Solar powered car air-conditioning
Turn off the car but keep the AC on !
The roof of your car is the most under-utilized area in your car. Install it with solar panel that can produce about 80 watts of energy sufficient to power your car’s air conditioner.
A medium sized saloon has about 9sqft of roof space to install solar panels. These panels could cost approximately Rs. 6,000 in India and will be sufficient to run the existing Air Conditioning unit of a Maruti Esteem.
Additionally having another layer on top of the car’s roof provides great insulation from sunlight.
It is possible to have an independent roof mounted air-conditioning unit in addition to the pre-installed unit. The roof surmounted unit should cost Rs. 13,000. You’ll also require two additional batteries and a voltage regulator.
So you have a place to sleep during power cuts, becuase a fully charged unit can run the air conditioning to 1.5 hours continuously. If used with a thermostat auto-switchoff, it could keep your car cool for 5-6 hours.
Save fuel, by reducing the load on your engine and running the AC from the solar energy.
