Energy storage solutions aren’t one-size-fits-all. A small ranch-style home in Mesquite has different needs than a 5,000 sq ft estate in Westlake or a small restaurant in Deep Ellum. This guide walks through the most common DFW energy storage applications, how we approach sizing, and the brands and technologies we install.
Residential vs Commercial Storage
Residential energy storage solutions are typically smaller (10-50 kWh), focused on backup power and self-consumption, and integrated with rooftop solar.
Commercial storage solutions are larger (50-500+ kWh for small business applications), more focused on demand charge reduction and rate optimization, and sometimes designed for utility grid services participation.
The technology underneath is similar — lithium iron phosphate (LiFePO4) batteries with appropriate inverters and controllers. The application logic, sizing methodology, and economic case are different.
We design both. Our approach is the same: understand the property’s actual load profile, identify the specific goals (backup, savings, both), then engineer a system sized appropriately.
Use Cases We See Most in DFW
The most common residential energy storage applications in our market:
Solar self-consumption + outage backup. The most common configuration. Homeowner has solar (existing or new), adds battery storage for nighttime self-use and grid outage protection. Typical sizing: 12-25 kWh.
Standalone backup for HOA-restricted homes. Many DFW neighborhoods have HOAs that ban or restrict generators. Battery storage is often the only viable backup option. Typical sizing: 10-20 kWh for essential loads.
Whole-home backup with AC. Affluent homes prioritizing summer outage comfort. Includes air conditioning in backup. Typical sizing: 30-45 kWh.
Energy independence pursuit. Homeowners targeting maximum grid independence. Solar + battery sized for multi-day autonomy. Typical sizing: 30-60 kWh with substantial solar.
Common small commercial applications:
Restaurant or retail backup. Continuous operation during outages. Refrigeration, point-of-sale, lighting. Typical sizing: 30-100 kWh.
Medical practice backup. Specific equipment continuity, patient safety. Typical sizing: 30-80 kWh.
Small office backup. Operations continuity, communications. Typical sizing: 20-50 kWh.
Demand charge reduction. Commercial property reducing peak demand on time-of-use plans. Typical sizing: 50-150 kWh depending on load profile.
Sizing Methodology
Our approach to sizing isn’t templated — it’s engineered for each property.
What we evaluate:
Load analysis. What does this property actually consume? When? Peak draws vs continuous loads?
Backup priorities. What MUST stay running during an outage? What’s nice-to-have? What can be sacrificed?
Solar capacity (if present or planned). Solar generation profile determines how the battery recharges during extended outages.
Outage profile expectations. Are we sizing for 6-hour summer outages, multi-day ice storm events, or something in between?
Budget constraints. Realistic budget shapes which goals can be fully met vs. partially met.
Future expansion. EVs, additions, business growth — all factor into present sizing decisions.
The output is a specific system design: battery capacity, inverter rating, control architecture, electrical integration. Not “you need 20 kWh” — but the actual engineered system that will deliver the outcomes you’re after.
Brands & Equipment
The energy storage solutions we install in 2026:
FranklinWH aPower 2 — Primary recommendation for many residential applications. 15 kWh modules, stackable, excellent load management via aGate controller. LiFePO4 chemistry.
Tesla Powerwall 3 — Strong residential option, integrated solar inverter for new installs.
Enphase IQ Battery — Modular sizing, best pairing with Enphase microinverter solar.
Other Tier-1 brands for specific applications where their architecture is the best fit.
For commercial applications, we install larger-format systems with appropriate inverter and control infrastructure. Specific brands depend on application requirements.
Permitting & Install Timeline
DFW permitting for battery storage:
- Building permit and electrical permit from your city
- Utility interconnection paperwork with your TDU
- Typical permit timeline: 2-4 weeks
- HOA notification (typically less involved than solar)
Physical installation:
- Single-day install for smaller residential systems
- 2-3 days for larger or more complex installations
- Commercial installations vary by size and complexity
End-to-end timeline (signed contract to operational):
- Residential: 4-8 weeks typical
- Small commercial: 6-12 weeks typical
Financing Options
Energy storage installations qualify for multiple financing approaches:
30% Federal Investment Tax Credit. Applies to both solar-paired and standalone battery storage. Significant cost reduction.
Solar loans. If installing solar + battery together, single financing covers both. Various lenders specialize in solar/storage financing.
Cash purchase. Best long-term economics for owners with available capital.
HELOC or home equity. Often lower rates than solar-specific loans for residential applications.
Manufacturer financing. Tesla, FranklinWH, and others offer financing programs.
Commercial financing. PACE financing, equipment loans, and operating lease structures all available for commercial energy storage projects.
The right financing depends on tax situation, available capital, and project specifics. We help homeowners and business owners think through the options, though we recommend consulting a CPA or financial advisor for specific tax planning.
Why Custom Design Matters
The biggest mistake we see in the energy storage market: off-the-shelf system packages applied to homes and businesses that don’t fit the package’s assumptions.
A “10 kWh starter system” works fine for the right home. For a home with different load patterns, it might be undersized for the intended backup goals. For another home, it might be oversized vs. actual needs.
The same applies to commercial. A 50 kWh package works for some small businesses. For others, the sizing is wrong by a factor of two or three.
Real engineering — understanding the specific property and designing for it — is the difference between a system that delivers and a system that disappoints.
Getting Started
If you’re considering energy storage solutions for your DFW home or business, the smartest first step is a real consultation. We’ll evaluate your loads, your goals, your existing infrastructure, and recommend an engineered system sized appropriately.
We install across the DFW metroplex for both residential and small commercial applications. Reach out for an honest conversation about what’s possible and what it would cost.
