How Much Will You Save Every Month?
Let us take a real example. A typical Indian household in Chennai with a monthly electricity bill of ₹4,000 installs a 5 kW solar system:
- Monthly savings on electricity: ₹3,500 – ₹4,000
- Annual savings: ₹42,000 – ₹48,000
- System cost after subsidy: approx ₹2,00,000
- Payback period: 4 to 5 years
- After payback: Free electricity for 20+ years
The solar panels come with a 25-year performance warranty. That means after your payback period of 4 to 5 years, you generate free power for the next 20 years — saving lakhs of rupees over your lifetime.

On-Grid vs Off-Grid vs Hybrid — Which is Right for You?
On-Grid System (Most Popular)
- Connected to the electricity grid
- Excess power exported to grid via net metering — you earn credits
- No batteries needed — lowest cost
- Best for: Urban homes with reliable grid supply
Off-Grid System
- Completely independent from grid
- Requires batteries for night use
- Higher cost due to battery bank
- Best for: Rural areas, farmhouses, places with frequent power cuts
Hybrid System
- Connected to grid AND has battery backup
- Best of both worlds
- Higher upfront cost but maximum benefits
- Best for: Areas with frequent outages who also want net metering benefits
For most Indian urban and semi-urban homeowners, an on-grid system is the smartest and most affordable choice.
