Jamaica is sunny, yes. That does not make every roof the same.

One guide for the connected market, with separate Kingston and St Andrew figures kept visible.

From Portmore and Spanish Town to Linstead and Ewarton, the map shows a useful local spread.

A clear divide between the southern plain and higher terrain in upper Clarendon.

Close to the national average, with roof access and hill shade often more important than location.

Excellent southern and western output, with salt, wind and oversizing still worth checking.

Negril and the southern coast lead, while inland and eastern areas are more moderate.

A relatively tight geographic range makes roof shade and coastal durability decisive.

The northern coastal belt is stronger; urban shade and multi-storey access add local constraints.

Coastal output is stronger than the steeper, more heavily vegetated interior.

The west is stronger, while vegetation and interior terrain shape many real roofs.

The north-coast edge performs better than much of the cloudier, hillier interior.

A stronger coastal strip and much lower mountain cells make an islandwide average misleading.

Strong southern coastal output falls toward the Blue Mountain slopes and valleys.
