    Hallo Philipp, vielen Dank für die Zusendung der Projektdatei. In den Simulationsergebnissen wird die theoretisch maximal mögliche Netzeinspeisung angezeigt (31.200 kWh/Jahr) und in der Wirtschaftlichkeit die tatsächliche (23.168 kWh/Jahr), abzüglich Moduldegradation, Standby-Verbrauch des Wechselrichters und Nichteinspeisung (Solarspitzengesetz). In der Wirtschaftlichkeit haben Sie 475 Stunden mit negativem Strompreis berücksichtigt. Die Unterschiede in der Netzeinspeisung sind auf die Stunden mit negativem Strompreis zurückzuführen, in welchen nicht eingespeist werden darf.

    Hallo Sinä, wir beziehen uns noch einmal auf deine Anfrage. Es können vZEV und LEG wie eine Mieterstromgemeinschaft abgebildet werden, solange nur eine einzige Erzeugungsanlage existiert. Du kannst zwar beliebig viele Verbraucher (mit unterschiedlichen Bezugstarifen) simulieren. Es ist jedoch im Moment noch nicht möglich, mehrere Erzeugungsanlagen (mit unterschiedlichen Einspeisetarifen) zu berücksichtigen.

    Hallo, vielen Dank für deine Anfrage. Die Wechselrichter SMA Sunny Tripower Smart Energy 10.0 und SMA STP 10.0 3SE40 sind identische Geräte, es handelt sich nur um eine andere Bezeichnung. STP steht für Sunny Tripower und SE steht für Smart Energy. Die beiden MPP-Tracker dieses Geräts haben unterschiedliche elektrische Eigenschaften. Der zweite MPP-Tracker kann doppelt so viel Leistung aufnehmen wie der erste. An den zweiten MPP-Tracker können zwei parallele Strings angeschlossen werden, an den ersten nur einer. Wir nehmen an, dass du Aiko-Module der Leistungsklasse 485 Wp (nicht 465 Wp) verwendest, denn die 465-Wp-Module haben niedrigere MPP- und Kurzschlussströme, hier käme es nicht zu dem von dir geschilderten Problem: Der maximale MPP-Eingangsstrom des Wechselrichters beträgt 12,5 A am MPPT 1, das Modul hat jedoch einen MPP-Strom von 14,15 A. Deshalb gibt die Software eine Warnmeldung aus. Unter "Optionen" --> "Verschaltungsgrenzen" kannst du sehen, welche Toleranzbereiche eingestellt sind. Der MPP-Strom von 14,15 A überschreitet den 10-prozentigen Toleranzbereich. Wenn du hier 15 % Überschreitung erlaubst, verschwindet die Warnmeldung: Ein zu hoher MPP-Strom führt im Betrieb nicht zur Abschaltung des Wechselrichters, es kommt aber zu Abregelungsverlusten, die du dir in der Energiebilanz ansehen kannst:

    Hallo Philipp, vielen Dank für deine Anfrage. Die Einspeisevergütung in der Tabelle oder Grafik ändert sich in jedem Jahr, auch wenn du keine Degradation eingegeben hast, weil nicht der Betrag der Einspeisevergütung, sondern der Barwert angezeigt wird. Das heißt, die Einspeisevergütung jedes Jahres wird mit dem Kapitalzins (der Umlaufrendite) auf den Anfangszeitpunkt abgezinst. Falls du den Betrag der Einspeisevergütung unverzinst im zeitlichen Verlauf sehen willst, setzt du den Kapitalzins auf Null. Da die spezifische Einspeisevergütung (ct/kWh) auf Zehntel oder Hundertstel Cent genau eingegeben wird, geben wir auch die absolute Einspeisevergütung mit einer dritten Nachkommastelle aus.

