WHAUP Solar Rooftop: Renewable and Green Energy Power Generation in Thailand

What is solar energy? How does it work? How is it made?

Solar energy is created via a photovoltaic system, where panels generate electricity through exposure to sunlight. This electricity is converted from DC (direct current) to AC (alternating current) power and supplied back to the power grid, or stored for later use.

Thailand’s policy on solar energy

Solar energy in Thailand has the potential for significant growth. It is a key renewable green energy for development, supported by Thai government policies. The solar energy market has been opening up for private investment, operations and innovation, including recent solar rooftop regulations. This will promote private electricity generation and trading, especially in industrial and commercial buildings.

Solar energy is a key feature in Thailand’s Alternative Energy Development Plan 2018–2037, which proposes a target of 34% renewable or green energy of total energy consumption by 2036.

The use of solar energy in Thailand’s industrial and service sectors

Solar rooftop installations are part of renewable energy solutions that can lower operating costs while at the same time contribute towards a greener environment.

By installing solar rooftop panels on industrial and commercial buildings, businesses can take advantage of larger surface areas to generate electricity from sunlight, supplying excess energy back to the power grid. Other buildings such as schools and hospitals, and those in the retail and service sectors with large roof space can also install solar rooftop panels for energy efficiency.
