Russia
is located between 41 and 82 degrees north latitude,
and solar radiation levels on its territory vary
considerably. According to estimates, the average
solar radiation in the remote northern regions is
810 kWh/m2 per year whereas in the southern areas
it is more than 1400 kWh/m2 per year.
Solar radiation levels also exhibit great seasonal
variations. For example, at latitude of 55 degrees
solar radiation is 1.69 kWh/m2 per day in January,
and 11.41 kWh/m2 per day in July. Gross solar energy
potential is estimated at 2,300,000 mtce, technical
potential at 2,300 mtce and economic at 12.5 mtce.
Solar energy potential is greatest in the south-west
(North Caucasus, the Black and Caspian Sea regions)
and in Southern Siberia and the Far East. Regions
with significant solar resources include: Kalmykia,
Stavropol, Rostov, Krasnodar, Volgograd, Astrakhan,
and other regions in the south-west, as well as
Altay, Maritime, Chita, Buryatia and other regions
in the south-east. In some parts of Western and
Eastern Siberia and on the Far East the annual solar
radiation is 1300 kWh/m2 esceeding levels in the
southern regions of Russia.
For instance, in Irkutsk (52 degrees north latitude)
incoming solar energy reaches 1340 kWh/m2, and in
the Republic of Yakutia-Sakha (62 degrees north
latitude) the figure is 1290 kWh/m2.
