With the aim of reaching carbon impartial by 2050, Thailand is pushing closely to decarbonize its vitality sector. Like many nations in SouthEast Asia, this implies lowering coal, oil, and pure fuel utilization and turning to renewable alternate options. Whereas Thailand is anticipating development from hydropower, wind, and biofuels, its most important anticipated development should come from the photo voltaic trade. As of 2021, there was an put in photo voltaic PV capability of two.9 GW. By 2037 the goal capability is 15.6 GW, dwarfing all different types of renewable vitality. 

Nevertheless, not all of those new photo voltaic PV tasks will likely be put in on land. The biggest floating hydro-solar mission on the earth got here on-line in Thailand in 2021, and its success has prompted the EGAT (Electrical energy Producing Authority of Thailand) to advance 15 new clear vitality tasks. The hydro-solar mission that got here on-line in 2021 totaled 45 MW and contains 145,000 panels, whereas the mixed vitality from the brand new tasks supported by EGAT will complete over 2.7 GW.

There are a number of distinctive advantages to floating PV tasks versus conventional land set up. Firstly, the photo voltaic farms don’t take up land that would in any other case be used for financial improvement. The choice to construct crops on water implies that the quantity of accessible land for companies, farming, or conservation will keep the identical at the same time as renewable vitality grows. Fairly than designating land for both photo voltaic set up or sources of financial improvement, Thailand will have the ability to develop its PV capability whereas supporting its rising economic system. 

Secondly, the water produces a cooling impact on the PV tasks, which improves panel efficiency by between 5-10%. Over the course of a mission’s life, this interprets to vital financial savings. Thailand may additionally reap the benefits of its current hydropower services to offer an excellent location for floating PV farms. Traditionally, hydropower reservoirs have been an excellent location for floating PV tasks and Thailand, with 2.7 GW of put in hydropower in 2021, definitely has viable reservoirs obtainable. Nevertheless, there are particular drawbacks to floating PV tasks that aren’t present in land-based tasks. These embody the wrestle to anchor tasks in a single place, which may develop into significantly necessary in deep water eventualities. 

The Asia Pacific Area, which incorporates Thailand, has the best floating photo voltaic market share, totaling 1.96 billion in 2022. This quantity is predicted to extend considerably by 2032. With an anticipated CAGR (compound annual development fee) of 16.5% over the following decade, this market share is predicted to achieve 26.5 billion. In fact, it isn’t reasonable to assume that Thailand will obtain its PV benchmarks utilizing solely floating photo voltaic farms. With the excessive ranges of PV radiation in lots of elements of the nation and the supply of land for development, floating PV farms could play an auxiliary position. Nevertheless, if Thailand reaches its objectives, floating PV farms will little question play some position. 

Different nations in SouthEast Asia may comply with the lead of Thailand with the hopes of diversifying their vitality choices. China and India have helped paved the way in floating photo voltaic, however it will likely be helpful to see a smaller nation adapt this new software to suit their vitality wants. Malaysia, with an vitality matrix made up of 47% oil and fuel and 32% coal, could possibly be a first-rate goal. International locations like Vietnam, which have already got excessive ranges of each photo voltaic and hydropower improvement, might be able to make the adoption of floating PV tasks easily. It’s thrilling to assume that over the following 20 years the panorama of Vietnam, Thailand, Malaysia could also be dotted with floating photo voltaic tasks.
