Energy bills are falling in Germany due to solar power, reinforcing the need for incentives for photovoltaic generation.

Research reveals that solar energy reduced electricity prices in Germany by up to 15% in 2024, generating billions in savings and strengthening the debate about maintaining incentives for photovoltaics.

The expansion of solar energy In Germany, it attracted attention after the publication of a study commissioned by German Solar Energy Association (BSW-Solar). The analysis, conducted by the consulting firm Enervis, shows that photovoltaic systems not only ease the financial burden on consumers, but also guarantee significant gains for the national economy. Amid discussions about cuts in subsidies, the results rekindle the defense of the continuation of public incentives.

Solar energy is already reducing costs for consumers and for the country.

According to Enervis, the presence of solar energy was decisive for the electricity market in 2024. According to the study, without photovoltaic generation, the price of electricity would have been, on average, 15% higherThis difference translates into €6,1 billion in savings over the year, benefiting both households and industries.

Furthermore, even those who don’t have their own system benefit. Research indicates that households without photovoltaic panels can save around… 50 euros per yearthanks to solar energy fed into the grid. This collective impact was reinforced by Carsten Körnig, CEO of BSW-Solar:

“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.”

Industrial performance and impressive results in 2024

In the manufacturing sector, the results are also noteworthy. Companies with an annual consumption of ten gigawatt-hours recorded savings of up to 120 thousand euros in 2024. This data reinforces the importance of photovoltaics in industrial competitiveness at a time of high energy demand.

In addition to direct savings, the study highlights another relevant factor: Germany collected approximately 1,3 billion euros with the export of electricity, driven by increased supply and the stability generated by solar energy in the system.

Outlook suggests even cheaper energy by 2030.

Enervis projects that the downward trend will continue in the coming years. With the planned expansion of photovoltaics until 2025, the wholesale price of electricity may fall. 21% by 2030.

If confirmed, the reduction will allow households to save more than 70 euros per yearwhile companies that consume ten gigawatt-hours could achieve annual savings of 180 thousand eurosThese figures reinforce the strategic role of solar energy in the energy transition and price stability.

Debate on subsidies and concerns of the sector.

The study comes at a crucial moment, as statements by the Minister of Economy, Katherina Reiche, have raised concerns about possible cuts to incentives. For BSW-Solar, the data proves that expanding subsidies is essential to accelerate the adoption of solar energy and prevent setbacks.

Körnig reinforces this view by stating:

“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.”

However, recent surveys show that without financial support, participation would plummet. Research with 132 installation companies indicates that only 4 out of 10 consumers They would invest in a photovoltaic system without subsidies.

Public opinion and the risk of slowdown.

Data from YouGov confirms this scenario. Among 248 homeowners who planned to install solar panels, only 40% They would maintain their decision even if subsidies were reduced or eliminated. Only 12% would proceed with the installation with complete certainty.

Social perception also reinforces the defense of maintaining support: a survey of 2.355 respondents indicates that 8 out of 10 Germans They are in favor of continuing policies that encourage solar energy.
