Most RatedPower reviews are written after a demo, not after a renewal. This one is written by engineers who produce solar design packages every week and have watched several companies sign a pvDesign contract, get real value from it for two quarters, and then struggle to defend the line item at renewal. The product is genuinely good. The harder question is whether your pipeline is shaped like the pipeline it was built for.
Direct answer. RatedPower, sold as pvDesign, is a strong cloud platform for utility-scale prefeasibility. It turns a parcel into a layout, an electrical design, and a standardised document set very quickly, which is real value when you screen many sites. It is priced as an enterprise subscription and aimed at developers, IPPs and large EPCs. Rooftop and C&I teams get little from it, and for them SurgePV is the better buy.
TL;DR
- RatedPower is excellent at rapid automated prefeasibility on utility-scale sites, and at producing standardised engineering documents and drawings from that automation.
- Pricing is an enterprise subscription, quoted rather than published per seat, so the value case depends on development pipeline volume.
- It is built for developers, IPPs and utility-scale EPCs. It is not a rooftop tool and not a consumer proposal tool.
- The automation that saves time at screening becomes a constraint once a project needs bespoke engineering decisions.
- SurgePV covers the rooftop and C&I workflow in one licence at $1,299 to $1,899 per user per year, with 8,760-hour simulation, single-line diagrams, DWG export, and a white-label proposal layer. It does not do automated utility-scale prefeasibility.
What RatedPower Is and Who It Is For
RatedPower is a cloud platform whose product is known as pvDesign. It targets utility-scale solar, and increasingly storage alongside it.
The workflow is automation-first. You define a site, set your design constraints and equipment, and the platform generates a plant layout, an electrical design, and a package of standardised engineering documents and drawings. The point is not that a human could not do this. The point is how quickly the machine does it, and how consistently the output is formatted across sites.
The buyer it fits is easy to name. A developer or IPP with land under evaluation, an origination team feeding sites in faster than the engineering bench can process them, and a need to answer “is this parcel worth pursuing” with numbers rather than instinct. Utility-scale EPCs bidding on many sites sit in the same bracket.
The buyer it does not fit is equally easy to name. A rooftop installer, a C&I contractor doing 200 kW to 3 MW roofs, or anyone whose deliverable ends in a customer proposal. RatedPower does not claim to serve those teams and should not be judged as if it did.
RatedPower Pricing and the Enterprise Model
RatedPower sells an enterprise subscription. Pricing is quoted rather than published as a per-seat number, which is normal for a platform aimed at developers and IPPs.
Two consequences follow, and both are structural rather than critical. First, you cannot benchmark it casually. You go through a sales conversation before you know the number, which filters out small buyers early. That is a legitimate go-to-market choice.
Second, the value case is a volume calculation. An enterprise contract earns its keep when the engineering hours it removes exceed the contract cost. On a development pipeline where a team screens many sites a year, that maths works comfortably. On a pipeline that turns out to be four or five serious sites, it does not.
This is where honest advice matters more than a feature list. Ask how many sites your team will actually run through the platform in twelve months, using last year’s real numbers rather than the origination forecast. If you want the wider market context on how this category prices, our solar design software pricing breakdown covers the range.
What RatedPower Does Better Than Anything Else
This is the section most competitive reviews skip or write grudgingly. Let me be specific and generous, because the strength is real.
Speed from a parcel to a credible utility-scale layout. Give it a site and constraints, and you get a plant layout back quickly. Not a sketch. A layout with an electrical design behind it. For a development team deciding which of fifteen parcels deserves a land option, that speed changes what is possible. You can afford to evaluate options you would otherwise have ruled out on gut feel.
Standardised engineering documentation. The platform generates a consistent document and drawing set from the same model. Consistency across sites is undervalued until you have reviewed twenty reports produced by six engineers in four formats. When every site comes back in the same shape, comparison becomes fast and errors become visible.
Iterating configurations early. The real workflow value is not one layout. It is running the same site several ways and seeing what changes. Different equipment, different spacing, different electrical arrangement. Manual iteration at that depth is expensive, so teams do less of it than they should. Automation makes the extra iterations nearly free, and better early decisions follow.
