Features of equipment, system and facilities

As the use of residential PV systems expands, there is a growing need for designs that enable installation on roofs that are more complex in shape, such as hip roofs, and that can generate maximum power in a limited roof area. In the light of such market trends, and to further promote the spread of residential PV power generation, Sharp Corp. designed and commercialized a PV power generation system for gable and hip roofs.

Solar cell modules for both gable and hip roofs (ND-145BC, ND-072BR/BL)

Sharp improved the system design and installation efficiency by adding to its product lineup triangular corner solar cell modules for hip roofs with a 1/2 pitch.

Power conditioner with graphic remote control (JH-SO1, LO1, MO1)

The power conditioner converts the direct current (DC) power from solar cells to alternating current (AC). The display panel shows the system power generation pattern graphically. This graphical display of the day’s power output in hourly readings gives a clear visual confirmation of how the system has operated, even during the night when the system has stopped.

String converter (JH-X2B, X4B)

A string is several solar cell modules connected in a series. When solar cells are connected to a power conditioner, they must be connected in a series of a set number of modules (standard number of 9–12) to maintain a consistent voltage. This string converter adjusts the voltage of strings with fewer number of modules in a series to that of the standard number.
