Dear Swonno, First and foremost, you must ensure that the surface area matches between the system definition and the 3D scene. What is your objective? Is the PV area defined in the system the actual PV area, or is it the one you defined in the 3D scene? You must adjust one of them to ensure they match. You can also use the 'Orientation Management' tool in the 3D scene. This tool helps you understand the extent and direction of the orientation. Regards, Muhammed Sarikaya

Dear Vera, The albedo you have modified surrounds the entire PV plant. For a bifacial system, you have the option to define the ground albedo beneath the PV modules. I invite you to watch our tutorial on bifacial modules on YouTube, where you will find how to set this ground albedo factor. Here the link: Regards, Muhammed Sarikaya

Dear Ranjit, First, click here in the higlighted in orange: Then you will have 2 subarrays. In the first subarray, enter "Nb. of inverters": 6, then in "Mod. in series" enter: 22, and in "Nb. strings" calculate: 6 (inverters) * 21 (strings) * 25 (SCB) = 3150. After that, in the second subarray, enter "Nb. of inverters": 2, then in "Mod. in series" enter: 22, and in "Nb. strings" calculate: 6 (inverters) * 20 (strings) * 25 (SCB) = 3000. We don't define the SCB in PVsyst. If you follow these steps, you will be able to simulate your project. Regards, Muhammed Sarikaya

Dear Ranjit, If your connection is consistent between each string, there's no need to mention the SCB. However, if there are differences between strings, you should specify this using sub-array and MPPT features. Can you tell me what your string configuration is? Regards, Muhammed Sarikaya

Dear Ranjit, Can you tell me where in PVsyst you are blocked so I can help you? Otherwise, I invite you to watch our tutorial to understand how to create a project in PVsyst. You didn't mention the inverter brand or the PV module brand you want to use. Regards, Muhammed Sarikaya

Dear Swonno, "If you have already entered a value in the 'Distance X1->X2' box, do not enter a value in the 'Image base width' box; you should define one or the other, not both. After you have chosen X1 and X2, you can notice the values defined for Y1 and Y2. Simply copy the value from Y1 to Y2. Regards, Muhammed Sarikaya

Dear Qasem, I invite you to read our help page about the Pnom ratio: https://www.pvsyst.com/help/index.html?pnomratio.htm Regards, Muhammed Sarikaya

Dear Swonno, When you take a screenshot of a Google satellite image, you must include the scale, which is in the right corner. You can read the distance on this scale, as shown in my example below: You can see that my scale is 5 meters. This is how you determine the distance between x1 and x2. Regards, Muhammed Sarikaya

Dear Mohamed, I invite you to watch this tutorial to solve your issues. Please let me know if you succeed. Regards, Muhammed Sarikaya

Hi John, I will show you a simple example of how to use the multiple MPPT feature. Let's say you have an inverter with 2 MPPT entries and you want to define each of them. First, you need to create two sub-arrays as below. When you select the first subarray, all the parameters you define are independent of the second subarray. This means that you have to select the second inverter to set all the parameters independently. To begin, the first subarray defines one MPPT entry of your inverter. Be careful, the box labeled "Nb of MPPT inputs" should be set to 1, meaning you are configuring only one MPPT entry of the inverter. You decide to configure 15 modules in series and 1 string. See below: Then, you select the second sub-array and you have to enter "1" in the box "Nb of MPPT inputs" to define only one MPPT entry of the inverter. Also, because its entry is different from the first subarray, we decided to define 18 modules in series and 1 string. See below: Next, you need to set up "Power Sharing." Click on the "Power Sharing" button. Follow these steps to set it up, see below: You have to move the sub-array from the right to the left under the inverter. I hope this helps you understand how to use the multi-MPPT feature and power sharing. Regards, Muhammed Sarikaya

Dear Swonno, I believe you are referring to the tool 'List and Management of Objects,' which is available only in the 3D scene. You can also access it through 'Tools > List and Management of Objects.' See below: Regards, Muhammed Sarikaya

Dear Shiwankar, It's not possible to import from Helioscope to PVsyst, and we are not planning to do so. Regards,

Dear Swonno, Unfortunately, this is the weakness of the table zone. It's an iterative process; you need to come back and check the number of PV modules and delete them to reach the desired number. Regards, Muhammed Sarikaya

Dear Meurville, It's not possible to avoid. Near shading will be calculated for the entire year. Regards,

Dear RCA, You can use the multi-MPPT feature and sub-array to configure your project. I invite you to read this help page: https://www.pvsyst.com/help/multi-mppt_more-examples.htm Regards,

Dear Polasek, I can't say anything at the moment. Could you please send us the project at support@pvsyst.com? I need to investigate and understand why you are experiencing these issues. Regards, Muhammed Sarikaya

Dear Dane Archer, In PVsyst, we provide a tool for calculating wiring resistance to estimate approximate ohmic losses. However, there is another way to calculate the total resistivity of your wire on your own. Then, you can enter this result in the following field: Regards, Muhammed Sarikaya

Dear Nayah, It's impossible for me to judge and determine why you have this difference. Can you please share your project with us at support@pvsyst.com, mentioning the issue you encountered? Regards, Muhammed Sarikaya

Dear Swonno, Look at this picture and set the highlighted Z value to 0. Regards, Muhammed Sarikaya

Dear Swonno, I already shared an example. It's important to select X1 and X2 on the scale. Regards, Muhammed Sarikaya

Dear Swonno, You missed selecting X1 and X2, which is why you are having trouble adjusting your image. When you import a ground image, it must include the scale. See my example: Be sure to have the same value for Y1 and Y2. Also, don't forget to set the distance between X1 and X2 to match the screenshot of your Google Maps. When you click, the size of your image will be adjusted. Additionally, you can modify the opacity, but don't click on apply. You must add a 2D image in PVsyst. Regards, Muhammed Sarikaya

Dear Zainol, You can modify the baseline slope. In the near shading window, click on 'Tools' and then on 'List and Management of Objects.' A new window will appear. In the 'Baseline Slope' column, set everything to 0. This way, you will have the same nominal azimuth and tilt that you defined initially. Regards,

Dear Swonno, Your first question is not clear. Can you explain what you are trying to do? Regarding your second question, by default, the ground object doesn't cause shading, but it is possible to activate it. You need to double-click on your terrain in the right panel and then check the "Enable shadow casting" box, as shown in the example below. Regards, Muhammed Sarikaya

Dear Vera, This information is a leftover from the first version of PVsyst. You won't find it in the technical datasheet. Please ignore it. Regards, Muhammed Sarikaya

Dear, I invite you to consulte this help page of PVsyst: https://www.pvsyst.com/help/shadings_factor_table.htm During the elaboration of the shading table, the points (sun positions) located behind the plane of the PV field appear in blue. The highest entry among the blue ones is extrapolated from the above entries. This is to avoid artifacts in the interpolation of the shading factors. Other entries for which the sun arrives behind the plane are marked as "Behind". Regards, Muhammed Sarikaya
