The idea of the Next Tek was to "mix" the PV power with utility power to 
operate the lighting loads of a commercial building. The inverter would 
be cheaper and the issues of anti-islanding and dedicated transformers 
are reduced.  

Many of the electronic ballasts can actually operate directly on high 
voltage DC BTW.  There was a system done this way in the mid 90s back 
east by Richard Perez (not of HomePower but NY) which was funded by NREL 
etc. Never saw the results however.  

Its probably one of those good solutions looking for a problem kinda 
things....
