2. GENERAL DESCRIPTION
The accessory you just bought, if used according to the instructions given
in this manual, guarantees accurate and reliable measurements thanks to
the stability of the used cell and to the possibility of compensating the
effects of temperature on the cell itself through the in-built temperature
sensors.
1. FUNCTIONS OF ACCESSORY HT305
Accessory HT305 measures irradiance only when connected to the
remote unit SOLAR03 through an in-built monocrystalline cell, and
can be used with two different kinds of modules, built according two
different technologies:
➢ MONOFACIAL modules  measurement of irradiance only on the
module's front (F)
➢ BIFACIAL modules  measurement of irradiance both on the
module's front (F) and on the module's back (obtained by reflection
from the surrounding environment) by dividing the high back part (BH
= BackHigh) and the low back part (BL = BackLow). In this case, it
is necessary to use three HT305 cells
Irradiance can only be measured by connecting accessory
HT305 to the remote unit SOLAR03, which automatically detects the
measuring sensitivity after connection
