Data as of 10 October 2026 · version 2026-10-11.

Assumptions and notes

1. N1Solar figures are Ember estimates of all solar added in each year (utility-scale, distributed and off-grid together), not distributed solar alone. Ember derives them from Chinese panel export data, assuming 73% of exports are installed about six months after export, adjusted for imports from other countries, re-exports, domestic manufacturing and, where available, official data.
2. N22026 values are Ember's estimate for the full year. Small-market estimates are uncertain and can swing sharply from year to year.
3. N3Access rates are World Bank 2024 data (database updated 8 October 2026). People without electricity is a DERCA calculation: (100% − access rate) × 2024 population. It may differ slightly from Tracking SDG7 figures.
4. N4Firm outages: share of firms reporting electrical outages in the World Bank Enterprise Survey. Survey years differ by country and are shown with each value.
5. N5Rules reflect a desk review of public sources to 10 October 2026. “None found” means DERCA could not locate a rule in the sources reviewed, not that none exists. Countries reviewed in detail in the full report are marked; others received a shorter scan, with confidence shown per field.
6. N6CrossBoundary Energy regulatory stages (January 2024, Namibia updated August 2025) are shown only where CrossBoundary assigned one.
7. N7DERCA does not rank countries. Data are provided for information only, and DERCA accepts no liability for decisions based on them. Corrections are welcome and will be logged.

“None found” means we could not locate a rule in public sources reviewed to 10 October 2026, not that one cannot exist.
