The availability of sunlight converted into energy can be captured throughout the world. Since the 1990s the market for the use of solar energy has been growing, but information on case studies to assess the inclusion of solar water heaters in the popular Brazilian households are still scarce. The present work aims at contributing to reduce this gap and aims to assess the technical and economic feasibility of integration of solar water heaters in low-income households in the municipality Tremembé, located in the Paraíba Valley, State of São Paulo, Brazil. Tremembé has an area of 192 km ² and has a population of 42,027 inhabitants, with 10,632 households. The evaluation has done on a sectorial sample of total households. Effected through a stratified aleatory sampling plan, as this methodology allows better understanding the characteristics of each sector of the municipality. The field research was conducted with the survey method, with 360 questionnaires, which have been applied to a representative of each family. Images with descriptions and attributes of the official census sectors of IBGE have been treated in the extension kmz format. It was necessary to build a register in Excel to insert the data collected in the field and these data were overlaid on the images Leyers treated. The result of this research showed widespread acceptance of the population the possibility of facilities and use of solar water heating systems, especially the rural areas, mainly by presenting reduced cost of electric power in peak and points to reduced demand in the power grid. The research proves that with the use of solar energy, the city may save 31, 68 million kWh/year, which corresponds to R$ 9,504,000.00/ year
