Frequently Asked Questions

Technology & General Overview

1. What is floating solar (FPV)? Show answer

   Floating solar, or Floating Photovoltaics (FPV), is the deployment of solar PV systems on water bodies such as reservoirs, industrial ponds, treatment basins, and irrigation storage. Solar modules are mounted on buoyant platforms that are anchored or moored in place while remaining electrically and mechanically isolated from the water.

2. Why consider floating solar instead of ground-mounted solar? Show answer

   Floating solar can:

   • Preserve valuable land
   • Reduce water evaporation
   • Improve module performance through passive cooling
   • Shorten interconnection distances at water and industrial facilities
   • Reduce grading, trenching, and civil scope

   FPV is often particularly well-suited to municipal, industrial, and utility-owned water assets.

3. Where is floating solar commonly deployed in the U.S.? Show answer

   Typical applications include:

   • Drinking Water Reservoirs
   • Wastewater Treatment Plants
   • Industrial and Process Ponds
   • Irrigation Reservoirs
   • Stormwater Retention Facilities

System Design, Engineering & Standards

1. Are AccuSolar systems designed to recognized codes and standards? Show answer

   Yes. System designs are developed using applicable U.S. structural, wind, and electrical standards. Where required, third-party Professional Engineers coordinate site-specific analysis and stamping in accordance with jurisdictional requirements. AccuSolar also offers Project Readiness Evaluation Analysis (PRE) which will tackle specific project location requirements and determine overall feasibility of the project.

2. How are floating solar systems engineered? Show answer

   Floating solar systems are engineered to account for:

   • Wind Uplift and Drag
   • Wave Action and Dynamic Loading
   • Water-Level Variation
   • Long-Term Fatigue and Cyclic Motion

   AccuSolar systems use a rigid aluminum structural frame coupled with high-buoyancy floats, which provides predictable load paths and simplifies engineering review. Systems are designed to account for long-term cyclic loading and fatigue associated with wind, wave, and operational movement over the asset life.

3. How does wind loading differ for floating solar systems? Show answer

   Wind behavior over water differs from land-based conditions. Floating solar systems must address both uplift and lateral drag. AccuSolar systems incorporate tilt control and zero-degree stow capability, which significantly reduces wind exposure during extreme events.

4. How are wave forces addressed? Show answer

   Wave forces are managed through conservative spacing, buoyancy margin, and anchoring design. For exposed sites, wave attenuation systems may be incorporated. AccuSolar’s rigid framing reduces differential movement between modules compared to flexible mat-style systems. Many ideal floating solar applications experience wave heights of approximately 1 foot or less at the array, though systems can be engineered for more exposed conditions with appropriate design measures.

Anchoring & Mooring

1. How are floating solar systems anchored? Show answer

   Anchoring methods are site-specific and may include:

   • Deadweight Anchors
   • Helical Anchors
   • Shore-Based Anchors or Piles
   • Hybrid Mooring Systems

   Flexible mooring lines which remain under constant tension are used to accommodate water-level fluctuations. If below water anchors are to be used, often times a bathymetry study mapping out the water body floor are required.

2. Does AccuSolar supply anchoring systems? Show answer

   AccuSolar does not manufacture anchoring directly but coordinates anchor design, specification, and integration with qualified third-party specialists. Anchoring loads are transferred through the aluminum structural frame rather than individual plastic floats. AccuSolar’s scope of work may include coordination and supply of anchoring components, depending on project delivery structure, to simplify requirements for the EPC or developer.

3. Why do AccuSolar systems often require fewer anchors? Show answer

   Several design factors reduce anchoring demand:

   • Load transfer through a rigid aluminum frame
   • Higher buoyancy margin and float-to-panel ratio
   • Ability to stow modules at zero tilt during high-wind events

   These factors can significantly reduce lateral and uplift forces, lowering total anchor count and civil scope.

4. How does water-level variation affect the system? Show answer

   Expected water-level fluctuation is incorporated into mooring design. Systems are designed to remain stable across the anticipated operating range.

5. What happens during drought conditions? Show answer

   AccuSolar systems are structurally rigid and buoyant enough to safely rest on the bottom of a reservoir if water levels drop significantly, provided the bottom profile is reasonably flat. This concept of the float solar array sitting on the bottom is also applicable to storm water retention ponds and flood zone applications.

Electrical Configuration & Safety

1. Where are inverters and transformers located? Show answer

   Inverters and transformers are typically installed on shore. This simplifies permitting, improves accessibility, and aligns with current U.S. regulatory norms. AccuSolar works with EPCs and their electrical engineering for clean cable management and routing to shore of the DC wiring.

    

2. How are electrical cables protected in a floating environment? Show answer

   Cabling is routed using standard solar practices with additional waterproofing, strain relief, and controlled suspension above or below walkways. Electrical isolation and grounding strategies are coordinated with the project’s electrical engineer. On most AccuSolar projects, all cabling is above-the-waterline minimizing any stray current impact and allows for safe and easy O&M access.

3. Is floating solar electrically safe? Show answer

   Yes. Floating solar systems follow the same electrical safety principles as land-based systems, with additional protections for moisture, movement, and access control. AccuSolar systems are designed with streamlined bonding approaches that can reduce installation labor compared to some alternative FPV configurations.

Performance, Yield & Tracking

1. Does floating solar produce more energy than ground-mounted solar? Show answer

   In many cases, yes. Floating solar benefits from:

   • Lower operating temperatures due to water-based cooling
   • Increased bifacial gain from high-albedo float surfaces
   • Improved airflow around modules

   AccuSolar uses a conservative assumption of approximately 15% yield uplift relative to comparable ground-mounted systems, subject to site conditions and independent validation. AccuSolar is also in the process of securing usable data to validate these assumptions.

2. Does AccuSolar offer tracking or tilt adjustment? Show answer

   AccuSolar systems support fixed tilt, seasonal tilt adjustment, and optional daily tracking configurations. Seasonal adjustment also provides a risk-management benefit by enabling low-tilt stow during extreme weather. Fixed tilt design can accommodate any tilt angle required for optimal efficiency driven by project location.

Operations, Maintenance & Longevity

1. What maintenance is required for floating solar systems? Show answer

   Typical O&M includes:
