What Jacksonville homeowners should check

Jacksonville systems must account for hurricane winds, heavy rain, humidity, salt exposure near the coast, and widespread tree cover. Wind-rated attachments and a careful roof-life review are important before installation.

JEA and FPL serve different parts of the region and use separate solar programs. Confirm the utility from the service address before relying on an export-credit or interconnection assumption.

At the state level, Florida currently uses full retail net metering. A typical interconnection takes 3–8 weeks, but utility review and local permitting can extend that range. Check current rules before relying on a proposal's export-credit or installation-date assumptions.

What should I verify before signing a solar contract in Jacksonville?

Confirm that the quote names your actual utility, uses a recent electricity rate, includes measured shade and roof-condition findings, and explains who handles permits and interconnection. Ask the installer to separate guaranteed equipment and workmanship terms from estimated production, incentives, and savings.

Illustrative 5.3 peak sun hours, 14.08% production losses, 12.0 cents/kWh and $2.8/W. The retail-value ceiling assumes every kWh earns retail value; lower export credits reduce it. The cost/value ratio is not a full payback model and excludes repairs, financing and rate changes. No new Section 25D homeowner credit in 2026.
