That's exactly what I am doing also, trying to size my system as efficiently 
as possible before I actually get the system

That's where I am right now. Also there is an advantage here cause this way 
there is no restriction on whether you are using an alcaline electrolyser or 
a PEM one. Also if you assume that you have the electrolyser coupled on a 
DC-DC converter (I am working with a DC electrolyser) the effciency then 
doesn't flunctuate so much from the given efficiency as a parameter.
