This solar size estimator is for informational purposes only, providing rough estimates based on simplified assumptions, historical NREL PVWatts data, average local rates, seasonal usage patterns, and approximate costs. Actual savings, system size, and payback can vary widely due to individual factors like consumption, roof conditions, shading, incentives, and utility policies; no net metering is assumed, and results are not guaranteed or financial advice.

Solar produces energy for DFW Homes

Sunlight reaches the panels. DFW gets strong solar irradiance, especially in summer, making it ideal for rooftop solar.

Did you know?

The DFW Area receives about 5.3–5.7 peak sun hours per day on average—among the highest in Texas.

Specific insight:

Summer months can deliver 20–30% more solar production than winter due to longer days and higher sun angles.

Converts DC electricity from the panels into AC power for your home and the grid. (Note: Diagram shows a string inverter. Microinverters—one per panel—may be an alternative in cases of shading or varied roof orientations.)

Did you know?

Inverters are the "brain" of a solar system.

Specific insight:

String inverters are cost-effective for unshaded roofs, but microinverters can increase total production by 5–25% in partially shaded DFW homes (trees, chimneys, etc.).

Distributes AC power throughout your home and connects to the utility meter and grid.

Did you know?

A typical home solar system adds a dedicated breaker in your main panel, often requiring a 200-amp panel upgrade if yours is older.

Specific insight:

In Texas, many homes have 200-amp service, but older Fort Worth properties may need a panel upgrade or subpanel to safely handle solar backfeed.

Stores excess solar energy for use at night, during outages, or peak times. Very useful in Texas weather.

Did you know?

Battery capacity is measured in kWh—most homes install 10–15 kWh to cover evening usage or short outages.

Specific insight:

With frequent Texas storms and occasional grid instability, batteries can provide whole-home backup for hours (or days with conservative use) when paired with solar.

Measures electricity you use from the grid and excess solar you send back (net metering credits vary by provider, e.g., Oncor, TXU).

Did you know?

Texas is one of the few states without statewide net metering rules—credits depend entirely on your retail electricity provider.

Specific insight:

Many DFW providers offer 1:1 net metering (full retail credit for excess solar), but some cap credits or pay lower wholesale rates—check your specific plan before installing.

Utility network (e.g., Oncor in DFW). You get credits for excess solar production and draw power when your system isn't enough.

Did you know?

Oncor delivers power to over 10 million Texans but doesn’t sell electricity—your retail provider (TXU, Reliant, etc.) handles billing and solar credits.

Specific insight:

In deregulated DFW, switching providers can optimize solar savings—some offer solar-specific plans with better export rates or time-of-use billing alignment.
