PM Surya Ghar Muft Bijli Yojana – 3 kW Solar System Project Report (Assam)
Introduction
The Government of India launched the to encourage residential rooftop solar installations across the country. Under this scheme, households can install rooftop solar systems with financial assistance from the Central Government and additional subsidy support from some State Governments, including Assam. The main objective of the scheme is to reduce electricity bills, promote renewable energy, and help households become energy independent.
A 3 kW on-grid rooftop solar system is one of the most popular choices for residential consumers because it can generate sufficient electricity for an average family and significantly reduce monthly electricity bills. Under the scheme, eligible consumers receive Central Government subsidy support up to ₹85,800 for 3 kW systems. Assam State Government also provides additional subsidy support, making solar installation more affordable for households.
