We will not issue a building permit until you have read, initialed your understanding of each provision, signed, and returned this form to us at our official address indicated. An agent of the owner cannot execute this notice unless you, the property owner, obtain the prior approval of the permitting authority. OWNER'S ACKNOWLEDGMENT AND VERIFICATION OF INFORMATION (DIRECTIONS: Please read and initial each statement below to signify you understand or verify this information.) i_�1. I understand a frequent practice of unlicensed persons is to have the property owner obtain an "Owner- / Builder' building permit that erroneously implies that the property owner is providing his or her own labor and material personally. I, as an Owner - Builder, may be held liable and subject to serious financial risk for any injuries sustained by an unlicensed person and his or her employees while working on my property. My homeowner's insurance may not provide coverage for those injuries. I am willfully acting as an Owner - Builder and am aware of the limits of my insurance coverage for injuries to workers on my property. /�I understand building permits are not required to be signed by property owners unless they are responsible for the construction and are not hiring a licensed Contractor to assume this responsibility. � � I understand as an "Owner- Builder" I am the responsible party of record on the permit. I understand that I may protect myself from potential financial risk by hiring a licensed Contractor and having the permit filed in his or her name instead of my own. understand Contractors are required by law to be licensed and bonded in California and to list their license numbers on permits and contracts. +5_ nderstand if I employ or otherwise engage any persons, other than California licensed Contractors, and the total value of my construction is at least five hundred dollars ($500), including labor and materials, I may be considered an "employer' under state and federal law. �—,/� I understand if I am considered an "employer" under state and federal law, I must register with the state and federal government, withhold payroll taxes, provide workers' compensation disability insurance, and contribute to unemployment compensation for each "employee." I also understand my failure to abide by these laws may subject me to serious financial risk. �7. 1 understand under California Contractors' State License Law, an Owner - Builder who builds single - family residential structures cannot legally build them with the intent to offer them for sale, unless all work is performed by licensed subcontractors and the number of structures does not exceed four within any calendar year, or all of the work is performed under contract with a licensed general building Contractor. I understand as an Owner - Builder if I sell the property for which this permit is issued, I may be held liable for any financial or personal injuries sustained by any subsequent owner(s) that result from any latent construction defects in the workmanship or materials. OwnerBuildeYForm 2010.doc revised 04114110 understand I may obtain more information regarding my obligations as an "employer" from the Internal Revenue Service, the United States Small Business Administration, the California Department of Benefit Payments, and the California Division of Industrial Accidents. I also understand I may contact the California Contractors' State License Board (CSLB) at 1- 800 - 321 -CSLB (2752) or www.cs[b.ca.gov for more information about licensed contractors. am aware of and consent to an Owner - Builder building permit applied for in my name, and understand that I am the party legally and financially responsible for proposed construction activity at the site address listed above. I agree that, as the party legally and financially responsible for this proposed construction activity, I will abide by all applicable laws and requirements that govern Owner - Builders as well as employers. agree to notify the issuer of this form immediately of any additions, deletions, or changes to any of the information I have provided on this form. Licensed contractors are regulated by laws designed to protect the public. If you contract with someone who does not have a license, the Contractors' State License Board may be unable to assist you with any financial loss you may sustain as a result of a complaint. Your only remedy against unlicensed Contractors may be in civil court. It is also important for you to understand that if an unlicensed Contractor or employee of that individual or firm is injured while working on your property, you may be held liable for damages. If you obtain a permit as Owner - Builder and wish to hire Contractors, you will be responsible for verifying whether or not those Contractors are properly licensed and the status of their workers' compensation insurance coverage.

In case there is a gap, a fire and/or an electrical shock may occur. fully engaged ,�t CAUTION • Connect the required number of PV modules to meet the voltage specification for equipment used in the PV system. • Wire the output cable connectors so that they do not exert any force or pressure on the PV module's junction box. Attach the cable to the mounting framework using approved fasteners. • To extend the cable, use proper commercial cables and connectors that can withstand outdoor use for long periods. Select the appropriate cable size according to its length to avoid voltage drop. Follow the cable manufactuer's instructions. • The PV module has a pair of male and female waterproof connectors. For a series electrical connection, connect the positive ( +) connector of the first PV module to the negative ( -) connector of the following module. • Connect the output cable to the other equipment in the system correctly. • These modules employ UL Recognized connectors for the output wiring. Final output field wiring should be done with commercially available wiring products, such as Mitsubishi Electric Corporation Part Numbers "PV DWMC" or equivalent kit with Multi- Contact connectors, PV KST311(Male), PV KBT311(Female) and with minimum 14 AWG cables rated for 90 °C. These products will allow final system output wiring in accordance with the U.S. National Electrical Code, NFPA 70 -2002. Please refer to Article 690 of the NEC for additional guidance. MAINTENANCE Q WARNING • DO NOT touch live parts of wires, cables, connectors, or junction boxes. Be sure the circuit breaker is off, if is applicable. Always use appropriate safety equipment (insulated tools, insulating gloves, etc.). • Be sure to cover the front surface of the PV module with an opaque cloth or other material to block sunlight when working with the PV modules, because they generate high voltage when exposed to sunlight ANNUAL INSPECTION • Check if nuts, bolts of mounting framework are secure and not loose. Tighten all loose components. • Check connections of cables, grounding cables and connectors. • Check all electrical and mechanical connections for freedom from corrosion. • Check the ground resistance of metal parts such as the module frames and the mounting framework.

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 and Table 9 the Dead Load for your specific installation must be less than 5 psf, including modules and Unirac racldng 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 and footing spacing are interchangeable. The Total Design Load, P (psf) is determined using ASCE 7 -05 2.4.1 (ASD Method equations 3,5,6 and 7) by adding the Snow Loadl, S (psf), Design Wind Load, p,,,t (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 (psf) = LOD + I.OS1 ( downforce case 1) P (psf) = LOD + 1.Opnet (downforce case 2) P (psf) = 1. OD + 0.7551 + 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 uplift) The maximum Dead Load D (psf). is 5 psf based 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 of the 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 responsibilily to verify that the building structure is strong enough to support the point load forces. Table 10. Downforce Point Load Calculation Total Design Load (downforce) (max of case I, 2 or 3): P Module length perpendicular to rails: B Rail Span: L Downforce Point Load: Page 12 R Step 5: DetermixuE*:the Downforce Point Load, R (Ibs), at each connection based on rail span When designing the Unirac Flush Mount Installation, you must consider the downforce Point Load, R (lbs) on the roof structure. The Downforce, Point Load, R (lbs), is determined by multiplying the Total Design Load, P (psf) (Step 1) by the Rail Span, L (ft) (Step 3) and the Module Length Perpendicular to the Rails, B (ft) divided by two. R (lbs) = PLB 12 R = Point Load (lbs) P = Total Design Load (psf) L = Rail Span (ft) B = Module Length Perpendicular to Rails (ft) It is the installer's responsibility to verify that the building structure is strong enough to support the maximum point loads calculated according to Step 5. psf Step I X ft X ft Step 4 /2 lbs SolarMount Unirac Code - Compliant Installation Manual ::' U N I RAC Step 6: Determine the Uplift Point Load, R (lbs), at each connection based on rail span You must also consider the Uplift Point Load, R (lbs), to determine the required lag bolt attachment to the roof (building) structure.

SolarMount Unirac Code - Compliant Installation Manual ::ME ' U N I RAC [3.2.4] Installing SolarMount rails Keep rail slots free of roofing grit or other debris. Foreign matter will cause bolts to bind as they slide in the slots. Installing Splices: If your installation uses SolarMount splice bars, attach the rails together (Fig. 13) before mounting the rails to the footings. Use splice bars only with flush installations or those that use low- profile tilt legs. Although structural, the joint is not as strong as the rail itself. A rail should always be supported by more than one footing on both sides of the splice. (Reference installation manual 908, Splices /Expansion Joints.) Mounting Rails on Footings: Rails may be attached to either of two mounting holes in the L -feet (Fig. 14). Mount in the lower hole for a low profile, more aesthetically pleasing installation. Mount in the upper hole for a higher profile, which will maximize airflow under the modules. This will cool them more and may enhance performance in hotter climates. Slide the % -inch mounting bolts into the footing bolt slots. Loosely attach the rails to the footings with the flange nuts. Ensure that the rails are oriented to the footings as shown in Figure 8, 9, 11, or 12, whichever is appropriate. Aligning the Rail End: Align one pair of rail ends to the edge of the installation area (Fig. 15 or Fig. 16). The opposite pair of rail ends will overhang the side of the installation area. Do not trim them off until the installation is complete. Figure 13. Splice bars slide into the footing bolt slots of SolarMount rail sections. Clamping bolt slot � fi Mounting slots Footing \ bolt slot If the rails are perpendicular to the rafters (Fig. 15), either end of the rails Figure 14. Foot -to -rail splice attachment can be aligned, but the first module must be installed at the aligned end. If the rails are parallel to the rafters (Fig. 16), the aligned end of the rails must face the lower edge of the roof. Securely tighten all hardware after alignment is complete (20 ft lbs). Mount modules to the rails as soon as possible. Large temperature changes may bow the rails within a few hours if module placement is delayed. Edge of installation area Figure 15.

U N I RAC Unirac Code - Compliant Installation Manual SolarMount [3.2.5] Installing the modules Pre - wiring Modules: If modules are the Plug and Play type, no pre - wiring is required, and you can proceed directly to "Installing the First Module" below. If modules have standard J- boxes, each module should be pre -wired with one end of the intermodule cable for ease of installation. For safety reasons, module pre - wiring should not be performed on the roof. Leave covers off J- boxes. They will be installed when the modules are installed on the rails. Installing the First Module: In high - profile installations, the best practice would be to install a safety bolt (1/4" -20 x 1/2 ") and flange nut (both installer provided) fastened to the module bolt slot at the aligned (lower) end of each rail. It will prevent the lower end clamps and clamping bolts from sliding out of the rail slot during installation. If there is a return cable to the inverter, connect it to the first module. Close the J -box cover. Secure the first module with T -bolts and end clamps at the aligned end of each rail. Allow half an inch between the rail ends and the end clamps (Fig.18). Finger tighten flange nuts, center and align the module as needed, and securely tighten the flange nuts (10 ft lbs). Installing the Other Modules: Lay the second module face down (glass to glass) on the first module. Connect intermodule cable to the second module and close the J -box cover. Turn the second module face up (Fig. 17). With T- bolts, mid - clamps and flange nuts, secure the adjacent sides of the first and second modules. Align the second module and securely tighten the flange nuts (Fig. 19). For a neat installation, fasten wire management devices to rails with self - drilling screws. Repeat the procedure until all modules are installed. Attach the outside edge of the last module to the rail with end clamps. Trim off any excess rail, being careful not to cut into the roof. Allow half an inch between the end clamp and the end of the rail (Fig. 18) .

Use Arrangement A if the full width of the rails contacts the module. Otherwise use Arrangement B. Caution: If you choose Arrangement B, either (1) use the upper mounting holes of the L feet or (2) be certain that the L feet and clip positions don't conflict. If rails must be parallel to the rafters, it is unlikely that they can be spaced to match rafters. In that case, add structural supports — either sleepers over the roof or mounting blocks beneath it. These additional members must meet code; if in doubt, consult a professional engineer. Never secure the footings to the roof decking alone. Such an arrangement will not meet code and leaves the installation and the roof itself vulnerable to severe damage from wind. Leave enough room to safely move around the array during installation. The width of a rail- module assembly equals the length of one module. Note that L -feet may extend beyond the width of the assembly by as much as 2 inches on each side. The length of the assembly equals the total width of the modules.

They are also used for most ground mount installations. To ensure that the L -feet will be easily accessible during flush installation: • Use the PV module mounting holes nearest the ends of the modules. • Situate the rails so that footing bolt slots face outward. The single slotted square side of the L -foot must always lie against the roof with the double - slotted side perpendicular to the roof. Foot spacing (along the same rail) and rail overhang depend on design wind loads. Install half the L -feet: • if rails are perpendicular to rafters (Fig. 23), install the feet closest to the lower edge of the roof. • If rails are parallel to rafters (Fig. 24), install the feet for one of the rails, but not both. For the L -feet being installed now, drill pilot holes through the roofing into the center of the rafter at each lag screw hole location. Squirt sealant into the hole and onto the shafts of the lag screws. Seal the underside of the L -feet with a sealant. Securely fasten the L -feet to the building structure with the lag screws. Ensure that the L -feet face as shown in Figure 23 or Figure 24. Hold the rest of the L -feet and fasteners aside until the panels are ready for the installation.

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. 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.
