Please write to publications@unirac.com. :FUNIRAC Unirac Code-Compliant Installation Manual SolarMount i. Installer's Responsibilities Please review this manual thoroughly before installing your SolarMount system. This manual provides (1) supporting documentation for building permit applications relating to Unirac's SolarMount Universal PV Module Mounting system, and (2) planning and assembly instructions for SolarMount SolarMount products, when installed in accordance with this bulletin, will be structurally adequate and will meet the structural requirements of the IBC 2009, ASCE 7-05 and California Building Code 2010 (collectively referred to as "the Code"). Unirac also provides a limited warranty on SolarMount products (page 26). SolarMount is much more than a product. It's a system of engineered components that can be assembled into a wide variety of PV mounting structures. With SolarMount you'll be able to solve virtually any PV module mounting challenge. It's also a system of technical support: complete installation and code compliance documentation, an on-line SolarMount Estimator, person-to-person customer service, and design assistance to help you solve the toughest challenges. This is why SolarMount is PVs most widely used mounting system. The installer is solelv responsible for: • Complying with all applicable local or national building codes, including any that may supersede this manual; e Ensuring that Unirac and other products are appropriate for the particular installation and the installation environment; • Ensuring that the roof, its rafters, connections, and other structural support members can support the array under all code level loading conditions (this total building assembly is referred to as the building structure); • Using only Unirac parts and installer-supplied parts as specified by Unirac (substitution of parts may void the warranty and invalidate the letters of certification in all Unirac publications); • Ensuring that lag screws have adequate pullout strength and shear capacities as installed; • Verifying the strength of any alternate mounting used in lieu of the lag screws; • Maintaining the waterproof integrity of the roof, including selection of appropriate flashing; • Ensuring safe installation of all electrical aspects of the PV array; • Ensuring correct and appropriate design parameters are used in determining the design loading used for design of the specific installation. Parameters, such as snow loading, wind speed, exposure and topographic factor should be confirmed with the local building official or a licensed professional engineer. 0 Page 2 SolarMount Unirac Code-Compliant Installation Manual :i:UN I RAC Part I. Procedure to Determine the Design Wind Load [1.1.] Using the Simplified Method - ASCE 7-05 The procedure to determine Design Wind Load is specified by the American Society of Civil Engineers and referenced in the International Building Code 2009. For purposes of this document, the values, equations and procedures used in this document reference ASCE 7-05, Minimum Design Loads for Buildings and Other Structures. Please refer to ASCE 7-05 if you have any questions about the definitions orprocedures presented in this manual. Unirac uses Method 1, the Simplified Method, for calculating the Design Wind Load for pressures on components and cladding in this document. The method described in this document is valid for flush, no tilt, SolarMount Series applications on either roofs or walls. Flush is defined as panels parallel to the surface (or with no more than 3" difference between ends of assembly) with no more than 10" space between the roof surface, and the bottom of the PV panels. This method is not approved for open structure calculations. Applications ofthese procedures is subject to thefollowing ASCE 7-05 limitations: 1. The building height must be less than 60 feet, h < 60. See note for determining h in the next section. For installations on structures greater than 60 feet, contact your local Unirac Distributor. 2. The building must be enclosed, not an open or partially enclosed structure, for example a carport. 3. The building is regular shaped with no unusual geometrical irregularity in spatial form, for example a geodesic dome. 4. The building is not in an extreme geographic location such as a narrow canyon or steep cliff. 5. The building has a flat or gable roof with a pitch less than 45 degrees or a hip roof with a pitch less than 27 degrees. 6. If your installation does not conform to these requirements please contact your local Unirac distributor or a local professional engineer. If your installation is outside the United States or does not meet all of these limitations, consult a local professional engineer or your local building authority. Consult ASCE 7-05 for more clarification on the use of Method I. Lower design wind loads may be obtained by applying Method II from ASCE 7-05. Consult with a licensed engineer if you want to use Method II procedures. The equation for determining the Design Wind Load for components and cladding is: pnet (psf) = AKzd pnet3O pnet (Pd) = Design Wind Load X = adjustmentfactorfor building height and exposure category Kzt = Topographic Factor at mean roof height, h (ft) I = Importance Factor pnet30 (Psf) = net designwind pressurefor Exposure B, at height = 30feet, I = 1.0 You will also need to know the following information: Basic Wind Speed = V (mph), the largest 3 second gust of wind in the last 50 years. h (ft) = total roof heightfor.flat roof buildings or mean roofheight for pitched roof buildings RoofPitch (degrees) This manual will help you determine: Effective Wind Area (sf) = minimum total continuous area of modules being installed (Step 2) Roof Zone = the area of the roof you are installing the pv system according to Step 3. RoofZone Dimension = a (ft) (Step 3) Exposure Category (Step 6) [1.2.] Procedure to Calculate Total Design Wind The procedure for determining the Design Wind Load can be broken into steps that include looking up several values in different tables. Table 5 has been provided as a worksheet for the following 9 steps (page 8) Step 1: Determine Basic Wind Speed, V (mph) Determine the Basic Wind Speed, VOMph) by consulting your local building department or locating your installation on the maps in Figure 1, page 4. Step 2: Determining Effective Wind Area Determine the smallest area of continuous modules you will be installing. This is the smallest area tributary (contributing load) to a support or to a simple-span of rail. That area is the Effective Wind Area, the total area of the fewest number of modules on a run of rails. If the smallest area of continuous modules exceeds 100 sq ft, use 100 sq ft (See Table 2). If less, round down to values available in Table 2. 0 P.Ke 3 :F UNIRAC Unirac Code-Compliant Installation Manual SolarMount a:k 4,%42,9 ......../.

Step 5: Determine the Topographic Factor, K,t For the purposes of this code compliance document, the Topographic Factor, Kzt, is taken as equal to one (1), meaning, the installation is surrounded by level ground (less than 10% slope). If the installation is not surrounded by level ground, please consult ASCE 7-05, Section 6.5.7 and the local building authority to determine the Topographic Factor. Step 6: Determine Exposure Category (B, C D) Determine the Exposure Category by using the following definitions for Surface Roughness Categories. SURFACE ROUGHNESS C: has open terrain with seat- tered obstructions having heights generally less than 30 feet. This category includes flat open country, grasslands, and all water surfaces in hurricane prone regions. SURFACE ROUGHNESS D: has flat, unobstructed areas and water surfaces outside hurricane prone regions. This category includes smooth mud flats, salt flats, and unbroken ice. The ASCE/SEI 7-05 defines wind surface roughness categories as follows: SURFACE RoUGHNESS B: is urban and suburban areas, wooded areas, or other terrain with numerous closely spaced obstructions having the size of single family dwellings.

Procedure to Select Rail Span and Rail Type [2.1.] Using Standard Beam Calculations, Structural Engineering Methodology The procedure to determine the Unirac SolarMount series rail type and rail span uses standard beam calculations and structural engineering methodology. The beam calculations are based on a simply supported beam conservatively, ignoring the reductions allowed for supports of continuous beams over multiple supports. Please refer to Part I for more information on beam calculations, equations and assumptions. If beams are installed perpendicular to the eaves on a roof steeper than a 4/12 pitch in an area with a ground snow load greater than 30psf, then additional analysis is required for side loading on the roof attachment and beam. In using this document, obtaining correct results is dependent upon the following: 1. Obtain the Snow Load for your area from your local building official. 2. Obtain the Design Wind Load, pnet. See Part I (Procedure to Determine the Design Wind Load) for more information on calculating the Design Wind Load. 3. Please Note: The terms rail span and footing spacing are interchangeable in this document. See Figure 3 for illustrations. 4. To use Table 8, the Dead Load for your specific installation must be less than 5 psf, including modules and Unirac racking systems. If the Dead Load is greater than 5 psf, see your Unirac distributor, a local structural engineer or contact Unirac. The following procedure will guide you in selecting a Unirac rail for a flush mount installation. It will also help determine the design loading imposed by the Unirac PV Mounting Assembly that the building structure must be capable of supporting. Step 1: Determine the Total Design Load Figure 3. Rail span andfooting spacing are interchangeable. The Total Design Load, P (P€f) is determined using ASCE 7-05 2.4.1 (ASD Method equations 3,5,6 and 7) by adding the Snow Loadi, S (psf), Design Wind Load, pnet (psf) from Part I, Step 9 and the Dead Load (psf). Both Uplift and Downforce Wind Loads calculated in Step 9 of Part 1 must be investigated. Use Table 7 to calculate the Total Design Load for the load cases. Use the maximum absolute value of the three downforce cases and the uplift case for sizing the rail. Use the uplift case only for sizing lag bolts pull out capacities (Part II, Step 6). Use the following equations or Table 7. P Gsf) = 1.OD + 1.09 (downforce case 1) P (psf) = 1.OD + 1.Opnet (downforce case 2) P Oqf) = 1.OD + 0.759 + 0.75pnet (downforce case 3) P (psf) = 0.6D + 1.Opnet (uplift) D = Dead Load (psf) S = Snow Load (psf) pnet = Design Wind Load (psf) (Positive for downforce, negative for uptift) Ike maximum Dead Load, D (Dsf), is S vsfbased on market research and internal data. 1 Snow Load Reduction - The snow load can be reduced according to Chapter 7 of ASCE 7-05. The reduction is a function ofthe roof slope, Exposure Factor, Importance Factor and Thermal Factor. Please refer to Chapter 7 of ASCE 7-05 for more information.

Longer spans produce fewer wall or roof penetrations. However, longer spans create higher point load forces on the building structure. A point load force is the amount of force transferred to the building structure at each connection. It is the installer's responsibilitv to verify that the building structure is strong enough to SUPDOrt the Doint load forces. Table 10.

Align the edges of the modules and snug them together (Fig. 21, page 22). Trim the rails to the total width of the modules to be mounted. Place a rail adjacent to the outer mounting holes. Orient the footing bolt slot outward. Place a clip slot adjacent to the mounting holes, following the arrangement you selected earlier. Assemble the clips, mounting bolts, and flange nuts. Torque the flange nuts to 10 foot-pounds. [3.3.4] Installing the module-rail assembly Bring the module-rail assembly to the installation site. Keep rail slots free of debris that might cause bolts to bind in the slots. Consider the weight of a fully assembled panel. Unirac recom mends safety lines whenever lifting one to a roof. Align the panel with the previously installed L-feet. Slide 3/8 inch L-foot mounting bolts onto the rail and align them with the L-feet mounting holes. Attach the panel to the L-feet and finger tighten the flange nuts. Rails may be attached to either of two mounting holes in the footings (Fig. 25). • Mount in the lower hole for a low, more aethetically pleasing installation. • Or mount in the upper hole to maximize a cooling airflow under the modules. This may enhance perfor- mance in hotter climates. slots Footing Mounting slots Flange bolt slot 7476 Figure 25. Leg-to-rail attachment Adjust the position of the panel as needed to fit the installa- tion area. Slide the remaining L-feet bolts onto the other rail, attach L-feet, and finger tighten with flange nuts. Align L-feet with mounting holes previously drilled into the roof. Install lag bolts into remaining L-feet as described in "Laying out and installing L-feet" above. Torque all footing flange nuts to 30 foot-pounds. Verify that all lag bolts are securely fastened. .3 0 Page 24 SolarMount Unirac Code-Compliant Installation Manual :FUNIRAC [3.4] Installing SolarMount with grounding clips and lugs Clips and lugs are sold separately.

It is designed to collect, store and upload a wide array of energy data allowing both system installers and owners to efficiently manage solar assets. The LGate 101 can monitor nearly any type of solar energy system. Regardless of inverter or panel type, it can measure energy production with a high degree of accuracy. As a datalogger, it has a variety of digital and analog inputs enabling direct communication with third-party devices such as inverters and meteorological sensors. Performance data is aggregated and uploaded automatically to the Locus Energy Smart Monitoring website which provides custom tools and analytics to all project stakeholders. DATA COLLECTION The LGate uses a hard-wired voltage reference and current transformers (CTs) to measure power. There are inputs for up to three CTs allowing the LGate to measure both solar energy generation and whole-house electrical consumption. It can also gather data from up to 16 third-party devices simultaneously which is collected via RS485 and Modbus RTU protocols. All data feeds are stored in non-volatile memory and then uploaded with unique identifiers to provide maximum fl exibility as to how the data is presented online. NETWORK CONNECTIVITY The LGate 101 is a plug and play device supporting a multitude of connectivity options. It can communicate over Ethernet, powerline carrier (PLC), or cellular networks. Hard-wired Ethernet is the preferred connection method, but if this is unavailable, the LGate features a built in 110V outlet for easy installation of a PLC adapter. Data is transmitted only in outbound sessions over open ports requiring no additional network or firewall configuration. The connection and commissioning process is further simplified by the LGate's LED lights which indicate communication status without installers having to log in or call home.
