## Customer Reviews

### ⭐⭐⭐⭐⭐ You need this if your adding a second (third, fourth etc) solar panel to your setup.
*by F***E on September 1, 2020*

Easy to install and does what you need. I installed a second 100 watt solar panel and using this cable kept the panels in parallel which in turn kept my voltage at a nominal 12 VDC output. If you wire the two solar panels in series instead of using this cable, you would end up with a nominal 24 VDC system. That sucks if your charging a 12 volt battery, or your charge controller expects 12 volts.

### ⭐⭐⭐⭐⭐ Good product and I would suggest to other buyers.
*by T***T on December 1, 2018*

These worked out great. Because the ends split, it makes connecting multiple solar panels easy. I learned the hard way because the first set I bought were solid (plastic) and you couldn't connect multiple panels because the plastic connectors were too thick to fit next to each other when trying to connect. I would definitely get these again, and would suggest anyone setting up a system to do the same thing, instead of getting the fixed solid ones.

### ⭐⭐⭐⭐ Nice connectors if you need them
*by L***P on May 14, 2015*

Got these to connect two 100 watt panels on RV in parallel. Due to the 25' 10 AWG wire run from the panels to the controller I decided to run them in series instead to increase volts which decreases amps and resistance, hence increased system efficiency. Only down side to running series is you need a MTTP controller, which I believe is worth the extra cost due it's increased potential gain, and if one panel gets shaded this becomes the controlling factor in the system performance. With only two panels close to one another I wasn't concerned. Nice connectors if you need them.
