The sun has an extremely important role in the existence of human beings, and Brazil has a privileged geographical position to explore sunlight. The union of these two factors favors the use of solar cells for converting solar energy into electricity by photovoltaic technology: it is a great alternative energy source, especially for being a clean one, causing less damage to the environment. This paper addresses the photovoltaic technology with a focus on hospitals, through case studies found in international literature, because hospitals, even running all important services to society, have a potential for pollution capable of causing damage to human health and the environment that is around them. It is estimated that the Brazilian oil reserves are sufficient for twenty-two years. This makes the search for alternative sources for power generation a necessity.
