It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solardepending on the way they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.

Thailand as a whole has great solar potential, but especially the southern and northern parts of the northeastern region of Udon Thani Province and certain areas in the central region. The combined solar potential areas account for around 14.3% of the country’s overall area.
