Bangkok, Thailand, has Officially Launched Its "Bangkok Solar City" Program, Encouraging Rooftop Solar Installations

The Thai government is systematically advancing its energy transition from multiple dimensions, including policy, technology, and public welfare, with residential solar power being a key component. Thailand has recently introduced a series of important initiatives in the residential solar power sector, aiming to reduce household electricity costs and drive the country's energy transition.

Promoting Local Manufacturing: To reduce equipment costs, the Thai government is strongly supporting the production of domestically developed solar equipment. For example, it has approved the mass production of a domestically developed 5000-watt solar inverter and plans to establish several regional assembly centers, aiming to achieve an annual production capacity of 500,000 units.

Clear Energy Goals: These residential solar power initiatives serve Thailand's broader energy transition strategy. The government is developing a new National Power Development Plan (PDP), one of the core objectives of which is to ensure that the public has genuine access to clean energy. Previous draft plans proposed increasing the share of renewable energy in electricity generation to 51% by 2037.

Pay attention to policy developments: It's important to note that, in response to overcapacity in some industries, the Board of Investment (BOI) of Thailand has suspended new investment incentives for the solar cell and panel manufacturing industry since 2025. However, this primarily affects large-scale production investments, not ordinary residential rooftop solar installations.

Overall, Thailand is promoting the widespread adoption of residential solar power through strong policy support and economic incentives. These measures not only make solar power affordable and accessible to the public, but also allow them to generate income through electricity sales, creating a virtuous cycle.
