  • Photovoltaics: Basic Design Principles and Components

    If you are thinking of generating your own electricity, you should consider a photovoltaic (PV) system—a way to generate electricity by using energy from the sun. These systems have several advantages: they are cost-effective alternatives in areas where extending a utility power line is very expensive; they have no moving parts and require little maintenance; and they produce electricity ...

  • How do Photovoltaic Cells Actually Work?

    Solar power is an abundant renewable source that could be the solution to our future energy needs, but just how does a solar array produce the electricity that powers our lives? The short answer is that, through a solar panel, photons (light particles) are able to knock electrons off atoms and this causes a flow of electricity. The long ...

  • Fuzzy maximum power extraction control for a photovoltaic water pumping system

    AC loads present a delicate matter for photovoltaic systems, and this is because of the photovoltaic panel's operating point, which moves randomly according to irradiance changes; in this case, almost of photovoltaic water pumping systems use a DC–DC converter to ensure either the maximum power extracted from PV panel or the load needs. For AC motor pumps, an inverter must follow this chopper. ...
