(Rick Egan | Tribune file photo) This Salt Lake City home is among 35,000 served in Utah by Rocky Mountain Power that are equipped with rooftop solar panels. Electricity generated by such panels but not used by the resident is exported onto the electrical grid and the utility customers are compensated for each excess kilowatt hour they produce. The advocacy group Vote Solar is seeking generation and export data on all of the utility's solar customers to build a case for keeping compensation rates high.
