A 1kW solar system in India typically generates 3.5–5 units per day — but the real output depends on location, system efficiency, and weather. In this guide, I share actual 22-day performance data from my 5kW system, along with a simple method to calculate accurate solar generation for your home.
Rooftop solar can significantly reduce electricity bills in Bihar. This analysis explains the cost, savings, payback period, and long-term financial benefits of installing a 5 kW rooftop solar system in Bihar.
Solar installers and websites often promote “average solar savings” to explain the benefits of rooftop solar. But in reality, solar economics depends on several factors such as solar radiation, electricity tariffs, and system cost. In this article, we explore why average solar savings can be misleading and how homeowners should evaluate solar using financial metrics like payback period, IRR, and NPV.
Many solar payback calculations assume exported units equal imported electricity. Under net billing, export tariffs are often lower, reducing the real value of solar. This article explains blended solar rates, export-heavy distortion, and how tariff escalation affects long-term ROI — so you understand your true payback, not an optimistic projection.
