# Message test — https://ratedpower.com/ After reading your page, 15 of 15 personas could name what kind of product this is, unprompted — and clarity was the weakest of the four. - **Page tested:** https://ratedpower.com/ - **Audience tested against:** Heads of engineering and senior PV design engineers at utility-scale solar and BESS developers, EPCs and engineering consultancies with 15–250 staff, mostly in Europe (Italy, Iberia, the UK, DACH). Today they screen sites and build layouts in Excel, AutoCAD and Google Earth, and check yield in PVsyst, which they'll keep using. They have more projects in the pipeline and more tenders due than engineers to design them, so every go/no-go call waits on manual rework. They buy a €15–30K annual licence once the design engineers have tested it and the engineering lead signs off. Not for rooftop, residential or C&I installers, utilities, banks and funds, equipment suppliers, or teams looking for a free self-serve trial. - **Personas:** 15 simulated - **Report:** https://grader.wynter.com/r/ai-powered-solar-pv-and-bess-design-enverus-ra-0riL2C0 > These answers are generated by AI, scored on Wynter's B2B Message > Layers framework using behaviorally-diverse simulated personas.

These are four independent proportions of the same panel, not stages of a funnel. | Layer | Question | Cleared the bar | Strength | Of those who passed | | --- | --- | --- | --- | --- | | 1. Clarity | Do they understand what you do? | 15/15 | 93% | 10 without hesitation, 5 with reservations | | 2. Relevance | Can they tell what it solves, and who it's for? | 15/15 | 97% | 13 without hesitation, 2 with reservations | | 3. Value | Do they actually want it? | 15/15 | 78% | all with reservations | | 4. Differentiation | Is there a reason to pick you over the alternatives? | 15/15 | 78% | all with reservations | **Brand alignment** (a side metric, not one of the four layers) — 15/15, 78% strength (all with reservations). Does the page read like the company you actually are? **Fix first: Clarity.** Earliest failing layer, walking the sequence in order — not simply the lowest score. --- ## 02 · What to change, layer by layer Ordered worst-first. Specific edits, not a restatement of the score. ### Value **Add baseline and method under the three numbers in the "three numbers move" band.** A reader cannot tell what 160x, 5% LCOE and 20% asset profit are measured against, or over how many projects. State the comparison base, sample size and who calculated them, right beside each figure. *effort medium · impact high · tested against Proof next to the claim* **Add a source line under "20% more asset profits" naming the projects behind it.** The profit claim sits alone while the Black & Veatch audit carries its own evidence. Attach a named project, portfolio or customer to the profit and time savings figures the same way. *effort low · impact medium · tested against Proof next to the claim* ### Differentiation **Expand the DWG round-trip line to say which data is lost and when.** "The round-trip is not lossless in every case" tells a civil team nothing about what breaks, so they assume the worst. Name which elements survive export and import, the cases where they do not, and the workaround. *effort medium · impact high · tested against Answer the live objection* **Add one line after the Black & Veatch audit offering validation on the reader's own site.** Buyers want to know the software holds up on messy real terrain, not a reference case. Say that you will run their site and reconcile the yield, and how to request it. *effort low · impact medium · tested against Answer the live objection* --- ## 03 · What is working ### The offering reads clearly as one-pass PV/BESS design automation replacing the… Six respondents described the product back accurately: AI automating GIS screening, layout, yield, electrical and CAPEX in a single pass instead of manual CAD and spreadsheets. The 160-layout figure was memorable and repeatable. > PV/BESS design automation software, basically a faster replacement for the CAD/PVsyst/spreadsheet stack I'm using now. > > — Senior PV Design Engineer, Renewable energy consulting, 11-50 > It's AI-driven design software for utility-scale solar (and storage/hybrid) projects — it takes a site through layout, yield simulation, electrical design and CAPEX/documentation in one automated pass > > — Principal PV Design Engineer, Solar energy, 51-200 > takes a site from GIS screening through layout, energy yield and CAPEX in one automated pass instead of doing it by hand in CAD and spreadsheets > > — Senior PV Design Engineer, Engineering and construction, 51-200 > The pitch was "160 layouts instead of one," which stuck because it's a concrete number, not because I trust it yet - I'd want to see that run on our own site data before buying in > > — Engineering