    Hi Dave, Thank you for your inquiry. Our PV software cannot calculate costs. Component prices and other costs are not included. You must determine the costs of your planned system yourself. The calculated system price is entered into the profitability analysis and thus forms the basis for the financial forecast. The forms in the "financial analysis" module are pre-populated with sample values and do not represent average or empirical values. You must adjust these to suit your specific project. You can enter the detailed investment costs here:

    When using 3D models, please note the following: File size should be as small as possible, with a maximum of 250 MB. The maximum number of vertices is 500,000 (we recommend a maximum of 200,000 vertices to ensure optimal performance). Textures should not exceed 4096 x 4096 pixels. No perforated or open structures in the silhouette of the 3D model. The higher the complexity of the 3D model, the poorer the performance of PV*SOL, even if, for example, the maximum number of modules has not yet been reached. The following file formats are supported: For models in *.obj format, a *.mtl file and a *.jpeg file must be located in the same folder. Visual material properties (e.g. reflection, transparency, specular highlights, etc.) are defined in a separate material file with the file extension *.mtl (Material Template Library), whilst texture data is stored in separate texture files (e.g. *.jpeg files). The size of the *.jpeg file must not exceed 4096 x 4096 px. If your 3D model is too large, reduce its size using 3D modelling software before importing it into PV*SOL. In MeshLab, for example, this can be done via Filters → Remeshing, Simplification and Reconstruction → Simplification.

    For professional 3D modelling, we recommend the DJI Mavic 3E device. This drone is suitable for smaller and larger objects in normal lighting conditions. For large installations, we also recommend the Yuneec H600 with E45s camera. Smaller drones are only suitable for small objects and only in good lighting conditions and short shooting distances. The camera's CMOS image sensor should be at least 1' in size. The use of the flight pattern app Drone Harmony is recommended. A list of supported drones can be found here. Our partner solarklima e.K. offers expert training on handling the drone, creating 3D models and importing them into PV*SOL premium.

    You need consumption data for a calendar year. With 15-minute intervals, you need exactly 35,040 values. "Four values too many" indicates that four zeros were added to the file due to the spring time change. Delete these four rows: Then delete columns A, B, and D. You only need the raw consumption values, without timestamps or column headers, in the first column of the Excel file: The error message "No read permission" appears if the load profile is still open in Excel. You must first close the Excel program (or the file) before you can import the file. Importing a load profile is also explained in our help documentation.

    You can simulate your project using a generation load profile (e.g., from a hydroelectric power plant or a wind turbine) with certain limitations. Note that the generation profile must be lower than the consumption at all times. If the hydroelectric power plant generates and feeds more electricity into the system than is consumed, simulation is not possible. The overall profile must not be negative. You can also subtract the hydroelectric power plant's profile from your load profile beforehand in Excel and set the negative values to zero. This could look like this: To import the load profile, you only need the actual consumption values (only the values in one column), without time data or column headers. Importing a load profile is also explained in our help documentation. Limitations of the results: The total electricity consumption is not the actual consumption, but rather the consumption difference. The amount of electricity generated by the hydroelectric power plant that is not used to cover consumption is not calculated.

    If your climate data is available in hourly resolution (i.e., 8760 values each for temperature, global radiation, wind, and relative humidity), you can import it into our programs by saving it as an ASCII file, tab-separated, with the extension *.dat. The first lines (the file header) must look like this: Line 1: Location name "Vienna" Line 2: Latitude, longitude, altitude, time relative to Greenwich, -30 should remain. 48.11,-16.21,170,-1,-30 Decimal places for latitude and longitude must be entered in minutes, e.g., Vienna 48.1866° => input 48.11. For locations in eastern longitude, negative signs must be used when entering longitude and time. For latitude, a positive sign corresponds to the northern hemisphere. Line 3: Blank line Line 4: Must be copied as is; tab-separated Ta Gh FF RH Lines 5-8746: The following data lines are listed in the following order: outdoor temperature - global radiation on the horizontal plane/m² - wind speed - relative humidity; tab-separated. -5.0 0 1.8 75.5 -5.4 0 1.5 78.0 ... ... Please note that missing values must be filled with "0". Further information on importing your own climate data can be found in our help section.

    For inverter configuration, it is recommended to divide large systems into subsystems, for example, one subsystem per building, per building section, or per inverter. If you need to add or delete modules later, you only need to delete the inverter configuration for the relevant subsystem, not the entire system. To maintain the inverter numbering, we recommend using the "Define Module Areas for Configuration" function. Detailed instructions with screenshots can be found in this article. First, define which modules should be configured together. Select the desired modules of the first module area, right-click on the selected modules, and choose "Add to 'Define Module Areas' Dialog." Repeat this for all module areas belonging to the same inverter/subsystem. (To access a different building, use the drop-down menu in the top menu bar.) Then, click "Configure" and configure Inverter 1/Subsystem 1. Repeat these steps for each subsystem/inverter. Subsequently, subsystems 1 to x have a fixed inverter assignment 1 to x. The inverter numbering is transferred to the string diagram and remains unchanged even if minor subsequent modifications are made to one of the configurations.

