PV*SOL premium

Dynamic simulation pv program with 3D visualization and detailed shading analysis of roof-integrated or mounted grid-connected photovoltaic systems, with storage systems

Overview

A real-world representation of the shading from surrounding objects is extremely important for precisely calculating yields. You’re therefore looking for a program which takes shading into account as analytically as possible? PV*SOL® premium does just that! You can visualize all roof-integrated or mounted systems - even on the ground - with up to 5,000 modules in 3D and calculate shading on the basis of 3D objects.

The user-friendly 3D menu navigation is divided into the six sections of terrain view, object view, module coverage, module mounting, module configuration and cable plan. Simply select possible shading objects and position them on the terrain or the building. PV*SOL® premium then calculates how often on average the modules are shaded by the objects and displays the result in graphical form.

Your benefit: the visualization in 3D mode provides you with detailed information on shadows cast at various times of the day and year, and consequently on likely reductions in yield.

Through the detailed analysis of the shading of individual modules, the effect of power optimization on the system yield can also be precisely visualized in PV*SOL® premium.

All of the PV*SOL® features are also included in PV*SOL® premium.

Program Details

Design of Grid Connected Systems with Battery Storage

Plan your own battery storage system by quickly and easily selecting the batteries used and defining the battery inverter and charging strategy.Alternatively, you can load complete battery storage systems from leading manufacturers. Due to the reliable and validated simulation models, you can make even more precise statements about the self-consumption and self-sufficiency rates.

Simulation of Solar Power Plants of up to Two Megawatts in 3D mode

PV*SOL® premium enables users to plan and visualize roof-integrated, roof-top and free-standing plants with a power of up to two megawatts. The maximum number of solar modules that can be visualized in 3D mode has been increased to 5,000.

Modeling of PV Area and Vicinity – Terrain View

PV*SOL® premium leads you in a few easy steps to your target. First, you select one or more PV array buildings from a collection of common building types and sizes as required. Dormers, bay windows, walls, saw tooth roofs, and projecting roofs can also be covered with PV modules. It is possible to model the available roof area with millimeter precision by entering measurements for the roof overhang and restricted areas. You then simply enter the objects that could cause shade – buildings, trees walls, masts, etc. – and size them. Objects in the distance can be taken account of as a horizon line.

Restricted Areas and Shading Objects on the Roof – Building View

When the dimensioning of the PV array building is complete, in the next step you can position and scale restricted areas and other shading objects on the roof, such as windows, chimneys, dormers, fire walls, satellite dishes, etc.

Module Coverage

The coverage of a roof area with the maximum possible number of modules is carried out automatically or manually by selecting the coverable areas. Where required, PV*SOL® Expert can promptly display the annual reduction in irradiation (direct and diffuse radiation) for every point on the PV area and every module. In this way, you can make a more informed decision as to whether a module is viable or not at this position.

Optimizing Module Configuration

The configuration of the modules can be carried out automatically or manually. You can decide whether you want to configure multiple module areas with one inverter or choose an inverter for each module area - or combine both. The current status of the system check for the complete configuration, each inverter and MPP tracker is displayed at all times in the configuration window. This means that you always have an overview of ​​whether your chosen configuration is in the design, tolerance or restricted area. Another highlight is the option "Suggest Configuration", which allows you to quickly and easily load the best configuration from your favorite inverters into the design. After configuration, the assignment of modules to strings can be individually adjusted, for example if required by the shading situation.

Textures for 3D Objects

For a realistic image of the building, you are able to personalze all the 3D objects with your own textures.

Shade Animation

A wide range of animation tools are available to the user when working with the software, so that each shade scenario can be visualized at any point in time.

Simulation with Power Optimizers in 3D mode

PV*SOL® premium can also simulate the influence of any power optimizer chosen. Thanks to the detailed shading analysis down to the level of the module itself, PV*SOL® premium can now determine exactly, for each application, whether the use of a power optimizer is advisable and economical.

East-West Mounted Systems

PV*SOL® premium facilitates the simple and comfortable design of east/west mounted systems.

Interface to the programme k2base

PV*SOL® premium has now received an interface to the programme k2base for the design of mounting systems. Simply and comfortably, all of the information can be exported as XML files and processed directly for the assignment of as many roof surface areas as desired – for example, the dimensions and exact position of the modules. The additional costs for developing the roof-top view with the mounting system software have been omitted.

Photo Dimensioning with Photo Plan

The integrated photo dimensioning program Photo Plan is a tool to quickly and easily visualize your customer’s roof using a photo. With a reference dimension, the respective roof with the planned PV system can be presented photorealistically and all the necessary roof measurements taken. Photo Plan therefore provides real decision support!

Component Database

The extensive module and inverter database currently contains around 13,000 module and 3,100 inverter data sets that are continuously updated and extended by the automatic update function. The data is maintained online directly by the respective manufacturers. You can speed up the selection of components by adding lists of favorites.

Climate Data

The MeteoSyn climate database contains around 450 data sets from the German Weather Service for Germany with the averaging period 1981-2010, as well as over 8,000 global data sets, based on meteonorm 7.0 with the averaging period 1986-2005. You can easily select the climate data via an interactive map. You can also create new climate data either by interpolation from existing measured values or on the basis of your own monthly mean values.

Detailed Circuit Diagram

On the circuit diagram page, you can see a representation of your PV system with standardized circuit symbols, e.g. for registration with the energy provider. The circuit diagram can be exported in DXF format.

Dimensioning of all AC and DC cabling

To deliver genuine results, the program calculates both the string cable losses as well as the AC and DC cable losses per inverter. On the cables page, you can enter cable lengths and cross sections, and let the program calculate the resulting total loss from the array output (under STC conditions). In addition you can dimension the electrical protective devices and the DC topology via various distributors. During a pre-planning phase, you can enter the total loss (under STC conditions).

Yield Simulation

Auf Basis der eingegebenen Werte führt PV*SOL® premium eine Ertragssimulation durch. Diese beruht auf einem mathematischen Modell, das für jedes in der Datenbank enthaltene PV-Modul die exakte Nachbildung der Kennlinie ermöglicht. Damit können Sie auch die Erträge von Dünnschichtmodulen genau berechnen. Dabei wird der Einfluss von Bypassdioden und die stündliche Teilverschattung jedes Moduls berücksichtigt.

A yield simulation is now run in PV*SOL® premium's technical dialog, taking into account the influence of bypass diodes and the partial hourly shading of each module.

Financial Analysis

You can enter detailed costs for the modules, inverters, or mounting in PV*SOL® premium. Loans, discounts, depreciation, and tax payments, as well as the month that the system goes into operation, are all taken account of. Various feed-in tariffs and bands for systems on roofs, building facades, and ground-mounted systems can be saved and amended. PV*SOL® premium determines not just the capital value, but also the electricity production costs and the amortization period according to VDI Guideline 2067 (VDI: Association of German Engineers). The selection of multiple feed-in tariffs is possible, and their terms can be defined as follows: parallel, consecutive or offset. Deeming can be considered when designing systems with self-consumption in the UK.

The results are shown in a detailed table in the balance of costs.

Photovoltaics

We have again compared the simulation results from PV*SOL® with actual measured PV module data. For all PV modules, for which manufacturers provide details on the part-load performance of their PV modules,  the projected yields after simulation with PV*SOL® correspond very closely with the measured results of the PV modules, due to the precise efficiency curve.

If, however, the manufacturer has not provided details, so that for these PV modules the corresponding efficiency curve in PV*SOL® must be based on standard part-load performance data, the simulation results are considerably lower compared with the measured results, at least for crystalline PV modules.

In order to meet the current development trend for crystalline PV modules, in version 5.5 of PV*SOL Expert the standard part-load performance efficiency curve has been adjusted. Therefore the yield can increase up to approximately 3% in the latitude regions of 30° and 5% in the mid latitudes (50°).

This concerns the following crystalline cell types:

- Si monocrystalline
- Si polycrystalline
- EFG
- ribbon
- microcrystalline

Photovoltaics

The SolarEdge system includes module-level DC-DC power optimizers and string inverters.

PV*SOL does not perform system design for SolarEdge inverters and power optimizers. Please use the SolarEdge Site Designer for string sizing, inverter and power optimizer selection.

Then PV*SOL can be used for energy estimation of the design obtained from the SolarEdge Site Designer.

For a detailed description please see the following PDF.

The SolarEdge Power Optimizers are only available from the program version PV*SOL Expert 6.0.

Photovoltaics

When you try to generate a project report the following message appears: „DLL nicht gefunden“ or „DLL not found“.

Please download the missing dll file here , unzip it and copy the "Projektberichtdll.dll" file to your program directory. If you are using the default directory it should be as follows:

Windows XP:

C:\Programs\Valentin EnergieSoftware\PVSOL xxx\dll\

Windows Vista/ Windows 7

C:\Program Files\Valentin EnergieSoftware\PVSOL xxx\dll\

Photovoltaics

A horizon with an elevation angle of 2° all-round is entered as a shading object as a default in the program version up to PV*SOL Expert 5.5. This setting leads to a small yield reduction due to horizon shading. If you wish to delete the horizon object, please select the "Horizon" menu item in the terrain view and delete it by changing the elevation angle from 2.00° to 0°.

Photovoltaics

The net present value is displayed, and not the amount of the feed-in tariff. This means that the feed-in tariff every year is shown minus the capital interest calculated since the starting point. If you wish to see the course of the feed-in tariff over time without interest being taken into account, please set the annual average return on capital employed to zero.

Photovoltaics

In PV*SOL premium and PV*SOL the number of modules per sub-array is limited to 100,000. Within the 3D visualization you can plan with a module number of up to 5,000.

 

Photovoltaics

Your module does not have 100W, but only 98,5W. The output given by manufacturers is often rounded. The actual nominal output, as calculated in PV*SOL, results from the MPP current and MPP voltage under standard test conditions (STC).

Photovoltaics

This is not possible directly from PV*SOL. However, you can copy the table to the clipboard (button “Copy Table”) and then paste it into e.g. Word or Excel. You can then print the table from there.

Photovoltaics

If you want to determine the number of modules by using the roof dimensions you have to select the option "Determine Output from Roof Surface" in the "Technical Data" window. The button "Roof Parameters" beside this is then activated. Click the button to access the "Roof View" window.

Photovoltaics

The climate data are stored in a database. In PV*SOL Pro/Expert they can be viewed by using the menu item "Results" - "Energy and Climate Data". Select the desired data category, like "Radiation", "Wind" or "Temperature" and press the "OK" button. To view more detailed results you can scale the graph via the "Axes" - "X-Axis" menu. Choose your desired time and display interval. The graph can also be viewed in tabular format. To do this click on the "Table" button. The table can be exported for further processing, e.g. in Microsoft Excel.

In PV*SOL premium and PV*SOL the Excel export in the presentation window can be used to display hourly values of the climate data.

Photovoltaics

Yes. In the dialog "Technical Data" - "PV Array" you can select between single and dual axis tracking:

- With single axis tracking, an azimuth of -90° to 90° is taken into account, with a vertical rotation axis.

- Dual axis tracking calculates the situation with movement of both rotation axes.

In both cases, the technical limits of the tracking system are not taken into account. This means that if the tracking system can only be rotated up to a certain angle, this is not taken into consideration by the software.

To use this feature in PV*SOL Expert please select system planning without 3D visualisation.

Photovoltaics

The PV Solar Surface Area is the area that forms the basis of the manufacturer’s measurement of module efficiency. For simulation, the program determines the Solar Surface Area from the calculated power and efficiency (ETA), using the following formula:

PV Solar Surface Area = Nominal output(STC) / (1000 W/m² * ETA(STC)) 

In some cases, the resulting figure is different from the Gross PV Surface Area. If, for example, the manufacturer does not take the module frame into account when calculating the ETA (STC), in order to obtain a better ETA (STC), the Solar Surface Area will be smaller. For a Solar Surface Area that corresponds to the Gross PV Surface Area, you should click on the calculator symbol to calculate the Module Efficiency.

