I am looking at buying a solar panel The Informaion is below.

I would like to keep two 12V battery's charged when I am not using my boat.

Would the panel below do the job .

Would I require a voltage regulator.

Can it be a basic 12V regulator or dos it have to be a special regulator for a solar panel.

Would the sola panel have to be isolated befor starting the engin which has a alternator,

Specification:

Model No.: SP20

Watts peaks: 20w

Short Circuit Current: (Isc) 1.21A

Open Circuit voltage: (Voc) 22.5V

Optimum Operating Current: (lmp)1.11A

Optimum power voltage: (Vmp) 18V

Dimension: 630x290x25mm

Weight: 3kg
