Junction Box for Solar Laminate with Two leads on back

I bought 6 - 300 watt solar laminates from a construction project that was cancelled. Each laminate has two metal leads protruding from the back, but all the junction boxes I can find look ready to receive 3 or 4 of these leads. Can anyone direct me on how to connect these safely to a junction box and how to best cover, protect and secure them to a stand-alone 20 degree raised frame?

Thank you for your time and help!

    Do you know what voltage the laminates run at ?  Many are at 90VDc which is a deadly voltage.  So be careful.

    Thank you Mike, I do not - need to run up to storage and get that info, though I believe they are 24v. I am also looking at a roof mount system, anyone have any thoughts on an inexpensive rooftop setup for 6 panels?
