This paper presents experimental results obtained in a ultraviolet water disinfection system using a simple design, with accessible and low cost materials, using ultraviolet germicidal lamp powered by photovoltaics. The test results obtained confirm the mathematical model to obtain the maximum flow versus radiation dose needed to inactivate the microorganisms responsible for water contamination. Using the bacterium E. coli as an indicator of the quality of water, water disinfection efficiencies better than 99% were obtained. The photovoltaic system was designed to optimize the direct flow of energy, minimizing losses in the battery. This strategy, while increasing battery life, also significantly decreased the system losses and overall PV generator costs.
