Haryana Government has decided to install hybrid solar systems in all government schools of the state in a phased manner.
To begin with, the hybrid solar systems would be installed in 3,222 government high and senior secondary schools at a cost of Rs 236.57 crore, said Haryana Education Minister Ram Bilas Sharma.
The hybrid solar systems generate power in the same way as a common grid-tie solar system but use batteries to store energy for later use.
Sharma said that hybrid solar systems to be installed in the schools would have a battery bank of 7.2 VAh/Wp so as to ensure that uninterrupted power is available in schools after installation of solar system . He said that the central assistance of 30 per cent which is on reimbursement basis would provide assistance in fulfilling the gap of the additional burden of Rs 110 crore to provide the battery bank.
Moreover, any amount which is left after installation of hybrid solar systems in all the government schools and receipt of central assistance would be used for operational and maintenance, upgradation and replacement of consumer items (battery) considering the fact that the solar panel would be having a warranty period of 25 years and the power conditioning unit (PCU) and batteries would be having a warranty of five years after successful commissioning, he added.
