Living near the beaches offers excellent benefits due to the abundant hours of high solar luminosity. However, for outdoor-installed technology, the marine environment presents a specific set of atmospheric challenges that must be known.
In regions like the Maresme coast or the Baix Llobregat, we face the particularities of the coastal climate:
Saltpeter, a silent brake on performance
Humidity and the sea breeze lift vapor carrying salt particles. When the panels dry in the sun, this saltpeter forms a light, matte whitish film on the glass, slowing down the sun's proper incidence by small percentages (5% to 10%). Unlike clean rains, this deposit requires attention. With a simple cleaning session every few months using water (without aggressive abrasives), the system will instantly recover its maximum nominal production.
Mechanical robustness against windstorms
Aside from the panel's glass, it is vital to look at the quality of the secondary structure upon which the photovoltaic system rests (mounts and fixings). Due to oceanic conditions, we install aerodynamic structures made of reinforced stainless steel. To prevent aerodynamic lifting effects against intense hurricane-force gusts, we apply strict mechanical load calculations to the installation's anchors.
