In 2017 ''Sarvekshak'' became the 1st [[ship]] of [[Indian Navy]] ever to deploy [[solar power]]. It has innovatively deployed the zero-maintenance solar power system, capable of generating 5.4&nbsp;kW [[electricity]] and replacing the ship’s traditional 4.4&nbsp;kW emergency diesel alternator.{{citation needed|date=March 2022}} The installation cost was around Rs. 19 lakh and the generation cost is Rs. 12 per kv per hour. The estimated savings for a lifespan of about 15 years is around Rs. 1 crore. The current diesel generator consumes a litre of diesel to produce five units of electricity. Captain Rajesh Bargoti, the commanding officer of the ship, said It took about six months to put the entire system in place. We are now using [[solar energy]] for lights and a couple of [[air conditioners]].'<ref>{{Cite web| title=In A First, Indian Navy Installs Solar Power System On Its Survey Ship |url=http://topyaps.com/navy-installs-solar-panels-ship}}</ref> The estimated profit generated in a ship service life of 25 years is Rs 2.7 crore in this small project alone. "Even if the system is used for 25 days in one year, the system can repay its cost in less than 10 years while protecting the nature," the Navy said.

Indian Navy claimed that the 300-Watt panels will generate about 5.4&nbsp;kW solar power system, and avoid around 165&nbsp;kg of carbon a day, "So in its 25 years life the total carbon saved is around 15 lakhs kg and 5.75 lakh litres of diesel by this innovation" <ref>{{Cite news| title=INS Sarvekshak goes green; instals solar power system |newspaper=The Economic Times |url=http://economictimes.indiatimes.com/news/defence/ins-sarvekshak-goes-green-instals-solar-power-system/articleshow/57110554.cms}}</ref><ref>{{Cite web| title=Solar power lights up INS Sarvekshak |website=[[The Times of India]] |url=http://timesofindia.indiatimes.com/city/kochi/solar-power-lights-up-ins-sarvekshak/articleshow/57102784.cms}}</ref> Noting that the world is looking for clean, renewable sources of energy in order to protect and reduce the harm caused to the environment, the Navy said the deterioration of the environment is highly correlated to the production and usage of fossil-based fuels worldwide.

* The solar power generating system has been installed by customising and installing ‘razor-thin, flexible’ [[solar panels]] on the [[canopy (building)|canopy]] of its [[telescoping (mechanics)|telescopic]] (retractable) [[helicopter deck]].
* It has lightweight, extra-thin and flexible unbreakable solar panels imported from [[United States]] along with no-fume [[solid electrolyte]] [[Battery (electricity)|batteries]]. These industrial grade panels are found to be performing well in all-light conditions and are shade-tolerant. They also have a maintenance-free life for 24 years making it maintenance free.