Lead, Energy storage, 201-500 ### Named customers and specific workflow metrics made the tool feel real Two respondents cited named customer quotes with specific workflow reductions as establishing credibility that this is a working tool rather than a pitch. > The customer quotes (Engie, Akuo, Recurrent Energy, RES Group) naming actual workflow reductions like "50% of overall engineering workflow" and "30 to 40%" are what actually convinced me this is a real design tool and not just a buzzword wrapper. > > — Head of Engineering, Renewable energy, 11-50 > The named customers - Engie, Akuo, RES Group, Recurrent Energy - and specific figures like "30 to 40% engineering time reduction" and DWG export into AutoCAD make it credible as a real design tool rather than vapourware > > — Head of Engineering, Energy storage, 51-200 ### The first screen states the problem and who it is for without inference Nine respondents said the hero establishes the problem, the named buyer job titles and the target personas immediately. Several noted this removes guesswork about audience, though one still found the primary target ambiguous. > the hero line "AI-optimized pass takes your project site all the way to layout, yield, electrical design, CAPEX and 400+ editable pages of documentation... in up to 90% less design time" tells me the problem (slow one-scenario-at-a-time design in spreadsheets/CAD) and the fix in one breath > > — Senior PV Design Engineer, Renewable energy consulting, 11-50 > "A single site takes a day or two, so you run two options instead of twenty." That's my PVsyst/CAD reality. > > — Principal PV Design Engineer, Solar energy, 51-200 > It's obvious within the first line - "AI-powered design and engineering for utility-scale PV, storage and hybrid" tells you what it does, and the subhead "Screen with confidence. Engineer without delay" tells you the problem it's solving: slow, one-scenario-at-a-time manual design work > > — Engineering Lead, Energy storage, 201-500 > The "one scenario at a time" section spells the pain out explicitly: teams "build layouts in spreadsheets and CAD, one scenario at a time," a site "takes a day or two," so you "run two options instead of twenty." As for the audience, it's not left to guesswork either — the "Built for every team" section names developers, EPCs, banking/finance, consulting, IPPs, utilities, engineers and engineering leaders directly > > — Head of Engineering, Renewable energy, 11-50 > they spell out the audience explicitly later with the "By industry / By role" tabs - developers, EPCs, banking and finance, IPPs, utilities, engineers - so I didn't have to infer who it's for > > — Senior PV Design Engineer, Engineering and construction, 51-200 > the "Built for every team" section lists developers, EPCs, banking/finance, consulting, IPPs, utilities, engineers and executives by name, and the testimonials come from exactly those job titles > > — Principal PV Design Engineer, Renewable energy consulting, 201-500 > there's a literal "By role" list - developers, EPCs, banking/finance, consulting, IPPs, utilities, engineers, engineering leaders - so I didn't have to guess who this is for > > — Head of Engineering, Energy storage, 51-200 > it's split between selling me on technical credibility and selling my boss on ROI. > > — Senior PV Design Engineer, Renewable energy, 201-500 ### The Black & Veatch audit against PVsyst is the only proof respondents believed Eight respondents singled out the third-party yield reconciliation as concrete, checkable and the main thing separating the page from competitor marketing claims. Two wanted it extended to hybrid dispatch or their own site. > The Black & Veatch audit number (+0.24% to +1.08% vs PVsyst) is the one bit of proof that would actually let me trust the yield output rather than just the marketing > > — Senior PV Design Engineer, Renewable energy consulting, 11-50 > The Black & Veatch PVsyst reconciliation number (+0.24% to +1.08%) is the one bit of proof on the page that isn't just a customer quote, and that's what would get me to a meeting rather than a "thanks, pass." But I'd want that demo run on one of our actual sites with our BESS dispatch data before I take it further > > — Engineering Lead, Energy storage, 201-500 > The DWG round-trip export in the Layout Editor is the specific thing that would tip a shortlist decision my way — the page is honest that "the round-trip is not lossless in every case," which is actually a point in its favor because it's the kind of caveat you only write if you've tested it, and it directly answers my team's fear of being locked out of AutoCAD. Combined with the Black & Veatch audit figure ("+0.24% to +1.08%" against PVsyst), that's the one yield claim on the page with an actual named third party and a number I could go check > > — Head of