-  * **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.  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.

 While NOCT may be useful for gauging normal harvests, STC is used for system component((like controllers)) sizing because the panels really can make STC power((or even more)) in some real world conditions.  The system needs to be sized to deal with high-output situations, particularly overly high panel voltages.  While NOCT may be useful for gauging normal harvests, STC is used for system component((like controllers)) sizing because the panels really can make STC power((or even more)) in some real world conditions.  The system needs to be sized to deal with high-output situations, particularly overly high panel voltages.
