EP1 Podcast "Conversas com Boa Energia" | Pedro Salomé (INL) e César Martins (Chemitek) | 03.03.2026

The podcast episode features a conversation between Pedro Salomé from the International Iberian Nanotechnology Laboratory (INL) and César Martins, CEO of Chemitek, about integrating photovoltaic panels into agricultural land to support sustainable energy and food production. They discuss the concept of agrovoltaics (AgroPV), which originated in Germany about 10-15 years ago, and its importance in addressing land use conflicts. Pedro highlights that solar energy received by Earth in one hour could power the planet for a year, and César notes that only 8 minutes of annual solar energy would meet 2025 energy needs. They explain the challenges and opportunities of AgroPV, including social acceptance, legislation, and technological adaptations. Pedro mentions that in Italy, some crops like tomatoes benefit from shading, increasing yields despite reduced solar panel output. César discusses Chemitek’s role in developing cleaning products for solar panels, emphasizing the need for biodegradable and eco-friendly solutions, and the unique challenges of cleaning panels in agricultural settings. They also explore the use of drones for cleaning, which is particularly suited for AgroPV due to the non-uniform layout and height of panels. The project involves creating prototypes and pilot installations, with initial results expected in about two years. They also address the need for national suppliers and the importance of demonstration projects to build trust among farmers.
