FLORIDA COMMERCIAL SOLAR · GUIDEFPL Commercial Solar Interconnection & ROI Guide
FPL screening starts with the service account and the current regional interconnection agreement. Use the official utility documents for the applicable tier and confirm requirements before installation.
Key screening facts
FPL lists AC tiers of up to 10 kW, above 10 through 100 kW, and above 100 through 2,000 kW. Its guideline uses 0.85 × array DC kW for GPR; confirm the agreement calculation. It sets a production screen below 115% of annual consumption and a 90% service-capacity screen, with potential customer-paid upgrades. Systems of 50 kW or more require listed three-phase wye service. Tier 2/3 disconnect requirements, prohibited meter-can/utility-transformer connections and battery export restrictions must be checked against the current guideline.
What those screens mean for a business
Gather annual kWh, account classification and service information before selecting final capacity. Roof capacity and utility capacity are different constraints. A service upgrade is a project cost and schedule input, not an automatic entitlement. Ask the design team to document the basis used for each screen.
Demand charges and export economics
Model energy offsets separately from billed demand. Cloud cover and demand measurement windows can change peak outcomes. Do not use an annual average solar output to promise a demand-charge reduction. Obtain the account tariff for export banking, year-end settlement and fixed charges; no fixed avoided-cost rate is built into the calculator.
Application and engineering handoff
Use the current tier agreement for fees, insurance, studies and submission steps. Do not promise a ten-day approval or apply Northwest terms to another territory without checking. A three-phase screening estimate V × I × √3 / 1000 × 0.90 expresses a kVA screen; it does not establish approved real-power capacity. Have the engineer reconcile power factor and utility definitions. NEC 690 and 705 provisions must match the code edition adopted by the authority having jurisdiction; section numbering is not an installation instruction.
What could solar change for your business?
Explore a free cash-ownership scenario. Send a bill for a preliminary financial review — the estimate itself is ungated.
Utility and roof selections help route your review. Rates and roof suitability are not inferred from these selections.
View and edit scenario assumptions
Demonstration assumptions: 12 W per usable sq ft; 1.5% annual maintenance; 0.5% annual degradation; 2% annual energy/maintenance escalation. No applied credit, depreciation, demand reduction, replacement cost or export revenue. A reviewed report must include project-specific replacements and tax timing.

Model assumptions & honest limits
- Illustrative cash-ownership model; not a tariff simulation or engineering proposal.
- All cost, yield and escalation defaults are demonstration assumptions, not sourced market quotes.
- Fixed charges, financing, property-tax savings and storage are excluded.
- Net operating savings are reduced by the entered effective tax rate; tax capacity and deductibility require review.
- Annual usage inferred from assumed energy-only share of spend; replace with bills.
- Export value is zero until applicable utility terms are confirmed.
- Tax benefits are zero until a project-specific schedule is confirmed.
Tax benefits start at zero pending project review. This estimate is not a quote, tariff simulation or guaranteed return.