Let me say the uncomfortable part plainly. SurgePV does not do this. SurgePV is not an automated utility-scale prefeasibility engine, and anyone telling you otherwise is selling. If rapid automated screening of large sites is your job, RatedPower is built for it and this review will not talk you out of it.
Where RatedPower Falls Short
The limitations are mostly fit and cost structure, not defects.
The addressable slice is narrow. It serves utility-scale development. If your company also does rooftop or C&I work, that portion of the book gets nothing from the contract while the contract cost is carried by the whole business.
Enterprise pricing needs enterprise volume. There is no small entry point to grow into. You commit at enterprise scale from day one, which means the risk of overbuying sits entirely with the buyer.
Automation output is a starting point, not a final design. Standardised generation is the strength. It is also the boundary. When a site demands unusual decisions, the generated package becomes an input that engineers then work on rather than the finished article.
It does not close deals. There is no consumer proposal motion here, and there was never meant to be. Teams that sell to a customer at the end of the process still need something else to sell with.
None of this makes RatedPower a bad product. It makes it a specific product. The wider field is covered in RatedPower alternatives, and the ground-mount comparison in PVcase alternatives.
What Most Buyers Get Wrong About RatedPower
They buy on demo speed and forget to count how often they will use it.
Here is the mechanism. The demo runs a parcel through the platform in minutes and produces a full document set. That is genuinely impressive, and it lands hardest on the person who spent last month waiting on one layout. The gap between that pain and the demo is what closes the contract.
Then the year runs. Origination forecast twenty sites. Eleven arrived. Four of them died on grid or land before engineering touched them. Three were repeats of a site already modelled. So the platform ran four new evaluations that mattered. The contract did not shrink to match.
Now watch where the engineering effort actually went. The four surviving projects moved past prefeasibility, and at that point the team stopped generating and started designing. Detailed electrical, civil, structural, and the drawing set that construction needs. The automated output seeded that work but did not complete it. The hours the platform was bought to remove reappeared downstream, one stage later.
The error is not buying RatedPower. It is sizing a fixed enterprise cost against a forecast pipeline rather than a historical one. Count the sites you screened last year, not the ones you hope to screen next year.

RatedPower vs SurgePV
These are not the same product and the table should make that obvious in both directions.
SurgePV is a browser-based solar design platform. It runs 8,760-hour simulation with module-level shading, mismatch, and string topology. It produces single-line diagrams and DWG export from the same model, and it includes a white-label proposal layer. One licence spans design, shading, and proposal, at $1,299 to $1,899 per user per year.
| Criterion | RatedPower (pvDesign) | SurgePV |
|---|---|---|
| Delivery | Cloud platform | Browser-based |
| Primary segment | Utility-scale developers, IPPs, large EPCs | Rooftop and C&I installers and EPCs |
| Automated utility-scale prefeasibility | Core strength | Not offered |
| Standardised engineering document generation | Core strength | Not the same automated document engine |
| Speed across many candidate sites | Very strong | Not the design goal |
| Hourly simulation | Part of the platform output | 8,760-hour, module-level |
| Module-level shading and mismatch | Not the marketed focus | Module-level shading, mismatch, string topology |
| Single-line diagram | Part of the generated document set | Produced from the same model |
| DWG export | Drawings generated by the platform | Produced from the same model |
| White-label customer proposal | Not offered | Included |
| Rooftop workflow | Not the product | Core workflow |
| Pricing | Enterprise subscription, quoted | $1,299 to $1,899 per user per year |
Read that honestly. RatedPower wins outright on automated utility-scale prefeasibility and standardised documentation at speed. SurgePV wins on the rooftop and C&I workflow, on module-level shading detail, on the proposal layer, and on price transparency. Choosing between them is choosing a segment, not choosing a winner.
When Automation Becomes a Constraint
Automation is a trade. You give up control over how the design is made in exchange for getting it made fast. At prefeasibility that trade is obviously correct. Nobody should hand-draw a layout for a parcel that may never be bought.
