3 kW vs 5 kW On-Grid System: Proposal Comparison
Both 3 kW and 5 kW systems qualify for the full ₹1,08,000 subsidy in Chhattisgarh. Notice how 5 kW generates ~80% more energy with faster return on investment:

1 kW to 30 kW Solar Systems: Output, Panels, Cost & Savings
As an engineering rule of thumb, each 1 kW produces 4 to 5 units daily. Review estimated output and bill reduction below:

2 ACs, 4-5 Fans, TV, Fridge, Lights, Water Pump, Cooler, Washing Machine, Motor
2-3 ACs, 5-6 Fans, TV, Refrigerator, Lights, Pump, Cooler, Washing Machine, Geyser, Motor, Battery Inverter
3-4 ACs, 6-8 Fans, TV, Refrigerator, Lights, Water Pump, Cooler, Washing Machine, Heavy Motors, Commercial Equipment
Which Inverter Architecture Fits Your Needs?
Compare the three core inverter topologies to choose the best combination of capital cost, battery backup, and net metering:
1. On-Grid (ग्रिड टाइड)
Best for areas with reliable grid power looking to eliminate electricity bills. Surplus energy is exported via bi-directional net metering.
- कम शुरुआती लागत (बैटरी की जरूरत नहीं)
- PM Surya Ghar सब्सिडी का पूरा लाभ
- त्वरित ROI: 3 से 4 साल में निवेश वापस
- बैटरी बदलने या रखरखाव का कोई खर्च नहीं
2. Off-Grid (बैटरी बैकअप)
Operates 100% independent of the electrical grid. Essential for remote farmhouses, agricultural sites, and zero-grid regions.
- 24/7 दिन एवं रात लगातार बिजली बैकअप
- सरकारी ग्रिड लाइन न होने पर भी संचालित
- संपूर्ण ऊर्जा स्वतंत्रता
- उच्च प्रारंभिक लागत (बड़ा बैटरी बैंक)
3. Hybrid (हाइब्रिड)
The ultimate flexibility: offsets heavy power consumption with net metering while keeping critical home or hospital loads alive during outages.
- नेट मीटरिंग + ब्लैकआउट पावर बैकअप
- सोलर से लोड चलाकर अतिरिक्त ऊर्जा बैटरी में स्टोर
- हॉस्पिटल, क्लिनिक एवं प्रीमियम घरों हेतु आदर्श
- सर्वोत्तम ऊर्जा सुरक्षा

Frequently Asked Questions
In Chhattisgarh, residential consumers receive a combined subsidy of ₹1,08,000 (₹78,000 Central grant + ₹30,000 State grant) on 3 kW and 5 kW systems. This brings down the effective cost of a 3 kW system to approx ₹1,02,000, and a 5 kW system to approx ₹2,02,000.
No. For electrical lineman safety (Anti-Islanding protection mandated by CEA/DISCOM), on-grid inverters shut down when the main utility grid fails. If you require continuous power during blackouts, a Hybrid or Off-Grid architecture is recommended.
With the government subsidy in Chhattisgarh, a 3 kW system achieves full capital payback in ~3.8 years, while a 5 kW system pays back in ~3.7 years. Over their 25-year warranted lifecycle, homeowners save between ₹9.06 Lakh and ₹16.12 Lakh.
Approximately 100 sq.ft of shadow-free rooftop space is required per kilowatt of solar panel capacity. A 3 kW installation needs ~300 sq.ft, while a 5 kW setup requires ~500 sq.ft.
