Question:

I have 2 L track rails running down the top of my truck cap 60.5inch apart center to center and 93inch long. I plan to fill the top with solar panels. I will have to find and/or make brackets. Can I drill into frames or do I have to clamp? If clamping, do you have mounts for your panels? Im thinking your 195 watt panels are a good fit

Hello Blair, thanks for reaching out. You will have to drill into the top of your truck cap in order to mount solar panels. We do not offer any kind of clamp-on mount for a solar panel, so some drilling will be required. We offer a mounting hardware kit for the Go Power solar panels, part # 34272708. This comes with Z-style brackets with self tapping screws, and the nuts and bolts for attaching the panels to the bracket. You will want to use some butyl tape or self-leveling sealant to seal the holes.

I see that you were looking at the # e99FV solar kit which is a great choice for a full solar kit. This kit comes with similar brackets for the panels as well as the necessary hardware.

Hey Blair, how did things go with mounting the solar panels on your truck cap? Did the hardware kit and sealant give you a solid, leak-free setup? Your update could make it easier for others planning a similar solar build.

@JesseM I ended up mounting the panels directly to the angle aluminum with enough extra length to bolt the angle AL to the L-tracks. Worked great! I was even able to shift the panels to make room other L-track accessories by simply loosening the angle AL bolts and sliding it down the track a bit.

@BlairA Thanks for the update, that’s a great setup. Mounting the panels to angle aluminum and tying that into the L-tracks is a smart way to keep things flexible. Glad to hear it worked out well, and I appreciate you sharing the details. That’ll definitely help others planning a similar solar install.
