Commercial solar panel systems are individually designed, custom-made, grid-tied solar power systems for commercial buildings. Systems Integration designs, installs, maintains, and monitors commercial solar power systems, and we work with customers to calculate your return on investment, apply for relevant rebates, secure solar system financing, and manage your installation project from start to finish including permits and inspections.

Texas companies turn to us for commercial solar panels in order to lower operating costs, reduce tax liability through government credits and accelerated depreciation, and grow revenues by differentiating from competitors.


Systems Integration is more than a commercial solar panel installer. We offer full end-to-end solar solutions and complete project management from start to finish. Our services include free site analysis, engineering and design services, financing, rebate application, installation, permitting, inspections, monitoring, and ongoing service and maintenance.


We work to maximize your investment in commercial solar panels and exceed your expectations. That begins with your custom proposal and in-person site survey. We provide a detailed analysis of your system layout, cost and savings benefit including applicable tax credits and rebates, performance estimate, energy offset, preferred solar panel and other equipment, timeline to completion, and financing options.


For Systems Integration, no two commercial solar installation projects are alike. Each system is specifically designed to meet your needs, and the limitations of your building’s structure and budget. We will design each system to comply zoning restrictions, mounting and location limits, and to make it as aesthetically pleasing as possible.


Systems Integration provides various options to work within your budget. With the solar tax credit, 30% of all solar energy system installation costs are subtracted directly from your federal income tax payments! Financing options include cash purchase, operating lease, capital lease, and Power Purchase Agreement (PPA).


Let us handle the paperwork. Systems Integration takes care of all permitting associated with your new solar panel installation, including all utility interconnection agreements, net-metering applications, local building and electrical permits, and all rebate incentive documents.


You only want the best for your commercial solar installation. Let us handle every detail of your solar panel installation. We install solar panels as well as solar batteries and generators across the state of Texas.


Complete customer service means that we are fully invested for the life of your commercial solar panel system. Systems Integration monitors performance to ensure that your panels achieve optimal output every day. If we detect an issue, we address it. In addition, your new system includes a web-based application so that you can monitor your savings in real time, anytime.

Most commercial grade solar panels have at least 96 solar photovoltaic cells per panel, as compared to 60 or 72 cells for residential solar panels. Commercial and industrial solar applications tend to favor a white backsheet and silver frame, both of which slightly increase efficiency (by about 1% to 2%).

Commercial solar power systems typically use three-phase inverters, which provide more power than single-phase inverters. A three-phase inverter offers more voltage in a smaller size, and it is also less expensive.


Commercial solar panels are usually installed on the facility’s rooftop, with different applications for flat and pitched roofs. The systems can also be installed on multi-vehicle solar carports or elsewhere on the grounds of the property. Our approach is to find the most cost effective way to attach solar to your specific application.

  • Ballasted commercial solar systems do not require penetration of the roof and are appropriate for flat roofs including TPO. There are two types of ballasted systems: east-west and south-facing. East-west systems resemble a wave that stretches across the roof, where the panels are connected end-to-end. These types of systems provide less output per panel but allow you to put more panels on a roof, resulting in higher overall annual solar power production. South facing systems provide more power per panel at a specific time of day, which can provide a better near term ROI. However, spacing is required between each row of panels for shade mitigation, which up to 25% of the roof cannot be covered with panels. On some flat roofs, the solar PV system can be attached using a torchdown method, but that tends to be more costly than ballasts.
  • Attached commercial solar panel systems are used for pitched roofs. Panels are attached with flashing to prevent water leaks on comp shingle roof types or with clamps on standing seam metal and R Panel roof types. Roof penetration is required for comp shingle and R Panel roof types, but not for standing seam metal.
  • Solar carports may be installed over surface parking or on top of parking structures (i.e. the top floor of a parking garage). Solar carports provide shade for vehicles along with solar power. In most cases the panels are still wired to the main facility’s meter.
  • Ground mount commercial panel systems may be installed when sufficient roof space isn’t available. These systems are typically less expensive than carports because fewer materials are required for the array infrastructure, but depending on their location on the property additional trenching may be required.


The principles behind commercial solar power systems are similar to residential systems but on a larger scale and typically with better financial returns. Solar panels are typically installed on the rooftop, either ballasted or mounted depending on the roof type, on the ground, or on a shade structure in a parking lot or parking garage.

Systems are low maintenance with lifetime warranties, depending on the solar panel and inverter manufacturer. Systems Integration provides a workmanship warranty for all of our commercial solar energy systems.

Once installed, your grid-tied solar power system will generate power that is converted to alternating current at the inverter and then fed into your service panel, where it will power your facility. The grid will still provide the additional power required to meet your load, and any power produced by your solar system that exceeds your usage will be returned to the grid. Utilities offer net metering to credit your account for the excess power you generate.


Commercial solar panels are a smart investment to lower your tax liability, reduce your operating expenses, and further your sustainability goals and marketing efforts. For many businesses, solar is primarily a financial decision. The cost of solar installation is partially offset by federal and local incentives including tax credits, depreciation, grants such as the Rural Energy for America Program (REAP) managed by the USDA, and rebates. An investment in commercial solar power provides a strong internal rate of return (IRR) and a more favorable payback period than most residential systems.

Growing numbers of businesses in the United States are seeing the financial and environmental benefits of solar energy, leading to a record 3.5 gigawatts of projects under contract as of August 2018. Companies such as Walmart, Kohl’s, and Amazon are leading the way, with growth across many corporate sectors.

Partner with the number one solar contractor in Texas for a hassle-free commercial solar power system installation. We offer attractive financing options, including new in-house financing, that combine with tax credits, depreciation, and local rebates to maximize your return on investment and shorten your payback period.


You must own the building or property and have a large unobstructed area on the roof or grounds. For rooftop solar, your roof should be in good condition. The financial payback for solar is especially compelling if you have higher electrical loads during the day and/or the summer and a passthrough ownership structure with significant tax liability.

Solar may not make as much financial sense for companies with shaded facilities, a roof or electrical service that requires repair or upgrade, or who do not have the capital to invest in a system upfront. Financing options are available but typically require a down payment of at least 30 percent.
