Valentin PV*SOL Premium Solar Design Software

Design PV Systems fast & precisely.

3D planning, yield simulation and comprehensive reports for professional quotes.

All in one software.

What is PV SOL?

PV*SOL and PV*SOL Premium are the industry-leading software design tools for simulating photovoltaic system performance. They are both full-featured programs with the difference being that PV*SOL Premium allows you to use 3D to model shading and visualise landscapes.

With PV*SOL Premium you can design a PV system in as little as 30 minutes and produce comprehensive reports for yourself and your client.

The PV*SOL software has been constantly optimised since 1998 and is at the cutting edge of the PV software market. This solar design software will not only help make solar design easier, it will make your design more precise, comprehensive and understandable to the client.

PV*SOL and PV*SOL Premium enable the planning of photovoltaic systems for very different system types – from a rooftop installation on a small family home to a large PV plant with up to 1,000 modules.

System designers are supported by clear step-by-step user guidance, constantly updated databases of climate and insolation data, as well as the data available on the market for modules and inverters.

The program gives system designers concrete configuration recommendations, but always allows the free configuration of the components.

The detailed project report generated presents the results clearly and thus provides useful support in reaching convincing decisions for all those involved in the implementation of the solar system.

Who is using it?

While PV*SOL is the preferred simulation software of some of the world’s biggest and most innovative solar companies, smaller solar businesses are also taking advantage of the solar design software.

Here is some feedback from solar installers experienced in using the software in projects big and small.

PV*SOL is a very powerful and user-friendly solar PV simulation tool. We use it to compile a professional proposal which includes 3D shading analysis, financials, solar PV panel layout, PV string, wiring layout, Bill of Materials and many other aspects into one report. We would highly recommend PV*SOL.

Can I run PV*SOL and PV*SOL Premium on Apple Mac computers or Linux systems?

Valentin software is developed to run on Windows operating systems. Additional software is required, such as VMWare or VirtualPC, in order to use Valentin programs on a Mac or with Linux.

Please note that Valentin Software don’t provide support for Mac or Linux installations but we are aware of many users who use this method. To establish compatibility prior to purchase of a licence, we encourage you to request your 2-week free trial of the PV*SOL Premium software. CLICK HERE

What capabilities and limitations do the demo versions have?

2-Week obligation-free demo / trial / test versions can be downloaded from our website – click here for demos. You will have access to all the program components and features except the customer report creation. You can use the program help to obtain an overview of the content and capabilities of the program.

After the trial period has expired, you will no longer have access to the program and you will need to ask us to quote for a full license.

Can I use my own company logo in the project report?

Yes, you can import the desired logo directly into the program project report options. Alternatively, the report can be exported into Microsoft Word and further customised there.

How do I transfer my PV*SOL or PV*SOL Premium license to another computer?

You may wish to transfer a license because:

You have a new PC
Change of user
Hard drive replacement of existing PC
Hard drive reformatting of existing PC

When you made the original full installation you were ultimately asked to activate the program. Activation generates a unique keycode for each installation. You will not be able to make a second full installation of a license by simply copying the same original activation keycode (even if you try to install it on the same computer). You will however need the longer serial number and ideally this should first be recorded possibly via a screenshot of the original installation under the Menu > Help > Registration. Alternatively the original email you received with the license serial number will be required.

Before you can make a transfer, you will first need to de-activate the original install – this is different from simply deleting it. In any case you may wish to first back-up and make copies of your saved projects. You also may wish to export some program settings. Requesting a license re-activation will discontinue support of the original (current) installation. It is therefore not a facility for attempting to duplicate licenses and you should only request reactivation if you wish to transfer the license from one computer to another.

a) Program versions 2019 onwards allow self-deactivation providing the old computer is online. Use Main Menu > Help > Registration > Change Registration to do this. Then the license number can be used on another computer. This is limited to twice a year.

b) Where self-deactivation is not possible CLICK HERE to request a reactivation

After the request is sent you will eventually receive an email with a download link. Ensure this is the correct trial version to be installed on the target computer you wish to transfer to and check as far as possible that it functions correctly in trial mode. If you wish urgently use or transfer a current program (i.e. not a legacy program) the current trial versions can be quickly obtained via the Contact Us page. For legacy transfer requests we will first check if you are eligible for an update.

NOTE: You will need to uninstall the original program from your PC before being able to make the new installation. Please let us know if you are unable to do this (e.g. because of theft or damage to the original PC). You should give a reason in the box titled ‘Reason for reactivating’ on the form. Re-activation requests without deleting the original can take much longer to complete. If you wish to copy over your PV*SOL custom settings to your new computer, please first follow this link.

Please note: Old serial numbers that have already been updated cannot be re-activated. Instead you should use the new serial number that was sent as the replacement.

Can licenses be loaded centrally on our company server?

Single-user licenses are intended for use on an individual workstation. This means there cannot be simultaneous access to projects from other machines. However, the program on each workstation can be set so its databases and projects are stored at a single server location, hence allowing sequential access to stored projects by other licensed holders.

To note saved projects contain all the necessary design data so it is possible to store the active projects folder via a server. The default for this can be set via Main Menu > ‘Options’ > ‘Program Options’

Saved projects can only be sequentially accessed by users, and not simultaneously i.e. not in parallel.

Remote access to a licensed machine such as via VPN and Windows RDA is often feasible but not fully supported.
