Before construction
Explore better utility-scale solar designs before construction.
Before the layout becomes infrastructure, its geometry is still a choice. AridMetrics explores how spacing, tracker configuration and site constraints define the design space—and how those choices should be compared through physical modelling.
Design methodology under development
Define what can change
Design variables
A greenfield study begins with permitted design choices, not an assumed optimum. Pitch is row-axis spacing; for regular parallel rows, GCR relates collector width to pitch. These quantities must be defined consistently rather than varied as unrelated parameters.
- Layout A
Narrower pitch
Higher GCR - Layout B
Intermediate pitch
Intermediate GCR - Layout C
Wider pitch
Lower GCR
- Layout and spacing
- Compare row placement, pitch and resulting ground coverage.
- Tracker configuration
- Define axis geometry, hardware choices and maximum rotation limits.
- Site boundary
- Respect land-use limits, access requirements and relevant physical constraints.
Connected trade-offs
Spacing changes more than the shadow.
Sun position, row spacing and tracker orientation jointly shape which surfaces receive direct light and when neighbouring rows cast shade. The same layout also determines how collectors occupy the available land and how the chosen tracking strategy interacts with nearby rows.
Wider spacing is therefore not a universal design answer. Comparisons need a stated land boundary, equipment assumptions and a common basis for reporting performance. A change that favours one consideration may restrict another; the point is to make that trade-off inspectable.
- Direct / beam
- Solar position, orientation and row shading
- Sky diffuse
- Visible sky and neighbouring-row restrictions
- Ground reflected
- Ground reflectance and ground-view relationships
More than one objective
Define the trade-off before searching for a solution.
Electrical performance is important, but it need not be the only design consideration. Objectives should be named, their meaning documented and their constraints kept visible. An optimiser cannot decide which trade-offs matter on behalf of the project.
- Energy performance
- Electrical response
- Land utilization
- Spatial requirements
- Environmental / land-surface considerations
- Research objectives
- 01Performance and geometry
- Examine irradiance reception, shading and the energy response of feasible layouts.
- 02Land and operation
- Consider land utilisation, equipment limits and the feasibility of later operation.
- 03Environmental questions
- Investigate land-surface trade-offs without presenting them as proven ecological or climate benefits.
A reviewable design process
From site conditions to a defensible comparison.
A useful design study preserves the path from its inputs to its conclusion. Each stage should retain the assumptions and constraints that the next stage inherits. Optimisation explores this defined space; validation and review determine what the outcome can support.
- 01
Site conditions
Establish the physical context and input quality.
- 02
Define design space
Set variables, boundaries and equipment constraints.
- 03
Physical modelling
Represent geometry, irradiance and energy response.
- 04
Scenario comparison
Use consistent assumptions and reporting boundaries.
- 05
Optimisation
Search only among feasible alternatives.
- 06
Validation / review
Examine evidence, sensitivity and remaining uncertainty.
After construction
The design space becomes an operating boundary.
Once a plant is built, pitch, GCR, installed row geometry and land footprint are fixed for an operational study. A tracker command does not change the spacing between rows or replace the installed hardware. Physical modifications would be a separate design decision.
The operating question is narrower: which tracker positions and strategies are feasible within that infrastructure? Keeping this boundary explicit prevents a promising design scenario from being misrepresented as an available improvement to an existing plant.
