I recently had a detailed conversation with the team from one of the solar vendor regarding solar power installation for my home, and I wanted to share the insights I gained. Key Questions I Asked and Their Responses: 1. ROI (Return on Investment) This was my top concern since Bangalore has around three months with minimal sunlight. I asked how feasible it would be to recover my investment in a reasonable period. Their response: They assured me that even with reduced sunlight during certain months, a 1 kW system would generate a minimum of 4 units per day on average. My calculation: On average, my electricity bill comes to around ₹2,500 to ₹3,000 per month. Units consumed: ₹2,750 (average bill) / ₹7.50 (rate per unit) = ~367 units per month Solar generation and excess units: Assuming 1 kW generates an average of 6 units per day (since we occasionally go on holidays), a 3 kW system would generate: 3 kW * 6 units/day * 30 days = 540 units per month Excess solar power earnings: Of these, ...

As more households shift toward using inverters and UPS systems for uninterrupted power during outages, it becomes essential to understand how to calculate the right load for your home and ensure you invest in a system that meets your power needs efficiently. Let’s take a closer look at how to determine the right inverter load and battery capacity, using a typical household setup as an example. 1. Calculating the Power Load for Your Home To begin with, we need to identify the total power requirement of the appliances we want to run during a power outage. This involves listing each appliance, along with its wattage, and then calculating the total load: Kitchen: 4 LED lights, each consuming 40 watts = 160 watts Living Room: 6 LED lights, each consuming 60 watts = 360 watts Master Bedroom: 6 LED lights, each consuming 60 watts = 360 watts Television: 1 unit consuming 180 watts = 180 watts Fans: 4 units, each consuming 75 watts = 300 watts Refrigerator: A standard fridge typically runs on ...
