Project Summary

Installation of 4,780,600 W DC (4.7MWDC) floating solar (floatovoltaics) PV system at Healdsburg Water Treatment plant. The system floats on 2 collecting ponds at the facility and consists of 11,660 – 410-Watt PV modules. Floating solar helps minimize the evaporation of the pond, helps control algae and makes use of otherwise wasted space. Designed and built by Collins. The facility has a special requirement of needing to inspect the pond liner at both ponds in a 5-year period, we designed arrays that can be decoupled and repositioned – this would allow the owners to drain the pond and inspect the liner – all while the system still produces power from the sun. At the time of completion, it was the largest floatovoltaics system in the USA.
