Recently, the world’s first 100% off-grid chilled water air conditioning system is being built with Thaisun monocrystalline solar modules at the distribution center of Multiaqua Inc in Easley, South Carolina. Multiaqua Inc is a world-leading manufacturer of chilled water air conditioning system and has more than 2500 distribution channels across the United States. This demo project uses 72 pcs of TSG60-280M solar modules and will provide enough electricity to the air conditioning system and make the system off-grid. This is not only a new function for solar modules, more importantly, it will have great contribution on household energy conservation and environmental protection. This new model of air conditioning system will be introduced to the world on the beginning of the next year. Thaisun will continue to work closely with Multiaqua to promote this new model and plant a greener future for the next generation.
