Solar vs Electricity Bills: Real Savings Calculation for Homes & Businesses

Understanding How Solar Energy Reduces Long-Term Electricity Expenses

Electricity costs in cities like Mumbai continue to rise every year. For homeowners, housing societies, and businesses, electricity bills are often one of the largest recurring expenses.

This is why many people are switching to rooftop solar — not only for sustainability but also for long-term financial savings.

But how much can solar actually save compared to regular electricity bills?

In this guide, we break down real savings calculations and explain how solar energy changes the way you pay for power.

Traditional Electricity vs Solar Power

Electricity Bills (Grid Power)

When you rely completely on grid electricity:

• Monthly bills fluctuate
  
  
• Tariffs increase over time
  
  
• No control over pricing
  
  
• Long-term costs continue rising
  
  

Solar Power

With rooftop solar installation:

• You generate your own electricity
  
  
• Reduce grid dependence
  
  
• Stabilize energy costs
  
  
• Save over long-term system life
  
  

Example Savings Calculation

Let’s consider a typical Mumbai household:

• Monthly electricity bill: ₹8,000–₹10,000
  
  
• Annual cost: ₹96,000–₹1,20,000
  
  

Installing a properly sized solar system can:

✔ Offset 70–80% electricity usage
✔ Reduce monthly bills significantly
✔ Deliver payback within a few years

Over 20–25 years, total savings can be substantial compared to continuous grid payments.

Key Factors Affecting Solar Savings