Photovoltaics

With PV*SOL you can build modules and inverters from different manufacturers into a system and mount these at different orientations and inclinations. To do this, the program splits the system into a number of different sub-arrays.
A PV array/sub-array is a PV surface unit made up of the same types of module mounted together and set at the same angle and orientation. If you have a number of inverters connected to an array, these also have to be all the same type and configured in the same way.
You are able to define up to 6 sub-arrays in PV*SOL Pro/Expert. In PV*SOL premium and PV*SOL the number of sub-arrays is arbitrary.

Photovoltaics

Yes, because the module array is simulated in terms of its installation type, azimuth and tilt angle of the modules and its height above the ground, independent of whether the modules are installed on a roof or on the ground. In the 2D planning you should select "Free-Standing" for the installation type. The height above ground can be defined in the "Losses" window. In the 3D visualization please select one of the open areas as coverable object.

Photovoltaics

The decisive factor for the yield is the part load efficiency. In this area, amorphous modules usually have a better efficiency than monocrystalline modules. The part load efficiency is presented in the efficiency characteristic curve which can be displayed under "Databases" - "PV Module" - "U/I Char. – Part Load" by clicking the "Efficiency Char. Curve" button.

Photovoltaics

No, with our PV programs it is not possible to calculate costs. There are no component prices or other costs included in the software. Every user will need to find out the costs for the planned system themselves. The system price determined by the user has to be entered in the "economic efficiency calculation" dialog and forms the basis of the economic efficiency prognosis. Default values are provided in the economic efficiency calculation and should not be viewed as average or empirical values. They need to be adjusted by the planner.

Photovoltaics

Whether the system is roof-integrated or roof-parallel does not play a decisive role in visual planning in the 3D tool, and thus the 3D tool does not yet differentiate between the two. Categorisation of the system as being roof-integrated or roof-parallel only occurs after 3D planning has been completed and you have returned to PV*SOL in the dialog "Losses" under Installation Type. Please select the option " With Ventilation" if your system is installed on a substructure parallel to the roof cladding or "Without Ventilation" if the system is integrated into the roof cladding. The calculation then takes the corresponding temperature situation into account. You can access the dialog "Losses" via the losses icon in the PV*SOL Expert main menu (a white bar in a red circle). Please note that you have to choose "free-standing" if you like to plan mounted systems.

Photovoltaics

This message means that an important hardware feature for the 3D display is not available on the graphics card being used.

Possible reasons for this:

- DirectX version lower than 9.0c.

- DirectX 9.0c is not supported by your graphics card.

- You are using a terminal server solution. The DirectX graphics component is not capable of running on a terminal server.

- You are using a Windows emulator. Not all Windows emulators support DirectX.

In many cases an update of your graphics card drivers can help.

Photovoltaics

Go to the menu "System" - "Technical Data" and then choose the "PV Array" tab. For mounted systems select the installation type "Free-Standing". You can either enter a set number of modules (select "Define Module Number") or you can select "Determine Output from Roof Area", in which case you can click on the "Roof Parameters" button to open the corresponding dialog. With mounted systems ("Free-Standing" installation type) and "Determine Output from Roof Area" when you click on the "Roof Parameters" button an additional dialog appears showing the minimum distance between modules.

Please note that mutual shading of the modules is not taken into account in the simulation.

How do I design a mounted system in the 3D visualization of PV*SOL Expert? Learn more here.

Photovoltaics

All modules are calculated with the part-load characteristic curve (efficiency or ETA curve). The specific part load operation for the modules is in some cases given by the manufacturer (see "Databases" - "PV Module" - "U/I Char. – Part Load"). In all other cases a characteristic curve is used that is specific to the cell type. It is possible to select from 11 different cell types. For the 5 thin film types: amorph, HIT, CIS, CdTe and triple a-Si, standard characteristic curves are available for typical part load operation. For the other 6 cell types the standard operation for monocrystalline modules is used.

