PV*SOL Review: An Honest Verdict for Installers

Most reviews of PVSOL are written by people who have never had to sell a shading loss to a sceptical homeowner. That is the wrong lens. PVSOL premium is not competing to be the most rigorous yield engine in the world, and it does not need to be. It is competing to make a customer understand, in about 8 seconds, why the tree on the south boundary costs them money. On that job it is genuinely the best thing on the market.

Direct answer. PV*SOL premium is excellent at customer-facing 3D shading visualisation and at self-consumption and battery modelling, which fits European markets moving off net metering. Its weaknesses are structural: desktop and single-user, and it stops at the design layer. For most installers and EPCs, SurgePV covers design, shading, drawings, and proposals in one browser licence.

What PV*SOL Is, and Who It Is Actually For

PV*SOL is desktop simulation software from Valentin Software, a German company that has been in this market a long time. That history matters. The product was built inside the country with the deepest solar operating record in the world, for installers whose customers check the meter against the proposal.

The audience it fits best is a European residential or small commercial installer who sells face to face. Someone sits at a kitchen table, opens a laptop, and shows the customer the roof in 3D with the shadow moving across it through the year. That is the workflow PV*SOL was designed around, and it is a genuinely good one.

It is not built for a 40-person EPC with designers in 3 offices sharing work in progress. It is also not the tool a lender expects to see behind a financed asset. Knowing which of those you are is most of the buying decision.

PV*SOL Pricing and Editions

Valentin prices in euro. The entry editions start around €1,000, and the premium edition that carries the detailed 3D modelling and shading visualisation sits above that. Exact figures move with edition, term, and reseller, so treat published numbers as a starting point and get a quote for the seat count you actually need.

Two things are worth flagging before you sign.

First, the 3D shading visualisation is the reason most buyers want this product, and it lives in the premium edition. Buying a cheaper edition and discovering the gap later is the most common budgeting mistake on this product.

Second, the licence is per seat and desktop. A second designer means a second seat and a second install, not an invitation link. For a 2-person shop that is nothing. For a team that adds 4 designers a year it compounds.

Our solar design software pricing breakdown puts these numbers next to the rest of the category.

What PV*SOL Does Better Than Anything Else

Start with the thing it wins outright.

The 3D shading visualisation. PVSOL premium lets you build the surroundings, trees, dormers, chimneys, neighbouring buildings, and then render the shadow moving across the array. It is animated, it is legible to a non-engineer, and it is convincing. Every design tool in this category calculates shading. PVSOL is the one that shows it in a way a customer accepts without argument. If you sell in person, that animation is a closing instrument, and I have not seen a competitor match it on that specific axis.

That has a second-order value people underrate. A customer who has watched the shadow crawl across the array understands why the modelled yield is lower than the number a rival quoted. The animation does not just sell the system, it defends the honest number against an optimistic competitor. In a market where owners compare production against the proposal, that is worth real money.

Self-consumption and storage modelling. This is the other genuine strength, and it is timely. European markets have been moving away from net metering, which changes the economics from “how many kilowatt hours does the array make” to “how many of them does the household use itself”. PV*SOL models that behaviour properly, with battery dispatch and load profiles, rather than treating storage as a bolt-on. If your proposals live or die on self-consumption share, this is a serious product.

Local fit. It is a German tool for a German-shaped market, and it shows in the defaults, the component libraries, and the assumptions. That is not glamorous, but it removes friction every single day.

Where PV*SOL Falls Short

Now the honest part.

It is desktop and single-user in posture. Projects live on a workstation. Sharing work in progress means files on a drive, a naming convention, and a rule nobody follows. A senior engineer cannot glance at a junior’s layout without either sitting next to them or waiting for a file. For a 2-person team this is invisible. At 6 designers it is a daily tax, and at 15 it is a process problem you have to hire around.

It solves one layer. PVSOL produces a design and a simulation report. It does not produce a permit drawing set, and it does not produce a white-label customer proposal in the way a sales platform does. So the design lands in PVSOL, the drawings get redrawn in CAD, and the proposal gets assembled in a deck template. Two handoffs, both manual, both places where a change to the array silently fails to propagate.

It is not the bankability reference. PVsyst still holds that position with lenders and independent engineers. That is not a criticism of PV*SOL’s engine, it is a market fact. If your projects get technically reviewed by someone else’s bank, you will be asked for PVsyst output.

The visualisation strength does not transfer to paper. The animation is the product’s best feature and it only exists on a screen in front of a customer. Remote or web-based sales motions capture less of it.

PV*SOL vs SurgePV

	PV*SOL premium	SurgePV
Delivery	Desktop, Windows-oriented	Browser-based
Collaboration	Per-seat, file-based	Shared workspace by design
Simulation	Hourly annual simulation	8,760-hour with module-level shading, mismatch, string topology
Customer-facing shading	Animated 3D rendering, best in category	Shading modelled and reported, not an animation
Storage and self-consumption	A core strength	Not claimed here
Permit drawings	Not a drawing set producer	Single-line diagrams and DWG export from the same model
Customer proposal	Engineering report output	White-label proposal layer included
Price	Around €1,000 upward by edition	$1,299 to $1,899 per user per year
Bankable yield standard	No, PVsyst holds that	No, PVsyst holds that

Read that table honestly. There is one row where PVSOL wins and no amount of feature count changes it: the animated 3D shading rendering. If that animation is what closes your sales, PVSOL is hard to replace, and you should keep it.

