Solar Tractor

Why not haul a solar farm to power a Tractor. If agricultural tractors already carry implements 160 feet wide? Question- what solar panel size is towable?

• Largest seeders are 160 feet wide. [1]. 120' appears common.
• 80 feet appears common - [2]
• JD DB90 and DB120 are the largest drills - 36 and 48 rows, 90 and 120 feet, respectively. [3]

Towable Solar Panel

• Let's take 30 meter wide by 5 meter for the solar array, riding right above the implement. Power produced - 150 watts per square meter. Times 150. 22.5kW. Not a lot. But enough for autonomous operation at slow speed.
• 180 hp towable panel. Take Max of about 60 meters. Widen the 5 meter by 3 via telecoping out the same distance each way. Have 15m x 60m. The 22.5 kW becomes 135kW electric. That is sufficient. Lightweight fiber composite plastics could do the trick for support structures. Panels telescope in for wind protection.

Slow Moving Autonomous Tractors

Q:What about your continious energy output? How much kw do you target?

That's now the point. Under solar operation, you will need only 100W to make this practical, as this is a slow moving device. A standard panel is 300W. I would use 1-2 panels for 600W to cover ample acreage. We could make it as large as 10kW

easily if needed.
