Question

C

Indian scientists have designed a new device* 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*” which are just from a tall pole at different levels. Each branch holds a solar panel*. These panels have large metal boards that collect energy from the sun and turn it into electricity.

Daljit Singh Bedi is the main 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 which may need 400 square meters of space,” he says.

Scientists believe the energy 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 rural areas. Bedi says solar trees will collect more energy than normal solar panels on the tops of buildings. “This design makes the solar panels exposed* more towards the sun,” he says. “And that way people are able to use 10 to 15 percent more energy.”

India has promised to reduce its greenhouse gas production. The country’s promise depends heavily on increasing solar energy. The cost of solar panels has gone down in recent years. This has increased the possibility of applying*solar trees in India.

Amit Kumar is the senior director of the Energy and Resources Institute in New Delhi. He says gaining access* to land takes time and increases costs. He adds 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* will we be able to get that answer,” he says.
