With PV*SOL premium, the industry standard for photovoltaic design software, you can design and simulate all types of modern PV systems. From small rooftop systems with to medium-sized systems on commercial roofs to solar parks - PV*SOL premium supports you with numerous tools for design and simulation. The unique 3D visualization is the highlight of PV*SOL premium. You can visualize all common types of systems in 3D, whether roof-integrated or roof-mounted, whether on small angled roofs, large industrial halls or open spaces - with up to 7,500 mounted modules or up to 10,000 roof-parallel modules - and calculate the shading based on 3D objects. With the realistic shading from surrounding objects, you can achieve the highest reliability for your yield forecast. All other design types from PV*SOL are of course also available in PV*SOL premium. Whether calculating self-consumption, designing battery storage or integrating electric vehicles - with PV*SOL premium you can implement all customer wishes in no time at all. Our extensive product database includes over 26,000 PV modules, 7,500 inverters, 5,500 battery systems and many other products such as electric vehicles and performance optimizers. It is updated regularly by the product manufacturers themselves, so you can always work with the latest data. You can generate high-quality project reports for your customers that can be edited as required. Circuit diagrams with the necessary safety devices can also be created, e.g. for submission to the relevant authorities. The current feed-in tariffs are available in our database for the calculation of economic efficiency. By adding the information to the system costs, you will receive a detailed economic analysis of the system over 20 years. This allows you to create an initial offer in just a few minutes. PV*SOL premium is available in German 🇩🇪, English 🇬🇧, Spanish 🇪🇸, French 🇫🇷, Italian 🇮🇹, Polish 🇵🇱, Czech 🇨🇿, Portuguese 🇵🇹 and Turkish 🇹🇷. And with project reports available in 23 languages, language barriers are a thing of the past. Our technical support team and our help pages offer you assistance with your questions. In our forum you can address more complex questions to our team and other PV*SOL premium users.

The following bugs have been fixed: - A message is displayed if a surplus consumption has been defined but only one from-grid tariff has been selected. - An example project with Rexplorer API planning has been added. - The “Report a Problem with the Rexplorer Model” dialog has been revised. - The state (open, collapsed) of the group boxes in the 3D map tool is now saved. - If the program fails to start, the system now checks whether there are any special characters in the installation path. The following bugs have been fixed: - Crash after deleting a load profile from measured values whose name had just been changed. - Crash in the tree view of the load profile dialog. - The number of cables in the circuit diagram was sometimes displayed incorrectly. - Options dialog: The checkbox for NEC temperature calculation was not visible. - Crash when displaying plans if they were transferred twice from 3D. - 3D: - An attic could not be defined for 3D models. - When using Rexplorer API, a reference edge could not be selected when defining a mounting system. - When the default edge was selected, the correct orientation was not shown on the info button. - Error messages related to the Rexplorer API have been revised.
2026.6Jun 10, 2026
The following bugs have been fixed: - No circuit diagram was generated when special characters were used. - Rexplorer data were not imported into the 3D planning if data already existed and the “New Project” option was then selected from within the 3D environment. Features and bug fixes in PV*SOL premium 2026 R5 The following new features and changes are included: - System planning using automatically generated 3D building models from LiDAR scans of the Rexplorer API (available only for locations in Germany). - New map providers for planning with map sections for Spain and France. - Updated TMY climate data from SolarAnywhere. - Configuration rules for the SolarEdge S500B W, S650B W, and S650A power optimizers have been integrated. - New load profiles: - BDEW load profiles H25, G25 and L25 - Elexon UK load profiles (Class 1 to Class 8) - Catapult UK load profiles - Load profiles based on measured values can be copied. - Options menu with a new layout. The following bugs have been fixed: - Time controlled charging/discharging for DC battery systems spanning periods beyond midnight (00:00) did not work. - Error when simulating DC charge controllers. - Partial crashes occurred when using PVGIS climate datasets in combination with multiple module areas. - The energy yield for GEG was not updated after changing the degradation. - Global radiation and the diffuse fraction were not displayed in the characteristic curve diagram. …

GIMP is an acronym for GNU Image Manipulation Program. It is a freely distributed program for such tasks as photo retouching, image composition and image authoring.
Inkscape is an open-source vector graphics editor similar to Adobe Illustrator, Corel Draw, Freehand, or Xara X. What sets Inkscape apart is its use of Scalable Vector Graphics (SVG), an open XML-based W3C standard, as the native format. In contrast to raster (bitmap) graphics editors such as Photoshop or Gimp, Inkscape stores its graphics in a vector format. Vector graphics is a resolution-independent description of the actual shapes and objects that you see in the image. A rasterization engine uses this information to determine how to plot each line and curve at any resolution or zoom level. Contrast that to bitmap (raster) graphics which is always bound to a specific resolution and stores an image as a grid of pixels. Inkscape can import and display bitmap images, too. An imported bitmap becomes yet another object in your vector graphics, and you can do with it everything you can do to other kinds of objects (move, transform, clip, etc.) While Inkscape does not have all the features of the leading vector editors, the latest versions provide for a large portion of basic vector graphics editing capabilities. People report successfully using Inkscape in a lot of very different projects (web graphics, technical diagrams, icons, creative art, logos, maps).
