What this edition demonstrates

Capacity × irradiation × performance ratio; crop and PV yield ratios summed.

Scenario arithmetic is not measured crop response or evidence of a causal benefit.

The public website hosts a read-only synthetic projection. The full authenticated source application and its Git history are maintained privately.

All fixtures are fictional. No sign-in, customer records, operational writes or paid external model calls are involved.

MATHEMATICAL SPECIFICATION & UNITS

Governing Equations, Inputs, Outputs & Dimensional Conventions

Solstice Field Lab executes deterministic client-side calculations in the browser. Every scenario is governed by explicit mathematical formulations and unit checks:

E_annual (kWh) = Capacity (kW) × Irradiance (kWh/m²) × PR; Energy_per_ha = E_annual / Area (ha); PV_Yield_Ratio = Energy_per_ha / Ref_PV_Yield (kWh/ha); LER = Crop_Yield_Ratio + PV_Yield_Ratio

Declared Units & Arithmetic Conventions: PV capacity in kW; annual irradiance in kWh/m²/yr; performance ratio (PR) dimensionless (0–1); field area in hectares (ha); energy yield in kWh/yr and kWh/ha/yr; Land Equivalent Ratio (LER) dimensionless.

Scope & Operational Boundary: Agrivoltaic energy and land-equivalent-ratio scenario calculations. Not developer tooling or measured agronomic/field-yield validation.

REPRODUCIBLE WORKED EXAMPLE & BENCHMARK TABLE

Verified Case Study & Held-Out Reference Table

Worked Verification Case: Case 1 (4 ha shared field, 100 kW agrivoltaic array, 35% coverage, irradiance = 1,400 kWh/m², PR = 0.80, crop yield ratio = 0.70, reference monoculture PV yield = 140,000 kWh/ha): Annual PV energy = 100 × 1,400 × 0.80 = 112,000 kWh (28,000 kWh/ha). PV relative yield = 28,000 / 140,000 = 0.20. Combined Land Equivalent Ratio (LER) = 0.70 + 0.20 = 0.90.

PROCEDURAL USAGE GUIDE

How to Use Solstice Field Lab in 3 Reproducible Steps

Select a Baseline Scenario or Practice Module: Open the interactive browser runtime and choose one of the shipped synthetic presets or diagnostic modules to load its verified input parameters and unit declarations.
Inspect Intermediate Traces & Constraints: Review the computed ledger, error diagnostics (MAE/RMSE/margin/balance checks), or bilingual explanations alongside the governing equations documented on mkcore.co.technology/methodology/.
Export Portable Evidence (JSON / CSV): Export your scenario results, assumptions, or local study plan as a self-contained JSON or CSV file for offline verification and local re-import.

FREQUENTLY ASKED QUESTIONS

Methodological & Boundary FAQs

What mathematical model and units does Solstice Field Lab use?

Solstice Field Lab applies E_annual (kWh) = Capacity (kW) × Irradiance (kWh/m²) × PR; Energy_per_ha = E_annual / Area (ha); PV_Yield_Ratio = Energy_per_ha / Ref_PV_Yield (kWh/ha); LER = Crop_Yield_Ratio + PV_Yield_Ratio. Units: PV capacity in kW; annual irradiance in kWh/m²/yr; performance ratio (PR) dimensionless (0–1); field area in hectares (ha); energy yield in kWh/yr and kWh/ha/yr; Land Equivalent Ratio (LER) dimensionless.

What are the operational boundaries and limitations of Solstice Field Lab?

Agrivoltaic energy and land-equivalent-ratio scenario calculations. Not developer tooling or measured agronomic/field-yield validation. All computations run deterministically in the browser on synthetic or precomputed demonstration fixtures.

How can I reproduce the benchmark results in Solstice Field Lab?

Open the interactive browser workspace at ./run/, select Case 1 to inspect the worked result (Case 1 (4 ha shared field, 100 kW agrivoltaic array, 35% coverage, irradiance = 1,400 kWh/m², PR = 0.80, crop yield ratio = 0.70, reference monoculture PV yield = 140,000 kWh/ha): Annual PV energy = 100 × 1,400 × 0.80 = 112,000 kWh (28,000 kWh/ha). PV relative yield = 28,000 / 140,000 = 0.20. Combined Land Equivalent Ratio (LER) = 0.70 + 0.20 = 0.90.), and export the JSON or CSV evidence ledger.
