An AI sales agent's solar tracker order, checked before it goes out

An AI sales agent prepares an order for a utility-scale solar project: an ARRAY Technologies tracker (DuraTrack, DuraTrack D2S, DuraTrack Hail XP, OmniTrack or STI H250), a foundation type, the site slope, soil and hail rating, the control features and a number of rows. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of how the trackers and foundations can be combined and returns a verdict, every reason and the figures it computed.

Scope: ARRAY Technologies solar trackers (DuraTrack family, OmniTrack, STI H250) with SkyLink, SmarTrack features and APA foundations: slope, rows, hail, soil, discount and stated total. See everything this validator covers

This validator models an order for the ARRAY Technologies tracker family, as described on arraytechinc.com, not just the scenarios shown underneath.

  • Trackers and limits — five tracker products, each modeled with its own limit on the north-south slope, the modules per row and the hail size it is rated for.
  • Controls — SkyLink, which applies to DuraTrack and OmniTrack, and the SmarTrack controller with its features (backtracking, diffuse, snow response, hail alert), which need the controller, with hail alert needing SkyLink.
  • Foundations and soil — ground screws, helical piles, C-piles and ballast, with driven foundations excluded in rocky soil, ballast limited to flat sites, and C-piles in rocky soil needing pre-drilling.
  • Discount and total — a discount of up to 8 percent, with a person approving above 3 percent, and the total a quote states against the total computed.
  • Approvals — a snow site without snow response, a small project, pre-drilling in rocky soil and a discount to approve go to a person.

Any ARRAY tracker order that touches these rules is in scope — not only the scenarios pictured here. Not covered: other tracker makers, fixed-tilt racking, engineering design and delivery. The prices in this validator are illustrative values chosen for the demonstration, not ARRAY prices, and the page shows no price table. The slope, row and hail limits, the foundation and soil rules, the discount limits and the approvals are modeled from comparable trackers and are not published by ARRAY.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Limits that differ by trackerOnly with care
Slope, modules per row and hail rating each differ by product, so each limit needs its own lookup and comparison rule, and a new product means editing all of them.		The product and the site values are fields of one request and are compared with the modeled limits on every call.
Controls that depend on other controlsOnly with care
Each SmarTrack feature needs the controller and hail alert needs SkyLink, so every dependency is its own rule, and a new feature means a new rule.		Every control is a field of the request, so each dependency is checked together with all the others.
Foundations that depend on slope and soilOnly with care
Ballast against slope and driven foundations against rocky soil are separate rules that each read a value from another line.		The foundation, slope and soil are in one request and checked together.
A stated total that must match the computed totalOnly with workarounds
The total is modules times a unit price built from several parts, so a separate rule is needed to recompute it and compare it with the stated figure.		The stated total is a field of the request and is compared with the computed total in the same pass.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases
Click to expand
    
Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the order; approval findings need a person to sign off; everything else is computed.

    
1The order has 0 modules; at least 1 module is needed.
2The order is 0 modules, below the 5,000-module project size; a person should confirm pricing.
3The site slope is 11 percent north-south; this tracker allows at most 10 percent.
4The rows have 121 modules; this tracker allows at most 120 per row.
5The design hail size is 25 tenths of an inch; this tracker is modeled for at most 20.
6SkyLink applies to DuraTrack and OmniTrack trackers; it is not quoted on this product.
7A SmarTrack feature is quoted without the SmarTrack controller.
8Hail Alert Response needs a SkyLink-controlled tracker.
9Ballast foundations are limited to 5 percent slope; the site is 6 percent.
10Ground screws and helical piles cannot be installed in rocky soil.
11C-piles in rocky soil need pre-drilling; a person should confirm the foundation plan.
12The site has snow loading but Automated Snow Response is not quoted; a person should confirm.
13A 4 percent discount needs sales-management approval.
14A 9 percent discount is above the 8 percent maximum.
15The quote states USD 613,000 in total; the order lines add up to USD 612,000.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for a utility-scale solar project: an ARRAY Technologies tracker (DuraTrack, DuraTrack D2S, DuraTrack Hail XP, OmniTrack or STI H250), a foundation type, the site slope, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of how the trackers and foundations can be combined and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 80 rows of 90 modules on DuraTrack trackers with ballast foundations, at a site with a 12 percent north-south slope and standard soil. The design hail size is 2.5 inches. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with five findings and one approval, all in one answer. The site slope is 12 percent north-south; this tracker allows at most 10 percent. The design hail size is 25 tenths of an inch; this tracker is modeled for at most 20. A SmarTrack feature is quoted without the SmarTrack controller. The other two are on screen.
    6. 
      
  6. The validator returned five blocking findings and one approval in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the order are checked against each other.
    7. 
      
  7. What this shows: for limits that differ by tracker, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the tracker to OmniTrack, the foundation to ground screw and the design hail size to 1.5. It sets the SmarTrack controller to yes. Two more changes are on screen.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All six earlier findings are cleared.
    13. 
      
  13. Six problems caught in one call, fixed in one pass, and a clean order. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
