Agree to Disagree
Are $20 solar car kits good enough for teaching?
Our position, and the 'cheaper to scale' counterpoint.
Our position
The very cheap solar car kits have panels so weak they only work in full direct summer sun. Kids on a spring afternoon get 'it does not work' as their takeaway. Spend $25-35 per kit for the mid-tier version - the panels are sized to run the motor in reasonable light. The budget cars are a bad first experience.

Weather-dependent budget tradeoff
Nuanced / mixedIf you can reliably schedule lessons on sunny days, cheap kits might work. The scheduling is rarely that flexible.
Why trust it: Weather-reality framing.
High-volume program cost advocates
Pushes backSome programs buy cheaper kits in volume and accept a higher failure rate. For a one-shot fair-style activity, plausible.
Why trust it: Volume-vs-quality tradeoff.
