Equipment constituting photovoltaic power generating system

Solar cell

This is a device in which solar radiation energy from the sun is converted to direct current electric energy. We propose an optimal solar battery according to customer’s installation conditions, including polycrystalline solar cells providing high cost-effectiveness and CIGS solar cells, which are resistant to shadow and have increased transformation efficiency rapidly in recent years.

Connection box and current collecting box

This is a device that collects wires from the solar cell and connects to the power conditioner effectively. In recent years, demand for connection boxes equipped with a string monitor that monitors the status of solar cells is increasing. The connection box has the role of performing selective trip, which interrupts only sites where an accident has occurred in the case of an accident.

Power conditioner

This is a device that converts the direct power from the solar cell to AC power for system interconnection. The power conditioner needs to be highly efficient. In addition, monitoring system status and advanced communication functions are important roles of the power conditioner.

step-up transformer

This is a device that boosts 400 V series electric power output from the power conditioner to 6.6 kV. In recent years, demand for the top-runner type having high transformation efficiency has been increasing.

Power receiving facility

This is a facility equipped with a protective device required for connecting to commercial systems and isolating the circuit in case of accident. This facility also plays the role of supplying the required electric power during periods when no electric power is generated, including night time.