    If you created your string layout manually or with other planning software and want to transfer this layout to PV*SOL premium for documentation purposes, the best way to do this is by using the "Define Module Areas for Configuration" function. First, define which modules should be configured together. Select the desired modules of the first string (for larger systems: the first MPP tracker or the first inverter), right-click on the selected modules, and choose "Add to 'Define Module Areas' dialog." Then, click the "Define Module Areas for Configuration" button. Rename the module area to "String 1" (for larger systems: "MPPT 1" or "Inverter 1"), either using the button or by right-clicking and selecting "Rename." Repeat these steps for all other strings (or MPP trackers/inverters). For the last string, you can use the "Import all unconfigured modules" button: Then click "Configure" and select the inverter(s): The string plan will be generated according to your specifications. You define the direction, starting point, and course of the strings in the lower left corner:

    An existing system is to be retrofitted with a storage system. A PV-adjusted load profile with 15-minute values for a full year is available. To take the PV-adjusted load profile (consumption profile minus PV self-consumption) into account, you need to perform two simulations. You model the installed PV system (taking module degradation into account, depending on how long the system has been operating) and use a standard consumption profile stored in PV*SOL that best matches your consumption type. Estimate the annual electricity demand: For the simulation, select the 1-minute time step. In the results, check whether the value "Total consumption – covered by grid" matches the annual total of your measured load profile. If the deviation exceeds 10%, adjust the annual electricity demand in the consumption profile and run the simulation again: Next, export the self-consumption data in 15-minute intervals. In Excel, add the 15-minute intervals of the measured load profile and the simulated self-consumption. For storage system design, you can now import your total load profile into PV*SOL. Delete the previously selected default load profile. Further information on importing load profiles can be found in our help documentation.

    Using the example of a vent that shades two modules (with >1%): First, define a separate module area for the two shaded modules. Ensure that PV modules can be selected individually. Select both modules and right-click to choose "Add to 'Define Module Areas' dialog." Click "Define Module Areas for Configuration." In the "Define Module Areas" dialog: Rename the module area to "Roof Area South - shaded." Import all other modules and rename them to "Roof Area South - not shaded." Click "Configure." Next, in the inverter configuration window, select both module areas and choose "Configure module areas together": Now select the desired inverter, choose the polystring configuration (for one of the four MPP trackers), check the box for "Power optimizers," and assign the two module areas as follows: The two modules with optimizers are then correctly assigned in the string diagram:

    The module tilt and orientation are influenced by two factors: the tilt of the mounting system and the pitch of the roof. Together, these two tilts determine the resulting module tilt and orientation. This can be visualized as follows: If you were to place a ball on the module surface, it would not roll exactly in the direction of the mounting system due to the two tilts, but would instead roll in the direction of the roof pitch. This is the resulting module orientation. The steeper the roof pitch, the greater the deviation of the resulting module orientation from the orientation of the mounting system. For example, if you have a mounting system facing south on a west-facing roof, the ball will not roll south, but southwest.

    Hello Antonia, Thank you for your inquiry. The user license is not bound to one device. You can install PV*SOL on multiple devices and use it with the same sign-in details, but it is not permitted to use the program simultaneously on multiple devices. The Valentin License Portal is an online portal in which license managers can independently manage their company’s user licenses and assign them to license users. You can assign several license users to a license, but there can only be one active license user per license. You can find a detailed explanation in our help section.

    Scenario 1: You can connect all modules on two or more roof areas together using the "Configure all unconfigured modules" button: Scenario 2: To configure several—but not all—modules from the same roof area to a single inverter, first select them by holding down the Ctrl key and left-clicking. Then, right-click and select "Configure": Scenario 3: You can also configure multiple module areas on different roof areas together. First, define which modules should be configured together. Select the desired modules from the first module area, right-click on the selected modules, and choose "Add to 'Define Module Areas' Dialog." Use the gray arrow to switch to the other side of the same roof. (Or you can use the dropdown menu in the top menu bar to switch to a different building.) Now select the desired modules of the second module area, right-click on the selected modules, and choose "Add to 'Define Module Areas' dialog." Then click the "Define Module Areas for Configuration" button: You can rename the module areas if necessary (right-click → Rename). Then click "Configure": In the inverter configuration window, select both module areas and click "Configure module areas together." You can then select the desired inverter:
