The founder of the company has been working in offshore oilfield drilling for many years. Already in 1988 the worlds oil consumption to exceeded the new found oil fields and he decided to go into solar energy in 1990.

Immediately after the start up there were enquiries for refrigerating and air conditioning that can be combined with solar. The company founded as Transsolar in 1990 decided to develop a air conditioner that could work on solar energy. After 6 years of extensive research, development and field testing the air conditioner was ready for mass production. As the solar modules cost remained high, the company decided to focus on making energy efficient dc powered air conditioners for anti idling of trucks.