Engineering, Renewable energy, 11-50 > The Black & Veatch audit line - "+0.24% to +1.08%" against PVsyst - is the one thing that would actually pull me toward this over a competitor, because it's a named third party checking the yield number > > — Senior PV Design Engineer, Engineering and construction, 51-200 > The Black & Veatch audit line — "+0.24% to +1.08%" against PVsyst — is the one concrete thing that would push it onto my shortlist over a competitor with no third-party number > > — Principal PV Design Engineer, Renewable energy consulting, 201-500 > The Black & Veatch audit line - "+0.24% to +1.08%" against PVsyst - is the one thing here that would actually move it up my shortlist, because it's a named third party and a checkable number, not marketing fluff. > > — Engineering Lead, Solar energy, 11-50 > Getting a real project through the tool end to end - one of our own sites, our own terrain and grid constraints - and seeing the layout export cleanly into AutoCAD without my team having to redraw half of it by hand. > > — Engineering Lead, Solar energy, 11-50 --- ## 04 · What the personas said ### The headline numbers have no baseline or methodology behind them Four respondents said claims like 160x speed, 5% LCOE and the profit and time savings lack stated baselines, methodology or evidence, including how the Power Analyst search works. One wanted a budget comparison against current CAD and Excel costs rather than… > "5% less LCOE" and "20% more asset profits" have no baseline or methodology attached, so I'd push them to show the calculation, not just quote it, before I take this further internally. > > — Head of Engineering, Renewable energy, 11-50 > phrases like "runs the whole design matrix," "searches the design space," and "applies the right CAPEX templates to each combination" describe outcomes but never the actual search method (is it exhaustive, gradient-based, some heuristic?) > > — Principal PV Design Engineer, Renewable energy consulting, 201-500 > the "5% LCOE" or "20% more asset profits" numbers, which have no baseline or source and I'd ignore until proven > > — Engineering Lead, Solar energy, 11-50 > A named budget line against a named alternative - what a consulting firm my size actually pays per year for this versus current CAD/Excel licenses and hours, not a generic ROI calculator I have to go build myself. > > — Engineering Lead, Renewable energy consulting, 51-200 ### The DWG round-trip lossiness caveat is read as a deal-breaker Six respondents flagged the CAD round-trip data loss as the page's biggest risk: it creates friction with civil and engineering teams and could eliminate the tool if a competitor offers lossless round-trip. One counted the disclosure itself as… > "the round-trip is not lossless in every case" on the DWG export is a real rule-out risk for me, since my whole workflow depends on handing edited layouts back to civil in CAD without corruption - if a rival tool doesn't have that caveat, or specifies exactly what breaks, they win on that line alone > > — Senior PV Design Engineer, Renewable energy consulting, 11-50 > the CAD round-trip note ("The round-trip is not lossless in every case") almost rules it out on its own, since that's exactly where our real workflow would break > > — Principal PV Design Engineer, Solar energy, 51-200 > "The round-trip is not lossless in every case" for the CAD export is a genuine red flag they chose to disclose - it's honest, which I respect, but it also tells me there's friction in exactly the workflow step where our engineers would push back hardest > > — Engineering Lead, Energy storage, 201-500 > the DWG round-trip line — "not lossless in every case" — is exactly the kind of caveat that tells me adoption friction with our civil team is real, not hypothetical > > — Principal PV Design Engineer, Renewable energy consulting, 201-500 > the DWG export caveat "not lossless in every case" would rule it out if a competitor doesn't have that same asterisk on their CAD round-trip, since half my team's workflow lives in AutoCAD > > — Engineering Lead, Solar energy, 11-50 > The DWG round-trip export in the Layout Editor is the specific thing that would tip a shortlist decision my way — the page is honest that "the round-trip is not lossless in every case," which is actually a point in its favor because it's the kind of caveat you only write if you've tested it, and it directly answers my team's fear of being locked out of AutoCAD. Combined with the Black & Veatch audit figure ("+0.24% to +1.08%" against PVsyst), that's the one yield claim on the page with an actual named third party and a number I could go check > > — Head of Engineering, Renewable energy, 11-50 ### Claimed advantages are conditional on performance with messy real sites Two respondents said the speed and yield-audit advantages only