Contact with electrically active parts of the module such as terminals can result in burns, sparks, and lethal shock whether the module is connected or disconnected. Modules produce electricity when sunlight or other sources illuminate the front face. The voltage from a single module is not considered a shock hazard. When modules are connected in series, voltages are additive. When modules are connected in parallel, current is additive. Consequently, a multi-module system can produce high voltages and current, which constitute an increased hazard and could cause serious injury or death. Aesthetic Green Power, Inc.

AESTHETIC GREEN POWER RESERVES THE RIGHT TO MAKE CHANGES TO THE PRODUCT, SPECIFICATIONS, OR GUIDE WITHOUT PRIOR NOTICE. GENERAL INFORMATION THE INSTALLATION OF MODULES REQUIRES A GREAT DEGREE OF SKILL AND SHOULD ONLY BE PERFORMED BY QUALIFIED LICENSED PROFESSIONALS, INCLUDING, WITHOUT LIMITATION, LICENSED CONTRACTORS AND LICENSED ELECTRICIANS. THE INSTALLER ASSUMES THE RISK OF ALL INJURY THAT MIGHT OCCUR DURING INSTALLATION, INCLUDING, WITHOUT LIMITATION, THE RISK OF ELECTRIC SHOCK. GENERAL SAFETY The word "module" as used in this manual refers to one or more solar electric modules. Before installing a module, contact appropriate authorities to determine permit, installation, and inspection requirements that should be followed. This should be done not only for installations in conjunction with buildings, but also for marine and motor vehicle applications for which additional requirements may apply. Module installation and operation should be performed by qualified personnel only. If not otherwise specified, it is recommended that the latest local, national, and international electrical code requirements be followed. Electrically ground metal parts for all systems of any voltage. Avoid electrical hazards when installing, wiring, operating and maintaining the module. A module generates DC electricity when exposed to sunlight or other light sources. Do not touch terminals while module is exposed to light or during installation. Provide suitable guards to prevent contact with 30VDC or greater. As an added precaution, use properly insulated tools only. When installing or working with module or wiring, cover module face completely with opaque material to halt production of electricity. Because sparks may be produced, do not install module where flammable gases or vapors are present. Do not use modules of different configurations in the same system. Do not artificially concentrate sunlight on the module. It is recommended that the module remains packed in the box until time of installation. Work only under dry conditions, with a dry module and tools. Special construction may be required to help provide proper installation. When installing modules on any structure above ground, avoid any possible falling safety hazards by following appropriate safety practice(s) and using required safety equipment. Both roof construction and module installation design have an effect on the fire resistance of the building. Improper installation may contribute to hazards in the event of fire. Additional devices such as ground fault, fuses, and disconnects may be required. Keep back surface free from foreign objects. Avoid sharp edges. Do not stand or step on module. When handling glass always wear safety glasses. All modules should be handled with care using proper safety equipment. Due to the weight of the module one should never try to move a module without safety precautions and glass lifting equipment. Any glass lifting/handling equipment can be used that is designed for the proper module weight and size. Do not drop module or allow objects to fall on module. Never leave a module unsupported or unsecured. If a module should fall, the glass can break. A module with broken glass cannot be repaired and must not be used. Follow all safety precautions of other used components. It must be assured that other system components do not generate any hazard of any mechanical or electrical nature to the module. Children should not be allowed near the solar electric installation. Use module for its intended function only. Follow all module manufacturers instructions. Do not disassemble the module, or remove any part or label installed by the manufacturer. Do not treat the back of the module with paint or adhesives.

PEX tools a. PEX cutter b. PEX crimper c. PEX crimp Gauge 8. Pipe bender Underlayment Roof Preparation Before installation of the TallSlate TM modules, the roof needs to be properly prepared according to all local building codes. Ensure that damaged/rotting plywood is repaired and that roofing felt (min. 30 lb.) and/or ice and water shield is installed for waterproofing. Flashing Install drip edge at eave beneath the underlayment. At the rake, install flashing on top of the underlayment. Ensure that flashing material is non-reactive with galvanized steel. If you are unsure, please refer to the chart below (Figure 10). Figure 10 Metal Compatibility for Electrolysis Aesthetic Green Power, Inc. Page 8 of 21 Rev. 0 11/23/16

