The 130W Kyocera's I was looking at are almost 2 feet longer (59" x 26") but a bit thicker (1.8") and definitely heavier (29#). The additional thickness is only in the new models as they claim to have beefed up the frame.
Just found this site that compares prices per watt of solar panels:
http://www.ecobusinesslinks.com/solar_panels.htm
Thoughts about the site:
- Some pretty low prices there, but most require large quantities.
- The 60W Kaneka panels (Japanese) are very cheap but also heavy (32# per 60W panel) and high voltage (92V Open circuit) which won't work with some MPPT controllers. But they're amorphous Si which I understand to be very sturdy. http://sunelec.com/index.php?main_page=kaneka_gsa60
- "We prefer not to include any cheaper Chinese solar modules at this time due to quality and after-sale service concerns", hmmm ... guess that's why there's no LaVie.
Decisions, decisions. Luckily it'll be while before we're boondocking, so there's no rush. |
I don't think the added weight would be in the frame. The frame on these panels are truly
very strong. I can't see any reason to beef them up. It would just be added weight with little return.
I think that it may be in thicker glass. Tempered glass is extremely strong when it is thick enough. Try breaking a car window some time. It's hard to do even with a hammer.
If this tempered glass is too thin, it can break fairly easily. That's why I say that I wouldn't step on these thinks or drop tools on them.
