Why Solar Works Here
Chennai receives an average of 5.5 hours of sunlight per day. With current electricity rates at ₹7.5/kWh, switching to solar replaces a permanent rental cost (utility bill) with a temporary investment cost (solar system). After the 0.4-year payback period, your energy production is essentially free.
