Active fire-blocking wind deflector

A rooftop photovoltaic solar system comprising:

• 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, wherein 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;
• and
• wherein the wind deflector assumes a second configuration upon release of the fuse, and 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.

A wind deflector held in compression, the wind deflector comprising:

• a planar portion;
• a support portion coupled to the planar portion, the planar portion held in a first position relative to the support portion, the first position causing strain in the wind deflector;
• and
• fuse means retaining the wind deflector in the first position, the fuse means adapted to release at a predetermined temperature, thereby releasing the wind deflector from compression and positioning the planar portion at a second position relative to the support portion.