Photovoltaics

The specific annual yield is calculated as follows:

specific annual yield = (energy produced by PV generator – energy from grid / (exact) PV output

Four decimal places are included in the calculation. The value for the energy from grid can be viewed in the "Results" – "Annual Energy Balance" dialog and in the Detailed Project Report.

Photovoltaics

The energy from grid is comprised of the appliance’s electricity requirement which is met by the grid (if connected) and the PV system’s own requirement (for inverter stand-by and night use).

Photovoltaics

The current feed-in tariffs can be downloaded from the Download area of our website. Please save and extract the *.zip file in the tariff folder of your PV*SOL program. Under "Options" - "Paths" - "Electricity Tariffs", you can see where the tariff folder is kept on your computer. If you want to set the new feed-in tariff as the "Standard Feed-in Tariff for New Projects", you can update this under "Options" - "Settings" - "Projects".

In PV*SOL advanced and PV*SOL basic the new feed-in tariffs are delivered via database update.

Photovoltaics

Start a new project with the option "System Planning without 3D visualization".  Open the "Technical Data" dialog. In the "Technical Data" dialog window please change to the "PV Array" tab and choose the option "Create preview of roof layout with Photo Plan". The button "Photo Plan" is now activated and you can access to Photo Plan.

Please note that Photo Plan is only available starting PV*SOL Pro 4.5 and PV*SOL Expert 4.5.

Photovoltaics

Please go to the "Electricity Tariff" window by choosing "Conditions" and then "Tariffs (Grid Connected Systems)" in the menu bar. Now select the "Net Metering" option. Leave the window with the "OK" button. Your entries made previously retained when switching between the grid concepts.

Photovoltaics

Usually the reason for that is the part load operation behavior of the modules. The specific data for every module are entered in the database by the manufacturers. They have the possibility to enter a specific part load operation point for their modules in our database. Then a specific part load operation curve is calculated for the module. If the manufacturer don’t enter the specific part load operation point and select the "standard part load operation" option a curve for the cell type is used (e.g. monocrystalline) for the calculation. Which part load operation curve is used for the selected modules can be seen in the database.

Photovoltaics

In PV*SOL premium and PV*SOL please open the tariff database via "Databases > feed-in tariffsand select the icon "New". Afterwards enter the required data.

To create your own feed-in tariffs in PV*SOL Pro/Expert you have to select the feed-in option in the databases menu. Please enter a name and choose your preferred country. Now insert the period of validity for tariff, the number of power levels and the inflation. Afterwards you can enter the feed-in payments in the table. Finally you have to save the file.

Photovoltaics

In PV*SOL advanced the Excel export can be found in the presentation window.

In PV*SOL Pro/Expert you are able to have a look at the detailed results via the “Energy and Climate Data” button. Please select your preferred data. With a click on “Table” you can switch the graph display to the table display.  Thereafter you are able to change the values to different intervals (e.g. week, month, year) by using "x-axis".  Use “File” => “Copy” to transfer the data to the clipboard. In Excel you can now insert the data with “paste”.

Photovoltaics

In PV*SOL premium and PV*SOL you will find these settings in the window climate, grid and system type under AC Mains.

In PV*SOL Pro/Expert please use the Feed-in Management of the Losses window. Here you can set the maximum feed-in in percentage of the nominal maximum pv array power. If you for example have 40 modules of 200 W then your theoretical maximum power is 8 kW. In the losses window you have to enter 75 % to reach a maximum feed-in power of 6 kW.

Photovoltaics

Power optimizers can be assigned to the PV system, one or several subsystems or one or several inverters in the tree view of the configuration. Please select first the configuration which should be used with power optimizers. Afterwards activate the power optimizer option by clicking on the "Star" icon.
