In 2023, global solar panel production reached 612.0 GW, increasing 62.2% from the previous year. The top 4 manufacturing countries were China, who maintain the position of the world’s largest manufacturing hub, with 517.8 GW or 84.6% of global production; Vietnam with 20.8 GW or 3.4% of global production; India with 16.5 GW or 2.7% of global production; and Thailand with 14.1 GW or 2.3% of global production.

        The solar cell production in Thailand was approximately 5,255 MW, and the production of solar panels was approximately 11,600 MW. However, this assessment did not include inventory stocks.

        Solar panel manufacturers in Thailand included both joint venture operators between countries, especially investors from China, and domestic investors. According to data from 2023, major operators had the capacity to produce solar panels in Thailand with a total production capacity of approximately 10 GW per year (Table 2.1).

        Table 2.2 shows the survey results of inverter manufacturers for solar power systems in Thailand. In 2023, there were 6 inverter manufacturers: 2 companies from China, 1 company from Japan, and 3 companies from Thailand with a total production capacity of 10 GW. (Table 2.3).
