Since most of the energy for BD production is heating (right? -- I haven't calculated out kilojoules used for different uses), I would use solar thermal collectors instead of PV. Small PV array to run the pumps/mixer etc. Solar thermal collectors are 40 - 80% efficient, so the area will be much smaller, and the temperature range is pretty ideally suited for biodiesel. Of course, then you need thermal storage too, but that's cheaper than batteries.
