Why Solar Works Here
Delhi receives an average of 5.1 hours of sunlight per day. With current electricity rates at ₹8.5/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.
