they all do nowadays. assuming you can't move them and depending on your setup, an enphase microinverter per panel can help minimize the impact shaded panels.
You could use micro inverters like Enphase IQ7 (one per panel) - you would need to buy a trunk cable (AC side L/L/N/GND = 120/240V - two hot + neutral = ground). Keep in mind: the inverters only deliver power, when the grid is active. When the grid is down, the micro inverters shut off (to protect lineman from being hurt or killed). You also could use a grid- tie inverter from Outback (high quality, but more expensive). Either way - check for getting a permit, if you tie into the grid
I didn’t see anything like that in the manual but they are very well constructed panels. Installed mine and everything is fine.
People are asking this "dumb" question because HD screwed up the description - HD description says "Pallet with two 265W panels total". This is incorrect, it's 4 panels total.
Grape solar specification sheet says that they meet UL 1703 standard for their GS-P60-265-Fab2 PV panels. Underwriter Laboratory (UL) 1703 Standard deals (in part) with impact testing. A paper at http://rci-online.org/wp-content/uploads/2012-CTS-koontz.pdf provides an overview of some UL 1703 impact testing with a 2" diameter steel sphere that generates 5 foot pound of energy. This is reported as equivalent to a ~2" diameter free-falling ice sphere at 22 foot-pounds. The paper discusses some of the dynamics of testing. Furthermore, Underwriter Laboratory site at https://www.ul.com/inside-ul/solar-panels-testing/ provides a description of impact testing under UL label 1703: (1) "drop a two-inch solid steel sphere from a height of 51 inches onto the surface of the PV module" and ( 2) a second test - "placing a perfectly formed spherical chunk of ice into a pneumatic cannon and firing the calibrated ice ball at 10 to 13 critical locations on the PV module.
The specification sheet at http://www.grapesolar.com/docs/GS-P60-265-Fab2.pdf list the GS-P60-265-Fab2 panels as "UL1702" certified for solar panels - UL1702 is UL (united laboratories) standard for solar panels.
I just measured them, and they are approximately 38.5 inches Wide by 65 inches Long by 1.5 inches Thick. That is what I have.
I'm not sure about that, but as long as they are mounted securely and don't get damaged by wiping them off on a tree branch or something, it seems to me that it shouldn't matter where they are mounted as long as they don't get damaged as a result of that. That being said, I would call Grape in Oregon and ask to be sure. The Home Depot Help Desk can call them for you in person and let you talk with them (DURING NORMAL BUSINESS HOURS), that's what I did. I can tell you that my Cousin in Oregon put these panels on the roof of his 5th wheel RV (mounted securely) and travels all over without any issues. He says they work great.
Hi , there is a full installation manual , specification , and datasheet on the product page. https://www.homedepot.com/p/Grape-Solar-265-Watt-Polycrystalline-Solar-Panel-4-Pack-GS-P60-265x4/206365811?cm_mmc=Shopping%7CG%7CVF%7CD27E%7C27-31_CONTROL%7CNA%7CPLA%7c71700000033101431%7c58700003865771066%7c92700031085865450&gclid=CjwKCAiAx4fhBRB6EiwA3cV4Krn3SDf2p-PDtb65C0k0j9gekIUiQm7fV3Ph_JBn5HgQOY_81aEYxRoCzfoQAvD_BwE&gclsrc=aw.ds
Rigid and built pretty sturdy with aluminum frames.
