Jamaican Slang. Always changing, never ordinary! To keep current with Jamaican slang, you need a teenager. So that's what I did for this page. I asked about ten teenagers to brainstorm (no, I didn't actually say brainstorm) with their classmates to come up with the latest expressions.
Most solar panels are 12 volt so use the same equation to find out how many amps the panel makes. 80W = 12V * X Amps 80/12 = 6.67 amps A 50 Amp Hour battery takes 50 hours to charge at 1 amp, 25 hours to charge at 2 amps, and 50/X hours to charge at X amps, just like the discharge calculation above.50/6.67=7.5 hours.ow most CFLs are 120 volts AC and not 12 volts DC like the battery, so I assume you have an inverter to make 120V AC power from the battery. The inverter will not be 100% efficient so the lights will last a little less than the full 23 hours.
Report Abuse. 90 amp-hr x 12v = 1080 watt-hours. Charging at 45 watts, then, would take 1080/45 = 24 hrs. The battery won't take charge at full rate when it's almost full, and the 45-watt rating is in full sunshine, so it will take longer-probably about 3 days of dawn-to-dusk sunlight.That's why they call those 45-watt rigs trickle chargers.asically, the 45 watt array at 18 volts has an amp rating of 2.5 amps. In direct sunlight at full power, it would take the array 36 hours to pump 90 amp hours into your battery.
