According to IMARC Group’s report titled "Indonesia Solar Energy Market Size, Share, Trends and Forecast by Technology, Application, and Region, 2026-2034" the report offers a comprehensive analysis of the industry, including market share, growth, trends, and regional insights.

Indonesia Solar Energy Market Forecast

The Indonesia solar energy market size reached 598.9 GWh in 2025. The market is projected to reach 1,711.6 GWh by 2034, exhibiting a compound annual growth rate (CAGR) of 12.38% during the forecast period 2026-2034. This growth is driven by increased adoption of solar technologies, governmental support, rural electrification, and climate change mitigation goals. The report presents a thorough review featuring the solar energy market share in India, trends, and research of the industry.

Indonesia Solar Energy Market Growth Factors

• Government Policies and Renewable Energy Targets

The Indonesian government has issued a number of incentives‚ regulatory framework‚ and renewable energy targets to help grow the domestic solar energy market and encourage investors and industry players to be involved in solar energy projects with the goal of reducing dependence on fossil fuels and increasing renewable energy use․ Public and private partnerships have been encouraged to incentivize investment and expansion of solar energy use throughout the country․

• Declining Costs and Technological Advancements

The decreasing cost of solar has made it more affordable for both residential and commercial use․ The cost of solar panels‚ photovoltaic (PV) modules and other equipment to install and operate solar energy systems has decreased substantially over the past 10 years‚ largely due to technological advances and increased manufacturing․ Simultaneously‚ solar PV efficiency and system reliability are improving energy output which provides incentives for businesses and homeowners to invest in solar energy systems․

• Rising Energy Demand and Rural Electrification

In Indonesia‚ rapid population growth‚ together with rapid urbanization and industrialization‚ have resulted in accelerated electricity need‚ for which solar energy can provide a reliable sustainable solution․ Many rural areas and remote islands of Indonesia lack an electrical connection because grid infrastructure does not reach them․ To achieve electricity access in Indonesia and improve health and living conditions as well as stimulate the economy‚ decentralized solar systems such as mini-grids and off-grid solar home systems are being deployed․

Indonesia Solar Energy Market Trends

• Expansion of Solar PV and Rooftop Installations

The dominant trend in the Indonesia solar energy market is rapid growth in solar photovoltaic (PV) deployment․ Popularity in the solar energy industry is increasing with home‚ commercial and industrial rooftop installations․ Such systems help users generate their own electricity and reduce dependence on the conventional grid electricity․ The deployment of rooftop solar systems contributes to the overall renewable energy growth in the country․

• Growth of Large-Scale Solar Projects and Hybrid Systems

These large scale solar power plants are accompanying Indonesia's renewable energy infrastructure growth that has grown in recent years․ Most of Indonesia's large scale solar power plants are being built with BESS (Battery Energy Storage System) to improve the reliability of the power supply from solar energy․ Hybrid power plants that combine solar and other renewable energy sources‚ such as wind and hydropower‚ are being designed to address the problem of supply variability․

• Increasing Investment and Sustainability Focus

Investments into solar power projects in Indonesia from domestic and international players are likewise increasing as the private sector collaborates with government agencies within solar power projects and the renewable energy mix․ With rising awareness of environmental sustainability and the global climate change crisis‚ organizations and consumers are increasingly making the switch to cleaner energy sources․ Solar energy is seen as a major component of Indonesia's long-term energy security and carbon reduction policies․