The rows where SurgePV wins are structural rather than clever. It runs in a browser, so a growing team stops managing files. It runs an 8,760-hour simulation with module-level shading, mismatch, and string topology, so the loss numbers come from the array as built rather than an average. And it emits the single-line diagram, the DWG, and the customer proposal from the same model that produced the yield figure. One licence spans design, shading, and proposal.

The Two Licences for One Layer Problem

Walk into a mid-sized German firm and you will often find PVSOL and PVsyst both on the invoice. Ask why, and the answer is reasonable: PVSOL sells the job, PVsyst defends the number. Nobody is being stupid.

But look at what has been bought. Both products occupy the same layer of the stack. Both take a roof and produce a yield. The firm is paying twice for design and simulation, and still paying a third time in labour for the drawings and the proposal, which neither tool produces. That is 2 licences covering one layer and 0 licences covering the other two.

The defensible version of this is a firm that genuinely needs lender-grade output. If your projects are financed and reviewed, keep PVsyst. That seat is buying acceptance, not features.

The indefensible version is a residential installer running both because the visualisation is in one and the credibility is in the other, on jobs no bank will ever look at. That firm is buying reassurance.

What Most Buyers Get Wrong

They evaluate design software on the yield number and never test the change path.

Here is the mechanism. In a demo you model one roof once, compare the annual kilowatt hours against a tool you trust, see agreement within a couple of percent, and conclude the products are interchangeable. They are not, because the demo never touched the thing that actually costs you money.

Real projects change. The site survey finds a vent stack. The customer drops 4 modules for budget. The structural review moves a row off the parapet. In a single-layer tool, that edit propagates through the design and then stops. Someone reopens the CAD file and moves the modules again by hand. Someone reopens the proposal deck and retypes the yield and the price. Both edits are done from memory, under time pressure, by a person who was not in the original review.

That is where errors enter, and they enter the 2 documents the customer and the inspector actually read. A tool that regenerates the drawing and the proposal from the same model removes the retyping step entirely. Test that in your evaluation. Model a system, change it materially, and count how many documents you have to touch by hand.

Who Should Buy Which

Buy PV*SOL premium if you are a European residential or small commercial installer selling in person, your close rate depends on showing customers the shadow, and self-consumption and battery sizing dominate your proposals. It earns its price on those jobs.

Keep PVsyst as well if your projects are financed and a lender’s engineer reviews the yield. That is a cost of doing that business.

Buy SurgePV if you have a growing or distributed design team, you produce drawing sets and customer proposals on every job, and you would rather pay for one licence spanning design, shading, and proposal than pay twice for the design layer and do the rest by hand.

Buy both if the animation is genuinely your closing tool and you also need the drawings and proposals produced at volume. That is an honest stack, not a compromise.

If the bottleneck is engineering throughput rather than software, that is a different purchase. Our solar rooftop detailed engineering design bench produces the construction pack directly. See a sample design pack or talk to our team.

The Verdict

PV*SOL premium is a good product that is very good at one thing, and the one thing is real. The 3D shading animation is the most persuasive customer-facing artefact in this category, and the storage and self-consumption modelling is aimed exactly where European tariffs are heading. Valentin has earned its position in Germany.

My opinionated call: for most installers and EPCs outside that specific in-person residential sales motion, PV*SOL is the wrong shape of purchase in 2026. Not because the engine is weak, but because it is a desktop, single-layer licence in a business that needs a collaborative, 3-layer one. You end up buying it, buying PVsyst next to it, and still producing your drawings and proposals by hand.

SurgePV is the recommendation for that majority. Browser-based, 8,760-hour module-level modelling, drawings and DWG export, and a white-label proposal layer, in one licence at $1,299 to $1,899 per user per year. Buy PV*SOL when the animation closes your deals. Buy SurgePV when the paperwork is what slows you down.

Conclusion

• PV*SOL premium wins on customer-facing 3D shading and on storage and self-consumption modelling. Those strengths are genuine and specific.
• Its limits are structural, not technical. Desktop, single-user, and design layer only.
• Most installers should consolidate rather than stack licences. One platform spanning design, shading, drawings, and proposal beats 2 seats covering the same layer.

FAQ

Is PV*SOL better than PVsyst? They are aimed at different jobs. PV*SOL premium is better for showing a customer where a shading loss comes from and for self-consumption and battery modelling. PVsyst remains the reference for bankable, lender-reviewed yield studies. Many European firms run both, which is defensible when projects are financed.

How much does PV*SOL cost? It is priced in euro, roughly €1,000 and upward depending on edition. The detailed 3D modelling and shading visualisation sit in the premium edition, so budget for that tier if visualisation is why you are buying.

Does PV*SOL run in a browser or on a Mac? It is desktop software, oriented to a single user per seat. Teams that standardise on browser-based tooling handle it with a Windows machine or virtualisation, which adds cost on top of the licence.

Can PV*SOL produce permit drawings? Not in the way a drawing package does. It produces design and simulation output. Permit drawing sets are prepared separately, usually in CAD, which is where the second manual handoff appears.

Does PV*SOL produce customer proposals? It produces engineering report output. It does not produce a white-label, brand-customised customer proposal the way a sales platform does, so most teams assemble that in a separate template.

Should I switch from PV*SOL to SurgePV? Switch if your team is growing or distributed, and if drawings and proposals are eating designer hours. SurgePV covers design, shading, single-line diagrams with DWG export, and a white-label proposal layer in one licence. Stay on PV*SOL if the animated 3D shading presentation is what closes your sales, because nothing replaces it on that specific strength.
