An upsurge in domestic use of new energy

Update Time:2014-09-04 15:59

A new installation at a home in one of China's largest ports could herald an upsurge in domestic use of new energy, as Zhao Yinan reports from Tianjin.

Dong Qiang's neighbors have suddenly become very friendly. Although the 38-year-old knew his neighbors by sight, they have never before paid him a visit. Now, however, they have started to descend on him in droves.

The reason? The "big screens" Dong recently installed on his roof.

The "big screens" are photovoltaic, or PV, cells that generate electricity for domestic use by harnessing solar power. Each panel is roughly the same size as a four-seater dining table and Dong expects the system to reduce his carbon emissions by as much as five metric tons every year.

It's little wonder that Dong's new appliances have attracted so much attention: several silicon batteries affixed to the roof mean the house, in Tianjin's Binhai New Area, stands out among the other dwellings in the area.

He also is the first resident of Tianjin, a harbor city in Northern China and one of the country's four municipalities, to decide to go green on the roof of his own home.

In today's climate of growing energy needs and increasing environmental concern, alternatives to the use of non-renewable and polluting fossil fuels have to be investigated. One such alternative is solar energy.Solar panel transfer the sunshine to electronic power, and the power will be saved at the battery. The transferred efficiency of monocrystalline solar panel is about 15%, sometimes up to 18%. This is the highest performance now. As the cost is very high, so it could not widely use. And the monocrystalline solar panel is make of tempered glass and waterproof resin, strong and durable, working life is 15 years, some product could up to 25 years.
