Solar PPA for marinas

Pontoon + clubhouse + boat-charging load on daytime.

Typical system size	50–250kWp
Year-1 tariff	13–17 p/kWh
Best-fit structure	On-site PPA (sleeved for multi-site groups)

A waterside load that peaks in the sunshine

Marinas draw power in exactly the pattern solar likes. Shore-power pedestals feed berthed vessels, the boat hoist and travel-lift run through the working day, the boatyard workshop hums, and the clubhouse, chandlery and restaurant serve a summer crowd. All of it concentrates in the daylight, warm-season months when a rooftop is at its most productive — and as electric and hybrid boats grow more common, daytime charging demand at the pontoons is climbing fast.

Modest systems, premium value

Marina arrays are among the smaller ones we see, typically 50 to 250kWp, sited on boat sheds, dry-stack buildings and clubhouse roofs. Tariffs correspondingly sit at the upper end, around 13–17 p/kWh — still a genuine saving on grid import for a coastal site where standing charges and network costs often bite hard. Because your busiest, sunniest months line up with the highest berth occupancy, self-consumption stays strong through the season.

Charging the electric-boat future

Pairing panels with battery storage lets a marina buffer daytime generation and release it into evening pedestal and vehicle charging, smoothing the peaks that would otherwise mean expensive grid draw. It is a practical way to offer green berthing and EV points without simply passing a rising energy bill to your members.

Worth checking at survey

• Salt-air corrosion rating of the mounting and inverter hardware — coastal specification matters.
• How shore-power metering is arranged, and whether pedestal load is separately billed to berth holders.
• Roof access and wind loading on exposed waterfront structures.
