We congratulate you on your purchase of the SOLARWATT

EasyIn In-Roof PV System with its extremely reliable dou-

ble-glazed con guration.

The quality of the modules made exclusively in Germany

is ensured by repeated product testing throughout the

entire production process.

SOLARWATT modules are tested by certi ed institutions

and meet the requirements of the extended testing stan-

dard IEC 61215 Ed. 2 and safety standard IEC 61730. SO-

LARWATT's own research and development department

has a wealth of measuring, testing and environmental

simulation equipment for testing its products to far ex-

ceed the requirements of the usual standards and ensure

continuous optimization.

The SOLARWATT EasyIn System is an intelligent solution

which is easy to install thanks to the innovative and prov-

en module design based on the roof tile principle. SOLAR-

WATT EasyIn Modules are mounted onto the roof battens

and simply connected to each other. The frame pro les

are used to attach the modules to the roof battens and

to secure the rainproof connection to adjacent modules.

This is how the SOLARWATT EasyIn System replaces tra-

ditional roo ng, upgrades your roof with the additional

bene t of energy generation and has an in-roof look that

sets standards.

1 General information

1.1 About these instructions

These instructions explain how to install SOLARWATT

EasyIn modules with double-glazed laminate on the roof.

They are intended for authorized personnel familiar with

installation on the basis of their occupational quali ca-

tions. Modules should be installed and connected only

by trained, authorized personnel. These personnel must

be familiarized with these installation instructions before

they undertake the installation and they must comply

with them so that the system is fully functionally secure

and rainproof.

The instructions explain the installation in individual se-

quential work steps. We recommend that you observe

the sequential order described, even if a deviating job

sequence should arise.

Please note that in some work steps the installation of the

SOLARWATT roo ng frame is referred to. If you have also

purchased one of these, please use the relevant installa-

tion instructions for its installation.

If you have not purchased the SOLARWATT roo ng frame,

we advise that you require a customized enclosure frame

to connect to the rest of the roof. This type of custom-

ized solution is appropriate when the roof has speci c

features such as dormer windows or windows in the area

of the solar system, but it must still observe roo ng trade

guidelines and rules.

1.2 Validity

These installation instructions apply to the SOLARWATT

EasyIn 60M style module with double-glazed con gura-

tion (covering length 1.642 mm), in connection with the

Prior to the  rst installation we recommend a training

course given by our sta .

2 Transport, Storage, Handling

IMPORTANT

SOLARWATT modules are manufactured using high-quality materials, making them extremely sturdy and

long-lasting. The modules should nevertheless be left in the packaging until installation to help prevent any

damage.

Transport

IMPORTANT

You are obligated to check all goods delivered as well as their packaging immediately for transport damage.

What to do in event of transport damage

If any damage is noted, note it on the shipping papers describing each pallet in detail and take photographs as docu-

mentary evidence. Have the driver countersign these notes. If more than 10 solar modules on one pallet are damaged,

refuse to accept the pallet. Please ll out the "Transport Damage Complaint Notication" form (www.solarwatt.de) and

return it to SOLARWATT GmbH.

Please do not remove any parts or rating plates from the modules. Do not install modules if damaged.

Disposal of packaging

Please recycle the packaging (foils, straps, packing corners and the pallet). Contact the local waste management com-

pany responsible regarding recycling.

IMPORTANT

Stacking pallets will cause damage to the SOLARWATT EasyIn Modules and must absolutely be avoided! It is

recommended that the SOLARWATT EasyIn modules are stored in a dry and frost-free place in their original pack-

aging until they are installed. Please also observe the warning notices stated on the packaging units.

Handling on the roof and the ground

SOLARWATT EasyIn modules are delivered on a pallet and are well protected by water-proof foil against the eects of

weather. The modules can be removed easily by simply lifting the two module ends. The modules must not be tilted,

because they are hooked into one another and tilting could bend the module frame.

The innovative design of the modules makes them easy to handle on the roof. The lug on the top part of the frame

enables a safe interim storage on the roof battens at any time.

4 Notes on installation and connection

The installation of the EasyIn modules has been well

prepared at the factory due to their dierent features. In-

correct installation or commissioning can lead to damage

which could consequently pose a risk to people.

Produce a plan for potential maintenance and repair

work. This should include documentation relating to the

layout of the modules including assigned serial numbers

and cable routing. Keep this together with the documen-

tation relating to your photovoltaic system.

The structural analysis for the roof construction, specied

in these installation instructions in conjunction with the

EasyIn system, is provided according to DIN 1052 and

DIN 1055.

IMPORTANT

Whichever EasyIn system is to be installed, the following structural requirements must be observed:

1. In the installation of load-bearing wood fastenings, the connector spacings speci ed in the standard must

be complied with.