9 Specialized flashing will be required at the rake (Figures 11-13). This flashing can be folded from 16 oz. copper or other suitable flashing material. Figure 11 Roof Profile Figure 12 Roof Cross Section at A Aesthetic Green Power, Inc. Page 9 of 21 Rev. 0 11/23/16

10 Figure 13 Rake Flashing Detail Note: This flashing size may vary depending on counter batten height. See Resources section at the end of this manual for detail.. Aesthetic Green Power, Inc. Page 10 of 21 Rev. 0 11/23/16

11 Installation Instructions Wood Battens Before laying the Nu-lok TM Primary Battens, vertical and horizontal wood battens must be installed. The vertical counter battens prevent moisture from collecting between the horizontal battens and allows wiring to be routed underneath. Use 2x2 lumber for the vertical counter battens. Alternatively, 2x4 lumber ripped in half may be used (Figure 14). In either case, the height of the counter battens will be 1-1/2. Counter battens should be fastened directly into the rafters using " x 2-1/2" galvanized steel nails or #10 2-1/2 galvanized steel wood screws. Figure 14 Vertical Counter Batten Size Use 1-1/2 W x 1 H horizontal wood battens. These can be fabricated by ripping 2x4 lumber into 1 widths (Figure 15). Figure 15 - Horizontal Batten Size Aesthetic Green Power, Inc. Page 11 of 21 Rev. 0 11/23/16

12 Horizontal wood battens should be fastened into the counter battens using x 2 galvanized steel nails or #10 2 galvanized steel wood screws. Fasten the battens at a distance of 12-1/8 (308mm) center-to-center (Figure 16). Figure 16 Wood Battens Layout The distance of the bottom edge of the counter batten to the edge of roof deck, d, will vary depending on roof pitch and eave fascia placement. To determine the distance d, vertically align the top edge of the first horizontal batten to the outer edge of eave fascia (Figure 17). This will allow for proper placement of the eave closure, and ensures that it will be flush with the eave fascia (Figures 18 and 19). Figure 17 Wood Batten Alignment Aesthetic Green Power, Inc.

13 Figure 18 Eave Closure Figure 19 Eave Closure Detail Aesthetic Green Power, Inc. Page 13 of 21 Rev. 0 11/23/16

14 The distance l 1 (Figure 19) is dependent on the pitch of the roof and can be estimated using the chart below (Figure 20). Roof Pitch l 1 4:12, 5:12, 6:12 1 / 25 mm 7:12, 8:12, 9:12 1-1/8 / 28mm 10:12, 11:12, 12:12 1-1/4 / 32mm Figure 20 l 1 of Eave Closure The distance l 2 (Figure 19) is dependent on a number of factors, including the pitch of the roof and fascia placement. As such, this distance should be determined in the field. After the wood battens are in place, per Figure 18, determine the distance l 2, making sure there is sufficient clearance at the bottom to allow moisture to escape off the drip edge. Attach the eave closure to the first horizontal wood batten. The eave closure can be folded from 16 oz. copper or other suitable flashing material. Refer to the chart in Figure 10 for more information on selecting a flashing material. BITERS Battens The BITERS battens are installed between the horizontal wood battens. Align the bottom edge of the BITERS batten with the horizontal wood batten below it, leaving a 1.5 gap above the BITERS batten. The gap will leave room for the wires to be routed underneath the BITERS battens. Attach the BITERS battens to the vertical counter battens using #10 1-1/2 galvanized steel or weather-resistant coated steel self-piercing screws. See Figure 21 for detail. Install the PEX tubing using the pipe bender, cutter, crimper, and PEX couplings. For PEX tube layout, please consult with a solar thermal installer for an appropriate thermal system design. Four BITERS clips should be installed per batten to secure the PEX tubing inside (see Figure 21). Attach the clips using #10 ½ galvanized steel or weather-resistant coated steel self-piercing or selfdrilling screws. Aesthetic Green Power, Inc. Page 14 of 21 Rev. 0 11/23/16

15 Nu-lok TM Primary Battens Figure 21 - BITERS Battens and Eave Closure Nu-lok TM Primary Battens are fastened into the horizontal wood battens using a pneumatic nail gun. Ensure that any fastener is non-reactive with the Nu-lok TM galvanized steel primary battens (see Figure 10 for detail). Figure 22 Nu-lok TM Primary Battens Aesthetic Green Power, Inc. Page 15 of 21 Rev. 0 11/23/16

