The tenant electricity model is unfortunately not selectable as a balancing/feed-in concept and must be entered/adjusted individually. Assuming that the demand profile represents the tenants' consumption, self-consumption corresponds to selling electricity to the tenants. This can be accounted for through savings by defining a from-grid tariff that corresponds to the selling price to the tenants. The electricity fed into the grid is compensated with a feed-in tariff or via direct marketing. Since the operator may also have to/be able to guarantee security of supply, the generated PV energy may not be sufficient to cover the tenants' demand. In this case, electricity must be purchased from the grid by the energy supplier. To account for this, you must multiply the amount of electricity purchased by the energy supplier's price per kWh and enter this value under "Other Costs" in the "Financial Analysis" under "Economic Parameters --> Cost Balance".

No, 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.

Dear Anders, Thank you for your message. We confirm that the result of the shading analysis is plausible. The trees are not very tall and the modules are not located directly at the roof edge. It should be taken into account that the trees could grow over the operating life of the PV system.

Dear CarlSEL, Thank you for your inquiry. We confirm that the manufacturer Sungrow has listed the SG150CX inverter with a maximum input voltage of 1100 V in our database: According to the datasheet, the open-circuit voltage of the DM510M10RT-B60HSW/HBB/HBW/HBT/HST module under STC conditions (25 °C) is 45.1 V. The maximum open-circuit voltage is calculated for -10 °C. The temperature coefficient of the voltage is -0.247%/K or -111.5 mV/K. The temperature difference from +25 °C to -10 °C is 35 Kelvin. This temperature difference leads to a voltage increase of 35 K * 0.1115 V/K = 3.90 V. This results in a maximum open-circuit voltage of 45.1 V + 35 K * 0.1115 V/K = 49.0 V per module. String with 21 modules: 1029.05 V String with 22 modules: 1078.06 V String with 23 modules: 1127.06 V String with 24 modules: 1176.06 V PV*SOL allows the connection of 21 modules (normal range) or 22 modules (MPP voltage tolerance range of 865.7 V, normal open-circuit voltage range of 1078.1 V). We cannot reproduce your configuration with 24 modules. Please send us a screenshot or the project file (*.pvprj) to hotline@valentin-software.com, and we'll take a look at it.

When simulating different modules that have the same power output and similar characteristics, yield differences are usually due to the low-light performance. Module manufacturers enter their own data into the PV*SOL database. They have the option to define a specific low-light performance for the module. A specific low-light characteristic curve is then calculated for the module. If a manufacturer does not do this, a standard low-light performance for the respective module type, e.g., monocrystalline, must be assumed. The low-light performance used for the selected modules can be found in the database. Example module (600 Wp) with specific low-light performance Example module (600 Wp) with standard low-light performance

Losses during charging/discharging The efficiency curve of the battery system determines the losses that occur during the conversion of electrical to chemical energy and vice versa: Battery losses The battery's internal resistance and self-discharge rate determine the losses that arise from aging processes:
-
The reduced feed-in power can be entered in relative (in %) and absolute (in kW) terms. If you enter an absolute amount for several inverters of different sizes, this is converted by the software into a relative amount and distributed accordingly to all inverters. Small inverters are still penalised compared to large inverters because the small inverters are curtailed first when very small quantities are curtailed.

How can I use my own company logo in the project report?
hotline_oh posted a question in FAQ (Read only)
You can import your logo under "Options" → "User". Supported file formats are *.gif, *.bmp, *.png, and *.jpg. However, T*SOL only supports logos in bitmap format (*.bmp).

The download of the new software release stops during the automatic update process. I got the message "The operation timed out" or "the time limit is reached". What can I do? The program needs a relative constant and stable internet connection. If this is not guaranteed, then the program aborts the download of data. Alternatively you can also try to download the latest program version from the download section of our webpage: http://www.valentin-software.com/en/downloads/products Please execute the downloaded setup file. The old program version doesn't need to be uninstalled.

Is PV*SOL also compatible with Mac computers (Apple)?
hotline_oh posted a question in FAQ (Read only)
The PV*SOL software is written for Windows systems only. It cannot be used directly on a Mac. You can use a virtual machine like Parallels or VMware on your Mac. You can install Windows and run PV*SOL within it. This works without problems for many of our customers. We do not test the use of PV*SOL on a Windows VM on a Mac and therefore do not offer official support for this. -

At startup, we check the accuracy of the system time (the time displayed by Windows). To do this, we compare the system time (time zone adjusted, i.e., UTC) with the UTC time from the time servers of Microsoft, Apple, or Google (depending on availability). If this difference exceeds three minutes, a dialog box will appear. Please ensure you are using the same time server. Check under Settings --> Time & Language --> Date & Time --> Additional settings to see which time server is configured and synchronize it if necessary.

Reactivation of software If you want to move your license to another computer, you must first release the relevant serial number on the old computer. To do this, please open the program on the old computer and carry out the following steps: Help -> Registration -> Change registration -> Release serial number With the released serial number you can register your software on the new computer. Important: You can only release a license yourself once in six months. If the release did not work or you no longer have access to the old computer (e.g. after a hard disk crash or an update of the operating system), we can release the license for you or give you permission to early deregistration. Please uninstall the software on the old computer (if still possible) and send us the "Software reactivation request" form, completed and signed, by e-mail. Processing takes about a working day. The data collected in the form will be processed for the purpose of responding to your enquiry in accordance with legal regulations. For more details, please see our Privacy Policy.

Dear Anders, Thank you for your inquiry. To check if there are any shadowing objects that you want to include in the simulation, it's best to use the Google Solar API to display the orthophoto of the area. Horsens (trees in the northwest are shading the roof): Hjørring (no significant shading objects): More information on using the Google Solar API elevation data can be found in our help section.

Dear Anders, Thank you for your inquiry. This error message appears if you are in the wrong view (e.g., terrain view). Activate the building (right-click on it --> Activate) or select it from the drop-down menu in the top menu bar. Then you can add more objects to the roof using the polygon tool. You can extrude buildings and 3D objects and define a height for them. This allows you to include the shadows of these objects in the simulation.

Dear dvd, Thank you for your inquiry. When planning with the Google Solar API or with a map section from another map provider, you are unfortunately limited to a size of 200 m x 200 m. The area cannot be enlarged. We will forward you request to our development team.
-
Dear Anders, Thank you for your inquiry. The quickest way is to place a barred area over the courtyard: Alternatively, you can draw a polygon with ten vertices and extrude an arbitrary building. Note that the roof surface is interrupted at one point on the north side. Modules cannot be placed over this line: Both project files are attached.
