**TL;DR - These things are //EXTREMELY// expensive for the capacity, however they do offer a lot of convenience.** For those with plenty of money who value ease and speed over capacity and run-time, an argument can be made for these if your power needs are small-to-medium and you are only taking short trips in your vehicle. | ===== TL;DR ===== |

* **voltage** - 22Voc is a common voltage limit, effectively limiting one to [[electrical:solar:panels#panel_voltage|12v nominal]] panels. | * **voltage** - 22Voc is a common voltage limit, effectively limiting one to [[electrical:solar:panels#panel_voltage|12v nominal]] panels. |
* **current** limit - 3A is a common input current limit on smaller, less-expensive units. With PWM controllers the max power harvestable will be 3A x [internal battery voltage], which can be as low as 9v. 9v x 3A 27w. MPPT controllers with the same limit might run the panels at 18v: 18v x 3A = 54w.((minus DC-DC conversion losses of ~5%)) | * **current** limit - 3A is a common input current limit on smaller, less-expensive units. |
