“…Finally, what impact do political factors such as one's political party affiliation have on the decision to install rooftop PV systems in the United States? Lemay et al (2023) focus on a large dataset to shed light on this and related questions. Their analysis shows that the fraction of people voting Democrat in a region has a positive effect on PV system installations.…”

“…Rooftop solar is growing rapidly in the United States, paralleling the growth of solar more broadly (rooftop solar accounted for 40% of installed renewable energy and 25% of new renewables in 2021, according to Joshi et al 2021). Solar plants can be classified into three main categories by size: distributed/rooftop, commercial, and utility, from smallest to largest (Lemay et al 2023). Of these, rooftop solar is the least common and the most expensive, but it offers a number of advantages that commercial or utility scale solar does not (Lemay et al 2023).…”

Rooftop solar is one of the fastest growing sources of energy generation in the United States, offering owners lower electric bills and greater independence from the grid. However, it faces two ongoing challenges that limit growth: a slowdown in demand and large gaps in installation rates along racial and income lines. These gaps persist even after accounting for factors that correlate with income and race, such as solar installation infrastructure. Together, these challenges threaten to both inhibit progress on climate mitigation and worsen existing energy inequality. This article assesses possible drivers of both problems using a large nationally representative survey focused on consumer attitudes towards rooftop solar. I find that perceived affordability is the greatest concern across all subgroups and that Americans are, on average, pro-rooftop solar across all dimensions. Most notably in light of existing explanations for socioeconomic divides, Black respondents are more pro-rooftop-solar than white respondents. Important dividing lines on solar attitudes include homeownership, partisanship, age, education, and geographic solar potential.

“…These circumstances are not reflected in all countries with solar insolation levels suitable for small scale solar PV. For example the level of penetration in U.S. residential buildings is currently less than 1% [5]. However, 100% renewable energy scenario modelling of U.S. electricity demand predicts that solar power will dominate the generation mix [6], and undoubtedly this will mean that small-scale systems will play a significant role in the future [7].…”

Optimising generation and energy storage in the transition to net zero power networks

As electricity networks plan to achieve net-zero emissions, the role of private behind-the-meter (BTM) generation and storage becomes increasingly important. Two key questions arise for planners: how much BTM will there likely be in the longer term; and what impact will this have on network generation and storage? The combination of high insolation and reducing cost of small-scale solar PV systems in Western Australia has led to a rapid and ongoing take-up of private generation which already supplies around 20% of demand (around one third of houses have rooftop solar), and declining midday network loads, which will likely become negative before 2030 at some times of day and year. However, the market operator has consistently underestimated the rate of private penetration, leading to inadequate planning for the future network. Most published research focusses on network scale renewable generation but neglects the impact of private generation and storage. In contrast, this article presents a model of the integrated system to 2050, projecting the likely scale of BTM generation and identifying the optimal form of network renewable energy and storage to achieve net zero emissions. By 2050 BTM generation will likely supply around 50% of the total annual demand of 54,000 GWh pa. Given the diurnal and seasonal shape of the resulting network load and projected renewable generation costs, onshore wind energy will be the most cost optimal generation source, supplemented by smaller capacity offshore wind, wave and solar PV facilities. Network storage in the form of batteries and pumped hydro will be required, but significant curtailment will still be necessary to optimally match supply with demand. Network generation and storage costs per MWh of network load into the future are likely to be similar to, or lower than existing costs (∼$85/MWh) with the range of technologies considered in this study.
