Integrated performance optimizer available?
You can choose from all available module-integrated performance optimizers from the performance optimizer database (see Databases > Components > Power optimizers).
Selection of the arrangement of the cell strands
Here you define the dimensions and weight of the PV module. This information is required for module occupancy in 3D planning (see Pages > 3D-design).
The electrical characteristics of the PV module depend above all on temperature and irradiation. This results in a separate current/voltage characteristic curve for each module temperature and irradiation. In the range V/C Characteristic values at STC only characteristic values according to standard test conditions (STC) are entered.
All required characteristic values can be found on the data sheet of the corresponding PV module.
Here you define characteristic values of the PV module with lower irradiation. Since standard test conditions (STC) are not permanently available, the characteristic values at lower irradiation are important data for an exact simulation of the PV system.
To enter the partial load characteristic values, first select a partial load model:
Normally the PV*SOL®-own partial load model is used, which achieves very good accuracy for most module technologies. The model is used as standard for all technologies except those based on mono- and polycrystalline silicon. The PV*SOL® model calculates rather too low tensions at low irradiations and estimates the energy yield very conservatively.
For mono- and polycrystalline silicon-based modules, the two-diode model is used if all the necessary conditions are met. For these module types, the two-diode model provides the most accurate results for the electrical quantities. The deviations between the two-diode model and the measurement are in the range of measurement uncertainty.
The conditions for using the two diode model are as follows:
For further information on the characteristic models used, see Calculation > PV modules > Characteristic curve models.
Here you define further important characteristics of the PV module.
Maximum system voltage
This value indicates the maximum system voltage must not be exceeded for safety reasons. This mainly affects the series connection of PV modules.
The bifacial factor indicates the proportion of backside irradiation that a module can process to generate electricity. For conventional monofacial modules, this value is 0 because the back is inactive. With bifacial modules, the value is usually between 70 and 80%.
The resulting PV module characteristics are displayed here. You can choose from:
