ANNUAL PERFORMANCE CALCULATIONS FOR EUROPE
SYSTEM WIND AND SNOW LOAD PRESSURE
Under the requirements of EN 12795-1 (European Standard) the type of collector used in these systems has been tested
(ITW 11COL1015) to 2000 Pa, the maximum pressure (positive and negative) limit of the test equipment. This value has
been used to determine the maximum permissible limits of wind load (v
m
) as 56.6 m/s (203.6 km/h) and snow load (s
k
) as 2
kN/m
2
.
Systems or collector only installations using these collectors are only to be installed where the maximum values of s
k
(snow load) and v
m
(mean wind velocity) for the specific geographical area and installation circumstances do not exceed
the European permissible limit of wind and snow load. Values of v
m
and s
k
for your area can be obtained by consulting the
local dealer, a qualified structural engineer or relevant authorities.
These collectors and systems are routinely used in Australian Cyclonic regions.
J SYSTEMS
Annual performance calculations of Solahart thermosiphon J systems with the J collector according to EN12976
SolarKeyMark Systems ITW Test Report 10SYS82-1 for the 151J (150 tank, 1 collector), 181J (180 tank, 1 collector),
302J (300 tank, 2 collectors) and 303J (300 tank, 3 collectors) systems.

Note: The over temperature protection tests have been carried out according to EN12976 with an irradiation higher than
20 MJ/m
2
/day. An over temperature protection device should be installed in the situation that irradiation this exposure
levels could be exceeded.
