Solar vs Electricity Bill: 5 Years Cost Comparison
Electricity bills are increasing every year. Many homeowners are now thinking:
“Should I keep paying monthly bills or invest in rooftop solar?”
In this blog, we will compare solar vs electricity bill for 5 years in a simple way so you can clearly understand which option saves more money.
Understanding the Two Options
1. Electricity from Grid
This is the normal power supply you get from your local electricity board.
- You pay every month
- Tariff increases every year
- No long-term control on cost
2. Rooftop Solar System
Solar panels are installed on your roof to generate electricity from sunlight.
- One-time investment
- Very low electricity bill
- Works for 25+ years
Average Monthly Electricity Bill in India
Let’s take a simple example:

- Yearly bill: ₹60,000
Electricity prices increase every year by around 5%–8%.
