At present the battery is completely flat. Is it likely that leaving a
solar panel connected for a few weeks would restore the charge? The
solar panel would be placed inside the windscreen or rear window.


If the battery is completely flat it might well be scrap.

I probably intend to also connect a desulphator to the battery with the
solar panel.


What's that? A high voltage low current charge - say about 30 volts or so
- will sometimes get a flat battery back to some usefulness. But not if
it's been flat for some time.
