The Joule is the SI unit of energy, work, and heat, defined as the energy expended when a force of 1 newton is applied over a distance of 1 meter. It is named after James Prescott Joule, who discovered the mechanical equivalent of heat. [1] In terms of SI base units, one joule corresponds to one kilogram - metre squared per second squared (1 J = 1 kg⋅m2⋅s−2). One joule is equal to the amount of work done when. . Overview of how scientists use the joule unit to measure work or energy.

Following the successful measurements of Voc and Isc, the internal resistance can be calculated using the expression: R = Voc/Isc. For the resistance of a PV module an average value can be assumed:. . At a very simple level, PV cells function by using solar energy to generate electron-hole pairs, which then separate and flow in the external circuit as current. Measuring or obtaining the open-circuit voltage (Voc), 3. . Caution: Photovoltaic system performance predictions calculated by PVWatts ® include many inherent assumptions and uncertainties and do not reflect variations between PV technologies nor site-specific characteristics except as represented by PVWatts ® inputs. As the voltage increases the current through the shunt resistance increases and output current decreases until the Voc is reached.
