Question 1

If the battery of my Truck is deadth, may I recharge it with the 80W panel? more or less how long does it takes?

Accepted Answer

Dear my friend,Good day and thanks for your question, so far as I know, to preserve the life-span of your battery, it is suggested to always keep it topped off during daily use.  For our panel, the peak power is 80W, but on normal sunlight condition, you can get about 50W, (2.2-3.0A 18V) , for most lead-acid battery, its power goes up to 120W (12V60A) It takes about 3-4 hours to fully recharge the battery.

Question 2

V*a=w, right? so how does a 60w panel only put out 2.2a at 18v? wouldn't that make this a 39.6w panel?

Accepted Answer

Odds are the electronics can handle up to 3A nominally.  Solar panels have, while in full and maximum sunlight, output of around 20volts ... so there's the 60watts.  With solar panels it's always best to halve the wattage rating so you know what you'll get most of the time (angle to the sun, shade, positioning, dirt on the panel, lots of variables).  Then you can reliably size your solar panels to your power needs as well.

Question 3

Can I connect these solar panels to a Goal Zero brand Sherpa 50 or 100?

Accepted Answer

You would need a "BiX Car Cigarette Socket" that includes a converter adapter. After that, you'll need a Goal Zero 98043 Adapter Cable to connect it to the Yeti 400.You could potentially splice your own cable to make this work, but this is the quick and dirty way to hook it up.

Question 4

Are the PV cells laminated in glass or acrylic?

Accepted Answer

It looks to be the same as 5V20W where the cells are laminated in plastic which is more flexible than glass or acrylic. The plastic may be polyethylene, as it is semi-rigid and glued together with silicone sealant. The PV cells themselves are semi-rigid and are claimed to be bendable to 30 degrees angle without damage.
