I'd hardly call this a "Solar powered" vehicle. The single 225w panel on
there isn't going to contribute much range when he's maxing out that 1kW
hub motor. His pack is so small that he can't bank the extra range
when he's not driving, again, he'd probably be better off mounting the
panel on his house, then he can use the grid as his battery and charge the
car at night.
Also... He's using a simple boost converter to match the
PV to his pack... without MPPT, he's leaving a lot of wattage on the table.
These are all worthwhile areas for improvement, Phil. But we don't know
how he intended to use the vehicle. Maybe he doesn't have a home where
he can mount his PV panels. Maybe he has "just enough" PV to cover his
daily range. Maybe it's just an experiment, to see what works and what
doesn't.
It does illustrate what is probably the biggest problem with home-built
vehicles; the lack of knowledge and experience. My first EV (in the
1970's) was barely functional, because I knew so little and had no
sources of good information. In theory, it should be easier today; but
the internet has more bad information than good. Experimentation may
have been his only way to get accurate knowledge.
(Though I wouldn't want to be caught dead in it, which is likely with traffic
in India!)
Well, it's probably safer than a bicycle, or motorcycle, or tuk-tuk. :-)
