Commercial solar financing in Tampa: how businesses model the deal

Commercial solar is a different analysis from residential, and the financing follows the load profile.

Start with the demand charge

Many commercial TECO and Duke accounts carry demand charges based on peak kilowatt draw, not just consumption. Solar reduces consumption reliably; it reduces peak demand only partially unless storage is involved. Model both lines separately or the projection is wrong.

Roof membrane governs mounting

On flat roofs, ballasted racking avoids penetrations but adds weight; attached racking penetrates but weighs less. The membrane manufacturer's requirements often decide, because violating them voids the roof warranty. See flat roof commercial solar.

Structural capacity

Older Tampa warehouse and retail structures need a structural review before ballast is considered. That is an engineer's determination.

Financing structures

Commercial deals may use equipment finance agreements, capital or operating leases, or PPAs with a third-party owner. Which is best depends on your balance sheet treatment and tax position — a question for your CPA, not your solar salesperson.

Timeline

Commercial permitting and interconnection run longer than residential. Build that into any budget cycle assumption.
