Hi,
You might want to upgrade with a pair of 140 watt panels. They are $229 at this place. SunElec.com
You can make brackets out of 2" angle aluminum 6" long and drill holes into one side and 5/16" for the bracket to the panel.
You can buy a 20 amp PWM controller for about $20.
The more expensive MPPT controller used to be cost effective, but it is less expensive to buy another panel than to get a little more power from the MPPT controller.
Good luck,
Fred.
