We model ROI, incentives, depreciation, and cash flow projections to ensure the project meets your financial goals.
Lease / installation agreement review
Solar contracts are complex. We help to protect your interests by reviewing land leases, PPAs, and EPC contracts to bring clarity, identify hidden risks, and ensure you end up with a complete, fair contract.

What makes commercial solar unique?
Getting a commercial solar installation is not as simple as putting some panels on the roof and turning them on—it’s a significant financial investment designed to provide long-term value to your business. In order to do that, every project requires guidance from knowledgeable experts.
Here are some key factors that set commercial solar projects apart:
- Diverse Goals: Businesses and landowners use solar to achieve multiple goals, including energy savings, meeting organizational sustainability (ESG) targets, and hedging against demand charges and future changes in energy price stability.
- Complex finances: The proper financial structure is essential to a good commercial solar project. Each project involves a mix of federal and state incentives, accelerated depreciation schedules (MACRS), specialized financing options, and the potential for creating new revenue streams from selling energy credits. The ideal outcome is working with these factors to create a calculated, long-term ROI for your business.
- Precise engineering requirements: Whether you’re looking for a solar installation on a commercial rooftop or a ground-mounted system on land you own, the process of engineering the system is complex, requiring detailed site surveys and structural analysis, careful calculations, and expert knowledge of building and land-use codes.
How a solar energy consultant maximizes your benefits
The bottom line is every project is unique, and dealing with all the complexities listed above requires special guidance from a knowledgeable expert.
That’s where CommercialSolarGuy comes in. As your commercial solar energy consultant, we act as your advocate and strategist, ensuring your process is on track, from the day we first meet until the day we flip the switch on your project.
