Revolutionary 6MW Floating Solar Array Transforms Ohio’s Reservoir Into Clean Energy Powerhouse

Monroeville, Ohio is making waves in renewable energy with construction beginning on the state’s largest floating solar array. The 6-megawatt installation on the town’s reservoir will generate over 7,500 megawatt-hours of clean electricity yearly when it becomes operational in early 2026.

The project saves more than 30 acres of land compared to traditional ground-mounted solar systems. That’s because floating solar needs less space – about 7 acres per megawatt less than land-based arrays. This innovative approach prevents conflicts with farming, housing, or business development.

Floating solar delivers energy with a smaller footprint, preserving precious land for agriculture and development.

D3Energy is developing the project, which will be owned by Gardner Capital. The company has extensive experience with over 10 installations already operational in Florida alone. Once complete, the system will operate under a long-term Power Purchase Agreement, providing stable energy costs for the community. The electricity will feed directly into the local grid, powering homes and businesses with renewable energy.

The environmental benefits are significant. The floating panels will reduce carbon dioxide emissions, with each megawatt saving approximately 430 kg of CO2 per megawatt-hour generated. Unlike fossil fuels, solar energy produces minimal air pollution and helps reduce the community’s overall carbon footprint. The array may also decrease water evaporation and limit algae growth by partially shading the reservoir. The water cooling effect provides enhanced efficiency compared to traditional land-mounted systems.

Technically, the system features a modular design with solar panels, inverters, transformers, and underwater cables. The installation includes maintenance walkways and a mooring system to withstand weather conditions. Real-time monitoring will guarantee reliable operation.

The Monroeville project follows Ohio’s first floating solar installation at Del-Co Water, which uses 2,600 panels to generate 1.5 megawatts. Both systems employ the Hydrelio® floating technology from Ciel & Terre, a global leader with over 1.5 gigawatts of similar installations worldwide.

Local contractors from ARP Solar will help build the array, creating jobs in the area. The project establishes a model for small towns to lead in renewable energy innovation without disrupting existing land use. Its success could inspire similar installations across rural Ohio communities and beyond.
