Indian scientists have designed a new device (设备) that

they hope will solve one of the biggest problems with the use

of solar energy. They call the device a solar tree. Solar trees

have metal “branches” (分枝). Each branch holds a solar panel (太阳能电池板). These panels have flat surfaces that collect energy from the sun and turn it into electricity.

Daljit Singh Bedi is the chief (首席的) scientist at the Council of Scientific and Industrial Research in India. Bedi says the shape of the solar trees makes it possible to fit more solar panels in a space than traditional systems do. This means less land would be needed to produce solar energy. “It takes about four square meters of space to produce energy. However, 400 square meters of space would be required in the past to produce the same energy,” he says.

Scientists believe the energy that a solar tree collects will be enough to power five homes. The solar tree will make it easier to provide solar energy for homes in cities. The trees will also take less space from farmers in the countryside. And that way people are able to use 10 to 15 percent more energy.

Amit Kumar is a senior engineer of the Energy and Resources Institute in New Delhi. He says that it is still not clear how useful these new developments in solar power technology are. “Only when we put those trees on a large scale (规模) will we be able to get that answer,” he says.

1Indian scientists have solved a big problem with the use of solar energy.

2Solar trees can save land and produce more energy.

3Not every scientist agrees that solar trees are useful at present.

4Solar trees are widely used in India.

5The passage mainly introduces how to use solar energy.
