Abstract

The present invention is directed to a process for manufacture of a solar panel string assembly for a solar canopy including: horizontally aligning two solar panel support channels substantially parallel to one another; applying an adhesive with a robotic tool to an upper portion of the solar panel support channels, the robotic tool comprising a fixed track aligned parallel with the two solar panel support channels, a robotic arm assembly movably supported by the track, a positioning member for adjusting the position of the robotic arm assembly along the track, and wherein the robotic arm comprises an adhesive applicator and a vacuum lift component; and lifting with the vacuum lift component of the robot arm assembly of the robotic tool and aligning a solar panel on top of the two solar panel support channels near opposing edges of the solar panel.

Claims (17)

1. A process for manufacture of a solar panel string assembly for a solar canopy, the process comprising:

(a) horizontally aligning two solar panel support channels substantially parallel to one another;

(b) applying an adhesive with a robotic tool to an upper portion of the solar panel support channels, the robotic tool comprising a fixed track aligned parallel with the two solar panel support channels, a robotic arm assembly movably supported by the track, a positioning member for adjusting the position of the robotic arm assembly along the track, and wherein the robotic arm comprises an adhesive applicator and a lift component; and

(c) lifting with the lift component of the robot arm assembly of the robotic tool and aligning a solar panel on top of the two solar panel support channels near opposing edges of the solar panel; and

(d) repeating the lifting step (c) until the desired number of solar panels are aligned side-by-side on the two solar panel support channels, thereby forming a solar panel string assembly.

2. The process of claim 1 , wherein the solar panel string assembly lay parallel with the ground surface for loading on a truck for transportation to the job site.

3. The process described in claim 1 , further comprising electrically connecting the plurality of solar panels to one another in series.

4. The process described in claim 1 , further comprising attaching a direct current to alternating current inverter to the solar panel support channel and electrically connecting the inverter to the plurality of solar panels.

5. The process described in claim 1 , wherein the solar panel support channels are “Z”-channels.

6. The process described in claim 1 , wherein the solar panel support channels are “C”-channels.

7. The process described in claim 1 , wherein the solar panel support channels comprises integral alignment tabs for aligning the solar panels on the solar panel support channels.

8. The process described in claim 1 , wherein the plurality of solar panels is from about 4 to about 20 solar panels.

9. The process described in claim 1 , further comprising manufacturing the solar panel support channel at a solar canopy construction site using rolled sheet metal form extrusion.

10. The process described in claim 1 , further comprising attaching an eye bolt to the solar panel string assembly for lifting the solar panel string assembly during construction.

11. The process described in claim 1 , wherein the lift component comprises a vacuum lift tool.

12. The process described in claim 1 , wherein the step of horizontally aligning two solar panel support channels substantially parallel to one another occurs on a surface sufficiently angled so as to provide worker access beneath finally assembled solar panel string assembly for electrical connections.

13. The process described in claim 1 , wherein after forming a solar panel string assembly the assembly is sufficiently tilted so as to provide worker access beneath for electrical connections.
