Introduction: Why Solar Is a Smart Financial Move in Chennai

With electricity costs rising across Tamil Nadu, and Chennai averaging over 300 sunny days a year, solar power isn’t just eco-friendly — it’s financially smart. Homeowners are choosing solar not only for sustainability but for real return on investment (ROI).

At Newera Renewables, we've helped hundreds of customers unlock solar panel savings in Chennai, and we’re breaking down the actual numbers for you.

Why ROI Matters — Especially in Chennai

The ROI of solar panels in Tamil Nadu is among the best in the country, and here’s why:

High TNEB electricity tariffs and slab-based billing
Consistent solar generation potential (5.5–6.5 kWh/m²/day)
Government subsidies for residential systems up to 10kW
TNEB net metering savings let you sell excess power back to the grid

Together, these factors make solar installation in Chennai a low-risk, high-return investment.

Real Numbers: Bi-Monthly EB Savings Breakdown

Here’s a real-world look at savings based on system size and average consumption. These estimates reflect common solar panel system sizes (2kW–5kW) installed by Newera Renewables in Chennai homes.

System Size	Bi-Monthly Solar Generation (approx.)	TNEB EB Bill Before Solar	EB Bill After Solar	Bi-Monthly Savings
2 kW	~600 units	~₹3,500	~₹200	₹3,300
3 kW	~900 units	~₹6,500	~₹500	₹6,000
5 kW	~1,500 units	~₹13,500	~₹900	₹12,600

These are actual savings ranges we've seen among Newera Renewables customers, based on regular household consumption and good rooftop exposure.

Case Study: 5kW System Installed in Anna Nagar

Meet Mr. Anonymous, a homeowner from Anna Nagar who recently partnered with us for a solar upgrade.

Bi-Monthly Savings: ₹12,600 on average
Annual Savings: ₹75,600
Estimated Payback Period: 3.2 years
Projected 25-Year Savings: ~₹19,00,000

“After installing our 5kW system, we rarely worry about EB bills anymore,” says Mr. Anonymous. “Newera Renewables made the entire process smooth — from paperwork to installation. Highly recommended!”

This story isn't unique — hundreds of Chennai homeowners are experiencing similar results.

What Influences ROI?

While solar consistently delivers great returns, a few factors can slightly affect your actual ROI:

Roof Angle & Shadow-Free Area: A south-facing, unshaded roof boosts output.
Electricity Usage Patterns: Homes using more power during the day benefit more.
Type of System: Grid-tied systems have better ROI than off-grid or battery-backed ones (unless power cuts are frequent).
Maintenance – Regular cleaning ensures optimal output.
