New Swiss research shows that PV-driven houses can increase power consumption by a maximum of 11% compared to non-Solar households. This increase is linked to the acceptance of electric vehicles or other devices with a high use, the author of the study notes is not inherently negative or waste.
New research from the University of Bern in Switzerland has shown that the installation of a PV system of a residential roof could increase the power consumption of a household by a maximum of 11%.
The research work analyzed the impact of the so-called Rebound effect, which consists of one Reducing the expected profit of a more source efficient technology as a result of behavioral or systemic change. With regard to residential solar energy, this effect is equal to the change in the electricity consumption of a household as a result of PV current generation.
“This is not The first study that investigates the solar Rebound -effect -there are various studies that illustrate the concept for different contexts, “said researcher Patrick Biegler.”The most important characteristic of my approach is that I can check for the co-adoption of energy-intensive goods together with solar energy. For example, I can illustrate that part of the higher consumption after accepting solar energy is explained by also buying an electric car or comparable electricity-intensive goods. This shows that a solar rebound is not necessarily negative or wasting. “
In the newspaper “Size and decomposition of the solar rebound: evidence of Swiss householdsPublished in the Journal of Environmental Economics and ManagementBiegler explained that his analysis was based on annual data of electricity consumption and detailed information at household level that was taken at 58.104 home homes in single -family home in the Canton van Bern, Switzerland, between 2008 and 2019.
He also used a Supervised Machine Learning (ML) model using regularized gradient stimulation to measure the “non -observed Contrafactual” electricity consumption for households on solar -pv, whereby the analysis takes into account the annual electricity consumption, electricity, peaky prospective, peak -ownedism Electricity price, electricity price, electricity price, electricity price, electricity price, electricity price, electricity price, electricity price, electricity price, electricity price, electricity price, electricity price, electricity price, enigriby, and at the height of the local utility BK.
Because of this analysis, Biegler discovered that the average consumption tends to stay largely unchanged with non-adopted households, while Adopters of Zonne-PV tend to consume more power immediately in the period after adoption. “I estimate a rebound -effect on solar energy between 7.9 % and 11.1 %,” he said. “The evidence suggests that the rebound effect is primarily price-controlled, because proxies indicate relatively small contributions for both income effects and behavioral reactions such as moral licenses.”
The researcher also discovered that the rebound effect is mainly powered by the high capacity of the residential PV systems that are considered in the study, the average of which is approximately 8 kW. “These adopters react stronger to large PV yields on solar energy,” he said, noticed that households who resort to storage tend to show relatively lower rebound effects.
“Solar -Rebound effects are usually observed negatively and are often mentioned as arguments against subsidy programs,” he concluded. “However, my findings suggest that parts of the solar rebound effects can arise from households that further excite their heating and transport modes.”
“At the moment there are no plans to further extend to different segments, because the institutional setting is slightly more complex with commercial and industrial solar owners in Switzerland,” Biegler added. “However, I know few studies that do similar studies into industrial adopters in Germany and Uruguay.”
In February, researchers from Australia and Vietnam published the results of a research work on the short and long-term dynamics of the rebound effect. This article showed that residential solar installations can increase the total electricity demand of a household by around 16.3% compared to non-set households
