IMmc Code-Compliant Installation Manual SunFrame i. Installer's Responsibilities Please review this manual thoroughly before installing your SunFrame system. This manual provides (1) supporting documentation for building permit applications relating to Unirac's SunFrame Universal PV Module Mounting system, and (2) planning and assembly instructions for SunFrame SunFrame products, when installed in accordance with this bulletin, will be structurally adequate and will meet the structural requirements of the IBC 2006, IBC 2003, ASCE 7- 02, ASCE 7-05 and California Building Code 2007 (collectively referred to as "the Code"). Unirac also provides a limited warranty on SunFrame products (page 24). SunFrame offers finish choices and low, clean lines that become as natural a part of a home as a skylight. It delivers the installation ease you've come to expect from Unirac. Whether for pitched roofs or parking roof structures, SunFrame was designed from the outset to promote superior aesthetics. Modules are flush mounted in low, gap-free rows, and visible components match clear or dark module frames. The installer is solely responsible for: • Complying with all applicable local or national building codes, including any that may supersede this manual; • 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; and • 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. SunFrame Unirac Code-Compliant Installation Manual HT U N111A C 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 2006. 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 or procedures 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, SunFrame 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 of these procedures is subject to the following 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, a local professional engineer or Unirac 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 n from ASCE 7-05. Consult with a licensed engineer if you want to use Method n procedures. The equation for determining the Design Wind Load for components and cladding is: Pnet (psf) = Pnet (.psf) = Design Wind Load A = adjustment factor for height and exposure category Kx = Topographic Factor at mean roof height, h (ft) I = Importance Factor Pneao (psf) = net design wind pressure for Exposure B, at height = 30,1=1 You will also need to know the following information: Basic Wind Speed = V (mph), the largest 3 second gust of wind in thelastSOyears. h (ft) = total roof height for flat roofbuildings or mean roof height for pitched roofbuildings Effective Wind Area (sf) = minimum total continuous area of modules being installed Roof Zone = the area of the roof you are installing the pv system according to Figure 2, page 5. Roof Zone SetbackLength = a(ft) Roof Pitch (degrees) Exposure Category [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. Step 1: Determine Basic Wind Speed, V (mph) Determine the Basic Wind Speed, V (mph) by consulting your local building department or locating your installation on the maps in Figure 1, page 4. Step 2: Determining Elective 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.

Values are nominal design 3-second gust wind speeds at 33 feet above ground for Exposure Category C. 110(49)120(54) Step 3: Determine Roof/Wall Zone The Design Wind Load will vary based on where the installation is located on a roof. Arrays may be located in more than one roof zone. Using Table 1, determine the Roof Zone Setback Length, a (ft), according to the width and height of the building on which you are installing the pv system. Table I.

Step 5: Determine the Topographic Factor, Ka For the purposes of this code compliance document, the Topographic Factor, Ka, is taken as equal to one (1), meaning, the installation is on level ground (less than 10% slope). If the installation is not on 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 Exposure Categories. The ASCE/SEI7-05* defines wind exposure categories as follows: EXPOSURE B is urban and suburban areas, wooded areas, or other terrain with numerous closely spaced obstructions having the size of single family dwellings. EXPOSURE c has open terrain with scattered obstruc- tions having heights generally less than 30 feet. This category includes flat open country, grasslands, and all water surfaces in hurricane prone regions. EXPOSURE D has flat, unobstructed areas and water surfaces outside hurricane prone regions. This catego- ry includes smooth mud flats, salt fiats, and unbroken ice. Also see ASCE 7-05 pages 287-291 for further explanation and explanatory photographs, and confirm your selection with the local building authority. •1* UN IRAC Unirac Code-Compliant Installation Manual SunFrame Step 7: Determine adjustment factor for height and ' exposure category, A Using the Exposure Category (Step 6) and the roof height, h (ft), look up the adjustment/actor/or height and exposure in Table 4.

