- Large and Medium-Scale Absorption and Adsorption Chillers are available since several years and used for Custom-Made Systems

- First Small-Scale Thermal/ Solar Cooling Kits are on the Market

- Huge Market Potential for Solar Cooling and Refrigeration

- First Solar/ Thermal Cooling Associations Founded (Green Chiller, ausSCIG)

- Specific Collector Surface of the chillii® Solar Cooling Kits is 4.5 m²/kW (Average Value of Market Available Solar Cooling Kits in Europe is 4.2 m²/kW)

- Specific Costs of Solar Cooling Kits in Europe(*):- 5,000 to 8,000 EUR/kW in 2007 - 4,000 to 4,500 EUR/kW in 2008- 3,500 to 4,500 EUR/kW in 2009

(*) The solar cooling Kit consist of solar thermal collectors, hot water storage, pump-set, chiller, re-cooler, partly cold water storage and system controller. The specific costs are without cold distribution and installation costs.
