Assuming you're in the US 48 states there should be plenty of companies that'll take your money for a factory sealed pallet load of panels. They come wrapped up from the factory, basically all they do is do the invoicing/billing to you, they buy them by the 40' or 45' container load and then load them onto trucks at a loading dock.
PV panel factory datasheets will clearly specify how many are on a pallet and how many pallets fit in a single container.
I am curious what the installation process is like. It seems like all the home solar companies I've dealt with want to sell you the whole kit (panels, inverter, etc.). If you've done this, I am curious how your experience was.
There is considerable overlap between the knowledge base for -48VDC telecom battery/DC bus/breaker/fuse panel and distribution systems and PV/off grid solar stuff, so using some of the same people who do on-grid rectifier-to-telecom-DC-power-system work was fairly straightforward for us.
