Massachusetts may soon host the first US solar on highway sound barriers

Massachusetts-based Ko-Solar wants to put solar panels in places no one really notices, like on industrial building roofs, in parking lots, and sound barriers on highways. It may finally get its chance, on Interstate 95 in the Boston area. And that would be a US first.

Ko-Solar is particularly interested in transportation structure, so it’s developing a pilot project with the Massachusetts Department of Transportation (MassDOT) to put solar panels on a half-mile stretch of sound barriers on Interstate 95, near Boston.

Metal grids will be attached to the sides of 160 concrete sound barriers on the southbound side of I-95, and solar panels will be mounted at an angle. The panels will face the road.

Massachusetts-based Solect Energy will own the installation, and the MassDOT will buy the power the solar panels generate at a few cents per kilowatt-hour cheaper than the basic utility rate.

The pilot project is expected to produce 800 megawatt-hours of power annually. That’s enough to power around 100 households.

The state will observe the installation for a couple of years, observing a number of things. It wants to ensure the metal grids don’t damage the sound barriers and also wants to know how weather affects the solar installation, how and whether the installation impacts the effectiveness of the sound barriers, and whether any glare occurs from the solar panels that could impact drivers.

The pilot is participating in The Solar Massachusetts Renewable Target (SMART) program, which offers incentives for residential and commercial solar projects throughout Massachusetts. Energy News Network points out:

The installation qualifies for an extra 6 cents per kilowatt-hour under a provision that gives a boost to projects constructed over an area also used for transportation purposes. In September, the plan also received a $345,000 grant from the state Department of Energy Resources as part of a program that helps state agencies and colleges pursue clean energy projects. 

This installation will be the first of its kind in the US, and construction is expected to begin in spring 2022. Other countries, such as Germany and Australia, are already attaching solar to sound barriers.