matter if the software holds up on real, messy sites, and wanted validation on a project of their own. > Watching it take one of our own messy sites - not their demo site - through to a layout and yield number that's within a few percent of what my team already produced by hand, in minutes instead of days > > — Senior PV Design Engineer, Engineering and construction, 51-200 > Getting a real project through the tool end to end - one of our own sites, our own terrain and grid constraints - and seeing the layout export cleanly into AutoCAD without my team having to redraw half of it by hand. > > — Engineering Lead, Solar energy, 11-50 ### The copy is written for engineers rather than generic digital-transformation buyers One respondent praised the engineer-specific pain points over generic transformation language; another said the marketing layer obscures whether this is a single product or a bundle. > it doesn't oversell with generic "digital transformation" language, and quotes like "the turnaround time on everything is maybe 10% of what it was before" sound like something an actual engineer said, not marketing copy > > — Engineering Lead, Engineering and construction, 201-500 > If anything got in the way it's the marketing layer stacked on top of the description, phrases like "screen with confidence" and the four-part "GIS/Layout/Yield/AI" naming that make me re-read to confirm it's still one product and not a bundle of four. > > — Engineering Lead, Renewable energy consulting, 51-200 --- ## 05 · The hardest read An adversarial pass over the findings. Every claim below was checked against the panel's own answers; unsupported ones were dropped. - **One disclosed caveat outweighs every benefit claim on the page.** *(high)* Six respondents named the DWG round-trip data loss as the biggest risk and a reason a lossless competitor wins, more than the five who described the offering correctly. A single line of fine print is doing more work than the entire value argument. - **The page's quantified claims are unverifiable and therefore load-bearing on nothing.** *(high)* Four respondents said 160x speed, 5% LCOE and the profit and time savings carry no baseline, methodology or evidence, and one asked for a budget comparison against current CAD and Excel spend. Numbers without a denominator are decoration. - **Credibility rests on a single borrowed proof point, leaving the page fragile.** *(high)* Eight respondents named the Black & Veatch PVsyst reconciliation as the only believed proof and the one thing separating the page from competitor marketing. Everything else — headline metrics, customer quotes — sits below it, and only two cited the named… - **Buyers do not accept that the demonstrated performance transfers to their own projects.** *(medium)* Two respondents said the speed and yield advantages only matter if the software holds up on messy real sites and asked for validation on a project of their own; two more wanted the audit extended to hybrid dispatch or their site. The proof is read as a demo… - **The product architecture is unclear: buyers cannot tell what they would actually be purchasing.** *(medium)* One respondent said the marketing layer obscures whether this is a single product or a bundle, and one found the primary target ambiguous despite the hero naming personas. Scope ambiguity blocks procurement even when the pitch lands. - **Audience clarity is the page's only uncontested strength, and it stops at the hero.** *(low)* Nine respondents said the first screen names the problem, job titles and personas without inference — the highest agreement on the page. Below the fold, agreement collapses to six on the round-trip risk and four on missing methodology. --- ## 06 · Who answered | # | Role | Industry | Company size | | --- | --- | --- | --- | | 1 | Senior PV Design Engineer | Renewable energy consulting | 11-50 | | 2 | Principal PV Design Engineer | Solar energy | 51-200 | | 3 | Engineering Lead | Energy storage | 201-500 | | 4 | Head of Engineering | Renewable energy | 11-50 | | 5 | Senior PV Design Engineer | Engineering and construction | 51-200 | | 6 | Principal PV Design Engineer | Renewable energy consulting | 201-500 | | 7 | Engineering Lead | Solar energy | 11-50 | | 8 | Head of Engineering | Energy storage | 51-200 | | 9 | Senior PV Design Engineer | Renewable energy | 201-500 | | 10 | Principal PV Design Engineer | Engineering and construction | 11-50 | | 11 | Engineering Lead | Renewable energy consulting | 51-200 | | 12 | Head of Engineering | Solar energy | 201-500 | | 13 | Senior PV Design Engineer | Energy storage | 11-50 | | 14 | Principal PV Design Engineer | Renewable energy | 51-200 | | 15 | Engineering Lead | Engineering and construction | 201-500 | --- ## 07 · Before you act on this The methodology is real, and the critique is directional.