The trade inverts later. Once a project is real, the decisions that matter are the ones a generator cannot make for you. How the interconnection actually lands. What the geotechnical report forces on the foundations. A structural constraint on one corner of the site that no rule set anticipated.
At that point the standardised package becomes a well-organised input to detailed engineering rather than the deliverable. Teams that expected the platform to carry them to construction documents find the last stage is still human work. That is normal, and worth planning for. If detailed engineering capacity is the real bottleneck, our solar ground mount design and solar civil and structural engineering teams produce the construction-stage package that sits downstream of any prefeasibility tool. See the sample design pack or talk to our team.
Who Should Buy Which
Buy RatedPower if you are a developer, IPP or utility-scale EPC screening land at volume. You need many sites turned into comparable layouts and document sets quickly, your pipeline history supports an enterprise contract, and detailed engineering happens elsewhere. That is the job it was built for, and it does it well.
Buy SurgePV if your work is rooftop or C&I, or your team designs, simulates, and sells the same project. You need 8,760-hour module-level simulation, a single-line diagram, a DWG, and a branded proposal from one licence at a published price.
Buy both if you genuinely run two businesses under one roof. A development arm screening land and an installation arm delivering rooftop projects need different tools because they have different jobs.
Buy neither yet if you cannot state your last twelve months of site volume from records. Get that number first. It decides the answer.
The Verdict
Here is the opinionated part.
RatedPower is a very good product with a narrow and honest remit. It converts land into a credible utility-scale layout and document set faster than a human bench can, and for a developer screening sites that is worth real money. I would not argue against it for a team with the pipeline to feed it.
The problem is not the software. It is that the software gets bought by companies whose pipeline never reaches the volume that justifies an enterprise contract, on the strength of a demo that shows exactly the scenario the buyer wishes they had. The tool performs. The pipeline does not show up.
For most installers and EPCs, and for anyone whose work is rooftop or C&I, SurgePV is the better buy. One licence spanning design, shading, and proposal, at $1,299 to $1,899 per user per year, against an enterprise contract for automation you will not use at volume. That is a fit argument, not a quality argument, and it is the argument that decides most real purchases.
Conclusion
- RatedPower is genuinely strong at automated utility-scale prefeasibility and standardised engineering documentation. SurgePV does not replace it for that job and does not claim to.
- The honest issue is fit and cost structure. Enterprise pricing needs development-pipeline volume, and the automation that helps at screening constrains you once bespoke engineering starts.
- For rooftop and C&I teams, SurgePV is the better centre of the stack. One licence, published per-seat pricing, and drawings plus proposal from the same model.

FAQ
Is RatedPower worth the money? For a developer or IPP screening many sites a year, yes. The speed from parcel to layout and standardised document set removes real engineering hours at the stage where speed matters most. It becomes poor value when the actual pipeline is a handful of sites, because the enterprise contract does not scale down with usage.
What is RatedPower best at? Rapid automated prefeasibility on utility-scale sites. It generates a plant layout, an electrical design, and a consistent package of engineering documents and drawings quickly, and it makes iterating several configurations on the same site cheap. That combination is its strongest feature.
Can RatedPower be used for rooftop solar? No. It is aimed at utility-scale solar and increasingly storage, for developers, IPPs and large EPCs. It is not a rooftop tool and it is not a consumer proposal tool. Rooftop and C&I teams should evaluate platforms built for that workflow instead.
How much does RatedPower cost? It is sold as an enterprise subscription and quoted rather than published per seat. You go through a sales conversation to get a number. Budget for a fixed annual commitment and size it against your historical site volume rather than your forecast pipeline.
Does SurgePV replace RatedPower? Not for automated utility-scale prefeasibility. SurgePV does not offer that. It replaces RatedPower only in the sense that many companies evaluating RatedPower actually needed a rooftop and C&I design, shading, and proposal platform, which is what SurgePV is at $1,299 to $1,899 per user per year.
Should I choose RatedPower or SurgePV? Answer one question first. Is your deliverable a screening decision on land, or a designed and sold project on a roof? The first is RatedPower. The second is SurgePV. Teams that answer both usually need both, and teams that cannot answer clearly should count last year’s projects before signing anything.
