and K-Boom-Up industries. They include power semiconductors, LNG containment systems, superconductors, graphene, specialty steel, solar and next-generation grids, offshore wind and HVDC, hydrogen and SMRs, as well as smart agriculture, fisheries, satellite applications, and K-industries (e.g., bio, content, beauty, and food). The initiative is supported by policy packages covering R&D, workforce development, finance, overseas expansion, and regulatory reform.

Within this framework, solar PV aims to strengthen industrial competitiveness through next-generation technologies. R&D is being intensified to achieve global leadership in tandem solar cell commercialization within five years, targeting approximately 35% cell efficiency and 28% module efficiency. The initiative also promotes value chain collaboration—materials, equipment, cells, and modules—to enhance technological self-reliance and industrial capacity.
CAST (KIER) also leads international joint research through a Korea–Switzerland program in collaboration with CSEM (Swiss Center for Electronics and Microtechnology), involving industrial partners Fluxim and TNETech under the “MetroPero” project. In addition, by utilizing its silicon solar cell manufacturing processes, CAST verifies the performance of domestically developed deposition equipment, thereby supporting exports through its role as a demonstration platform.

As of 2024, cumulative installed solar capacity in Korea reached 32 GW , of which 27.4 GW (approximately 86%) was accounted for by power generation businesses.
Residential installations represented 2.5 GW (8%), industrial and commercial applications 1.7 GW (5%), and other uses 0.3 GW (1%). By system size, approximately 14 GW (43.6%) correspond to systems of 100 kW or less, about 12 GW (38.1%) to systems between 100 kW and 1 MW, and around 5.8 GW (18.2%) to systems larger than 1 MW. These figures are based on Renewable Energy Deployment Statistics published by the Korea Energy Agency (KEA) and reclassified by application category. While power generation businesses dominate, small- and mid-scale systems still account for a significant share of total capacity, with systems larger than 20 MW representing only about 1.9 GW (approximately 6%).
Given current policy directions, evolving market structures, the 100 GW renewable energy target by 2030, and the Korea Green Transformation (K-GX), solar PV deployment is moving beyond simple capacity expansion toward rapid growth accompanied by structural transformation. Solar PV is increasingly positioned as a core component of the national energy transition. The 100 GW target represents a substantial increase from current capacity and requires a significant rise in annual installations. To support this, comprehensive measures—including electricity market reform, grid expansion, regulatory easing, and demand-side policies—are being implemented, signaling a shift from gradual growth to policy-driven acceleration. K-GX reinforces this transition by linking renewable expansion with industrial decarbonization, electrification, and grid modernization, positioning solar PV as key infrastructure for industrial competitiveness. The transition to a contract-based market is expected to improve investment stability and enable more planned expansion, supporting both large-scale and distributed systems. In parallel, grid enhancements will alleviate curtailment and congestion, while siting policies and community-based models diversify deployment and strengthen social acceptance.
Looking ahead, more detailed deployment pathways and targets will be presented in the forthcoming 12th Basic Plan for Long-term Electricity Supply and Demand (2026–2040). Overall, the solar PV market in Korea is expected to evolve into a dual-structure system, in which both large-scale and distributed installations expand under a contract-based market and grid-centered framework, with development strongly guided by policy planning.
