PECO Energy provided the Philadelphia Housing Authority with a grant of $232,100 for installation of photovoltaic solar energy systems at 18 homes on south-facing homes on Mifflin Street in the Greater Grays Ferry Estates. The grant is part of a $500,000 PECO commitment to support solar power installation in low-income housing in Philadelphia. The Housing Authority estimates that residents using the solar systems will save from $400 to $500 yearly in energy costs.
