Solar power in ASEAN: Market and M&A updates, highlights and
Ceiling prices for solar were set at 4.4043 PHP/kWh (around 0.077 USD/kWh) for ground-mounted, 4.8738 PHP/kWh (around 0.086 USD/kWh) for rooftop, and 5.3948
Solar module prices are influenced by geopolitical factors, technological advancements, and shifting consumer preferences. Recent data highlights a bifurcation in pricing dynamics: modules with cells from Southeast Asia (tariff-affected) saw a 7.7% price increase (November 2024–February 2025), while non-Southeast Asian modules declined by 0.8% 6.
Many countries in the ASEAN region have adopted this rooftop solar system idea and the demand is continually increasing thanks to its potential long-term benefit in reducing the electricity cost (Fig. 6). Moreover, rooftop solar systems become a timely and resource-efficient way for the countries to meet it's renewable energy goals.
In the ASEAN region total installed capacity of floating PV was below 1 MW till 2019, but large-scale floating PV module installations grew rapidly in Indonesia, Singapore, Thailand, Malaysia, and Philippines from year 2020 and onwards.
Regardless to the system, optimizing the use of solar rooftops is a great way to generate clean energy thus achieve renewable energy goals. For those reasons, governments across the region (ASEAN) needs to maintain appropriate policy and regulation to boost the installation of rooftop solar systems. 2.3. Floating PV module
