The considered countries are characterized by poor actinometric conditions and relatively low tariffs for traditional energy resources. At the same time, Belarus. . In 2024, Belarus solar power capacity saw a decline with the installation of only 0. 265 GW, marking a growth rate of -2. 15 % of the Belarus's energy mix.
