The incident solar radiation is reflected by the CPC reflector onto the absorber surface of the evacuated tubes

where it is converted into heat. The high vacuum in the tubes combined with the highly selective coating on the

absorber prevents the heat from escaping into the environment. The heat is transported away from the collector

using a suitable heat transfer medium and by means of so-called heat exchangers inside the vacuum tubes and

the tube register connected to them.

The collector output is calculated based on the collector efficiency ( ) depending on the strength of the

irradiation (G*) and the aperture area per collector unit (A). It provides information on the thermal output of

the collector at a specific irradiation strength. The following equation is used to calculate the collector output:

with:

If the difference between the collector temperature and the ambient temperature ( ) is zero,

the collector has zero heat loss to the surrounding air and the efficiency is maximum;

this is known as optical efficiency .

Part of the solar irradiation (G*) which strikes the collectors is lost due to reflection and absorption.

The optical efficiency takes these losses into consideration.

When the collectors heat up, they dissipate heat to the surrounding area via conduction,

radiation and convection. The heat transmission coefficient a1 and a2 incorporate these losses.

The almost horizontal power curves mean that CPC collectors generate high outputs even at great temperature

differences between the collector temperature and the ambient temperature, in contrast to flat plate collectors.

In general, less solar irradiation is available for use as solar energy (for water heating and heating support) in the

six winter months and in transitional periods (e.g. 400 W/m2). The temperature differences between the collector

temperature and the ambient temperature are also very high due to the low temperatures outside.

The following tables (source: ITW test report number 06COL513) give an exact overview of how the collector

output changes depending on the radiation strength and temperature difference. The values specified are for

vertical irradiation.

An average throughput of 30 40 l/h per m2 of aperture area (approx. 0.5 0.7 l/min per m2) can be assumed

when selecting the piping dimensions. We recommend low-flow operation for large-scale solar energy systems,

as the specific flow rate can be reduced to 12 18 l/h m2 (approx. 0.2 0.3 l/min per m2). In order to keep piping

work to a minimum, we recommend that you connect max. 9.0 m2 (high-flow) and 15 m2 (low-flow) of collector

aperture area in series. In order to minimise the pressure loss due to the solar energy system piping, the flow

speed in the copper piping should not exceed 1 m/s. We recommend flow speeds of between 0.3 and 0.5 m/s.

The cross sections should be dimensioned in accordance with throughput and speed as in a standard heating

system. We recommend that you use standard copper piping and gunmetal fittings when installing the collectors.

The connection points of the pipes should be brazed or connected using olive connections due to the high

stagnation temperatures. No galvanised pipes, galvanised fittings or graphite seals may be used. Hemp may

only be used in conjunction with pressure and temperature resistant sealant. The components used must be

resistant to the heat transfer medium. The thermal insulation of pipes outdoors must be temperature and UV

Calculation basis for determining the expansion tank size

The formulae specified below assume that a 6 bar safety valve is used. For precise calculation of the expansion

tank volume, the content volumes of the following system components must first be determined, in order to

then calculate the tank volume using the formula below.

Formula: Vnom ( Vsystem 0.1 + Vvapour 1.25 ) 4.8

Vnom = nominal volume of the expansion tank

Vsystem = content of the entire solar circuit

Vvapour = content of the collectors and pipes which are in the vapour zone

Example: determining the individual volumes:

Based on: 2 CPC 12 OEM / INOX collectors

Pipework: Cu 15 mm, 2 x 15 m in length

Static height H: 9 m

Contents of the storage tank heat exchanger and the solar station: e.g. 6.4 l

Pipelines in the vapour zone: 15 mm Cu pipes, 2 x 2 m

The individual capacities of the system components can be ascertained from the respective data tables in

the product description. The sizes of the standard Cu pipes and the contents of the CPC tube collectors are

specified on the following page.

Vsystem = Contents of: heat exchanger of the storage tank + pipelines + collectors

= 6.4 l + 30 m 0.133 l/m + 2 1.6 l = 13.59 l

Pipes above or at the same height as the collector manifold (or the lowest manifold if there are several collectors

above each other) can be filled with vapour if the solar energy system comes to a standstill. Thus, the contents

of the affected pipes and the collectors are included in the vapour volume Vvapour.

