Kathmandu, January 10:

Solar energy could be used to generate electricity which could help ease power crisis in urban areas, say experts.

Nepal Electricity Authority (NEA) from today will be increasing load shedding hours — six hours everyday which would add up to about 36 hours each week.

Dr Suresh Kumar Dhungel, a researcher on solar technology said, "This is an easier and environment friendly technology. Although the installation cost is a bit expensive, the urban populace, looking at various other expensive options, could afford it. The operating cost is negligible and once installed the system lasts for at least 20 years."

Small solar home systems have been installed in rural ares under various governmental programmes, but its use has not been noteworthy in the urban areas. "Due to lack of awareness about its benefits among urban people, this technology has been limited to the rural areas alone."

DK Shah, technical officer, Nepal Academy of Science and Technology (NAST), said a solar system of 1,000 Watts could provide enough en ergy to operate everyday home appliances for a family of five.

He added newer and better solar technologies are being developed. "If such technologies would be made available, we could avail of solar energy in easier and cheaper ways."