16 Nu-lok TM Link Channels and Clips Install Nu-lok TM Clips into the Nu-lok TM Link Channels before bringing link channel/clip assemblies onto the roof (Figure 23). Figure 23 - Nu-lok TM Link Channel and Clip One link channel is used to support the center of each TallSlate TM, while an additional two link channels are used to support the ends of the module. Adjacent modules will share one link channel at the boundary between the two modules. Install the first link channel all the way at the end of the primary battens (Figure 24). The second link channel should be installed at 47-3/8 (1203mm) from the edge of the TallSlate TM to the center of the link channel. Make sure the TallSlate TM overhangs the rake fascia by at least ½. The third link channel should be placed halfway between the first and second link channels. The position of the second link channel may need to be adjusted once the TallSlate TM is in place. The right edge of the TallSlate TM should fall approximately 1/8 (3mm) left of the center of the second link channel. Figure 24 Link Channels for First TallSlate TM The remaining link channels in each row of TallSlate TM modules should be spaced at 23-3/4 (603mm) (Figure 24). It is up to the installer to decide whether to install modules across rows or in columns up the roof slope. However, installing in columns is generally easier since the TallSlate TM strings will be connected in columns (see section on TallSlate TM wiring). Aesthetic Green Power, Inc.

17 See Figure 25 for an example roof section installed with TallSlate TM modules. Figure 25 TallSlate TM Modules Installed on Roof For integration with natural or ceramic slates, space link channels to allow at least 1/16 between each slate (Figure 26). Figure 26 TallSlate TM Modules Integrated with Natural Slate Note that there should always be a layer of natural or ceramic slate in the top row before the ridge cap is installed. Do not install the ridge cap directly over the TallSlate TM modules. Aesthetic Green Power, Inc. Page 17 of 21 Rev. 0 11/23/16

18 TallSlate TM Array Design Safety Series connections in Regions Following UL 1703 / ULC 1703 TallSlate TM modules are limited to series connections up to a maximum system voltage of 600 VDC. Do not exceed the maximum system voltage. Series Connections in Regions Following IEC TallSlate TM modules may be connected in series up to a maximum system voltage of 1000 VDC. Do not exceed the maximum system voltage. Parallel Connections and Overcurrent Protection TallSlate TM modules may be connected in parallel to produce desired current output. Each series string or module must be fused prior to combining with additional parallel strings if the resulting maximum reverse current exceeds the module series fuse rating of 10 Amps or other equipment may potentially back feed current into the panels. In the US, refer to NEC for additional detail. In Canada, refer to CSA C22.1, Safety Standard for Electrical Installations, Canadian Electrical Code, Part 1. In other regions, refer to the local electrical code on limitations to parallel connections and overcurrent protection. TallSlate TM Installation and Wiring Cables for module-to-module interconnections will be provided with your TallSlate TM modules. Always use the provided cables. If custom cables are required please contact the manufacturer or your local distributor for assistance. To install the TallSlate TM, simply slide the module into the wire clips at the bottom of the link channels. Before lowering the module onto the link channels, feed the cable up and under the horizontal wood batten in the next row. This allows the TallSlate TM to be easily connected to the TallSlate TM in the next row. Refer to Figure 27 for an example wiring diagram. Figure 27 Example Wiring Diagram Note: Wire lengths not to scale. This is a diagrammatic representation of field wiring, and is intended for illustrative purposes only. Aesthetic Green Power, Inc.

21 Figure 36 Incorrect (Red Gasket Visible) Figure 37 Correct (Red Gasket Not Visible) Resources For additional information on installing the Nu-lok TM Roofing System, please refer to the Nu-lok TM Installation Manual. However, note that there will be differences in the details of installation, mainly due to the difference in height of vertical counter battens. A typical Nu-lok TM installation without TallSlate TM modules uses a counter batten height of 3/8. A TallSlate TM installation requires a counter batten height of at least 1 to allow for the wires with connectors to be routed under the primary battens. This installation manual specifies a counter batten height of 1-1/2 so that standard sized lumber may be used for counter battens. Counter batten height may be reduced to 1, if necessary. However, note that the specifications of flashing given in this manual will change accordingly. Aesthetic Green Power, Inc. Page 21 of 21 Rev. 0 11/23/16
