Hospitals both in urban and rural areas consume a lot of energy throughout the day as the electrical equipment used directly or indirectly to treat patients require uninterrupted power. Many hospitals have considerable unused rooftop space. Combined with power shortages and rising cost of diesel, rooftop solar power makes a compelling case for implementation in hospitals; there are several advantages but also several constraints that need to be considered when deciding on and designing a rooftop solar power system for a hospital, such as using a variable source of power like solar to power equipment used in life saving situations.
