California regulators are eyeing sharp reductions in subsidies for residential solar systems in  what would be the first major reform to a program that helped jump-start the rooftop solar industry, according to Bloomberg.

As part of a proposed series of changes issued on Monday by a judge at the California Public Utilities Commission, residential solar customers would receive a much lower credit  for excess energy sent to the grid - with credits ranging from around 30 cents per killowatt-hour, to less than 10 cents depending on time of day.
