Floating solar (floatovoltaic or FPV) design software handles PV systems mounted on floating platforms over reservoirs, lakes, and irrigation ponds. The water-cooling effect boosts yield, and the geometry has unique considerations. This guide covers the 2026 options and explains how SurgePV ships floating solar inside its solar design software on every paid plan.

Who Should Choose Each Tool
- Choose SurgePV for floating solar plus the rest of the workflow at flat per-seat cost.
- Choose PVsyst for lender-mandated bankable reports on first-of-its-kind FPV projects.
- Choose specialist marine engineering tools for the anchoring side, which SurgePV does not handle.

Frequently Asked Questions
What is floating solar design software?
Floating solar (floatovoltaics or FPV) design software handles the layout, shading, and yield for PV systems mounted on floating platforms over water (reservoirs, lakes, irrigation ponds). The water cooling typically boosts yield 5 to 10 percent, and the geometry has unique considerations. SurgePV supports floating solar templates on every paid plan.
Does SurgePV include floating solar templates?
Yes. SurgePV ships floating solar (FPV), carport, ground-mount, BIPV, and agrivoltaic templates alongside standard rooftop workflow. The FPV template handles platform geometry, anchoring assumptions, and water-cooling yield adjustments.
How does water cooling affect floating solar yield?
Modules over water typically run 3 to 8 degrees cooler than land-mounted modules in the same climate, which improves efficiency. Bankable simulators including SurgePV apply a temperature coefficient adjustment that captures this effect in P50, P75, P90 yield outputs.
Is floating solar bankable for project finance?
Yes when properly designed. The 8,760-hour module-level methodology applies. SurgePV produces bankable yield outputs for FPV projects. PVsyst remains the lender-mandated tool on some first-of-its-kind floating projects.
What is the typical project size for floating solar?
Floating solar projects range from small irrigation ponds at 100 kW to large hydropower-paired installations at 500+ MW. SurgePV handles the full range with terrain and water-area import, plus 8,760-hour module-level shading.
Does floating solar design software handle anchoring?
Software handles the electrical and yield design. Anchoring engineering for the floating platform itself happens in a separate marine engineering workflow. SurgePV exports drawings that the anchoring engineer uses as the basis for the platform design.
What does floating solar design software cost?
SurgePV's FPV workflow is included on every paid plan at $1,299 to $1,899 per user per year. There are no specialised FPV-only design tools at the same price point. PVcase and RatedPower can be configured for FPV at enterprise pricing.
Do I need dedicated floating PV design software?
Not a separate license, but you do need three capabilities most rooftop tools lack: platform geometry on a float grid rather than a roof plane, the water-cooling effect on module temperature (typically a 5 to 10 percent yield uplift that a standard thermal model will miss), and anchoring layout against water level variation. SurgePV covers all three inside the standard license, so floating solar does not require a second purchase.
