    Below is a list of parts that I used. I’m not recommending any supplier:
    • Solar panel. Select the panel power output suitable for your van. Have a look at https://www.campingandcaravanningclub.co.uk/helpandadvice/technicalhelp/power/solar-power/. I bought mine from Photonic Universe on Amazon as the panel came with 5m of cable.

    • 1 x two-cable entry gland unit
    • 8 x 35mm M10 stainless button head bolts, nuts, washers and lock-washers

    • 20mm convoluted conduit (Screwfix)
    • 20mm saddle clamps and/or pack of 19mm stick on tie down pads for zip ties (Screwfix)
    • Zip ties. I used 5mm x 20cm

    • In line blade fuse holders, one for each charging circuit (Halfords)