Vvapour = 2 1.6 l + 4 m 0.133 l/m = 3.73 l

(Contents of 2 x CPC 12 OEM / INOX + 4 m Cu 15 mm piping)

Calculation of the expansion tank size:

Vnom ( Vsystem 0.1 + Vvapour 1.25 ) 4.8

Vnom (13.59 l 0.1 + 3.73 l 1.25 ) 4.8 = 28.90 l

Selected expansion tank: 35 l

Sizing the expansion tank


All expansion tanks within SOLFEX Energy Systems Prestige Solar Thermal Packs are sized based

on a pipe work length of a maximum 25m and pipe work diameter DN16.

please refer to the below guidlines or consult the SOLFEX Energy Systems technical team.

For systems requiring pipe work lengths greater than 25m or pipe work diameters greater than DN16,

For wall installations, 4 suitable

bolts or screws of sufficient length

and thickness are to be used for

each angle frame. Here, the com-

bined weight of the collector and

angle frames, as well as stress

from snow and wind must be

taken into account. The offset

corner of each angle frame is to

point upwards.

On cavity wall masonry, the wall

plugs are to be inserted in the

load-bearing wall, or threaded

bolts are to be used.

If the angle frame is mounted on

a facing skin which is not very

stable, it should be underlaid with

suitable slabs, which transfer the

exerted forces onto the masonry

in such a manner that they are

distributed over a large area.

1. Connect the square tubes,

straight (pos.1) and angled

Attach the wall plugs (pos.4)

and angle frames (pos.2) to the

bolts (pos.5) or other suitable

bolts or screws. The alignment

of the angle frames is to be

assessed with the use of a

line guide on the lower edges

of the frames.

The system may not be filled if the collectors were previously or are currently exposed to direct

sun radiation.

For flushing and filling the solar system the antifreeze Tyfocor LS is exclusively certified.

In case of neglect, all warranty claims expire.

1. Before filling the system, check the admission pressure of the expansion tank and correct, if necessary.

2. Check whether all slide valves, flow control valves, check valves, or

gravity brakes are in their opened position.

3. Fill the system through the filling armature with antifreeze Tyfocor LS

(finished mixture).

Danger!

Whenever replacing defective or damaged tubes, gloves and safety glasses

must be worn.

1. Carefully remove glass shards, without damaging the CPC reflector surface.

2. Remove residual glass from the manifold.

3. Then remove the tube retainer.

Caution: a risk of cracking arises if the tube is bent by more than 20.

1. Ensure that the location of the silicone ring (pos.4) in the manifold is clean.

2. Coat the upper tube end with grease paste or soap, so that the tube can be easily pushed through the

silicone ring in the manifold.

3. Install the new tube in a manner corresponding to the manner in which the defective tube was removed.

While rotating the tube slightly, push it through the silicone ring into the manifold.

4. Place the tube retainer on the end of the tube. Grip the end of the reflector contour with the tube retainer

raised, push the tube retainer between the two notches on the aluminium frame, push downwards and into

the groove in the frame.

5. Pull the tube downwards into the tube retainer as far as it will go.

If one of the collectors reflector plates is damaged, it can easily be replaced.

Danger!

Wear gloves and safety glasses whenever mounting or dismounting tubes.

Caution!

Wear gloves and safety glasses when exchanging reflector plates.

Injuries through reflector edges and hot collector parts are thus to be avoided.

1. Dismount the tubes above the reflector plate that is to be replaced, as described in point 5.4. Store the tubes

safely while the reflector is being replaced so as to avoid damaging them.

2. Pull down on and remove the damaged reflector under the tubes.

3. Carefully lift up all meander tubes that are present above the reflector that is to be replaced. A batten or

something similar can be used as an aid when lifting up the meander tubes. Slide the batten diagonally

under the meander tubes.

4. Slide the new reflector under the meander tubes with the notches facing the manifold. The notches must be

clamped onto the top of the manifold.

5. Mount the tubes again, as described in point 5.5.
