I've done it for small scale off grid telecom projects in the 10 to 20kW class of total quantity of panels at one site, not actually at my home (which is surrounded by trees on all sides in the pacific northwest, I'd need to build a 40kW ground mount to have any reasonable amount of production). It's completely doable if you study electrical fundamentals but I'd also recommend hiring a pro to help out if you don't have the background. 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.