2. Batten joints are to be designed according to ZVDH guidelines.

NOTE

Always install the modules on suitable roof battens. Ensure that mechanical tension in the actual structure (e.g.

roof framework) is not transferred to the module. Check the static suitability of the building for the installation

of a solar power system.

NOTE

The electric wiring must already be in place before each module is attached because after the modules have

been attached the connections will no longer be accessible.

NOTE

The electric wiring of the EasyIn system components is

contingent on local conditions and is therefore to be laid

out and installed on a case-by-case basis by each install-

er. A few helpful notes will be provided in this regard.

During the design process of the EasyIn system relevant

structural precautions were taken regarding the imper-

meability of the roof.

As no warranty can be assumed for the correct technical

installation, it is essential that the EasyIn system and the

corresponding module connection/enclosure frame are

installed by a technical expert who can also guarantee

the impermeability of the roof.

IMPORTANT

The drainage holes in the module frame must not be covered, as it could cause frost damage on the module

frame. Modules must be installed so that no water can run towards the cable screws. The module connector must

not lie on the sarking membrane. Therefore you must install the module in the way shown and fasten the cable/

connector as usual to the roof battens.

NOTE

It is recommended to prepare a string plan of the PV system and measure the respective string voltages after

the modules wired in a row are installed by appropriately trained technicians. This should also be documented

in writing.

NOTE

General conditions to be observed

●The system has only been tested with the materials

stated in System Components (see Chapter 8) and is

therefore only approved for these.

●To ensure sucient ventilation counter battens must

be used.

●The sarking membrane supplied must be used as

mandatory.

●Max. rafter spacing: 1 m; max. building height: 18 m;

max. wind load zone: 2; max. snow load zone: 3 and

max. 530 meters above sea level (or equivalent): H

and I (according to DIN 1055).

5 Preparation and planning

Use the planning tool provided on www.solarwatt.de to

create a layout plan for the entire roof. This must include

eaves, the module eld, ridge and tile cover, along with

any other features of the building such as skylights or

dormers.

5.1 Eaves

The conguration in the eaves area is an important

pre-condition for the installation of the module eld (e.g.

accessibility). Therefore you must plan and implement

this carefully and in accordance with the technical rules

of the German Roong Trade (ZVDH) and the roof struc-

ture chosen. As specied in the EasyIn planning sheet the

minimum spacing between module eld and eave must

be complied with for the following reasons:

●Increased wind load at the roof edges

●Construction of a functioning water drain to avoid

water pockets forming, backll and overspilling rain-

water.

5.2 Ridge

The ridge area must include sucient space so as to

comply with the minimum spacing between the topmost

module edge and/or roong frame and ridge as stated in

the EasyIn planning sheet.

5.3 Batten layout, vertically from bottom to top.

For clarity purposes the substructure below is rst dis-

played in the vertical, and then in the horizontal instal-

lation orientation (see chapter Figure 2 on page 9).

In Figure 3 on page 10 the vertical system congura-

tion for 2 module rows is displayed (there is an enlarged

image of Figure 3 in Chapter 9.1 on page 33).

The top part shows the requisite layout of the battens for

the layout and the fastening of the modules and the roof-

ing frame.

The bottom part shows the layout of the battens for the

roof tiles which are laid with a standardized batten spac-

ing (LA) next to the module eld.

The two areas are connected via the continuous battens U

below, and O above, the module eld and which also run

in the roof tile area.

Figure 2

IMPORTANT

The speci ed spacings and tolerances for the layout of the battens under the modules must be complied with

for static reasons. For batten distances under the roo ng frame, please observe the information provided by the

relevant supplier.

NOTE

Please note for planning purposes, that the spacing between battens U and O for the module area and roof tile

area must align with each other.

You must also design the eave and ridge and adapt it together with the batten spacing LA to the circumstances

of your roof.

Measurement A is determined by the roof-pitch depen-

dent overlap length between the enclosure frame lower

edge (dead plate end on eaves) and the roof tiles as well

as the overhang length of the respective roof tile (see Fig-

ure 13 on page 18). When installing the SOLARWATT

enclosure frame, the lower enclosure frame including the

dead plate has a vertical length of 250 ± 10 mm, related

to the top side of the supporting board 98 x 20 mm.

In Table 2 on page 13 Measurement A is generally set

at 150 mm.

Roof battens 7 are needed directly above the module

eld to support and attach the upper enclosure frame.

When using the SOLARWATT roong frame the measure-

ments for battens 7.1 to 7.3 are stated in the relevant in-

stallation instructions.

IMPORTANT

Measurement B does not describe the position of

batten 7.2.

