Rated 5.0 out of 5.0 by Omegaman 15 ' extension cable
Reading a review about extension cables is very helpful. I believe I'll purchase the proper connecters and upgrade the wire size. Will the MC4 connecters work with #4 wire ?

Rated 5.0 out of 5.0 by rr Exactly as indicated
Useful for those installations that require more length than whatever comes with the solar panel. Good quality MC4 fittings, and the gauge of wire is, refreshingly, large enough.

Rated 1.0 out of 5.0 by Displeased Misleading product Add
If you purchase a solar panel from Grape off the Internet and order their extension cable you will get only a single (1) wire not a cable as defined by Webster IE..."a group of wires, glass fibers, etc., covered in plastic or rubber and used to carry electricity or electrical signals".. This product add is very misleading if you can't physically see it first hand. Very displeased when I went to install 3 panels and discovered this was only a WIRE and not a cable. I will be returning return the 3 so called cables I purchased and use alternate means. $16 for 15 ft of #12 wire is way overpriced.
Also wire size in their cable is small if you plan to put the controller any distance

Get two (one each for + & -) of these, unless your setup allows the panel to be within 20 or 30 inches of the charge controller. I park the RV in shade but can still collect solar with the panel about 12 feet away.

Rated 4.0 out of 5.0 by offgrid Part of a larger purchase.
The description needs to be updated to indicate that you will need two of these. Otherwise very pleased.

Rated 4.0 out of 5.0 by VJones Definitely need an extension cord.
Found out that need 2 of these, the one is not enough. The cord connected to the solar panel is very short.

Rated 5.0 out of 5.0 by Frdmftr Excellent, but you need two
This is very good cable, but being inexperienced in such matters I thought it was dual-wire cable. It is only one cable, and solar panels require two. As it turned out, 15-ft was the exact length I needed, and it works fine.
