Residential solar photovoltaic installations can be encouraged with funding mechanisms that cost taxpayers nothing.


The Property Assessed Clean Energy (PACE) program is a national initiative designed to promote investment in solar photovoltaics by commercial, nonprofit, and residential property owners. Its central feature is to provide low-cost, long-term funding, which is repaid as an assessment on the property's regular tax bill, as is done for sidewalks and sewers, for example. Spurring such investment clearly is a good goal, but is the program effective? Ameli et al. used a natural experiment in northern California to test the capacity of PACE, finding that it has been a great success, more than doubling residential photovoltaic installations in the region at no cost to the taxpayers.
