Photovoltaic solar air conditioning

 DC solar powered air conditioner – using solar panels as source of power. It can be used off-grid and grid-tied. The solar powered air conditioner combines the most efficient photovoltaic technology with DC engineered air conditioning innovation, to provide climate control that does not contribute to green house gas emissions and global warming. This air conditioner can replace the conventional type A/C.

 Solar thermal air conditioning

Active solar cooling wherein solar thermal collectors provide thermal energy to drive thermally-driven chillers. The solar thermal energy system can be also used to produce hot water.

There are multiple alternatives to compressor-based chillers that can reduce energy consumption by 80%, with less noise and vibration. Solar thermal energy can be used to efficiently cool in the summer, and also heat domestic hot water, and the building in the winter. These units are normally used for commercial and industrial applications where large space cooling is required.
