Renewable Energy – Solar (PV)

Power Supply Options


Stand-Alone System Module

Rechargeable batteries are integrated into the PV system for power storage and stabilization.

Location: Mountains, islands, base station, areas where public grid is not connected




  1. PV generates power for loading and recharging batteries during the day.
  2. Batteries provide electricity during the night.
  3. The system is self-sustainable when collocating with storage batteries and grid.


Hybrid System Module

The system supplies power to the grid during the day, then draws power for the grid at night. In case of power interruptions, the hybrid module can draw power from integrated batteries.

Location: Islands or remote areas



  1. Utilize regional characteristics of the complementary power generation between PV and wind power to reduce costs of solar cells, wind turbines, and storage batteries.
  2. Hybrid PV-Diesel system assures stable power supply under situations such as lack of sufficient sunlight, wind or stored power of batteries.
  3. Hybrid PV-Diesel system allows upgrade of the diesel generators’ power generation efficiency, and prolong supply and maintenance period.


Grid-connected System Module

To be connected to the electrical grid in case of power shortage or output fluctuations.

Location: Grid-connected areas (use as auxiliary power supply)




Development of renewable energy – particularly solar technology, has been receiving increasing attention for the purpose of lowering of costs and reducing energy reliance.

A typical solar photovoltaic cell applies P/N type semiconducting materials to form two (positive and negative) electrodes.
