AHMEDABAD: Three public buildings in the city will use solar power to meet their daily energy needs by the end of the year.

Ahmedabad Municipal Corporation will have its south zone office in Maninagar, Memco sports complex and west zone office in Usmanpura using rooftop solar power. The purpose is to show Amdavadis that with high electricity prices, solar systems ensure handsome savings in the long run. The pay off period - time to recover investment in the power unit — can be less than two years, claim AMC officials.
