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.

On the "Presentation" page, you can export the simulation results using the "Time Series (CSV)" button. Select the desired meteorological data series, and the radiation data in kWh/m² and the outside temperature in °C will be output to a CSV file: On the "Results" page, you can display the same data series for different time intervals in a diagram using the diagram editor:
