The energy that can be obtained from a 260 watt panel (1000 watt-hours per day) is directly from NREL and is not hypothetical. The watt-hours per mile is based on direct measurements by a poster on this forum and reported ranges by several posters.
The output voltage only has meaning when the amperage is specified. That is why I used energy units. Watts (power) = Volts x Amps. Energy is watts integrated over time or watt-hours.
A controller can maximize the charging of the battery pack but the absolute energy from the panel is limited by the panel technology, the size of the panel, it's orientation to the sun, the latitude, hours of exposure, and the climatic conditions. On average, you won't see more than 1000 watt-hours per day from the panel and probably a lot less unless you leave the cart outside all day. I ignored the inefficiencies in the controller - the energy to the battery pack will probably be 5% less due to inefficiencies in the controller.
Feel free to post your own numbers.

Unlike as we have in real time testing and use over the last few years.
You are welcome to see the cart when they are at the squares.
To debate your numbers here is pointless, especially when you have no idea what the output voltage is nor how the controller was engineered.
