Hillsborough County by the numbers
Source: Hillsborough County permit records (2025-10-27 to 2026-10-27). Values are what was declared on the permit application, not a price quote or final invoice; ask several licensed contractors for quotes. How we counted
What the permit data can tell you
Hillsborough County permit records show 1,348 solar permits and 97 contractors represented during the reporting period. That describes recorded activity, not installation prices or completed projects.
Declared permit values are not price quotes. With no usable valuation figures in the supplied data, there is no supported basis here for a typical project cost.
Compare equipment and installation scope
Ask each contractor to identify the panels, inverter equipment, mounting system and monitoring included in the proposal. Request a written explanation of how the design fits your roof and electricity use.
Have the contractor identify electrical upgrades, roof repairs and other work separately. A proposal that excludes needed work may be difficult to compare with one that includes it.
Separate solar generation from backup
Request a solar proposal with battery storage identified separately if backup power interests you. Ask what equipment and electrical work the backup design includes and which household loads it is intended to support.
Have the contractor explain operation during a utility outage. Do not assume that a proposal for panels includes a functioning backup system.
Compare payment terms and written protections
If financing is offered, compare the cash purchase terms with the financing agreement. Ask about the total repayment obligation, payment changes and any conditions attached to advertised savings.
Read manufacturer warranties and contractor workmanship terms separately. Ask who handles equipment claims, roof leaks, service visits and panel removal if roof work becomes necessary.
Get proposals from independent contractors
Give contractors the same information about your electricity use, roof plans and backup goals. Ask them to identify exclusions and explain differences between their designs before choosing.

Questions homeowners ask
What is the average solar installation cost locally?
The supplied Hillsborough County permit records contain no usable valuation figures to support an average or median cost. Cost varies; get several quotes based on your roof, electrical equipment and chosen system.
Is a declared permit value the installation price?
Declared permit values are not price quotes. Do not use them as a substitute for a contractor's written proposal detailing equipment, labor, exclusions and payment terms.
How can I compare different solar proposals?
Compare equipment models, proposed layout, production assumptions, roof and electrical work, battery scope, exclusions and payment terms. Ask each contractor to explain differences in writing.
Does RG Holdings provide a solar warranty?
No. RG Holdings operates the referral service. Review any equipment warranty with the manufacturer and any workmanship warranty with the contractor you choose.
