I removed some of my finished interior ceiling panels. This is a conversion van, so they ran 3/8 plywood between the side to side braces from front to back. I drilled the roof down thru the plywood and added bolts thru the hinges on four corners. On the center hinges I added wood lags that went thru the roof down thru the plywood. Using lots of silicone under each hinge and more as I added a bolt or lag.<br><br>I can now tilt my panel in either direction. I bolted the hinges to the side of the panel and then used wing nuts and lock washers. So far with lots of driving, none have come loose. I carry extra and check often just in case.<br><br>The panel is 245 watts, 8.1 amps and 35 volts. So far, by about ten in the morning in partial shade my batteries are full. But I don't have much running and am not in it at night to run lights and charge computer. One cold morning it was charging at 8.7 amps.<br><br>I have about 9 12v outlets, two usb outlets, a couple non led lights,12v fridge, water pump and some small computer fans. Will be adding a 12v tv/dvd next week. Also running a 750 watt modified sine wave inverter, which I ran 4 gauge wire to. It will be running a printer/copier and a magic bullet once in awhile.<br><br>I ran 6 guage wire from the roof, 4 gauge to the batteries, 8 guage to two blue sky fuse busses and have a 2 0 running from a continuous duty solonoid up front, off the altenator.<br><br>Took me two days to install, that includes completely rewiring everything in the back of the van and adding a fan behind the fridge and one behind the controller.<br><br>I think I should have enough power now for all my needs.
