Industrial Solar Installation Capabilities
Industrial-Grade Solar Project Execution
FSG delivers solar installations designed for industrial environments where safety, uptime, and coordination are critical. Our teams are experienced working within active facilities, maintaining operational continuity while meeting strict site, safety, and compliance requirements. Each project is executed with disciplined planning, clear communication, and field-level accountability.
Scalable Solutions for Complex Facilities
FSG supports rooftop and ground-mounted solar installations across manufacturing plants, warehouses, and distribution centers. We coordinate closely with facility teams, engineers, and utility providers to ensure proper integration with existing infrastructure. Our national footprint and standardized project controls allow us to deliver consistent results across single sites or multi-location portfolios.
Engineering
Engineered, Permitted & Code-Compliant Solar Installations
FSG provides in-house engineering support to ensure solar projects are designed for performance, compliance, and long-term reliability.
Our engineering teams evaluate site conditions, system requirements, and regulatory considerations early in the process to reduce risk and support efficient project execution.
By coordinating closely with project managers, installers, utilities, and local authorities, FSG delivers engineered solutions that integrate seamlessly with existing facilities.
This collaborative approach helps streamline approvals, maintain safety and code compliance, and support predictable outcomes from design through commissioning.
Financing Options
Commercial Solar Financing & ROI Planning
Several financing options are available for commercial solar projects:
- Power Purchase Agreements (PPA): You agree to purchase the electricity generated by a solar system installed on your property at a set price, which is usually lower than the utility rate.
- Roof lease: You lease your roof space to a solar provider who installs and maintains the solar system, and you benefit from the energy produced at a lower cost.
- Equipment loans: Similar to traditional loans, where you borrow money to purchase and own the solar system outright.
- Commercial Property Assessed Clean Energy (CPACE): Financing that allows property owners to finance the upfront cost of energy improvements and pay the costs back over time through a voluntary assessment on their property tax bill.
Tax Credits & Incentives
The federal Investment Tax Credit (ITC) covers 30% of eligible costs for most commercial solar systems. Systems 1 MW or larger must meet prevailing wage and apprenticeship requirements to qualify for the full 30%; otherwise the base rate is 6%.
Financial Modeling
Our interactive scenario models forecast solar investment costs, available tax credits, incentive stacking, and ROI projections based on your facility's energy profile, utility rates, and financing structure.

Most businesses evaluate commercial solar the wrong way. They look at the installed cost, run a simple payback calculation, and conclude the timeline is too long. That analysis is incomplete because it ignores the incentive stack that dramatically changes the real economics of the investment.
