INS Sarvekshak 1st Indian warship to use solar energy
Navy's survey-class vessel INS Sarvekshak has become India's first warship to install solar panels on board. The Navy said the system was 100% reliable and could be used for communication equipment, battery charging and general lightings. It was "maintenance free" whereas the diesel generator requires regular maintenance, it added. Notably, the system would save 22,995 litres of diesel annually.
