PM Surya Ghar :
Muft Bijli Yojana
The PM Surya Ghar: Muft Bijli Yojana, inaugurated in 2024, is a significant government initiative designed to ensure free electricity for one crore Indian households. The scheme provides financial assistance through subsidies of up to 40% for the installation of rooftop solar panels, along with the provision of collateral-free financing. Economically, the initiative is anticipated to yield annual government savings of approximately ₹75,000 crore in electricity expenses.
What do we offer?
Radius by Rishabh aligns with this Yojana by manufacturing single-phase inverters (iUNO) 100% made in India and supports this initiative of Indian government. These inverters are the heart for the solar roof top installation, as without them, the conversion of the DC power to AC will not happen and generated power would be of no use ahead.
