From homes to industries, photovoltaic systems have generated significant savings for consumers, as shown by research conducted by Enervis, a consulting firm specializing in the energy sector.
At the request of BSW-SolarThe consultancy analyzed the impact of photovoltaic installations on electricity prices on the energy exchange. The initiative came from the association after the German Federal Minister of Economy, Katherina Reiche, announced cuts in subsidies directed at solar energy.
The aim of the research is to prove the photovoltaic efficiency not only for the consumer economy, but also for the national economy, which has earned up to 1,3 billion euros from electricity exports.
Savings of 120 euros in 2024
According to experts, without the photovoltaic energy generated during 2024, the price of electricity would have been, on average, 15% higher. In both residential and industrial sectors, solar energy played a significant role in the economy, accumulating €6,1 billion in savings last year.
Even households without their own photovoltaic system benefit, saving up to 50 euros a year thanks to the portion of solar energy injected into the electricity grid.
“Thus, it is not only the approximately three million homes with their own solar roofs that benefit from affordable solar energy, but all citizens. The moderating effect of solar prices on the electricity market is already benefiting the economy as well,” says Carsten Körnig, CEO of BSW-Solar.
In the industrial sector, companies consuming ten gigawatt-hours recorded savings of up to 120 euros in 2024.
Positive forecasts for the coming years.
The trend is that, in the coming years, solar energy will continue to reduce electricity costs, according to a study by Enervis.
With the further expansion of photovoltaics planned until the end of 2025, the forecast is that the wholesale price of electricity will be reduced by 21% by 2030. In numbers, this means that private residences should save more than 70 euros per year, while industrial companies consuming ten gigawatt-hours could achieve annual savings of 180 euros.
Subsidies under threat
With this study, BSW-Solar seeks to demonstrate that expanding government incentives can accelerate the growth of photovoltaic installations, generating benefits for the population, industry, and the economy as a whole.
According to the association, however, this will only be possible if there are no cuts to the subsidies currently planned by the German government. "Attractive and reliable conditions provide the necessary groundwork for us to continue reaping the benefits of the energy transition in the form of effective climate protection and price moderation," says Körnig.
Recent research indicates that removing incentives would have a direct impact on the adoption of solar systems. A survey by BSW-Solar itself with 132 installation companies shows that only 4 out of 10 residential consumers would invest in a photovoltaic system without subsidies.
This scenario is reinforced by data from YouGov: among 248 homeowners who planned to install solar panels, only 40% would likely stick with their decision if the subsidy were reduced or eliminated. Only 12% stated that they would definitely install the system in that context.
Public opinion also reflects this stance. A survey of 2.355 respondents revealed that about 8 out of 10 support maintaining policies that promote solar energy.
Given the combination of technical data and popular support, the solar sector and BSW hope that the Ministry of Economy will reconsider its plan to reduce or eliminate incentives for the expansion of photovoltaics in the country.
