Introduction This manual contains essential information about electrical and mechanical installation that must be followed before handling, installing, and maintaining Roofit.Solar PV modules. Failure to follow these safety instructions may result in personal injury or property damage.

Page 5: Safety
The distributor of our Products is required to provide this manual to the PV system owners. Roofit.Solar is designed to meet the requirements of the IEC 61215 and IEC 61730 standards. Perform structural analysis of the roof before installing Roofit.Solar Products.
Page 6: Main Precautions
Main Precautions Always follow the safety precautions listed below when dealing with Roofit.Solar Product: • Keep the PV module packages indoors until they are ready to be installed. Transport and store the PV modules in appropriate packaging in a ventilated, rainproof, and dry location.
Page 7: Fire Safety
In case of fire, stay away from all elements of the PV system, until the area is safe. Roofit.Solar recommends using a combiner box for buildings with PV systems to protect the house and inverter(s) from unexpected overvoltage. The combiner box is equipped with an emergency disconnect mechanism that shuts down the PV system and protects it from overvoltage caused by lightning strikes.
Page 8: Roofit.solar Product Information
Roofit.Solar Product Information The Roofit.Solar product is a building-integrated photovoltaic (BIPV) system that can be used as a construction material on roofs or building facades. General information about the components of Roofit.Solar PV module is depicted in the pictures below. Detailed information about their electrical, mechanical and thermal characteristics can be found in datasheets of the products.
Page 9: Pv System Planning
1600 Pa with a safety factor of 1.5. Roofit.Solar is not responsible for any damage caused by lightning, so it is recommended to install surge protection in areas with a high probability of lightning strikes. The product should not be installed in locations where corrosive agents or flammable gases may be present.
Page 10 The recommended center-to-center batten spacing is 200mm to ensure proper wind resistance. A ventilation gap of at least 50mm should be maintained between the Roofit.Solar Product and the moisture barrier, which can be achieved by using a ventilation board and batten of appropriate thicknesses. Additionally, a minimum of 200mm from the bottom of the roof should be fully decked.
Page 11: Measuring The Roof
Measuring the roof The customer needs to provide Roofit.Solar with a drawing or a simple sketch of their roof with important measurements for the PV system. Length of the roof is measured from the outer surface of the farthest facing board from the eaves to the middle of the ridge.
Page 12 Roofit.Solar products can either cover the entire roof or be used with regular metal roofing materials, depending on the design of the roof. However, all elements that penetrate the roof (like chimneys or skylights) and the valleys need to be surrounded with standard metal sheets that are 300mm wide.

Extension cable (> 1 m) DC cables are used to connect Roofit.solar DC Strings with the inverter. Customized length. Extension cables are needed if the connection distance between the modules is more than 1 m. Grounding cable...

Failure to do so can result in damage to the Product and injury to individuals. Make sure all electrical connections are secure and tight – confirm that you hear “click” to indicate that the connection is successful.
Page 15 The inverter cables (String [–], String [+]), the grounding and extension cables connecting the Roofit.Solar Products should be positioned on site (i.e. between battens) before the installation. Loose cables should be fixed to the wooden structure with the help of cable holder clips.
Page 16: Wiring Considerations
NB. Roofit.Solar PV systems must be equipped with DC arc fault circuit protection to provide protection against fires that may arise from the arcing faults in PV system components or wiring. Therefore, inverters with arc fault circuit interrupter (AFCI) must be used for the Roofit.Solar PV system installation.
Page 17: Grounding
If the building has more than one type of active surface on the roof (i.e., Roofit.Solar Products covering different sides of the roof), they can be connected in one grounding circuit to minimize the number of grounding cables as shown in the picture.

Some of the steps in Case 1 are universal and won’t be repeated in the other cases. Therefore, in any case, go through Case 1 and consult with our Technical Support for any questions. Case 1: Roof fully covered with Roofit.Solar modules. Click Safety and Installation Manual...
Page 20 When installing the first sheet, make sure the bottom backbend is tucked under the lip of the eaves flashing. Then, pull the sheet towards the ridge until the lip of the eaves flashing is at the bottom of the sheet’s backbend. Click Safety and Installation Manual...
Page 21 A minimum of 200mm from the bottom edge of the roof should have full decking, and additional screws have to be used to ensure the proper fixation of the metal. For narrow (475mm) metal sheet installation, refer to the Ruukki manual. Click Safety and Installation Manual...
Page 22 All PV modules come with a precut lock in the upper left and right corner. All PV modules, except those finishing the ridge of the roof, need to have an additional cut made in the right corner. Click Safety and Installation Manual...
Page 23 Before fixing the PV module, make sure to connect the cable with the previous module. Remove the dust caps and push the connectors together until you hear a *click*. Bring the second cable of the PV-module out from the left side to ease the connection of the next module afterwards.
Page 24 Step 11 When installing the next module on top, make sure to align it with the seam cuts of the lower module, leaving a 5mm gap between the two glass surfaces. Click Safety and Installation Manual...
Page 25 During the installation, be aware that multiple metal layers come together in the overlap area, which can cause misalignment. Make sure to check the width of the roof and if needed, adjust the line by slightly pulling the left side lock before attaching the screw to ensure everything is lined up correctly.

Page 30 To install a regular metal sheet on top of the PV module, a 200mm overlap element is placed on the lower PV module. Overlap element is attached with 3 flat-head screws. If there is no batten underneath, install one. Bending the lower side of the overlap element upwards will make the next steps easier. Click Safety and Installation Manual...
Page 31 Step 4. Lock both roofing sheet seams by tapping along the inner edges of the seam with a rubber mallet and a wooden block. Pay attention not to hit the glass of the lower PV module. Click Safety and Installation Manual...
Page 32: Maintenance
Negative environmental effects, such as foreign objects casting shadows or laying directly on the roof, may adversely affect the power output of the Product. Roofit.Solar advises that the PV part of the system should not be obstructed at any time. The Product cleaning frequency depends on the environmental factors.
