Even I can answer this one.
That 103 watt solar panel won't do you much good if you find yourself a few miles from the dock and no juice in your battery bank.
The panel is for producing power while the battery is for storing and delivering power. The battery is to an electric motor what carbon based fuel is to an ICE.
BTW, I'm a big believer in solar panels. To me they are like wind in my sails.

A 130 watt solar panel will give you about 500 watt-hours per day i.e. annual daily average. That's about 15 KWH per month. If you have a two KWH battery bank and double its' capacity you will have a four KWH bank. Adding another 130 watt panel will increase your monthly output to 30 KWH. Clearly adding solar panels is far more effective than increasing the size of your battery bank. So why is there so much obsession with batteries when the real power comes from the panels. Thanks.
