Titan Power Grid, based in Hyderabad, India, offers Solar Power Plant with Solar AC, among other solar-based products/solutions. I met their representatives at the recently concluded HYREX 2015 Solar Expo at Hyderabad.
This is the Solar AC they had displayed in their stall. It seems they make the Solar AC in association with SHARP. As you can guess, the Solar AC uses Inverter AC technology that can adjust the speed of the compressor based on the ambient air temperature which results in lower energy consumption/energy bills, and quieter operation.
But the Solar AC developed by Titan Power Grid, the company representatives say, is more efficient than Inverter ACs because they use more energy efficient parts and power the motor, compressor, fans, etc. through solar. Hence, their 1 Tonne AC is rated at 560W that can be provided by 600W Solar Panels, which is lower than the 1000W+ power rating of normal ACs (according to their website).
They provide three options for Solar AC:
- Stand-alone energy efficient Solar AC that is not powered by Solar Panels.
- Solar AC powered by Solar Panels and with AC Synchronization Controller to enable the AC to be operated with Solar power or Grid.
- Solar AC with Solar Panels, AC Synchronization, and Batteries to enable the AC to be operated with Solar Power, Grid or Saved solar power in the batteries.
Also, have a look at their excellent guide (pdf) explaining the basic components that go into the making a solar power plant.
