What Does an Off-Grid System Cost on Cayo Costa?
Cayo Costa projects generally run $30,000 to $60,000 for an 8 kW to 12 kW array paired with battery storage, reflecting boat and barge logistics. Most properties here run battery-first or fully off-grid rather than tied to standard utility service.
- Grid access
- No bridge, boat or barge only
- Most parcels rely on battery and generator backup
- Wind zone
- 150 mph+ ultimate design
- Fully exposed Gulf barrier island, Lee County
- Permitting office
- Lee County Building Department
- Coordinated with state park and conservation land boundaries
- Land status
- Mostly state park
- A small number of private parcels sit outside the park boundary
Pricing shown is typical and a starting point. Your exact quote is confirmed after a site survey and depends on roof condition, electrical service, equipment choices and local permitting.

An Island with No Bridge and No Grid
Cayo Costa is reachable only by boat, and most of the island is state park land, with a small number of privately held parcels remaining outside the park boundary. There is no causeway, no vehicle bridge and, for most parcels, no practical utility line. Every project here starts as a logistics problem before it becomes a design problem.
Because equipment, panels, batteries and crews all move by boat or barge, we consolidate deliveries and schedule installs in tight windows rather than making repeat runs across open water.
What we're building around
The Numbers That Shape a Cayo Costa System
Four facts drive nearly every design decision on this island.
- Utility service
- None or off-grid
- Most homes run on battery and generator rather than a metered connection
- Ultimate design wind speed
- 150 mph+
- Fully exposed to the Gulf on all sides, no shielding from adjacent development
- Jurisdiction
- Lee County Building Department
- Private parcels outside the state park boundary still require a standard permit
- Staging point
- Pineland or Bokeelia
- Mainland launch points where we consolidate materials before crossing
Logistics
How a Cayo Costa Install Actually Gets Done
Boat-access-only work runs on a different sequence than a mainland job.
01
Confirm the Parcel Line
We verify the property sits outside the state park boundary before scoping any work, since most of the island is protected land.
02
Stage Everything on the Mainland
Panels, racking, batteries and tools are staged together near Pineland or Bokeelia so nothing is missing once we cross.
03
Barge or Boat the Crew and Materials in One Trip
We plan the crossing around tide and weather windows and move the job in as few trips as possible to control cost.
04
Size the System to Actual Load
Without a utility bill to offset, we size the array and battery bank to well pump, refrigeration, lighting and communications load rather than a grid offset percentage.
05
Commission on Site
Battery, inverter and generator handoff are tested in person before the crew leaves, since a return trip isn't a quick fix.
Permitting and land status
What Building on Cayo Costa Requires
Lee County Permitting on Private Parcels
Privately owned lots outside the state park boundary go through standard Lee County building permit review, coordinated around park access rules.
Conservation Boundary Awareness
We confirm exact parcel lines against state park boundaries before any site work begins, since the majority of the island is protected land.
Elevated, Hardened Equipment
Given surge risk on a fully exposed barrier island, mounting sits well above grade with hardened enclosures rated for salt spray and periodic flooding.
Wind and exposure
Engineering for a Fully Exposed Gulf Barrier Island
Cayo Costa carries no shielding from adjacent development, sitting fully exposed to Gulf wind and storm surge with ultimate design speeds at 150 mph and above. Every mount, rail and fastener we use here is stainless and rated for that exposure, since there's no quick follow-up trip if hardware fails.
