- Well We went camping weekend after this install-Wow was I very pleasantly surprised!
- Our 1st outing with 'new' solar panel was 6 days out, ran generator total of less than1 hour. Normally we need to run generator at least an hour a day to recharge batteries to 3/4 (by stock led meter) or longer every other day. Which only brings them up to minimum
- 3 days at camp #1 basically no gen, good, our second stop, camp #2 for 2 days was after about 2 hours of driving so that was on top of solar. But still no gen. Camped 6th/ last night with power.
- though shade does hinder or bring to a stop output its not as critical as I had thought. (though it wont be powering any major usage)
- at a min of 0.6 amps batteries will charge, panel is enough to compensate for our eve. hours usage/lights cooking 3 hours of tv etc.
- Though tilting of the panels does increase output, at least in summer its really not necessary. Winter may see more need-where we actually use more power during day &daylight hours/ directness are less. time will tell. (but we did allow ourselves to turn on lights this trip, when wanted, where we usually don't to conserve battery)
- Panel does keep up with our usage and keeps batteries fully charged. Winter may be a different story but if we do need to run gen for charging it wont be as critical and be on top of what panel can provide.
- batteries are lil over 5years old. Though still good, their capacities are probably quite a good percentage less than what they were new.
- oh yes-our scotters battery took a dump-signals/horn starter woundt work. It has a kick start but driving wouldnt recharge enough or didnt drive it enough for the scotter to recharge it. Theres a load wire (not hooked up to anything yet) from the solar controller. Its 7 amp out put and controlled by the controller. The scotter battery is 7amp---I figured out 3rd day I could use it to charge battery in scotter! Worked great.
- yes my original thoughts after building mounts were correct-there's too many bolts...It'll be easy to redrill for a single tilt bolt. When I get roun2it. Though I installed mounts with putty tape in case i needed to remove and modify not knowing how they would work-maybe sooner. I do need to clean up putty and liberally caulk mounts. Also thinking may be a short piece of tubing on ends of panel to direct branches up over panel.
- We were more than happy with results. I'm pretty confidant come winter, except in really bad weather (dark/windy) this will meet our needs. Definitely adding another panel would allow us a bit more flexibility (read more usage of power) but now I'm thinking this is great.
But 1st I gotta mention, I finished the install late bout an hour before sundown, but were in a shadow line, so there was no sun on the panel . Meter read 0 amps from panel, battery @12.2volts. Oh well , guess Ill wait till tomorrow to test.
Next morning we were socked in with fog, I eagerly waited for the fog to burn off. Finally gave up, went out bout 10:00, opened camper -didn't bother to remove camper cover cause it was wet. I wanted to see if the controller showed any drain on the battery overnight. Its minimal self-usage-but just makin sure. I open the door, glance at the meter-says battery @12.9 volts. What the heck? next read output from solar, 0.4 amps! Camper is covered & its foggy and the panel is charging the battery! Wow! Ran in the hose -excitedly told Margaret-Ran back out un covered camper-up to 0.6 amps, 0.9. Got up on the roof -tilted panel toward sun, 1.6 amps, in the fog. As the sky brightened the output increased. It got to about 3.5 amps, I was able to turn on 3 lights and the battery still showed an increase. Only when I turned on the range fan did the battery volts slowly start to drop. This is a good sign. Means if the sky's bright in inclement weather, were in some shade, Ill still might get something out of the panel..Yes!
Well we did. Our 1st campsite with panel was of course not optimum for solar. We pulled in late in the eve-picked our site cause it was the nicest. Ran some lights, watched a movie, battery was @12.1v by the time we went to sleep. The panel next morning I pointed right at the rising sun, Thru trees. Oh well -was about at 1.5 amps tilted due to partial sunlight thru trees (0.6 not tilted)-but the battery's charging! and its a really nice campsite. It did get up to about 6 amps at noon. Again due to darn trees it never reached its max of 7.5 amps. But I'm tickled pink. I really didn't think Id get that much from the panel when In the forest. As the sun arced thru the trees, amps output varied due to shading. But at the end of the day the battery was fully charged.
I reset panel bout noon. Mainly because due panel facing right at morn sun by noon it was facing wrong way. That and I wanted to play with tilting mounts. Though still in tree shadow it was charging 0.7 to 4 amps most of the day, hitting 7amps for brief periods. I realized as winter nears and the sun drops in the horizon , if the truck is positioned front facing south the air conditioner will seriously shade the panel-even tilted. However I also realized after some thought I cant remember where we weren't parked front of truck facing northerly. I'm sure as time goes on tilting wont be happening-unless we really need it but the option is nice. Actually we spent 3 days at this location and never fired up generator except for about 15 mins to cook dinner second day.
Our next camp site in Grant Grove we were positioned better but the panel was in a shadow and never got above about 0.5 amps till 11:00 then 6.5 to 7.5 the rest of the day/ I position panel facing south and never moved. Again we didn't use gen except for 1/2 hr second day so Margaret could dry her hair. (My inverter is only 400 watts drier is 1200).
