PV*SOL: cost, fit and limits
PV*SOL is a photovoltaic planning and simulation software made by Valentin Software GmbH, offered as a premium and a standard desktop line with a component database, a free online calculator, an API and a downloadable trial; it names no AI capability on the pages opened.
What to know first
PV*SOL belongs to a Valentin Software family that also includes T*SOL and GeoT*SOL for thermal and geothermal design. The product page publishes no prices, the order links lead to an external shop, and a trial version can be downloaded without a stated length. An Application Programming Interface and a Custom Software offering are listed as separate product lines, again without prices or limits.

Who PV*SOL is best for
Planners who want a desktop tool
The product line is offered as downloadable desktop software with a trial, which suits engineers who size systems locally rather than in a browser.
Users who need a quick estimate
PV*SOL online is a free online calculator listed beside the desktop product, a low-cost way to check a rough design before buying.
Firms that integrate planning into other systems
The vendor lists an Application Programming Interface as its own product line, and a Custom Software offering, for companies that want PV*SOL logic inside their own tools.

What PV*SOL does
- PV*SOL database
- The vendor names a PV*SOL database as part of the product line, described as a component library for modules and inverters used when sizing a system.
- PV*SOL online
- A free online calculator is listed next to the desktop product, so a user can try a simple estimate in a browser before downloading or buying software.
- Application Programming Interface
- An API is listed as its own product line on the vendor's page, though the page gives no description of its endpoints, limits or pricing.
- Custom Software
- The vendor lists a Custom Software offering, which suggests bespoke development, though the page does not describe what projects it covers or how they are priced.
- Trial version
- A downloadable trial version of the product line is offered, but the page does not say how long it runs or which functions it restricts.
How PV*SOL handles your data
The pages opened are the English homepage and imprint, and neither states how customer data is handled. Training on customer data, retention, hosting region and security certifications are not stated. The homepage lists memberships in DGS, BSW, BWP and ISES, which are trade and science associations, not certifications. Valentin Software GmbH is named in the imprint, and the company's country is given there as Germany. Because PV*SOL is desktop software, project files may sit on local machines, but the page does not say what the online calculator or any cloud component stores.
Where PV*SOL falls short in practice
- Prices hidden. No price is published on the pages opened and orders go through an external shop, so license cost cannot be compared from the vendor site.
- No AI named. The pages opened name no AI capability, so a buyer looking for automatic roof detection or generated layouts will find nothing to evaluate and must test the trial directly.
- Trial details missing. The length of the trial and any feature limits are not stated on the page opened, so a buyer must download it to learn what it does and does not allow.

Alternatives to PV*SOL
PV*SOL: common questions
Does PV*SOL publish prices?
No. The product page lists no prices, and the Order now links go to an external shop. A trial version can be downloaded, but its length is not stated. Contact Valentin Software or check the shop for the current license cost.
Is there a free version of PV*SOL?
The vendor lists PV*SOL online, a free online calculator, next to the desktop product, and offers a downloadable trial version. It does not describe either as a full free plan, and the trial length and limits are not stated on the page opened.
Does PV*SOL have an API?
Yes. The vendor lists an Application Programming Interface as its own product line, alongside a Custom Software offering. The pages opened give no detail on what the API covers, how it is licensed or what it costs, so ask the vendor before planning an integration.
Does PV*SOL use AI?
No AI capability is named on the vendor pages opened. The product line is presented as planning and simulation software with a component database and an online calculator. A buyer who needs AI roof modeling should compare it with tools that name those features.
What else does Valentin Software sell?
The product page also lists T*SOL and GeoT*SOL, thermal and geothermal design products, plus a Custom Software offering and an API. They matter to firms planning solar thermal or ground-source heat as well as PV, since they share one vendor.
