Week 16: Final Presentation

The discovery channel has recorded footages of Spartan Superway. Matthew Dianich, the team lead of full-scale solar team, has introduced the work of Solar team for the program. The team finished the installation method of the gutter system. The final presentation for Solar team was held in E135 at 11:30 AM. The team has been able to complete the prototype that is quite identical to what was designed on Solidworks.

Week 15: Completed the Solar Rack Design & Building the Water Gutter

This week, the Solar team figured out a way to mount the water gutter to the canopy. Overall, the team was able to finish everything on time. The last part of the project that solar team needs to complete is to mount the tarps on the canopy for the waterproof purposes. We are still waiting to get tarps order to come. The team's plan is to complete the entire project by Friday next week.

Week 14: Finished the Assembly

This week, the solar team finished with the final assembly. Below is the final assembly that we have. The team is very happy with the result. For next week, we will put the solar panels on the solar track and test the circuit to make sure everything works.

Week 13: Cuts Finished

Below is the solar "rib" design before self-tapping screws have been applied to the gusset plates.  The team is very pleased with how the design looks and the team hopes that the rest of the fabrication process will be smooth as well.  The team is planning on installing the gusset plates in the upcoming days.

Week 12: Presentation #2 on 4/11 (4/12/2018 - 4/18/2018)

The presentation was completed at Spartan Superway Design Center on April 11th, Wednesday. The hand calculation of CFD results and the maximum wind speed may need to be altered per the feedback from Dr. Furman. Batteries, charge controllers, parallel y-connectors, extension cables, and MC3 to MC4 converter have been purchased. Wires, gutter, and wooden fake panels will be ordered as soon as possible.

Week 11: Manufacturing and Finishing up the BOM (4/5/2018 - 4/11/2018)

This week, the solar team focused on manufacturing some of the main structural components for the solar panels. Galvanized Steel Sheet metals in 16Ga and 18Ga were tested and 16Ga was selected due to its rigidity. The sheet metals were purchased at Acosta Sheet Metal Manufacturing. Bill of materials include all the details such as total cost including tax and discount as well as the dates of purchase. The presentation was prepared to incorporate all the progress the team has made since the spring break.

Week 10: C-Channels & Solar end clamps Shipping | Cutting C-Channels & CFD (3/29/2018 - 4/4/2018)

Throughout the spring break, the team has completed the following tasks. On 3/26/2018, the team has rented a 26-feet-long U-Haul truck to load and unload the 20-feet-long c-channels from Lord&Sons, Inc. Also, gutter and gutter guards/covers were purchased on the same day. On Tuesday, the team has purchased solar extension cables and solar end clamps. For the rest of the spring break, the team has practiced cutting c-channels with spare scrap metals in the shop. Few of straight sections of c-channels have been cut as well. Also, the team has completed the CFD using Ansys on solar panels regards to the wind lift encompassing the lift and drag coefficients.