Procedure to Select Rail Span and Rail Type [2.1.] Using Standard Beam Calculations, Structural Engineering Methodology The procedure to determine the Unirac SunFrame 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. Infusing 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 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 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 Loadi, S (psf), Design Wind Load, pn«t (psf) from Part I, Step 9 and the Dead Load (psf). Both Uplift and Downforce Wind Loads calculated in Step 9 of Part 2 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). P (psf) = 2.0D + 2.0S1 (downforce case 1) P (psf) = l.OD + l.Opnet (downforce case 2) P(psf) = 1.0D + 0.7SS1 + 0.75pnet (downforce case 3) P (psf) = 0.6D + l.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 had 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. Figure 3. Rail span and footing spacing are interchangeable. 10 Note: Modules must be centered symmetrically on the rails (+/- 2*), as shown in Figure 3. If this is not the case, call Unirac for assistance.

Step 2: Determine the Distributed Load on the rail, w(plf) Determine the Distributed Load, w (plf), by multiplying the module length, B (ft), by the Total Design Load, P (psf) and dividing by two. Use the maximum absolute value of the three downforce cases and the Uplift Case. We assume each module is supported by two rails. w = Distributed Load (pounds per linear foot, plf) B = Module Length Perpendicular to Rails (ft) P = Total Design Pressure (pounds per square foot, psf) Step 3: Determine Rail Span/L-Foot Spacing Using the distributed Zoad, w, from Part II, Step 2, look up the allowable spans, L, for SunFrame. There are two tables, L-Foot SunFrame Series Rail Span Table and Double L-Foot SunFrame Series Rail Span Table.

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 tfaq In^fll^J'8 responsibility to verify that thq bufldjpg structure is strong enough to support the point load forces. Step 5: Determine 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 (Ibs) on the roof structure. The Downforce, Point Load, R (Ibs), 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). R(lbs) = PLB R = Point Load (Ibs) 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. 12 SunFrame Unirac Code-Compliant Installation Manual BT U NIR AC Table 10.

Laying out the installation area and planning for material conservation. B. Installing footings and rails, beginning with the lowest row and moving up the roof. C. Placing modules and cap strips, beginning with the highest row and moving down the roof. The following illustrated steps describe the procedure hi detail. Before beginning, please note these important considerations. Footings must be lagged into structural members. Never attach them to the decking alone, which leaves both the array and roof susceptible to severe damage. f\ For array widths or lengths greater than 45 feet, see instruction manual 908.1 * »• concerning thermal expansion issues. Sample layout, illustrated in Figure 4 Assumptions: 12 modules (60' x 36 '), arranged in 3 rows of 4 modules Array width = 144" (36" module width x 4 modules per row) Array length = 180" (60 'module length x 3 rows) + 3 ' (IVa" end rail width x 2 rails) + 1V4" (a/4" between-module rail width x 2 rails) = 184%" 1. Laying out the installation area Always install SunFrame rails perpendicular to rafters. (These instructions assume typical rafters that run from the gutter to the peak of the roof; If this is not the case, contact Unirac.) Rails are typically mounted horizontally (parallel to the lower edge of the roof), and must be mounted within 10 degrees of horizontal. Leave adequate room to move safely around the array during installation. During module installation, you will need to slide one module in each row about a foot beyond the end of the rails on one side. Using the number of rows and the number of modules per row in your installation, determine the size of your array area following Figure 6. Arr lenj i .

