Solar Cell Powered Battery Charger 12 VDC 15 Watts
How long would it take to charge a 230 CCA tractor battery with this solar panel?
The charge time depends on several factors. For example, if the battery was badly discharged (worst case), you had a cloudless day with lots of sun (best case), and you could keep the solar cell oriented at the sun (best case), it would take about 8-hours to charge the battery. Obviously, if you had a battery only slightly discharged it would take less time under the best conditions. On the other hand, if you did not have good sunshine and orientation, it will require more time.

How long would this extend the life of a car battery.
The battery in question is a 2000ah with a 500 watt draw. The minimum Voltage is 10 volts starting voltage is 14
Solar panels will keep your car battery charged as long as sufficient time is given in the sunlight. I use solar power every where. Free NRG! I use these on my RV to keep aux batteries topped off. I also use them to charge smaller gel-cels which I use for portable music systems. They work great, lo-maintenaice, just wipe them off, keep them clean.America should be going solar-our semiconductor fabs should be pounding out SPs by the square mile and the price would come down. Right now about $1/watt.

Can be connected in parallel?
Hi.Since I have no data about the charging circuit of these panels, I'm wondering if they could be connected in parallel. I want to put it on a cabin and connect it to a battery (12v, 35 Ah). So, during the day it will charge, and at night power some LED lamps. Thanks in advance!
Yes these can be wired in parallel or series depending on the amount of voltage you need at the course.
