A rooftop photovoltaic solar system is disclosed. The solar system comprises a plurality of photovoltaic modules forming a rooftop array, the rooftop array having at least one edge and a wind deflector positioned along the edge of the rooftop array, the wind deflector constrained in a first configuration by a fuse. In the first configuration the wind deflector comprises a deflecting portion adapted to deflect wind blowing on the rooftop above the rooftop array and a ventilation portion having a plurality of openings, the openings positioned to permit airflow under the rooftop array. The wind deflector assumes a second configuration upon release of the fuse. In the second configuration, the deflecting portion is elevated from the first configuration and the ventilation portion is positioned to permit less airflow through the plurality of openings than in the first configuration.
