Overview
This small commercial solar and battery installation was designed to reduce energy costs and improve resiliency for a 5,000 square foot flex industrial facility in Grapevine, Texas.
The building owner sought a practical solution that would offset daytime electric consumption while also providing backup power during grid outages. In addition, the project needed to leverage available utility incentives and Federal tax credits to ensure strong financial return.
Holistic Utility Solutions was engaged to provide turnkey delivery from design through installation.
Progress
Holistic developed and implemented a small commercial solar and battery installation consisting of:
- 11 kW roof-mounted solar photovoltaic (PV) system with Sol-Ark inverter
- 19.2 kWh HomeGrid battery energy storage system
- Corrugated metal roof mounting using S-5! clamps
- Generator-ready configuration for future expansion
Because the building has a metal roof, special attention was given to structural attachment. The S-5! clamp system allowed secure mounting without roof penetrations, preserving roof integrity and warranty.
The system was engineered so the entire facility can be backed up for approximately 4–8 hours, depending on load conditions.
Holistic managed all aspects of the project, including:
- System design and engineering
- Equipment procurement
- Installation oversight
- Utility interconnection coordination
- Incentive application and processing
The project was completed on time and within budget.
Solution
This small commercial solar and battery installation was intentionally right-sized. Solar production was matched to the building’s daytime load profile. Meanwhile, battery storage capacity was calibrated to provide meaningful outage protection without oversizing the system.
Holistic secured approximately 25% in eligible utility incentives from Oncor, totaling roughly $5,000. These incentives were passed directly to the customer.
The project also qualified for the 40% Federal Investment Tax Credit, significantly improving overall project economics.
By combining solar generation with battery storage, the facility reduced grid dependency while improving operational resilience.
Result
After application of all incentives, the solar portion of the project is projected to achieve approximately a 5-year payback.
In addition, the facility now benefits from:
- Reduced ongoing energy expenses
- Whole-building backup capability for 4–8 hours
- Increased protection against grid outages
- Improved long-term asset value
- Enhanced sustainability profile
This small commercial solar and battery installation demonstrates how flex and light industrial facilities can implement solar and storage in a financially responsible manner while strengthening operational reliability.
