Solar + Battery ROI Calculator in Texas
See exactly how adding battery storage impacts your savings.
Most Solar Owners Never Rerun the Math
When you installed solar, your savings were based on:
Specific buyback rates
Utility plan structure
Projected retail rates
But if:
Export credits dropped
You switched providers
Retail rates increased
Your original projections may no longer be accurate.
Battery ROI depends on your current plan — not the one you signed up under years ago.
What This Solar + Battery Calculator Analyzes
Our Texas-focused calculator evaluates:
Your daytime solar production
Your nighttime consumption
Current export credit rates
Retail electricity rates
Peak usage patterns
Backup goals
It then estimates:
Potential reduction in grid purchases
Reduced exposure to low buyback credits
Peak rate avoidance
Estimated payback timeline
This is not a generic national calculator.
It is built around Texas rate structures and real homeowner usage patterns.
The Key Factors That Change ROI
1. Buyback Rate Difference
If you are exporting at:
3¢ per kWh
But buying back at
14–18¢ per kWh
The spread significantly impacts long-term savings.
2. Evening Usage
Homes with high post-sunset consumption often see stronger ROI from storage.
Air conditioning, cooking, entertainment, and EV charging increase battery value.
3. System Size
Larger solar systems with excess daytime production typically benefit more from storage.
4. Rate Volatility
Texas electricity pricing changes more frequently than many homeowners realize.
Battery storage reduces exposure to those fluctuations.
What You’ll See in Your Custom Battery Analysis
Your custom report includes:
Estimated battery sizing
Projected reduction in exported energy
Estimated decrease in grid imports
Backup configuration options
Federal tax credit impact
Approximate payback timeline
Every home is different.
The calculator provides a starting point.
A full system evaluation refines the numbers.
ROI Isn’t Just Financial
Battery storage also provides:
Outage protection
Stability during grid failures
Reduced dependence on utility policy changes
Greater long-term predictability
Some homeowners pursue storage purely for financial optimization.
Others value resilience just as much.
True ROI includes both cost and control.
Is the Solar Battery ROI Calculator Accurate?
Online tools use estimates.
The most accurate projections come from:
Reviewing your last 12 months of utility bills
Analyzing solar production data
Evaluating your load profile
Confirming inverter compatibility
The calculator gives a high-level projection.
