Solar panel giaride 18v 12v 100w high efficiency monocrystalline solar cell flexible bendable off grid solar panel charger for 12 volt battery rv boat car motorcycle camping.
Gluing solar panels to roof.
The panels put out too much voltage if the sun is strong and also when the battery is fully charged and does not need any more.
All solar panels need a regulator also called a controller.
That s a simple explanation.
Your caravan roof is likely to be made out of fibreglass with a gel coat finish.
Will the sika be strong enough by itself to hold the panel and mount in place or will i need to physically mount the panels by drilling through the van roof and securing with bolts.
The panel is screw attached to plastic biard mounting panels and i was aiming to glue this down onto the metal roof of my van.
3 4 out of 5 stars 121.
This unit takes the wires from the solar panel and controls the power to be good for the battery and not over charge it.
The panels can be securely attached to a shingled roof via an adhesive backing that anchors the panels even in winds up to 110 miles per hour.
Any help gratefully appreciated.
