Complete Solar Analysis: Tbilisi, Georgia
Solar Overview
Tbilisi receives an average of 1,953 sun hours per year, with peak solar production during August. This latitude (41.72°) offers a balanced solar profile with noticeable but not extreme seasonal differences in energy generation. The moderate solar resource in Tbilisi requires optimization of system design to maximize energy production and economic returns.
Geographic Impact
The coordinates 41.7151°N, 44.8271°E define Tbilisi's position and directly influence its solar energy characteristics. At 41.72°, the balance between seasonal variation and consistent production makes this an ideal latitude for fixed solar installations.
Rating Methodology
The "Average" classification reflects Tbilisi's solar resource quality, considering its 1,953 annual sun hours and 11.2°C average ambient temperature. The cool environment benefits panel efficiency, with lower temperatures offsetting reduced irradiation during shorter winter days. These conditions make solar economically viable, especially when electricity costs are high or incentives reduce initial investment.
Understanding the Data
The following chart shows how solar energy varies month-to-month in Tbilisi. Summer months (June–August) account for approximately 42% of annual solar irradiation, while winter months contribute around 16%. This distribution pattern helps inform decisions about fixed versus tracking systems and optimal capacity design.
