Peak sun hours a day on flat ground. Each dot is one place.
The sunniest place in Georgia is Akhaltsikhe (Samtskhe-Javakheti) with 3.98 peak sun hours a day on flat ground; the least sunny is Batumi with 3.77. A 1 kWp array at its best angle makes from 1,306 kWh a year in Batumi to 1,428 kWh in Akhaltsikhe — 1,363 kWh on average.
The best year-round tilt runs from 34° in Batumi to 36° in Kutaisi. Off-grid systems are sized for the darkest month and do better steeper, at 66° on average: at 70° that month brings 2.25 kWh per kWp a day in Stantsiya Novyy Afon and 3.04 kWh in Akhaltsikhe.
