Inverter For Clean Solar Electricity

ABB's PVS800 central inverter is available in power ratings of between 100 and 500 kW and can be used in both industrial-scale photovoltaic power plants and for medium-sized power plants installed on the roofs of commercial or industrial buildings. Photovoltaic plants, in which solar energy is collected by light-sensitive panels and converted directly into electricity, rely on inverters to convert the direct current produced by the cells into alternating current, which is needed for electricity distribution.Photovoltaic energy is currently more expensive than conventional, higher-carbon energy sources, but it's getting cheaper. Over the next five years, as photovoltaic module production capacities continue to grow and economies of scale are achieved, the cost of photovoltaic-based power generation is expected to fall to the same levels as peak-rate electricity from conventional sources.The new solar inverters are based on ABB's technology developed for use in variable-speed drives (devices that control the flow of power to electrical equipment, tailoring performance to the needs of the task in hand). www.abb.com
