A very effective way of quickly deploying solar photovoltaic (PV) systems is the scheme called net metering, also called net energy metering.
This scheme is now in place in 44 U.S. states, opening the floodgates to rapid solar PV deployment in the U.S. What is being called a “net metering war” is now raging in the U.S., with utilities trying to roll-back net metering, especially its pricing model called parity pricing, which credits solar rooftop owners the full retail price for any surplus they export to the grid.
In some U.S. states, the utilities are succeeding. Here in the Philippines, the utilities won the war even before a single shot was fired, by drafting themselves the “net-metering” rules in the country.
For a review of the net metering debate, and the arguments which show that the utilities position actually leads to the double-charging of their net-metered customers, please download my piece “Net metering opens the floodgates to solar rooftops and other renewables“.
