INDIAN LAND - Peter Manfre's power meter sometimes runs backwards.
Manfre is working with York Electric Cooperative in a net metering project. He collects solar power at his home on Henry Harris Road. What solar energy his home doesn't use goes back onto the power grid to be used by other customers of the utility.
Manfre's system has 24 panels that collect solar power. They work best on cold, clear fall days, he said. On a recent overcast, chilly day, the system was likely generating almost nothing, maybe 300 watts, he said.
