  • Pick a route, run it multiple times through different scenarios - without array, with array, different drivers

    • Vary route after you get a good feel of one type of terrain(s); try other ones

    • Aerodynamic drag for a given speed is important info (warning)

    • Attempt to identify impacts of different weather conditions (winds) - crosswinds etc

      • Teams can get penalized for driving fast through strong winds

      • Good to set up telemetry to see these impacts in real time

    • Dan’s team would try to run the same circuit with different gaps, speeds, etc to test the motor’s efficiency and other tradeoffs in a constant road environment

    • Consider the most efficient speed - not always the best speed at the same time, it may be too low to be competitive for instance

  • Understand what your array can produce in varying weather conditions

    • Getting current into battery can also have problems - ex he gives is that battery may have a hard time getting energy from solar at 90% since it’s more difficult to charge then

  • As we are a cruiser class/MOV, our weight is very important

    • The array will be adding energy, however likely will never get an energy in = energy out as the Challengers do

    • Elevations and motor torque profile are very important

    • You may have power, but pushing speeds that you can’t maintain is hard

    • Consider penalty of charging - hard to model, but suboptimal situations will always occur

      • There is a strategic value and you need to be able to take in this kind of charge effectively without losing back

    • The most important part though is how the battery affects how you tackle terrain and elevations with your heavy weight and extra passengers

  • Better to have the chase car to act as a HQ for strategy than the solar car, have a very good real time sync 👀

    • Not mentioned, but this seems to be a call out for better very good and reliable networking/telemetry

  • Dan has heard of teams using MathWorks (MATLAB) to do simulations and vehicle modelling

  • Clearly the takeaway through this Q&A is test test test!!!
