Which Solar System Is Right for a 1BHK, 2BHK, 3BHK, or Shop?
Share
Confused about which solar system size you need for your home or shop? You're not alone. One of the most common questions buyers ask before purchasing solar is: how much capacity do I actually need? This guide breaks it down by home size so you can make a confident, informed decision.
Why Solar System Size Matters
Buying an undersized system means your batteries will drain quickly and you won't cover your daily electricity needs. Buying an oversized system means you're spending more than necessary. Getting the right size saves money both upfront and over the lifetime of the system.
1BHK Home – 1kW to 2kW Solar System
A 1BHK flat typically runs 3-5 lights, 2 fans, a TV, and a small refrigerator. Total load is usually between 500W and 1kW.
- Recommended system: 1kW On-Grid or 1kW Hybrid
- Panels required: 3-4 panels (330W each)
- Battery (if off-grid): 100Ah Lithium or 150Ah Tubular
