Q & A

What is the product that Engineer 775 is excited about sharing in the video?

The product is a solar tracking system from Pursuit Solar that uses an industrial wax, a piston, and a parabolic dish to track the sun without the need for motors, controllers, or PLCs.

Why was Engineer 775 particularly interested in this solar tracker?

Engineer 775 was intrigued by the mechanical engineering aspect of the tracker, which operates without any electronic components such as motors or controllers.

How does the solar tracking system work mechanically?

The system uses the heat from the sun collected in a parabolic dish to melt industrial wax, which then moves a piston. This piston motion drives the tracking mechanism.

What is the purpose of the parabolic dish in the solar tracking system?

The parabolic dish is used to collect and concentrate sunlight onto a collector tube, which heats the wax inside, initiating the tracking mechanism.

How much weight can the demo unit of the solar tracker lift to demonstrate its strength?

The demo unit can lift approximately 2,000 pounds of blocks about 4 inches, showcasing the force it can exert.

What is the estimated increase in solar production with the use of this tracking system?

The tracking system is estimated to increase solar production by about 20%.

What is the main drawback mentioned by Engineer 775 regarding the solar tracker's operation?

The main drawback is that if the tracker doesn't start tracking due to overcast conditions in the early morning, it cannot catch up with the sun's position throughout the day.

What concept does the solar tracker use to follow the sun throughout the day?

The tracker uses the concept of heliotropism, similar to how a sunflower follows the sun from morning to evening and then resets.

What is the standard model's capacity in terms of the number of solar panels it can hold?

The standard model is designed to hold 12 72-cell panels, and there is an 18-panel version available.

What is the significance of the piston in the demo unit's demonstration of the tracking system's strength?

The piston in the demo unit moves and lifts a cable, which in turn lifts 2,000 pounds of material, demonstrating the system's mechanical strength and reliability.

Why might someone choose a solar tracker over a fixed ground mount?

A solar tracker might be chosen if there is limited space, as it can significantly increase energy production without needing to add more panels. It's also a good option for those interested in innovative technology.

What is the name of the company and the contact person mentioned for more information about the solar tracker?

The company is Pursuit Solar, and the contact person is Eddie Bug, the owner.
