The Mediterranean is one of the regions with the greatest potential for solar photovoltaic energy. However, a phenomenon that is becoming increasingly frequent threatens its profitability: dust episodes from the Sahara Desert, commonly known as calima.
A recent study by the HUN-REN Research Centre in Hungary has highlighted the impact of these events. Data show that, in the most extreme cases, photovoltaic production can fall by up to 50% in countries such as Spain, Portugal, France, Italy, and Greece.
Impact on the solar sector
These dust episodes not only make the sky hazy; they also have direct consequences on the performance and reliability of photovoltaic installations:
- Reduced production: The density of particles in the atmosphere blocks solar radiation, reducing the energy reaching the panels and causing significant production losses.
- Lower profitability: Less energy generated means less savings or reduced revenues for the installation.
- Increased maintenance: Dust adheres to the panels, reducing efficiency and requiring more frequent cleaning, which entails additional costs.
- Uncertainty in planning: Production forecasts often overlook these phenomena, leading to deviations from initial estimates and affecting project financing.
Impact data
According to the Hungarian study, production losses in Spain during episodes recorded between 2019 and 2023 were:
- Moderate episodes: Average reduction of 25% to 40%.
- Intense episodes: Estimated losses between 16.3% and 19.8%.
How does Solventa6 protect your installation?
At Solventa6 we are aware of these challenges and have developed solutions to minimise their impact and ensure maximum efficiency of your installation:
