Reducing a $140 average monthly electric bill is the number one reason homeowners in Farmers Branch go solar. With long, hot summers in the Dallas area, air conditioning costs are a major budget item. A rooftop solar system lets you generate your own power, locking in lower energy costs for decades while improving your home's value.

Incentives & Tax Credits
Tax Credits & Exemptions for Homeowners
The single most significant incentive is the 30% federal Residential Clean Energy Credit, which directly reduces your tax liability. On top of that, Texas provides powerful financial benefits that make going solar even more affordable:
- 100% Property Tax Exemption: Your solar installation will add value to your home without adding a penny to your property tax bill.
- 100% Sales Tax Exemption: All solar panel and battery equipment is exempt from state sales tax.
Net Metering: Oncor (transmission)
No Statewide NEM
Optional
Understanding Solar Buyback in a Deregulated Market
Farmers Branch is in the Oncor service territory, meaning you must choose a Retail Electric Provider (REP). Texas lacks a standardized net metering law, so the credit you get for excess solar energy sent to the grid is determined by your REP's specific solar buyback plan. Some offer near-retail rates, while others offer much less. This complexity makes pairing a battery with your solar array a smart move; you simply store and use your own power, sidestepping unfavorable buyback rates entirely.
Projected Savings
Your Potential Savings with Solar Power
A moderately sized 4 kW solar panel system in Farmers Branch generates approximately 6,130 kWh per year. With average retail electric rates hovering around $0.14/kWh, that translates directly to more than $850 in bill savings in the first year alone. By storing excess daytime energy in a battery, you can avoid pulling expensive power from the grid during evenings, maximizing your savings and reducing your reliance on your electric provider.
