Solar Country Notes
Latvia's total solar radiation varies between 900 and 1 100 kWh/m2/yr; although the amount of sunshine the country receives is only about 1 200 h/yr, solar power is being utilised to good effect.
PV systems have been installed in lighthouses and lightships and in some small demonstration projects, as at Riga Technical College.
Solar collectors have been installed at a number of schools and other locations. The Danish-financed solar thermal project at Aizkraukle Secondary School Nr. 2, completed in 2002 with 155 m2 of collectors, was at the time the largest such project in the Baltic States. The total glazed area of solar thermal collectors in operation in 2005 was 2 650 m2, giving an output capacity of about 2 MWt.
