Vietnam’s rooftop solar policy is drawing a positive response, with industrial users, businesses and households all reporting tangible benefits. A machinery manufacturer said the scheme has significantly increased its renewable energy share, while a hotel operator is exploring installation to enhance energy independence and reduce long-term electricity expenses. For households, daytime electricity bills have fallen noticeably.

Energy expert Ha Dang Son noted that rooftop solar offers relatively short payback periods, making it well aligned with Vietnam’s current policy direction.

What is Vietnam aiming for with its rooftop solar push?

In late March, former Prime Minister Pham Minh Chinh signed Directive No. 10/CT-TTg, calling for nationwide energy conservation and encouraging rooftop solar deployment. The government aims to increase annual installation rates of self-consumed rooftop solar by 10% for both public institutions and households, while targeting rooftop solar to account for 20% of planned capacity across provinces and cities by 2030.

Unlock the full article to explore three key takeaways:

1. The Vietnamese government requires provinces and cities to achieve 20% of planned rooftop solar capacity by 2030, with annual installation rates rising 10% for both public institutions and households.
2. Businesses and households are already seeing results: A machinery factory in Bac Ninh reports a higher renewable energy share, while households in Thanh Hoa say daytime electricity bills have fallen noticeably.
3. Thailand plans a budget of up to THB 500 billion (~USD 15.4 billion), part of which will provide preferential loan rates for rooftop solar installations, aiming to accelerate the shift away from fossil fuel dependence.
