How we scored them
The Solar Score weighs performance, build, value, safety and warranty. For an extension cable, safety means the IP code and certifications the listing actually states; a cable that states no IP code scores lower on that line. None of the five state a warranty term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| iGreely 10ft Extension Cable | 9.7 | 32 | 22 | 21 | 8 | 0 |
| Renogy 5ft Extension Cable | 9.6 | 28 | 21 | 21 | 7 | 0 |
| QILUCKY 3ft Extension Cable | 9.5 | 27 | 20 | 21 | 7 | 0 |
| JXMXRPV 6.6ft Extension Cable | 9.5 | 26 | 20 | 21 | 4 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
