SOLE S.A. – Solar Collectors – Installation Manual

1. Presentation

The present document demonstrates detailed installation instructions for the solar

collectors using the support frames and accessories included in the supply.

Before proceeding with the installation of the collectors, read these instructions and

make sure you have understood. If you have questions about the materials or on the

assembly process described in this document, contact your supplier via telephone,

fax or e-mail. Improper installation of the collectors may cause an unsatisfactory

operation of the solar system, compromising its durability and even be dangerous for

the people or the goods.

The instructions of this document do not exempt in any way the compliance with

existing regulations and provisions of technical and administrative application at the

place where the facility is located.

The installation of solar collectors without following the instructions in this document

and / or regulations will invalidate the warranty of the product.

The installer will check before starting the installation that he has all the necessary

parts and all the security measures have been taken in order to carry out the

installation safely. The installer must use protective gloves to avoid any risk of burns

or cuts during handling of collectors or its support frame.

2. Parts Included

The supply consists of:

One or more solar collectors

One or more support frames

Two or more fitting and connection (except for a single collector)

2.1. Solar Collectors

The solar collectors are supplied individually packaged in carton boxes. The collector

model is indicated on the outside of each box. Depending on the number of units

ordered, collectors can be supplied palletised in groups of up to 10 units. Collectors

should always be during transport and storage placed with the glass facing on top,

otherwise there is danger of water entering in the collectors from the ventilation holes

at the back of the collector.

The main technical characteristics of the collectors are indicated below (figure no. 1)

Figure 1. Characteristics of solar collector

SOLE S.A. – Solar Collectors – Installation Manual

The manufacturing of the solar collector follow strict quality criteria and is certified by

ISO 9001:2008.

The collector is certified by the authorized national bodies of different countries and

tested by several accredited laboratories (TUV, INETI, CSTB, Demokritos,). Our

collectors are Solar Keymark, CSTBat and SRCC. Certified.

The figure below shows the characteristics of instantaneous energy efficiency curve

of solar collector.

2.2. Support Frame

There are two sets of support frames for a single collector (EST1) or for two

collectors (EST2).

Depending on the bank of solar collectors chosen, the appropriate number of support

frames will be provided for one or two collectors. Table 1 shows the sets of support

frames necessary for different banks of solar collectors.

Table 1. The support frames and the connections provided depend on the number of

collectors per bank

SOLE S.A. – Solar Collectors – Installation Manual

The support frames sets are composed of elements that are shown in Figures 3 and 4.

Figure 3. Support frame components EST1 for a single solar collector

Figure 4. Support frame components EST2 for two solar collectors

The support frames allow the installation of the solar collectors with different

inclinations (45, 40, 35 or 30 degrees) using the same profiles and accessories, by

choosing properly the fixing holes.

SOLE S.A. – Solar Collectors – Installation Manual

2.3. Connectors

The connectors supplied are conical-type compression unions with metal ring and

allow the connection of two or more solar collectors in a bank, joining the top and

bottom of the collectors.

This way, the collectors are hydraulically connected between them in parallel.

The number of connections provided is determined by the number of collectors in the

bank, according to Table 1 above.

Figure5. Connections

3. Placement of the Collectors

The choice of location, inclination and orientation of the solar collectors has to be

determined at the design stage of the installation. The installation of the solar

collectors in the building should be carried out respecting the instructions of the

person in charge of the project, who should have taken into consideration the effect

of the orientation, inclination and possible shadows in the calculation of benefits of

the solar system.

Particular attention should be paid to the minimum distance maintained between two

rows of solar collectors or between an obstacle in front of a group of solar collectors

and them. During the calculation of this distance one should take into consideration

the latitude of the place, the inclination of the terrain and the period of use of the

facility. Failure to have a more detailed specification by the designer of the facility,

the distance should not be less than that shown in Figure 6.

At the time of its installation, the solar collectors should be stored in a compound

covered and kept in their original packaging. During the assembly phase, avoid

SOLE S.A. – Solar Collectors – Installation Manual

keeping the solar collectors outdoors with the cover glass facing down on wet

surfaces, in order to prevent entry of humidity or water in the rear of the collector.

Figure 6. Distance needed in order to avoid shadows on collectors.

Once at work, in the event that the installer observes the existence of elements that

can cause shadows on the solar collectors and have not be taken into account in the

design of the system, as protection walls in terraces, fireplaces, outdoor air

conditioning units or other elements, should inform the designer of the project or the

owner of the property in order to revise or amend the calculations made for the

location of the collectors, if necessary.

The system of fixing the support frame of the solar collectors to the building also

must be determined in the design phase of the installation, for example by

conducting benches built on a flat roof. In this case, the thickness and size of the

bench should be sufficient to ensure stability of the whole in case of strong gusts of

wind. In any case, the solution adopted should ensure the solidity and stability of the

setting without compromising the watertight integrity of the deck. To facilitate the

design of the fixing system, figures 7 to 13 show the distances between the support

frames of the solar collectors.

4. Banks of Collectors

The solar collectors can be connected with each other to form banks of up to 6 units

in parallel, connecting the top and bottom of the collectors through the fittings

included in the set.

The dimensions of pipe connections for collector arrays up to 20m² is 22mm.

It is recommended that the connections between the different banks of collectors are

also conducted in parallel. However, the connection of up to two banks of solar

collectors in series is allowed.

In the following figures from 6 to 13 shows the dimensions of the solar collectors from

1 to 6 units and for different angles of inclination. Additionally, there should be

sufficient space around the banks of collectors to perform with comfort the hydraulic

connections.
