Methodology

Methodology

This page explains how Solar Rack Wiki compiles its data so that readers can judge and reuse it.

Units and scope

  • Capacity is reported in MWdc or GWdc with the basis stated. Shipments, installations, orders and commissioned capacity are reported separately and never used interchangeably.
  • Material prices are quoted in USD per tonne with the source and pricing date. Company financials quoted in CNY are shown alongside a USD conversion with the exchange-rate date.
  • Loads, coating thickness, wind speed and torque use SI units: kN/m2, micrometres, m/s and N·m.

Trade measures

We distinguish between Section 232 national-security tariffs, Section 301 tariffs, antidumping (AD) and countervailing (CVD) duties, safeguard measures, carbon border mechanisms and import prohibitions. Each record states the jurisdiction, authority, product scope, whether trackers or racking are actually covered, the rate type and the procedural status (petition, initiation, preliminary, final, in force, review or expired). Rates are taken from official gazettes, not media summaries.

Verification and maintenance

Every database record carries a last_verified date and links to its primary sources. Wiki entries, vendor profiles and trade cases are reviewed at least quarterly. Datasets may be downloaded as CSV; please cite Solar Rack Wiki with the access date.
