Solar panels for home use with led lights

G’day all , I am currently renovating at home and one of many jobs is to provide lighting under the pergola (colorbond steel frame with polycarbonate sheeting)which measures 10.0 m wide and 6.0 long .
I’ve got 240v downlights in the eaves along the house and there great ,but a little bit dark toward the outside edge, where I would install maybe 7 x 12 volt lights (at 1.5m apart).
So my thoughts are trying to utilise two 64 watt solar panels I have at home with the batteries on the camper that sit there most of the year doing nothing.
Can anybody offer advise/recommend a led type spot light to use along the gutter end similar to the interior lights in caravans/some campers.
Eg wiring 10.0m + 5.0m to anderson plug to extension lead from camper battery , possibly set up to timer or sensor to come at dusk and switch off at dawn if batteries will keep up to it.
I have looked at Springers/12 volt shop & ebay but would like to hear from some one who has this type of light. Would they suit this application or would I need more of them??

Thanks in advance
