Photovoltaic power generation system for housing units.(Sharp Corp. (Japan))(Brief Article)

Sharp Corporation has developed a photovoltaic power generation system for housing which uses a large 155 sq mm solar cell and can readily be adapted to roofs of various shapes.

The company says this is the first storage converter incorporating a voltage regulation function that easily enables installation on any existing power system. The unit also has a built-in power conditioner, convenient for the user, and is available in a lineup of various models to meet specific user requirements.

The system consists of the photovoltaic cell module, a power conditioner, a storage converter and associated cables. A rack and ancillary interconnections will be required for installation.

The photovoltaic module is available in a range based on the single-crystal cell NT Series of 1) the existing 125 sq mm size, 2) the polycrystalline cell NE Series, and 3) the latest 155 sq mm polycrystalline cells.

The output of a module is 151 W, and a standard 3-kW system consists of 20 modules.

The storage converter is different from conventional counterparts and is available it photovoltaic cell module voltages with different numbers of series connections, depending on specific system units, to permit input into power conditioners. There are two versions available, one with a voltage boost ratio of 1.15-2.0, and the ...
