Data & Methodology

Data & Methodology

How Solardash is built — the static-first model, every dataset's provenance, what's modelled, and how to refresh it.

As of 1 Apr 2026

Methodology

Static-first — no live database.

Solardash is static-first. Offline pipelines (tsx scripts) read human-maintained feeds in manual-data/, derive metrics, and write committed JSON snapshots. Pages are prerendered (force-static) and read those snapshots — there is no runtime database or client-side fetching, so every figure is reproducible and versioned in git.

Confidence legend

  • HighOfficial / disclosed — MNRE, CEA, SECI, or company filings.
  • MediumPublic data with Solardash aggregation / derivation.
  • ModelledSolardash estimate or model (splits, forward curves, attribution).

Data provenance

Every committed snapshot — auto-generated from the live data layer.

Modelled metrics

What's estimated, how, and where to refine it.

Quarterly cell production

Modelled

Each producer's FY26E annual output is split across quarters with a fixed ramp [0.22, 0.24, 0.26, 0.28]; real (player, quarter) actuals override the modelled split.

Refine in manual-data/manufacturing/cell-production-quarterly-override.csv

IPP funnel splits

Modelled

Per-developer operational / under-construction / pipeline and the tech mix are partly modelled from investor disclosures.

Refine in manual-data/developers/developers.csv

BESS cost curve (forward)

Modelled

The 2026 and 2030 points on the BESS $/kWh curve are modelled projections; historical points are sourced.

Refine in manual-data/policy/bess-cost-curve.csv

Update workflow

Edit a feed, rebuild, commit.

  1. Edit the relevant feed under manual-data/<section>/….
  2. Run npm run data:build (or :monthly / :quarterly) to regenerate the committed snapshots deterministically.
  3. Commit the changed feed and snapshot. See docs/ARCHITECTURE.md §9 for the full recipe.
