Previously, we quantified a decline in the marginal economic value of wind and PV with increasing penetration levels based on a long-run equilibrium investment and dispatch model that accounted for operational constraints for conventional generation. We use the same model and data, based loosely...

Residential photovoltaic (PV) systems were twice as expensive in the United States as in Germany (median of $5.29/W vs. $2.59/W) in 2012. This price discrepancy stems primarily from differences in non-hardware or “soft” costs between the two countries, which can only in part be explained by...

Residential photovoltaic (PV) systems in the US are often compensated at the customer's underlying retail electricity rate through net metering. Given the uncertainty in future retail rates and the inherent links between rates and the customer–economics of behind-the-meter PV, there is growing...
