The Holy Family Hospital, a missionary nursing home in Okhla will be the first private or non-government building in Delhi to have a large solar rooftop system, generating 300kW, according to an article on the India Times website.
The hospital is not entitled to any government subsidy on solar power and is yet set to make big savings on its total energy cost.
The hospital has 200 air conditioners apart from over a thousand electrical lights and other appliances. Its total energy needs are close to 900kW.
Under the power purchase agreement, the power company installs, operates and maintains solar panels on their rooftop and the hospital pays for the power generated and provides space for the panels. The power purchase agreement model is usually feasible only for large establishments.
"My estimation is that we will save Rs 3-5 lakh on our monthly energy bills. We will pay about Rs 7 per unit for solar energy as against Rs 9 per unit for conventional power that we have been paying," Fr P A George, director of Holy Family Hospital, said in the article.
