COLLECTOR CASE
The collector case is produced from aluminium by Solimpeks solar energy systems. The aluminium used as raw
material is 6603-60 (AlMgSi05) (AA-USA) . The collector case is produced with a frame which is a user friendly both in
terms of mounting and dismounting the system. Wall thicknesses both for the case and frame are all according to DIN
EN 12975 -1 and 2. Collector case is made of aluminium which is electrostaticly painted with Ral 9005 matt black
powder paint and then oven baked. The use of this tecnique ensures the system is highly protected against all natural
conditions. Also taken into consideration is the possible thermal expansions that could occur on the glass, hence the
glass is set up with an optional space during casing and the collectors are produced to be able to work properly in all
regions of the world.

COLLECTOR INSULATION
Heat loss can occur on the bottom and the sides and this can be decreased by using insulation material.
Insulation material is designed to be resistant against high temperatures of up to 650 C within the collector.
The insulation material must be of a high quality in order to withstand these high temperatures. In addition,
this insulation material with its high density does not produce gas, thus the transparent
cover’s solar
conductivity is not affected.
Mineral rock wool, a high quality insulation material, is used inside the collector which touches the absorber
sheet and also has an endurance against high temperatures. The insulation material rock wool is also water-
resistant against water which could accumulate in the collector.
TRANSPARENT COVER
– THE GLASS
The glass used in Solimpeks collectors has the thickness of 4mm and has the tolerance of
0,2mm. The
density of the glass is 2,5 gr/cm2 . To increase the solar conductivity of the glass, the iron oxide level is
lowered
.
The prismatic shape of the glass brakes the solar rays which come inclined in the morning and
evening, and makes the solar rays vertical with this prismatic design, this ensures maximum efficiency. The
other important characteristic of the glass is has high endurance.
During the transportation and mounting
process, to prevent the highly risk of breakage, Solimpeks uses tempered glass which can also be described
as safety glass. This type of tempered glass is very strong and brakes very rarely. Should the tempered glass
brake, it brakes into small pieces thus reducing the risk of harm
.
