Vietnam

A Vietnamese research team has developed a low-cost passive cooling system for PV modules based on hydrogel-coated paper that combines water flow and interfacial evaporation to reduce operating temperatures. Outdoor tests showed temperature reductions of up to 14 C and efficiency gains of up to 16.8%, with stable operation achieved using both freshwater and natural seawater.

Figures from the International Renewable Energy Agency state that Vietnam’s cumulative solar capacity reached 19,252 MW by the end of last year, indicating a 586 MW increase in 2025.

Wood Mackenzie’s latest analysis explores how 13 of the world’s leading power markets are impacted by the current fuel crisis, with those most reliant on fuel imports facing the greatest risk exposure. The consultancy says the average cost of generation is set to increase by $2.30/MWh across these 13 markets if a de-escalation of the conflict enables fuel price moderation in the latter half of 2026, increasing to an average of around $8.30/MWh if current elevated price levels persist through the year.

JinkoSolar has formally terminated its 4 GW Hai Ha solar cell project in Vietnam, citing US antidumping duties that undermined its export economics. The company will maintain other Vietnamese operations while shifting focus to localized supply chains and Asia-Pacific and Middle East markets.

The facility will produce solar wafers for the U.S. market.

A draft decree from Vietnam’s Ministry of Industry and Trade is proposing rooftop solar owners could sell up to 50% of the energy produced back to the grid, in a bid to increase future uptake.

Households in Vietnam could receive up to VND 3 million ($113.9) in investment capital for home solar-plus-storage systems installed for self-consumption, or a preferential loan of up to VND 40 million, under proposals from the country’s Ministry of Industry and Trade.

South Korea’s OCI Holdings is entering the solar wafer business with a majority stake in a wafer plant in Vietnam valued at $120 million. The facility will produce solar wafers for the U.S. market.

The International Energy Agency (IEA) says the cost of capital for solar remains higher in Southeast Asian countries than it does in other emerging and developing economies.

The International Energy Agency’s latest report says solar and wind energy are well placed to meet Southeast Asia’s growing electricity demand. It adds that while additional deployment will create flexibility challenges, most countries in the region can integrate more solar and wind energy without requiring major system changes.
