Construction on a massive solar energy facility slated for open space off Charge Pond Road is scheduled to be finished this spring after the Zoning Board of Appeals approved the project Wednesday night.

The approval process started in October when representatives from Bluewave Capital first appeared before the Planning Board. The Boston-based solar developer plans to install 32,724 solar panels in four different arrays on land near the intersection of Route 25 and Charge Pond Road.

The panels will generate roughly 12 megawatts of electricity, which is enough to power approximately 490 medium-sized homes. The area is home to a mix of cranberry bogs and forests.

Attorney Richard Serkey, representing Bluewave Capital, and Lexi Barlow, a project manager for Bluewave Capital, appeared before board members Wednesday night for final approval.

Barlow said work on the project will begin once the decision’s 20-appeal period expires. She estimated that the project will be “mechanically complete” by this spring.

At previous meetings, members expressed concerns regarding screening measures. Others said clearing the land, which is home to an array of wildlife, would have a negative impact on habitat.

Bluewave officials addressed the screening concerns in plans, assuring board members that an appropriate buffer will be put in place. They also noted there are no homes within sight of the arrays.

The project also received approvals from the Planning Board and the Conservation Commission.
