Rooftop solar power is proposed as the main prong of state efforts to promote clean energy.

Thailand's clean energy development was discussed at a recent state-private sector meeting, and can be successfully implemented if the nation focuses on solar power, according to an energy official who requested anonymity.He said Thailand's solar sector offers opportunities across all scales, from micro-installations producing just a few kilowatts to gigawatt-scale projects.

This flexibility allows investments ranging from small households and micro-businesses with limited capital to billion-baht ventures by large corporations.

A study by the Department of Alternative Energy Development and Efficiency estimates Thailand has the technical potential to generate nearly 1,000GW of solar power nationwide.

The declining cost of battery energy storage systems (BESS) enables this transition, said the official.