Installing the lowest row of L-feet and rail In the lowest row, it is not necessary to use L-foot adjusting sliders, even if you plan to use them in subsequent rows. Install L-feet directly onto low profile roofing material such as asphalt shingles or sheet metal. (For high profile roofs, such as tile or shake, use optional standoffs with flashing to raise L-feet. L-feet must be flush with or above the highest point of the roof surface.) L-feet can be placed with the double-slotted side against the roof surface (as in Fig. 7) or with the single-slotted side against the roof (which increases air circulation beneath modules). Module-to-roof dimensions are listed on page 15 for both ar- rangements. If you are using L-foot adjusting sliders, you must use f\ the short side of the the L-foot against the roof in the .first row. See Figure 9 below. If you are using both L-foot adjusting sliders and standoffs, see the upper box on page 11. Install the first row of L-feet at the lower edge of the instal- lation area (Fig. 8). Ensure feet are aligned by using a chalk line. (A SunFrame rail can also be used as a straight edge.) Position the L-feet with respect to the lower edge of the roof as illustrated in Figures 7 and 8. Always lag into slot nearest the bend in the L-foot Lower edge of installation area Figure 7. Placement of first L-foot raw. Drill a pilot hole through roof into the center of the rafter at each L-foot lag screw hole location. Apply weatherproof sealant into the hole and onto shafts of the lag screws. Seal the underside of the L-feet with a suitable weatherproof sealant. Fasten the L-feet to the roof with the lag screws. If the double slotted sides of the L-feet are against the roof, lag through the slot nearest the bend in the L-foot (Figs. 7 and 8). Figure 8. L-foot orientation. Cut the rails to your array width, being sure to keep rail slots free of roofing grit or other debris. If your .instal- lation requires splices, assemble them prior to attaching L-feet (see "Footing and splicing require- ments," p. 11, and "Material planning for rails and cap strips," p. 13). Slide the 3/s-inch mounting bolts into the footing slots. If more than one splice is used on a rail, slide L-foot bolt(s) into the footing • slot(s) of the interior rail segment(s) before splicing. Loosely attach the rails to the L-feet with the flange nuts. Ensure that rails are oriented with respect to the L-feet as shown in Figure 9. Align the ends of the rail to the edge of the installation area. Ensure that the rail is straight and parallel to the edge of the roof. Then tighten the lag screws. Figure 9- L-foot orientation in conjunction with L-foot adjusting sliders. The sliders include two utility slots to secure module wiring, combiner boxes, and other system components. 17 SF U NIR AC Unirac Code-Compliant Installation Manual SunFrame Using standoffs with L Two-piece aluminum standoffs maybe used with footing sliders, although flashings may not be available to cover the entire length of the slider. Use the bases of the standoffs only in the lowest row. In subsequent rows, attach the shaft •foot adjusting sliders of each standoff to the slider using the slider's 3/s-inch hex- head bolt. Note that L-feet are positioned long side up on the lowest rows and with long side down in subsequent rows— in the same manner as an installation with no standoffs. With standoffs of equal length, orient L-foot to compensate/or height difference. If the standoff supporting the lowest rail is 1 inch taller than the standoffs on the footing sliders, place both L-feet in the same orientation—either both long side up or both short side up. r-L-foot This example assumes a rail seven times the length of the footing spacing (A). A splice may be located in any of the shaded areas. If more than one splice is used, be sure the combination does not violate Requirements 5,6, or 7. Footing and splicing requirements The following criteria are required for sound installations. While short sections of rail are structurally permissible, they can usually be avoided by effective planning, which also pro- motes superior aesthetics. See "Material planning for rails and cap strips" (p. 13). The installer is solely responsiblefor ensuring that the roof and its structural members can support the array and its live loads. For rail lengths exceeding 48 feet, thermal expansion joints may be necessary. Please contact Unirac. 1. Footing spacing along the rail (A in illustration above) is determined by wind loading (see pp. 5-8, especially step 4). Foot spacing must never exceed 48 inches. 2. Overhang (B) must be no more than half the length of the maximum footing spacing (A). For example, if Span A is 32 inches, Overhang B should not exceed 16 inches. Modules should always be fully supported by rails. In other words, modules should never overhang rails. This is especially critical when supporting the short side of a non-rectangular module. When a rail supports a pair of non- rectangular modules by themselves (right), it must be supported by at least two L-feet. The rail should be at least 14 and no more than 24 inches long, which will likely require a stringer between rafters to ensure proper footings. 3. Do not locate a splice in the center third of the span between two adjacent feet. 4. In a spliced length of rail, all end sections must be sup- ported by no less than two L-feet. 5. All interior rail sections must be supported by no less than one L-foot. 6. ulterior rail sections supported by only one L-foot must be adjacent, on at least one side, to a rail section sup- ported by no less than two L-feet. . 7. Rail sections longer than half the footing spacing re- quire no fewer than two L-feet. Non-rectangular modules 18 SunFrame Unirac Code-Compliant Installation Manual gT UNIRAC 3. Laying out and installing the next row of L-feet With L-fieet only: Position the second row of L-feet in accor- dance with Figure 10. Ensure that you measure between the lower bolt hole centers of each row of L-feet. Install the second row of L-feet in the same manner and orientation as the first row, but leave the lag screws a half turn loose. Be aware of the set-up time of your sealant; the L-feet will not be fully tight- ened until Step. 4. With L-foot adjusting sliders: Use a chalk line to mark the position of the slider center holes of the next row. The illustra- tion below provides spacing guidelines. The length of the module (A in Fig. 11) includes any protrusions, such as lips or pan-head screws in its frame. Attach and seal L-foot adjusting slider: Install lower lag first, footing bolt next, and upper lag last. Attach an L-foot with its short side up to each slider.

