A typical 3 kW rooftop solar system in Trivandrum costs roughly ₹1.7–2.1 lakh before subsidy; homes can receive up to ₹78,000 under PM Surya Ghar, bringing net cost to around ₹1.0–1.3 lakh, and the system usually pays back in 3.5–5 years. KSEB net metering lets you offset your bill with your own generation.
Why solar works in Trivandrum
Trivandrum combines high electricity consumption in villas, apartments and offices with excellent sunshine of roughly 4–4.5 kWh per kW per day outside the monsoon. As Kerala's capital, it has a mature KSEB net-metering process and a large pool of empanelled installers.

Local installation tip
Mature trees and neighbouring buildings are the biggest yield risk in the city — insist on a written shade analysis. In coastal wards like Vettucaud, Valiyathura and Veli, choose salt-mist-rated modules and corrosion-proof mounting.
