Photovoltaic system

The photovoltaic system comprises a solar battery module and an inverter for converting the direct current (DC) voltage generated from the battery to an alternating current (AC) voltage. The system is capable of directly converting the energy of sunlight into electricity.

Solar-powered house

- A solar-powered house refers to a residential building installed with the solar battery modules on its rooftop and windows to directly take advantage of the electricity generated from the module.
- A household can receive governmental support for installing the solar-powering equipment which generates 3kW or less electricity. An approximate area of 23妊 is required.

Effect of solar-powered house

- The efficiency of a solar-powered house is highest when the solar panels of the module is installed to face the south, as the influence of shade decreases. Because the billing of electricity in residential buildings follows the progressive stage system, households with more electricity consumptions are bound to benefit from the photovoltaic system.

- Example

< Assuming that the monthly power consumption is 450 KWh >

Advantages of Solar-powered house and exemplary case

– Infinite source of energy without pollution and cost for fuel
– Environmental-friendly energy without mechanical vibration and noise
– No maintenance cost regarding management and operation after the installation
– Electric charges saved by the energy production of photovoltaic system
