PV are generally rated by several criteria((http://www.kg4cyx.net/solar-panel-specifications-explained/)) | PV are generally rated by several criteria((http://www.kg4cyx.net/solar-panel-specifications-explained/)) |
* **Power (W)**: 190 Watts. <- rated power in Watts under lab conditions. You can derive **price-per-watt** by dividing $/watts. | * **Power (W, or Pmax)**: 190 Watts. <- rated power in Watts under lab conditions. You can derive **price-per-watt** by dividing $/watts. |
* **Open Circuit Voltage (Voc)**: 36.00 Voc <- Volts in full sun with no load. In practice you will likely not see Voc when hooked to the controller, but **all parts of your solar installation need to be able to cope with the theoretical Voc**. In serial arrays the Voc ratings are added. | * **Open Circuit Voltage (Voc)**: 36.00 Voc <- Volts in full sun with no load.

Also theoretical, but **connectors and cables need to be sized to handle Isc**. | * **Short Circuit Current (Isc)**: 7.42 Isc <- Amps in full sun when shorted.
