I was thinking about a smallish heated propagator. Are there any such

It's a difficult question, isn't it? The amount of electricity they use

True but to get that amount of power from a photovoltaic panel will need a
rather large one which uses a lot expensive, in energy terms, silicon.

Why the 'but'? I think we're in agreement ;-)
