Residential Photovoltaic Power Generation System
(High efficiency PV Module & Multi-power Conditioner)
Winner
Sharp Corporation

The conversion rate of multi crystalline solar cell module has raised to the industry's highest level of 16% by improving the production process.
A voltage booster of the multi-power conditioner, which is the first achievement in the Japanese industry, made various modular configurations available.
The combination of the module and the power conditioner can provide for a larger electric power supply compared to the conventional system.
This is expected to contribute to further dissemination of the residential photovoltaic power generation system.

Features of Equipment, Systems and Facilities
  • High efficiency polycrystalline solar cell module (NT-K136A)
    The exclusive technology on crystalline growth produced a high quality poly-crystalline wafer which achieved the industry's highest 16.0% conversion rate for polycrystalline type (136 W/module).

  • Multi-power conditioner (JH40EK)
    The power conditioner converts the power generated by solar cell from DC to AC and sends them to the power grid. Conventionally, before the power flows into a power conditioner their voltage is adjusted by a fixed number (in general eight) of PV modules in series. When a certain number of modules cannot be installed on the roof, their voltage cannot be equaled to the other. Due to this voltage difference feasible power cannot be expected. Therefore, extra space on the roof could not be utilized effectively in case of conventional systems. The multi-power conditioner solved this problem. It provides a voltage booster and the voltage level will be adjusted to the other lines of modules. A series of different numbers of modules can output the power with the same voltage. The system can produce the maximum amount of the power according to the roof space and roof shape.

    Taking less space for installation
    The combination of the high efficiency solar cell module and multi-power conditioner increased the system capacity within the limited space.
