Hello , i was working on a new project , i need to import meteo data from PVGIS but i found the following error . could you please assist
-
mohamed abdelkader started following ohmic losses , Different string lengths , power fed into the grid in kW and 2 others
-
Hello , i was wondering if it is possibile to adjust string lengths . for example , on my project there are 62 panels that are connected to one inverter of 2 mppt . so i need to connect 32 under one mppt and the other 30 panels on the other mppt , how can i connect different quantity of panels on inverter mppt ? . as you can see in the photo attached , i had to increase number of panels to 64 so number of strings will be 4 strings and mod.in series are alaways 16 . please note that under each mppt we shall connect two strings

power fed into the grid in kW
mohamed abdelkader replied to mohamed abdelkader's topic in Simulations
Yes, i have already defined them . but the results shows the energy fed to the grid (kwh) i need power in kW after considering power losses -
Hello , i was wondering if the output report of PVsyst could indicate the power fed into grid in kW after considering all losses . Mainly the report indicate the AC by summing all AC inverters power . but in reality , there should be auxlilary losses , MV transformer losses , Cable losses . hence , the AC power shall be lower than AC power of inverters . this value is important for us as it shall be communicated to energy distributor . so is there a way on PVsyst to know exactly this value ?

Hello , i inserted into PVsyst an imported file .PVC from PVcase , in near shading i get these messages and in the main window of PVsyst i see this message Could you help me to resolve this issue ?

Energy produced Hourly and negative power values
mohamed abdelkader replied to mohamed abdelkader's topic in Simulations
Hello , Thanks for your kind reply . some cells are are read as general i have adjusted all of them to numbers but also the summation is different than the produced energy in the report . is there any way to send you the excel sheet ? -
I have finished a simulation , i found that the energy produced to injected to the grid is 4118645 kWh/year i am attaching the calculation report . i have extracted in excel sheet to know how much energy produced for each hour . when i summed the total values of kW for whole the year , i found that the energy injected to the grid is 5226724 which is different that the total value in the report ( uploaded a snap shot) . could you understand this difference ? . also why in some hours i find power produced in negative ?

Hello , i have inserted some Batteries on my project . During the project simulation i get energy produced is around 48 MWh , when i print the report i fiind it slightely higher 49.7 Mwh . i couldn't understand the reason

Bifacial Calculation with Fixed structure
mohamed abdelkader posted a topic in Shadings and tracking
Hello , i am trying to perform a calculation with a bifacial panels but they shall be mounted on a fixed structure . in order to enable bifacial calculation it requires to enable unlimited trackers which is not the case . so how can i consider bifacial calculation with a fixed structure system -
Hello , i am trying to calculate ohmic losses for high voltage line , we have utilized 2 cables of 240 , in the wire section it begins with 400 mm2 . how cam i resolve that issue ?

Hello , i am trying to simulate a project in which i have uitilized two different inverter sizes , how can i simulate it ?
