Just an update on the performance of the solar
panels (160 watts) on the trailer in actual use. This is meant as a rough guide for anyone contemplating adding solar to their trailer and is not sure of the size of panel required.
While camping at the Langley meet last weekend with the trailer parked in a sunny location I found I would use about 4% of the battery
capacity each night (240 amp/hour battery). (1% of this loss is from my "phantom" loads) The radio was on all night and I was using a few lights
(Superbright LED's) for a few hours. Battery
would be up to 100% by 11 am. It wasn't warm enough to use the fantastic fan.
While working on the trailer parked in my driveway yesterday (in full sun) I had the radio on, a few lights
on and put the fantastic fan on the highest setting. The battery
stayed at 100% Over the span of three hours. Based on the system performance so far I believe I could easily get enough re-charging capicity from a single 80 watt panel for single or double occupancy.
(today is rainy and solid overcast. At 7:30 pm the battery is sitting at 97%. The 5 LED's have been on since 11 am and the CD has been playing for the past 4 hours.
Will keep this post up-dated as my sister, her husband and two young girls will be taking the trailer for a "family of four" test. Using more running water, more lights
, DVD players,video games, etc.
