Indonesia's solar energy sector seeks wider support for growth

Indonesia's solar energy sector is poised for significant growth but requires comprehensive support across multiple fronts, including policy, investment, financing, technology, industry, and human resources. This was a central theme at Indosolar 2026, held in Jakarta from August 19-20, 2026, alongside the Indonesia Sustainable Energy Week (ISEW) 2026.

The event, themed “Building the Future of Indonesia's Solar Energy,” focused on identifying "quick win" opportunities to develop up to 10 gigawatts (GW) of solar energy capacity by 2028. Mada Ayu Habsari, Chairperson of AESI, emphasized the need for a robust ecosystem to match the ambitious renewable energy targets outlined in the 2025-2034 Electricity Supply Business Plan (RUPTL). She stressed that the large market potential must translate into bankable projects ready for immediate construction, highlighting that a more connected ecosystem will accelerate solar energy implementation.

With an increasingly connected ecosystem, we can drive more bankable projects and accelerate the implementation of solar energy in Indonesia.

Discussions at Indosolar 2026 covered critical aspects of the solar industry's development. These included the national roadmap for accelerating solar energy deployment, opportunities for rooftop and floating solar power plants, and the utilization of microgrids and hybrid systems to support the de-dieselization of areas lacking grid access. The forum also addressed strengthening the national supply chain and enhancing the competitiveness of the domestic solar industry, alongside exploring independent power producer (IPP) schemes, cross-border solar electricity trading, and investment prospects.

Furthermore, the integration of solar energy with industrial and digital economy needs was highlighted, particularly through rooftop solar installations in industrial estates and powering green data centers. Atiek Puspa Fadhilah from GIZ Indonesia & ASEAN noted the necessity of close cooperation between the government and market stakeholders for clean energy transitions. The event also facilitated business-to-business connections through an exhibition and collaboration hub, bringing together developers, EPC companies, consultants, financial institutions, and technology providers. AESI also focused on workforce readiness, partnering with JA Solar, Xingtai Polytechnic Institute of New Energy, and ATW Solar for training programs and a policy competition to cultivate skilled personnel for the growing solar industry.

Energy transition requires strong relationships between policymakers, investors, technology providers, and industry players.
