Solar Cell

Solar rooftops generate electricity using solar energy. Solar cells are installed on rooftops, residential homes, industrial factories, outdoor parking areas or department store buildings. When solar cells receive solar energy, energy enters the inverter and solar cells can be used with almost every type of electrical equipment.

Solar rooftops have the following advantages:

ㆍSolar cells can block sunlight and reduce roof heat along with air conditioner burdens.

ㆍSolar cells reduce electricity costs by generating electricity and extending useful life of lighting equipment.

ㆍSolar cells do not use any fuel apart from sunlight, which is clean energy.

ㆍSolar cells do not create waste during use and have no combustion, resulting in no pollution emissions that damage the environment.

Furthermore, solar rooftop trends are rising because solar rooftops use renewable energy and costs such as the cost of solar cells or other accessory equipment are declining gradually.
