DIY instructional video to place solar panels on a flat roof.
Connecting your solar panels is actually a piece of cake.
Connecting your solar panels is actually a piece of cake.

Step 1 of 53
2
Step 2 of 53
Make sure that the roof surface on which the panels must be mounted is clean, dry and flat.
3
Step 3 of 53
Measure the height of the roof edge. Double this distance to determine the front of the first row.
4
Step 4 of 53

To determine the side of the panel row, you will use the same rule.

For aesthetic reasons, you can choose to work further from the roof edge.

5
Step 5 of 53
The starting angle of our first row panels is now fixed.
6
Step 6 of 53

Use the same distance at the end of the row. This ensures the row aligns properly with the façade.

7
Step 7 of 53

Hold the chalk line tightly along both markings. Pull it taut and snap the line to make the mark.

8
Step 8 of 53

To mark a right angle, use the supplied square.

9
Step 9 of 53

Use the square and a chalk line to make a vertical mark perpendicular to the horizontal marking.

10
Step 10 of 53

Place a meter against the vertical marking. Now place a marking every 170 cm.

This is the same as the width of one panel. Now it's time to place the base units.

11
Step 11 of 53

Make sure that you don't damage the roof with the end. On the front of each first panel, we attach protective end rubbers.


Remove the protective film on the self-adhesive side of the rubbers.

12
Step 12 of 53

Stick the end rubber to the correct spot on the rail using the self-adhesive side.

13
Step 13 of 53
Push the plugs into the provided holes and press them firmly.
14
Step 14 of 53

Carefully place the base units, equipped with protective end rubbers, onto the marked positions.

15
Step 15 of 53
The following row base units are easily attached to the end of the row that you have already placed.
16
Step 16 of 53

Slide the front into the rear rail of the unit in front.

17
Step 17 of 53

Make sure that all units are neatly attached to each other in the holes provided for this with the included self-tapping screws.

18
Step 18 of 53

Adjust the supplied spacer correctly.

Do this by placing it along the long side of a solar panel. Position the ends against the panel edges and tighten the screw.

19
Step 19 of 53
Use the distance holder to simply determine and hold the distance between the base units.
20
Step 20 of 53

After determining the correct distance between two base units, place two L-profiles between them, where a ballast tile will later be positioned.

21
Step 21 of 53

Also for this, self-tappings screws are provided. 

22
Step 22 of 53
Between the two L-profiles, place a central support to strengthen the whole.
23
Step 23 of 53
Attach the central support to the L-profiles.
24
Step 24 of 53
Between all base units, L-profiles with a central support are placed.
25
Step 25 of 53
The first ballast tiles can now be placed on the L-profiles.
26
Step 26 of 53

Double-check that all base units still align properly with the marked positions.

27
Step 27 of 53

If everything connects nicely, also place the rest of the L-profiles and ballast tiles. Follow the provided ballast plan.

Try to place the tiles as close to the base units as possible.

28
Step 28 of 53

Provide the necessary cables to connect your panels to the inverter.

29
Step 29 of 53

The cables can be attached to the base units with zip ties.

Follow the provided string plan. 

30
Step 30 of 53

We ensure that our setup is grounded.

One cable is provided for grounding in the string plan. Strip the end of this cable and attach a cable lug.

31
Step 31 of 53

Mark the grounding cable with heat shrink tubing or tape.

32
Step 32 of 53

Secure the grounding cable to the base unit using a self-tapping screw.

33
Step 33 of 53

Attach a connector to the string cables.

Use the connector crimping tool for this.

34
Step 34 of 53

Push firmly until you hear a click, then hand-tighten the connector securely.

35
Step 35 of 53

Apply ceramic grease to the spots where our panels will be mounted.

36
Step 36 of 53

Watch out for damage. Never place a panel with its corner on the roof surface.

37
Step 37 of 53

Remove the zip ties to release the connectors.

38
Step 38 of 53
Place the base unit on the base unit. Make sure the bottom side is at the right angle.
39
Step 39 of 53

Secure the base unit to the base unit with clamps. 

On the outside, you use end clamps.

Do not fully tighten the screws.

40
Step 40 of 53

Between two rows you use middle clamps.

41
Step 41 of 53

Place the next panels in the same way.

42
Step 42 of 53

Once a full row is in place, you can fully tighten the end clamps.

43
Step 43 of 53

Connect the panel with the cable closest to the inverter to this cable.

44
Step 44 of 53
Connect the other panels in the same way. The connectors are well connected when you hear a click.
45
Step 45 of 53

Secure the cables with a zip tie to the L-profile. 

This way, the cables won’t end up lying in water.

46
Step 46 of 53

At the back of each base unit, we install a backplate.

47
Step 47 of 53

Place a back plate on the back of each base unit.


48
Step 48 of 53

Let this plate rest in the designated groove and secure it with the self-tapping screws.

49
Step 49 of 53

Congratulations, the task is done.

Now we can go inside.

50
Step 50 of 53

We will attach the converter to the wall using a mounting plate. 

51
Step 51 of 53

You can test already how the converter will be attached to the mounting plate.


52
Step 52 of 53

Using a spirit level, attach the mounting plate to the wall.


The direction of the arrow clearly indicates how the mounting plate should be placed.


Make sure there is enough free space around the converter.  


53
Step 53 of 53

The inverter can now be easily mounted to the wall.

The job is done!
