Abstract

A solar panel assembly includes a solar panel having a frame and a solar harvesting surface held by the frame; and a shield assembly having a solar shield movable between an operating position and a shielding position and a heat sensitive element. The solar shield is configured to automatically assume the shielding position after the heat sensitive element reaches and/or exceeds an activation temperature.

First claim

What is claimed is:

1. A solar panel assembly, comprising:
a solar panel having a frame and a solar harvesting surface held by said frame; and
a shield assembly having a solar shield movable between an operating position and a shielding position and a heat sensitive element, said solar shield being configured to automatically assume said shielding position after said heat sensitive element at least one of reaches and exceeds an activation temperature;
wherein said heat sensitive element at least one of melts, chars, disintegrates, boils, and bursts at said activation temperature.

2. The solar panel assembly according to claim 1 , wherein said heat sensitive element is a fusible link configured to hold said solar shield in said operating position.

3. The solar panel assembly according to claim 2 , wherein said activation temperature is a melting temperature of said fusible link, said solar shield being configured to move said shielding position after said fusible link at least one of reaches and exceeds said melting temperature.

4. The solar panel assembly according to claim 2 , further comprising a tensile member connected to said solar shield and configured to pull said solar shield into said shielding position, said fusible link preventing said tensile member from pulling said shield assembly into said shielding position.

5. The solar panel assembly according to claim 4 , further comprising a track connected to said frame, said tensile member being held between said track and said frame.

6. The solar panel assembly according to claim 4 , wherein said tensile member is connected to an end of said frame such that said tensile member is configured to pull said solar shield across a length of said solar harvesting surface.

7. The solar panel assembly according to claim 4 , wherein said solar shield is a roll of material.

8. The solar panel assembly according to claim 2 , wherein said fusible link prevents gravity from pulling said solar shield into said shielding position from said operating position.

9. The solar panel assembly according to claim 1 , wherein said shield assembly includes a hinge connecting said solar shield to said frame, said hinge being biased toward said solar harvesting surface.

10. The solar panel assembly according to claim 9 , wherein said heat sensitive element is a fusible link connected to said solar shield and preventing said hinge from biasing said solar shield toward said solar harvesting surface.

11. The solar panel assembly according to claim 10 , wherein said frame includes at least one leg, said fusible link being connected to said at least one leg.

12. The solar panel assembly according to claim 1 , wherein said heat sensitive element is a thermal gate configured to hold said solar shield in said operating position.

13. The solar panel assembly according to claim 12 , wherein said thermal gate is configured to release said solar shield into said shielding position one of at and above said activation temperature.

14. A solar panel assembly, comprising:
a solar panel having a frame and a solar harvesting surface held by said frame;
a shield assembly having a solar shield movable between an operation position and a shielding position, said solar shield at least partially covering said solar harvesting surface in said shielding position; and
a heat sensitive element associated with said solar shield and defining an activation temperature, said heat sensitive element allowing said solar shield to assume said shielding position from said operating position after said heat sensitive element at least one of reaches and exceeds said activation temperature;
wherein said heat sensitive element at least one of melts, chars, disintegrates, boils, and bursts at said activation temperature.

15. The solar panel assembly according to claim 14 , wherein said heat sensitive element is a fusible link holding said solar shield in said operating position.

16. The solar panel assembly according to claim 14 , further comprising a tensile member connected to said solar shield and configured to pull said solar shield into said shielding position, said heat sensitive element preventing said tensile member from pulling said shield assembly into said shielding position below said activation temperature.

17. The solar panel assembly according to claim 14 , wherein said heat sensitive element impedes said solar shield moving to said shielding position from said operating position until after said heat sensitive element at least one of reaches and exceeds said activation temperature.
