The New Town Kolkata Development Authority (NKDA) has installed over 700 “intelligent” solar lights along 24 streets across New Town. The move is expected to reduce the electricity bill by Rs 3 lakh per year.
The solar panels fitted with sensors enable the lights to automatically switch on when the sun sets. Also, the intensity of the street lights reduces after a set time, which is currently configured at 10pm.
Officials said the solar power is stored in fixed-use lithium batteries that have long life span with no maintenance and are safe and efficient.