Note that the spacings for battens 7.1 to 7.3 for a roof

pitch 30-65° and 22-29° are dierent.

This results in the following values for Measurement B:

B = 180 mm for roong frame 30-65°

B = 310 mm for roong frame 22-29°

5.3.3 Battens 1-6 under each module

Table 1 Shows another overview of the batten spacings

and tolerances for the batten layout underneath the solar

module.

The reference point for the batten spacings of the low-

est module row is the top side of the supporting board

98x20.

The same batten spacings also apply to every higher row

of modules. The reference point then used is the top side

of aluminum guide rail 6 of the module row beneath.

For battens 4 (14; 24; 34) a larger tolerance range applies

because these are only used as protection against any fall

through. For this purpose in most cases the nearest bat-

tens from the roof tile area can simply be planned to be

pulled through.

For batten measurements for complete module elds, see Chapter 9.4 on page 36.

5.3.4 Battens for roof tile area

The total spacing between the battens U and O is deter-

mined primarily by the module measurements. There are

limited change options which are restricted by the roof

pitch and primarily by the shape and measurements of

the planned roof tile:

●Spacing A is also dependent on the structural height

of the roof tile above the batten (limit value approx.

50 mm) and the possibility of grinding higher water

seams at the top end of the roof tile.

●Possibility of shortening the roof tile (measurement

K) in the roof tile row above the module eld.

●Possibility for additional overlap of the top enclosure

frame by the roof tile (measurement Ü), whereby it

must be ensured that the inherent load of the roof

tile must only project over the specied supports in

the enclosure frame on the roof.

●The size of overlap Ü and of shortening K depends on

the roof tile and the top roof tiling sheet and must be

determined by a roofer.

If these possibilities are not sucient, the use of shorter

or longer roof tiles should be considered, in other words,

one tile row more or less next to the module eld.

Batten spacing LA for the tile area is determined from the

total spacing between battens U and O which shall also

then apply to any further tile rows above and below the

module eld.

5.3.5 Optimum number of roof tile rows

Table 2 on page 13 includes for each number of mod-

ule rows the respective optimum number of tile rows.

With this number of tile rows there are no dimensional

overlaps of battens from the module area with battens

from the tile area. This enables both batten types at the

left and right edges of the module eld to be pulled

through to the next counter batten/rafter and fastened

there. An overlap is only possible with battens for the top

enclosure frame.

5.3.6 Batten joints between rafters

There may be reasons to select a non-optimal number of

tile rows so that some battens from the tile area can over-

lap, in full or in part, with battens from the module area.

In this case the roof statics must be ensured by additional

vertical and horizontal battens. Chapter 9.2 on page 33

in the appendix lists a design variant for a transition be-

tween roof batten and aluminum guide rail for a rafter

spacing of 1.0 m. Transitions between wood battens are

to be implemented in the same way.

5.3.7 Examples of batten layouts for a roof pitch of 30-65°

Table 2 species total spacing D between battens U and

O as well as batten spacing LA for dierent roof tile types

for a structure as in Figure 3 on page 10. Also specied

are vertical overlap lengths

●between the lower dead plate of the SOLARWATT

roong frame and roof tiles on batten U

●between the roof tiles in the tile area next to the

module eld.

For information on other roof tile types, see Chapter 9.3

on page 35.

Measurements and spacings for eaves and ridge are not

included in this, but must be designed separately based

on the circumstances of the roof.

Figure 4 shows the horizontal layout of the modules and

the side groove of the SOLARWATT roong frame using

as an example a module eld with 3 adjacently placed

modules.

Measurement H is derived from the module-covering

width 1.015 mm including the installation spacing of 2

mm between the modules.

This installation spacing should be created using two

spacers which are already stuck onto the left side of each

module.

Module eld standing seam F is the spacing between the

standing seams of the roong frame side groove and at

the same time the outermost limit for the roof tiles.

6 Step-by-step installation

6.1 Sarking membrane

The sarking membrane supplied with the delivery is laid

parallel to the eaves. Fasten the sheets free of crimps and

wrinkles. The minimum overlap both for the height and

side overlaps is 100 mm.

Stick the height overlaps using the adhesive strip on the

sheet edges (back and front) and the side overlaps un-

der the counter batten. The printed side of the sarking

membrane is the top side and must show upwards in the

laying.

Fix the sarking membrane covered in the area of the

height and side overlaps or under the counter batten (on

the roof rafters) with staples or  at-headed nails. The  nal

fastening is done by applying the counter batten. Stricter

requirements for fastening counter battens apply in the

module  eld area. These are described in Chapter 6.2.3

on page 17 and are implemented after the roof battens

have been attached.

Figure 9

min. 100 mm

NOTE

Impermeability of the sarking membrane

When using the supplied sarking membrane and penetrating fastening (nails, screws) no nail sealing strip is

required.

NOTE

6.2 Roof battening

The battening is installed in the orientation of eave to ridge.

6.2.1 Special case batten joints

If batten joints are required in the module area, please

ensure that the spacing between the joint surface and

screw point is wide enough. To ensure static stability, a

lateral doubling on the batten joint or the solution as il-

lustrated in the diagram with a  at-head screw 6 x 80 is

required.

Figure 10

6.2.2 Fastening battens

In the module area the horizontally running battens are

to be screwed tightly into the counter batten with a  at-

head screw 6 x 80.

6.2.3 Extra fastening of battens

On all battens into which mounting brackets for modules

are screwed, in order to secure static stability, all count-

er battens must also be screwed immediately above and

below the roof battens with  at-head screws 6 x 80 (spac-

ing of screws to cross batten at least 20 mm). This a ects

battens 2, 3, 4 and 5 (12; 13; 14; 15) (22; 23; 24; 25) (32;

33; 34; 35) etc.

Figure 11

Additional  at-head screw 6 x 80

6.2.4 Start of installation with batten U and bat-

ten 1

First install batten U according to your layout plan. As

spacing A refers to the top edge of supporting board

98x20, batten 1 itself must be attached at a spacing of “A

MINUS 20 mm” to batten U (see Figure 13 on page 18).

Figure 12

6.2.5 Fastening support board 98x20

The support board is used for the eave-side module con-

struction of the lowest module row. Position the board

closely to the top side of batten 1 and  x it with the sup-

plied mounting brackets (see chapter 8.1 Delivery scope

on page 30). The mounting brackets are to be fastened

on each counter batten of the module  eld with 2 wood

screws 6 x 60. To avoid a split of the supporting board and

a con ict with the batten screwing, the mounting brackets

must not be screwed to the supporting board. U

6.2.6 Laying battens 2; 3; 4; 5

These battens are to be arranged and fastened according

to the measurement and tolerance information in Figure

3 on page 10 (or also in Table 1 on page 11).

6.2.7 Laying batten 6: Aluminum guide rail

40x40 on the fastening plate

The  rst aluminum guide rail must be laid with a spacing

of 1.642 mm to the top edge of the supporting board 98

x 20. Here it is essential that the tolerance requirement

+/- 5 mm be observed because the aluminum guide rail is

also used as a measurement reference point for the mod-

ule row laid out above (see Figure 3).

The aluminum guide rails are  xed with fastening plates

which are fastened centrally to the counter battens with

wood screws 6 x 60.

NOTE

You must  rst push the required number of fastening plates onto the aluminum guide rail before you start fas-

tening the counter batten!

NOTE

Transitions from one aluminum guide rail to the others

are made in the counter batten area.

The counter battens under the fastening plates are also

to be xed with 4 at-head screws 6 x 80 (see Figure 16).

6.2.8 Laying battens for further module rows

For the battening of module row 2, the top of the already

laid aluminum guide rail 6 of module row 1 is used as a

reference surface.

Battens 12, 13, 14, 15 and aluminum guide rail 16 are

to be arranged in the same way and must be fastened as

described in Chapters 6.2.6 to 6.2.7.

Complete the module eld in the same way for all other

module rows up to the aluminum guide rail on the top

module eld end.

6.2.9 Laying battens for further the top enclo-

sure frame and batten O

Lay the battens for the top enclosure frame according to

the information provided by the supplier of your enclo-

sure frame. When using the SOLARWATT roong frame

the measurements for the roong frame are stated in the

installation instructions.

Batten O is positioned with a total distance D to batten U

(see Chapter 5.3).

6.3 Module installation

It is recommended to install modules from the bottom

right to top left (see Figure 32 on page 25). The system

can also be installed by starting in the middle or outside

left in the lowest row.

IMPORTANT

The SOLARWATT EasyIn System design is based on

the roof tile system. Therefore the overlaps between

the modules and the connections to the enclosure

frame and to the roof tiles must be implemented

very carefully.

NOTE

Before you can install any modules in the lowest

module row, the relevant lower enclosure frame

must already be laid there. Please always follow the

relevant installation instructions for the enclosure

frame.

NOTE

Mount the  rst module on the lowest aluminum guide rail

on the bottom right edge of the module  eld (see Figure

17). Move the module into the desired position. The mod-

ule lug should lie  at on the aluminum guide rail over the

total length (see Figure 18).

NOTE

For the subsequent electrical wiring prepare the

connecting cable above the module or next to the

roof batten.
