PROVIDENCE — The state Renewable Energy Fund (REF) recently made one of its biggest outlays of grants to fund 94 new solar-energy projects.

In all, $1.7 million was awarded to private preparatory schools, low-income housing facilities, a winery, a solar carport and dozens of projects in the discount solar program Solarize Rhode Island.

Schools don’t qualify for the 30 percent federal tax credit and instead received a subsidy covering as much as 75 percent of a project’s cost, the funding coming from Rhode Island’s participation in the multi-state cap-and-trade program known as the Regional Greenhouse Gas Initiative (RGGI). Several of the schools plan to include the solar arrays in classroom studies.
