A new study has investigated the application of magnetized nanofluids for thermal regulation and electrical performance improvement of solar panels. Heat accumulation in photovoltaic panels is a critical factor that reduces their efficiency, as an increase in temperature decreases electrical energy production. This research proposes an innovative solution using an active cooling system based on nanofluids, which are fluids with suspended nanoparticles, to dissipate excess heat and optimize energy conversion.

The method employed involves circulating a nanofluid through a piping system attached to the back of the solar panel. The novelty lies in the application of an external magnetic field to manipulate the nanofluid flow, seeking more efficient heat transfer. Nanofluids, due to their enhanced thermal properties compared to base fluids, are promising candidates for these applications. Magnetic control allows influencing the trajectory and velocity of the nanoparticles, thereby optimizing heat extraction from the panel.

Preliminary results from this approach suggest a significant improvement in both thermal regulation and electrical performance of solar panels. By maintaining the operating temperature within optimal ranges, the degradation of photovoltaic efficiency is minimized. This technology could have a considerable impact on the viability and profitability of solar installations, especially in hot climates where overheating is a persistent problem. The ability to adjust nanofluid flow using magnetic fields offers additional flexibility to adapt the system to different environmental and operational conditions.
