Figures are facts read from the publishers' own documents. The documents themselves, their text and design, stay under each publisher's terms; follow the source links for those.
How this measure is built
- Definition
- Total cumulative solar electricity generating capacity.
- Measure
- One slice of Electricity capacity ( basis: cumulative, form: level, segment: solar ) . Maximum electrical output capacity of power installations. Region and period are columns on every record, not slices.
- Limitations
- 2 figures are projections, drawn dashed and labelled in the table. Values are shown as published; StatOrigin does not revise, fill gaps or convert currencies.
- Verification
- Each value, unit, period and place was checked against its source evidence before publication. See the methodology and the corrections process.
