Two Massachusetts cranberry farms have completed their first harvest under solar panels, marking a milestone for renewable energy and wetland agriculture.
Distributed Energy Infrastructure, an engineering, procurement, and construction company, announced the harvest at the Black Cat site in Plymouth and the Ring Road project in Kingston. The company identified the installations as the first agrivoltaic projects to combine wetland cranberry cultivation with solar power generation.
Renewable energy asset manager Greenbacker Renewables owns both facilities, while Distributed Energy Infrastructure directed the installation and construction work. Cranberry farmer Iain Ward, who manages agricultural operations on the bogs, worked directly with engineers during the design and construction phases. The collaborative planning aimed to protect the fragile wetland ecology while ensuring that agricultural production could proceed without disruption.
Solar arrays and battery storage capacity
The Black Cat and Ring Road facilities pair elevated photovoltaic panels with utility-scale battery energy storage systems. In total, the two sites deliver 5.4 megawatts of solar power capacity alongside 16.2 megawatt-hours of battery energy storage capacity.
Battery storage plays a critical role in modern electrical networks by absorbing power generated during peak midday sunlight and releasing it during evening hours when electricity demand rises. By capturing excess generation on site, the storage units help stabilize the regional power grid and prevent clean electricity from going unused during periods of high generation.
Agrivoltaics is the practice of co-locating agricultural operations with ground-mounted photovoltaic systems on the same land. While traditional utility solar installations often clear open fields and halt farming activities, agrivoltaic arrays elevate panels several feet above the ground so that tractors, harvesters, and livestock can operate below while crops receive sufficient sunlight and moisture.
Financial relief for cranberry growers
The projects provide a critical new source of revenue for the land, where cranberry farming had ceased to be economically viable. Property owners receive predictable lease payments from the solar facilities, restoring profitability to the bogs. Ward earns a management fee for supervising the agricultural work on the sites in addition to revenue generated from selling the harvested fruit.
Cranberries are native North American wetland fruits, and Massachusetts has hosted commercial bogs since the early nineteenth century, primarily across Plymouth County and Cape Cod. In recent years, local growers have faced sharp declines in wholesale fruit prices, heightened labor and fuel costs, and global market gluts, leaving many historic bog owners struggling to maintain margins.
Advocates of dual-use solar argue that combining clean energy with food production offers a sustainable lifeline to independent growers without consuming scarce farmland. The completed harvest in Plymouth and Kingston provides commercial evidence that sensitive wetland crops can continue to yield fruit while generating renewable electricity.
