A 20,000-panel solar power-generating field installed at the site of a former town landfill in Canton is still catching flak from unionized electricians despite being lauded by local and state officials as a hugely beneficial project for everyone.

“This project has turned the old landfill site into a generator of power and economic development,” state Energy and Environmental Affairs Secretary Rick Sullivan said in a recent interview. “It’s a win-win, as the project is expected to save Canton thousands of dollars on its power bills and help limit the Commonwealth’s reliance on foreign sources of energy.”
