The 32 kW pole mount solar installation in Florida that OneWorld Solar built for the Tampa Electric Manatee Viewing Center is small, public and sited somewhere that made both of the usual mounting choices awkward. It is a useful example of the third option, and of what changes when the customer's own visitors are standing next to the array.
A visitor center is not a warehouse. The array is part of what the public sees, so appearance, sightlines and safety around it are design inputs rather than afterthoughts, and the site itself sits on a protected stretch of the Tampa Bay shoreline where the environment sets the terms.
Why a pole top array here
Roof mounts need suitable roof. Ground mounts need open, disturbable land. When neither is available, the pole top array is what remains: the modules go up on a small number of foundations, and the ground underneath stays as it was.
That property is exactly what a sensitive coastal site rewards. On a protected shoreline the constraints that govern are ground disturbance, access routes, vegetation, stormwater and timing around protected species. Those are set by permits, not by the construction schedule. A mounting method whose entire footprint is a handful of piers gives the permitting case far less to object to than an array covering an acre.
What we built
32 kW
Pole top photovoltaic array
At a public visitor center.
Minimal footprint
Foundations only at pier locations
Site left largely undisturbed.
Public-facing
Visible to visitors
Appearance and safety are design inputs.
The engineering focus on a pole mount is unusual. Instead of spreading wind load across dozens of roof attachments, the whole array delivers its load into one structure and one footing, so overturning and uplift at that single point govern the design. Soil conditions matter more here than on any other mounting type, because you cannot fix a bad geotechnical assumption by adding clamps.
A small array on a public site is not a savings project
At 32 kW, the fixed costs of design, permitting, interconnection and mobilization weigh more per kilowatt than they do on a megawatt job. If the goal is the lowest cost per kilowatt-hour, this is not the shape of project that delivers it. Systems like this get built for visibility, education and commitment, and they should be justified on that basis.
The results
OneWorld Solar has not published production or bill-savings figures for this installation. The scope described above is what the company confirms; anything beyond it should come from OneWorld Solar directly.
What the project demonstrates is a method: a mounting approach chosen because of the site's environmental constraints rather than because of what is cheapest per watt, delivered on a property that stays open to the public.
Related work and next steps
- Other installations of every mounting type are collected in commercial solar projects.
- For permitting, wind loading and utility context, see commercial solar installation in Florida.
- Roof, ground, canopy and pole top systems are all delivered under one commercial solar EPC contract.
- If a project has to justify itself on economics rather than visibility, start with commercial solar incentives, which move the numbers more than array size does at this scale.
