In a context where the energy transition has become crucial, the deployment of solar panels on rooftops is often seen as a logical alternative to maximize the use of existing spaces. However, some voices are raised against this approach, highlighting the difficulties caused by negative prices of electricity and Chinese competition in the photovoltaic market. In France, the debate rages over the strategic choices to adopt, while policymakers try to juggle regulatory obligations and economic realities. In the face of these issues, the decisions made today will determine the place of renewable energy solutions in tomorrow’s national landscape.
Limiting the Deployment of Solar Panels on Rooftops
In the face of environmental challenges, France is often criticized for not sufficiently utilizing solar panels on rooftops. Some studies, such as the one published by Reporterre, demonstrate that the rooftops of already urbanized areas, such as parking lots and other built spaces, should prioritize photovoltaic installation. Nevertheless, some arguments put forward rely on the complexity of the technical and economic integration of these devices within the existing legislative framework. This leads to a limitation of their deployment, whereas their strategic use could be a crucial solution in the face of environmental pressures.
Consequences of Negative Prices on Solar Energy
The negative prices in the energy market represent a challenge for the solar industry. Indeed, when production exceeds demand, the electricity produced must be sold, or even stored at a loss. This phenomenon, heightened during periods of high solar production, illustrates the need to adapt our energy framework to better integrate new renewable sources. Reducing the use of solar panels, rather than investing in improved storage solutions, would only exacerbate this problem.
Chinese Competition in the Photovoltaic Sector
Another significant challenge is the Chinese competition, which dominates the global market for photovoltaic panels. China, thanks to its low production costs and vast manufacturing facilities, floods the international market, making it difficult for European producers to remain competitive. This dominance could push the French government, as reported by Le Figaro, to consider reducing installation subsidies. Rather than restricting the use of solar panels on our rooftops, it would be wise to strengthen our competitiveness by encouraging local innovation and diversifying our supply sources.
