GRAPHS & STATISTICS
Annual thermal energy production or “energy crop” depends on:
Available solar radiation
Environmental temperature
Thermal technology employed
In Austria, annual energy crop is:
350 KW hr / Sq Meter … with flat glass collectors
300 KW hr / Sq Meter … with plastic uncovered collectors
550 KW hr / Sq Meter … with evacuated crystal collectors
Globally 140 Million sq. meters of thermal collectors are in operation
Increasing 10 Million sq. meters per year.
Worldwide installed capacity = 100 GW
China produces 35 GW with only 22 M sq. meters (15.7%) of evacuated
crystal collectors.
US, Canada & Australia produce 18 GW with absorbed non covered plastic
collectors
Europe produces 10 GW with flat glass and evacuated tubes
Germany, Greece and Austria are the leaders in Europe
Japan produces 9 GW with flat glass and evacuated tubes
