Efficiency (ηcol) (**)
(*) Tested according to EN 12975, referred to a 33.3% water-
glycol mix, flow rate of 170 l/h (CSV 25 R) - 240 l/h (CSV 25
R), and irradiation G = 800W/m
Tm = (Coll._inlet _temp.+Coll._outlet_temp.)/2
T*m = (Tm-T_ambient)/G
(**) Calculated with a temperature difference of 40K between
the solar collector and the surrounding air, and with total
solar radiation of 1000 W/m
9
Minimum recommended slope is 15° (to ensure efficient self-cleaning and minimise snow pressure).
Installations in locations liable to frequent snow and hail, and installations on flat roofs in locations subject to strong winds
are not recommended (see "Static load" on page 11).
