Layer: Solar GHI Zones · Nepal Energy Wiki

Summary

This explorer layer shows coarse solar-resource zones based on GHI interpretation, giving the map a broad resource-geography layer rather than parcel-level siting output.

Explorer label: Solar resource zones
Layer group: Solar layers
Feature count: 6

Coarse solar resource zones. These are strategic zones, not parcel-level siting decisions.

What It Represents

This layer maps broad solar resource geography using GHI interpretation. It places solar in Nepal's spatial energy story, especially the Terai and high-insolation zones that can complement hydro seasonality.

How To Read It

Use it with solar plants, solar suitability, and hydropower seasonality. The question is not simply where sun exists, but where solar can be built quickly enough to help winter deficits and reduce over-dependence on hydro timing.

Coverage / Method

The layer is a coarse map-layer interpretation of solar GHI zones exposed through the explorer map inventory. It covers broad resource zones and is intended to be read alongside the related solar resource data page, solar plant layer, and suitability layer.

Caveats

GHI zones are not project-ready siting. Land access, grid connection, slope, social constraints, and procurement design matter as much as resource quality.
