Photovoltaic water pumping systems based on standard components
| Resumo: | The depletion of fossil fuels and their rising prices, increase researches in renewable energy sources. Furthermore, about 11.4% of global population (822 million people) lack basic drinking water service. Thus, photovoltaic water pumping systems (PVWPS) are an interesting solution to provide water in remote areas, which nowadays mostly of the systems are diesel based. PVWPS are commercially available as integrated sets of components, using a pump with a motor and a controller. Normally, small or very small companies are those who install these systems. They are dependent on the system itself and on the manufacturer. The only benefit of this companies comes from the installation they provide to the end user. Since they are not able to develop their own systems. This work presents different strategies for photovoltaic water pumping systems based on standard frequency converters, which are off-the-shelf and widely available, for different power levels. A new approach for low power applications is proposed, using only one or two photovoltaic modules, a centrifugal AC pump driven by a standard frequency converter. These approaches are valuable for small companies to develop their own cost-effective solutions. |
