Increasing the penetration of photovoltaics (PV) reduces the marginal grid value of PV electricity. Various strategies have been proposed for preserving this value. We analyze the net value (accounting for both cost and grid value) of these strategies in the United States. We find that...

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...

Despite improving economics, low- and moderate-income (LMI) households remain less likely to adopt rooftop solar photovoltaics (PV) than higher-income households. To date, researchers and policymakers have focused on demand-side drivers of PV adoption inequity, but supply-side factors could also...