If you are using L-foot adjusting sliders, this spacing between rows places L-feet at the center of their adjustment range. 4. Installing the second rail With L-feet only (Fig. 12): Install and align the second rail in the same manner and orientation as the first rail. After rail alignment, tighten the rail mounting bolts to between 30 and 35 foot-pounds. Lay one module in place at one end of the rails, and snug the upper rail (Fig. 12) toward the lower rail, leaving no gap between the ends of the modules and either rail. (If pan-head screw heads represent the true end of the modules, be sure the screw heads touch the rails on both ends.) Tighten the lag screw on that end. Slide the module down the rails, snugging the rails and tightening the remaining lag screws as you go. With L-foot adjusting sliders: Install rails on first and second rows of L-feet. Verify spacing by placing a module onto the rails at several points along the row. Adjust L-foot positions as needed. Lag screw '. (half turn loose) Figure 12. Position and secure top rail. 5. Installing remaining L-feet and rails Install the L-feet and the rails for the remaining rows, follow- ing Steps 3 and 4. You may use the same module to space all the rows. When complete, confirm that: All rails are fitted and aligned. All footing bolts and lag screws are secure. The module used for fitting is resting (but not se- cured) in the highest row. 19 ST U NIR A C Unirac Code-Compliant Installation Manual SunFrame Material planning for rails and cap strips Preplanning material use for your particular array can prevent structural or aesthetic problems, particularly those caused by very short lengths ofraU or cap strip. This example illustrates one approach. Structural requirements for rails are detailed in "Footing and splicing requirements" (p.ll). Structurally, cap strips require: • A screw in every prepunched hole (which occur every 8 inches, beginning 4 inches from the ends of the rails). assemblies and cap strip assemblies need to be cut and spliced from 192-inch sections of rail and cap strip. The example illustrates one means of doing so, without violating structural requirements or aesthetic goals. Rail segments come from five 192-inch lengths, lettered A thru E. Rail A, for example, is cut into two 96-inch segments, with one segment spliced into each of the first two rails. Similarly, five 192-inch cap strips are designated V through Z. All cap strip segments are cut at the midpoint between • One screw 4 inches or less from the each end of every rail segment. Wherever there is no prepunched hole within 4 inches of an end of a segment, drill a ^-inch hole 2 inches from the end of the segment and install a cap strip screw. (In most cases, you can avoid this situation with good material planning.) prepunched screw holes. For each rail, start with the cap strip segment that crosses the array center line, and position over the center line so that the appropriate holes are spaced equally on either side. Position each cap strip onto its rail and mark its trim point Remove and trim before final mounting. Preliminary footing and splice positions must be Structural requirements always take precedence, but usually good planning can also achieve both material conservation and superior aesthetics. This example conserves material and achieves two specific aesthetic goals: • Cap strip screws must align across the rails. « End screws must be equidistant from both sides of the array. checked against structural requirements in "Footing A and splicing requirements" (p.ll). In this example, /\ the center of the array is offset 2 inches from the center £—1 rafter. This prevents rail splices BD (3rd rail) and CE (4th rail) from falling too close to the center of the spans between footings (Requirements, p. 11). Because foot- ings are not visible from ground level, there is negligible aesthetic loss. The example assumes an array of three rows, each holding five modules 41 inches wide.

Securing the first module Gather sufficient lengths of cap strip to cover the length of the first rail. For maximum visual appeal and material conservation see "Material planning for rails and cap strips" (p. 13). Slide the first module into final position at one end of the array. Lay the remaining modules in the top row, leaving a gap about a foot wide between the first and second modules (Fig. 13). The temporary gap allows the installer to place one of his feet between modules. He can access the section of the cap strip he needs to secure while leaning toward the peak of the roof. For the time being, the last module may overhang the rail by up to one third its width. Attach the end of the cap strip with the cap strip screws (Fig. 13, inset), so that the upper end of the first module is secure. not install second cap strip until lower Figure 13. Begin cap strip installation. The structural integrity of your array requires that cap strip screws fully engage the threaded rail Use the cap strip screws supplied with your cap strips. Any substitute screws must be ¥4-20 Type F thread cutting (18-8 stainless steel) and the correct length. See Table 4 (pg. IS) to match screw length to the size cap strip in your installation. Every cap strip segment must have a cap strip screw 4 inches or less from each end. If the nearest predrilled hole falls more than 4 inches from any end, drill a %-inc/r hole 2 inches from the end and install an additional screw. Wherever it is necessary to make a new cap strip hole, drill a 'A-inch hole before installing the cap strip screw. 7. Installing the remaining modules in the top row Slide the next module into final position and install the screws to secure it (Fig. 14). For a neat installation, use cable ties to attach excess wiring to the rail beneath the flanges. Unirac's cable ties can be attached to the SunFrame rail by drilling a Wi-inch hole in the rail and pushing the end of the tie into the hole. Continue the process until all modules in the top row are in final place and secured from the top. When complete, every prepunched hole in the cap strip will be secured by a screw, and the top end of the first row of modules will be secure. 8. Installing the remaining modules row by row Repeat Steps 6 and 7 for the remaining rows (Fig. 15). Each subsequent cap strip will secure the tops to the modules being installed and the bottoms of the modules in the row above. Place the final cap strip in the lowest rail, securing the bottom of the lowest module row. Figure 14. Position and secure modules one by one. Figure 15. As modules slide into place, the stepping gap shifts, always allowing access to the section of cap strip being secured. 21 8T U NIR A C Unirac Code-Compliant Installation Manual SunFrame 9.

The answer depends on the orientation of your L-feet and the length of your standoffs, if used. See the illustration ap- propriate to your installation. How can I seal the roof penetration required when standoffs are lagged below the roofing material? Many types and brands of flashing can be used with Sun- Frame. Unirac offers an Oatey® "No-Calk" flashings for its steel standoffs and Oatey® or Unirac flashings for its aluminum two-piece standoffs. See our SunFrame Pro-Pak Price List.

Rails. Modules are supported between SunI r;ime rails, not on top of them. The array is lower to the roof, enhancing its integrated appearance. A threaded slot atop the rail makes for quick and secure module mounting. Should it ever be- come necessary, replace modules easih. 2. Cap Strips. SunI rame cap strips hold modules securely. Because the strips are pre-punched, you never have to drill. 3. Splices. Hidden splices are used to create long rows of modules. If required, install them to allow thermal expan- sion. Consult SunI rame installation instructions for details. www.unirae.com See our SunFrame page for additional information: pricing, an installation manual appropriate to your building code, additional on-site images, and a great new tool for determining and costing minimum component requirements for your unique job. 4. L-feet. Serrated I.-feet attach directly to asphalt shingle roofs or rest on adjusting sliders or standoffs. 5. L-foot adjusting sliders. I,-fect can be easily adjusted along fixed sliders to ensure that rails fit snuggh against the modules. 6. Standoffs and flashings. 'i\vo-piece standoffs speed installation on tile roofs. \Ve offer six flashing choices for our aluminum or steel standoffs. 7. End caps. UV resistant black end caps neatly finish off the installation. Module compatibility Use SunFrame with PV modules from these major manufacturers: BP Solar, Evergreen, GE Energy, Isofoton, Kaneka, Kyocera, Mitsubishi, Photowatt, Schott Solar, Sanyo, Sharp, SolarWorld (Shell), SunPower, SunWize, and Uni-Solar.
