I March 13, 2012 Jeff Randall Solar Agent Power Trip Energy 83 Denny Way Port Townsend, WA 98368 Dear Mr Randall: This is to report on my analysis of the McMahon Residence roof system at 602 S Alder Street in Port Angeles. This was done to satisfy City requirement for a licensed engineer's opinion on structural adequacy of this roof to support new solar panels. This analysis is for panels on the east facing roof. As you know, on October 26, 2011, I completed a similar analysis for solar panels on the south facing roof. The Code required loading for this location and this type of roof system is 25 pounds per square foot snow load; top and bottom chord dead loads of 7 and 10 psf, respectively. The solar panels add an additional 5 psf dead load. Panel locations are shown on the roof framing plan you provided. The array dimensions are 8 -feet (parallel to trusses) by 20 -feet (perpendicular to trusses). The array starts about 4 -feet down from the ridge. You also provided geometry of the affected trusses, panel attachment details, and engineer letters of verification for panel attachment adequacy. Our work was strictly related to the roof system framing. Engineering calculations for this analysis are attached. Our analysis indicates that the existing trusses are adequate as is. Modifications are not required, provided the existing steel splice plates are of sufficient size. I understand that you have inspected these plates and that they are all larger the minimum size required. Our work also considered the existing 5 foot window header. We believe that the approximate 4.3% end reaction load increase is small enough to have no affect on this header.

At this time you should do a layout on the roof confirming everything on the drawing will fit as it is intended. Any irregularities should be noted now, so that you can deal with them simply on install day. The quality of the roofing should be determined, so that any repairs or replacement can happen before or in conjunction with the installation. On a composition roof it is important to know as much as possible about: the manufacturer, the age of roof, the type of substrate (plywood or oriented strand board [OSB]), the rafter size, the spacing and span, the age of roof structure, who roofed it, who built it, etc. Photos should be taken of all of the roof variables and associated with the job file for any future reference either short term or long. Typically the building owner can look in a file and find the composition manufacturer. If not, take a piece to the roofing yard, they can usually recognize the maker and the rough vintage. It is then easy to obtain the written manufacturer's installation instructions for the roofing materials you are dealing with. The manufacturer's instructions will spell out exactly what does and does not void the warranty of their roofing product. Most have a clause about roof temperature. This is commonly missed, but can easily be noted if you read the instructions. Officially, the roofing manufacturer's instructions supersede our instructions, as our product is weaving into theirs. It is also important to have their instructions in the job file, for any future reference. If the manufacturer cannot be found, there is obviously no warranty in place. On a roof that has a material and labor warranty in place (new roof), it is recommended to at least consult the roofer of record. Often the roofing contractor will void the labor portion of their warranty if another trade modifies their work. Give the roofing contractor the option of handling the roofing modifications, or at least give them the opportunity to inspect and approve the modifications you make. There will be fees to this roofer, but if it maintains the labor warranty it should be good money spent. Product Selection Product Includes The Composition Mount is intended to fit within most composition and wood shingle The units are sold in 12 packs. Each 12 pack includes the mounting hard roof systems, but not all. Specifically it is sized to fit within a standard 5" to 5 1/2" ware and the mount with flashing to install 12 mounts, with written instruc- row or course. To confirm that the Comp Mount will match your roof, measure the tions. course exposure of your roof. The "exposed" surface course height should measure Alternative Attachment Methods no more than 5 3/4 If it turns out the roof tiles are a non standard size greater than 5 3/4 the alternative method is to use a Quick Mount Shake Mount The Composition Mount is intended to be attached into a lumber rafter. instead. In this case, follow the directions for the Quick Mount Mounts are usually laid out based on the location of the rafters. In some Shake Mount. (See Compostion Mount Instructional cases it is desired to place a mount where there is no rafter. In this case it Video at quickmountpv.com/tech.php, then is possible to place a block between rafters, then lag into the block. In the Shake Composition Video: case of metal rafters, lumber blocking the rafters is a solution, but should be done per the building's engineer of record. 5 "Typical Shared Rail 5" Rule On a shared rail system, where the mounts must be in an exact spot, it is important to make sure the unit is flashed properly. Normally the vertical placement is guided by the exposed front edge of the shingle. If (on a 5" High Definition Comp Presidential exposure comp) the flashing is flush with this, then you have 5" of flashing Irregular surface If the penetration lands in a low between two highs, it is best to shim over course 1, 5" of flashing under course 2, and 2" of flashing under cours- the low under the flashing with extra asphalt to level out the surface. es 2 and 3. This is important because if there is a vertical joint in course 2 the water cannot find its way under the flashing because it extends under Irregular tooth pattern If the shingles have a tooth pattern wherein the bottom edge course 3. When the flashing must be shifted to catch a shared rail, it is ad- jogs up and down to give it a higher profile look, it is important to understand that the vised to shift the mount up the roof only, leaving less flashing over course 1, excess shingle that hangs lower than the rest of the shingle is for looks only.

If a tooth interferes with the mount block, cut the tooth advised to move down a whole course and then shift up accordingly. off. QUICK MOUNT PV Sealants COURSE 3 It is important to put a compatible sealant into any and all holes drilled into z _3 a roof.

IBC There are two questions that must be asked when adding anything to a roof. P International j'n 1. Can the roof building foundation handle the additional load? N ational Building l 2. What is to keep the new load from blowing away? Roofing Code State Contractors Building It is assumed that a licensed solar installer can answer these questions. If he she Association can't, he she will need to find somebody that can. A licensed engineer is the easiest Code solution. Some of the racking manufacturers have guides to calculating a code compli- Q Asphalt ant install as well. Many variables must be considered and determined to complete the Roofing PN calculation. The spacing between mounts has the variables of: strength of rail, distance Manufacturers International AHJ Residential between parallel rails, cantilever of modules over rails, pull out strength of mount, slope Association of roof, height of roof, wind zone, roof type, structural integrety of roof framing, etc. The code only values in the variables above that we can provide is pull out strength and shear of Authority 1 mount.

This manual contains important safety, installation, operation, service, and A\ A maintenance information that you should understand in its entirety prior to installing, wiring, or using Silicon Energy PV modules. Do not connect or disconnect modules under load. Silicon Energy PV modules are designed to produce direct current (DC) electricity from light. Modules wired in series, parallel, or series parallel A configurations can produce electrical shock great enough to cause damage to property, injury, or death by electrocution. Prior to installing, wiring, or using Silicon Energy PV modules you should: fully understand and practice electrical, building, and fire safety fully understand PV /solar electric systems have knowledge of, experience with, and follow all local and national building and electrical codes (see National Electric Code -NEC Article 690) Product Handling Only knowledgeable and trained professionals should install these modules. In some jurisdictions, licensed contractors may be required for installation. Multiple panels connected in series can produce high voltages which are potentially hazardous. Do not wire the modules during wet, damp or high wind conditions. Cascade PV modules are constructed with a tempered glass front and back. Although durable, it is glass. Handle with care. Do not set the module down in such a way that the exposed edges of glass are supporting any weight. Areas on the module most prone to damage are the exposed edges of glass and the leads. Pay particularly close attention to protecting these areas from damage while installing, servicing, or maintaining the module(s). Do not stand on, step on, or kneel on the module. Do not drop the module, drop objects onto the module, or set heavy loads on the module. Avoid any sharp impacts between objects and the module. Always treat the output wires of the modules as a potential source of electricity and electrical shock. Photovoltaic modules do not have to be connected to a circuit to generate DC current. Each installer should wear safety gear including eye, head, hand and fall protection. The modules are heavy and must be handled properly to avoid injury to persons and damage to product. It is recommended that two people lift and move modules due to their size and weight. Protect person and module from falls when installing above ground. Inspect modules for damage, particularly to the leads. Never install a damaged module. Use extreme caution when handling a module with a damaged lead. PLEASE NOTE, AS PER SECTION 48, UL 1703: PV module power is affected by both temperature and light: Colder temperatures can increase the voltage and power. Reflection of light from snow, water, or other surfaces can increase the current and power. Do not artificially concentrate light on the module(s). Under normal conditions, a PV module is likely to experience conditions that produce more current and /or voltage than reported at standard test conditions (STC). Accordingly, the values of I and V marked on this module should be multiplied by a factor of 1.25 when determining component voltage ratings, conductor ampacities, fuse sizes, and size of controls connected to the PV for output.

Module Installation The following general instructions are provided as the minimum required for safety. For detailed mounting instructions see the Silicon Energy Cascade System Installation Guide. 3.1. Electrical Installation Safety A. Solar modules and their interconnection cables pass direct current (DC) and can be a voltage source when exposed to light or under load. DC can arc across gaps and may cause injury or death if wiring is connected or disconnected when current is present. Modules must never be connected or disconnected under Load. Before (dis)connecting modules, the circuit must be broken at another point using a rated device intended for that purpose (e.g. breaker). A short circuited module or array exposed to light will produce current that should be treated as a load. Fully cover all modules with an opaque material before connecting or disconnecting modules. 3.2: Electrical Installation Requirements All installations must comply with the National Electric Code (NEC) and all applicable local codes. Provide 15 amp maximum series fuse rating for over current protection. Secure all wires and protect from mechanical damage. For all installer supplied wiring, use a minimum USE -2 sunlight- resistant wire or PV wire with a maximum conductor temperature of at least 90C (wet) such as found in the Table 2. Table 2. Wire Specifications Gauge Mfr Part Max Conductor Purpose (AWG) Mfr Number Temperature Supplied by Module Output 14 Tyco 1986166 -Y 90C min (wet) SiE to Disconnect 14 Tyco 1986166 -Y 90C min (wet) Installer or SiE to Disconnect 12 Tyco 1986165 -Y 90C min (wet) Installer or SiE to Disconnect 10 Tyco 1986164 -Y 90C min (wet) Installer or SiE to Disconnect 6 Tyco 1986274 -Y 90C min (wet) Installer or SiE to Ground 14 to 6 N/A N/A 90C min (wet) Installer The module output leads are 14 AWG and come with factory installed connectors (see Table 3). When making the final connection of the array to the positive and negative disconnects, use only UL recognized solar connectors such as Tyco SOLARLOK connectors. The metallic crimp supplied within the connector may only be applied using the approved Tyco crimping tool. 4 www.Silicon- Ener Cascade PV Module Manual Rev. 3 Table 3.

Grounding Requirements This module does not have a,continuous frame. Therefore, for safety and to protect the system from lightning, both edge guards of the module must be grounded. Connect to earth ground using the center PEM studs and the flange nuts provided. When the module is properly installed with Silicon Energy's Cascade Installation System, the module will be grounded to the installation structure and no additional grounding of the module will be necessary. The ground conductors must be a minimum of 6AWG if installed in such a way that it is exposed to mechanical damage. Ground conductors which are protected from mechanical damage must be a minimum of 14AWG. 3.4. Mechanical Installation Requirements Modules must be fastened securely to installation systems intended for PV applications. Wind and snow loads not to exceed 125 psf. For module applications requiring greater strength Silicon Energy must be consulted to protect the module warranty and an engineer must be used to design the installation means. Engineering verification is recommended to ensure a structurally sound roof or mounting structure. When roof mounted, module and installation system must be over a fire resistant roof covering rated for the application. The Cascade PV Modules must be mounted with edge guards parallel to the fall line of the roof or mounting structure. They are designed to be rotated to have the positive lead on either side, but must not be mounted with the edge guards running perpendicular to the fall line. As always, good practice should be used when installing Silicon Energy Cascade PV Modules: Mount to maximize solar exposure and minimize or eliminate shading. Modules may be mounted at any angle from 0 to 90 however the Cascade Installation System does have minimum installation angles. See the Silicon Energy Cascade System Installation Guide for more details. When installing these modules the following should be considered: Avoid low angle installations to prevent buildup up dust, debris, snow and ice and to utilize the "frameless" feature of these modules to best advantage. Always maximize ventilation behind modules for cooling. A minimum clearance of 1.5 inches between mounting surface and modules is required to maintain fire rating. 5 www.Silicon-Ener Cascade PV Module Manual Rev. 3 22 C© Ga LOMPORTERLMN rEE; u December 14, 2010 CPL Job S09- 0176 -03 Miriam Ginsberg Ron Wright Associates 2003 Western Ave., Ste. 300 u Seattle, WA 98121 RE: Maloney Heights Solar Panel Permit: Attachment of Solar Panels to Structure Dear Miriam: The solar panel supplier has indicated that the solar panels will be attached to the structure with 5/16" diameter by 3" long lag bolts attached to the roof framing with (4) attachment points for each module. The loading on the solar panels is based on 100 mph basic wind speed with exposure C and a seismic design category D -1. Wind uplift controls the attachment of the panels to the structure with the controlling uplift cladding pressure equal to 35 psf. The panel supplier proposed attachment to the structure is acceptable. If any lag bolts do not land on roof framing blocking should be placed between roof framing pieces with a Simpson A35 located at the ends of the blocking piece.

J October 26, 2011 Jeff Randall Solar Agent Power Trip Energy 83 Denny Way Port Townsend, WA 98368 Dear Mr Randall: This is to report on my analysis of the McMahon Residence roof system at 602 S Alder Street in Port Angeles. This was done to satisfy the City requirement for a licensed engineer's opinion on structural adequacy of this roof to support new solar panels. As you know, the roof must hold 25 pounds per square foot snow load, the existing dead load and an additional 5 psf for solar panels. Panel locations are shown on the roof framing plan you provided. You also provided geometry of the existing trusses, panel attachment details, and engineer letters of verification for panel attachment adequacy. Our work was strictly related to the roof system framing. Engineering calculations for this analysis are attached. We find that the roof system will support the above loads upon completion of minor reinforcing. This reinforcing includes: Installation of an additional roof rafter on the top chord of each "Truss E" that supports a solar panel. The new rafter should be a 2x4 x 6 -feet long, centered on the existing 2x4 rafter. It should be fastened with two rows of 10d nails (0.128" x 3 spaced at 6" on center. Installation of one additional top chord on "Truss Cx2 The new top chord should be a 2x4 x 7 -feet 6- inches long (minimum), centered on the existing 2x4 top chord. It should be fastened with two rows of 10d nails (0.128" x 3 spaced at 6" on center. This modification assumes that "Truss Cx2" has 2x6 bottom chords. The information you provided was not clear on this aspect. If this is not true, please let me know because additional reinforcing will be needed. As you know, one end of "Truss Cx2" is supported by "Truss Bx3. Our analysis shows that "Truss Bx3" is adequate without additional reinforcing. This assumes 2x8 bottom chords for "Truss Bx3 If this is not true, please let me know because additional reinforcing will be needed.

(AME) has completed load- testing Quick Mount PV system anchors for shear and tensile strength. The purpose of our testing was to evaluate the tensile and shear Toad capacity of the Quick Mount PV system in a high density (Douglas Fir) and a low density wood (Cedar). SAMPLE DESCRIPTION Twelve (12) 12 "x12" samples were delivered to our laboratory on 10- 16 -08; six each for Douglas Fir. and Cedar. A copy of the installation instructions is provided in Appendix A. Typical sample photo is provided in Appendix B. PROCEDURES RESULTS Since an acceptance criterion (AC) has not been developed for this product, the samples were tested under the direction of Mr. Yamil Moya, P.E. with ICC -ES, and in general accordance with applicable procedures outlined in ASTM D 1761 and AC 13. a. Tensile Strength Three samples each of the two types of wood were tested for tensile strength on October 24 27, 2008 using a United Universal testing machine. Samples were rigidly attached to the testing machine and a tensile load was applied to the 5/16 "x6" hanger bolt at a displacement rate 0.1 inches per minute without shock until failure. Detailed results are provided in Table I. Based on these results, the average tensile strength of the hanger bolt in Douglas Fir and Cedar wood species were determined to be 3934 lbs and 2214 lbs, respectively. d Dun Page 1 of 10 Stuart Wentworth Project Number 108443C QUICK MOUNT PV Quick Mount PV Load Testing October 28. 2008 b. Shear Strength Three samples each of the two types of wood were tested for shear strength on October 24 27. 2008 using a United Universal testing machine. Samples were rigidly attached to the testing machine and a shear load was applied to the 2-1/4"x1 -A14"x1-1/4" aluminum mount at a displacement rate 0.1 inches per minute without shock until failure. Detailed results are provided in Table 11, Based on these results. the alierage shear strength attic hanger bolt in Douglas Fir and Cedar wood species were determined to be 4365 lbs and 3313 lbs. respectively.

Do not connect or disconnect modules under load. Silicon Energy PV modules are designed to produce direct current (DC) electricity from light. Modules wired in series, parallel, or series parallel configurations can produce electrical shock great enough to cause damage'to property, injury, or death by electrocution. Prior to installing, wiring, or using Silicon Energy PV modules you should: fully understand and practice electrical, building, and fire safety fully understand PV /solar electric systems have knowledge of, experience with, and follow all local and national building and electrical codes (see National Electric Code -NEC Article 690) Product Handling Only knowledgeable and trained professionals should install these modules. In some jurisdictions, licensed contractors may be required for installation. Multiple panels connected in series can produce high voltages which are potentially hazardous. Do not wire the modules during wet, damp or high wind conditions. Cascade PV modules are constructed with a tempered glass front and back. Although durable, it is glass. Handle with care. Do not set the module down in such a way that the exposed edges of glass are supporting any weight.' Areas on the module most prone to damage are the exposed edges of glass and the leads. Pay particularly close attention to protecting these areas from damage while installing, servicing, or maintaining the module(s). Do not stand on, step on, or kneel on the module. Do not drop the module, drop objects onto the module, or set heavy loads on the module. Avoid any sharp impacts between objects and the module. Always treat the output wires of the modules as a potential source of electricity and electrical shock. Photovoltaic modules do not have to be connected to a circuit to generate DC current. Each installer should wear safety gear including eye, head, hand and fall protection. The modules are heavy and must be handled properly to avoid injury to persons and damage to product. It is recommended that two people lift and move modules due to their size and weight. Protect person and module from falls when installing above ground. Inspect modules for damage, particularly to the leads. Never install a damaged module. Use extreme caution when handling a module with a damaged lead. PLEASE NOTE, AS PER SECTION 48, UL 1703: PV module power is affected by both temperature and light: Colder temperatures can increase the voltage and power. Reflection of light from snow, water, or other surfaces can increase the current and power. Do not artificially concentrate light on the module(s). Under normal conditions, a PV module is likely to experience conditions that produce more current and/or voltage than reported at standard test conditions (STC). Accordingly, the values of L. and V marked on this module should be multiplied by a factor of 1.25 when determining component voltage ratings, conductor ampacities, fuse sizes, and size of controls connected to the PV for output. Refer to Section 690 of the National Electric Code (NEC 690.8) for another additional multiplying factor of 1.25 (80% derating) which may be applicable. The electrical characteristics are within -10% of the indicated values of I V and P max under standard test conditions (irradiance of 100 mW /cm AM 1.5 spectrum, and a cell temperature of 25 °C 77 °F) 2 www.Silicon- Energy.com Cascade PV Module Manual Rev. 3 1.

Module Installation The following general instructions are provided as the minimum required for safety. For detailed mounting instructions see the Silicon Energy Cascade System Installation Guide. 3.1. Electrical Installation Safety Solar modules and their interconnection cables pass direct current (DC) and can be a AA■ A voltage source when exposed to light or under load. DC can arc across gaps and may cause injury or death if wiring is connected or disconnected when current is present. Modules must never be connected or disconnected under load. Before (dis)connecting modules, the circuit must be broken at another point using a rated device intended for that purpose (e.g. breaker). A short circuited module or array exposed to light will produce current that should be treated as a load. Fully cover all modules with an opaque material before connecting or disconnecting modules. 3.2. Electrical Installation Requirements All installations must comply with the National Electric Code (NEC) and all applicable local codes. Provide 15 amp maximum series fuse rating for over current protection. Secure all wires and protect from mechanical damage. For all installer supplied wiring, use a minimum USE -2 sunlight- resistant wire or PV wire with a maximum conductor temperature of at least 90C (wet) such as found in the Table 2. Table 2. Wire Specifications Gauge Mfr Part Max Conductor Purpose (AWG) Mfr Number Temperature Supplied by Module Output 14 Tyco 1986166 -Y 90C min (wet) SiE to Disconnect 14 Tyco 1986166 -Y 90C min (wet) Installer or SiE to Disconnect 12 Tyco 1986165 -Y 90C min (wet) Installer or SiE to Disconnect 10 Tyco 1986164 -Y 90C min (wet) Installer or SiE to Disconnect 6 Tyco 1986274 -Y 90C min (wet) Installer or SiE to Ground 14 to 6 N/A N/A 90C min (wet) Installer The module output leads are 14 AWG and come with factory- installed connectors (see Table 3). When making the final connection of the array to the positive and negative disconnects, use only UL recognized solar connectors such as Tyco SOLARLOK connectors. The metallic crimp supplied within the connector may only be applied using the approved Tyco crimping tool. 4 www.Silicon- Energy.com Cascade PV Module Manual Rev. 3 Table 3.

Grounding Requirements This module does not have a continuous frame. Therefore, for safety and to protect the system from lightning, both edge guards of the module must be grounded. Connect to earth ground using the center PEM studs and the flange nuts provided. When the module is properly installed with Silicon Energy's Cascade Installation System, the module will be grounded to the installation structure and no additional grounding of the module will be necessary. The ground conductors must be a minimum of 6AWG if installed in such a way that it is exposed to mechanical damage. Ground conductors which are protected from mechanical damage must be a minimum of 14AWG. 3.4. Mechanical Installation Requirements Modules must be fastened securely to installation systems intended for PV applications. Wind and snow loads not to exceed 125 psf. For module applications requiring greater strength Silicon Energy must be consulted to protect the module warranty and an engineer must be used to design the installation means. Engineering verification is recommended to ensure a structurally sound roof or mounting structure. When roof mounted, module and installation system must be over a fire resistant roof covering rated for the application. The Cascade PV Modules must be mounted with edge guards parallel to the fall line of the roof or mounting structure. They are designed to be rotated to have the positive lead on either side, but must not be mounted with the edge guards running perpendicular to the fall line. As always, good practice should be used when installing Silicon Energy Cascade PV Modules: Mount to maximize solar exposure and minimize or eliminate shading. Modules may be mounted at any angle from 0 to 90 however the Cascade Installation System does have minimum installation angles. See the Silicon Energy Cascade System Installation Guide for more details. When installing these modules the following should be considered: Avoid low angle installations to prevent buildup up dust, debris, snow and ice and to utilize the "frameless" feature of these modules to best advantage. Always maximize ventilation behind modules for cooling. A minimum clearance of 1.5 inches between mounting surface and modules is required to maintain fire rating. 5 www.Silicon- Energy.com Cascade PV Module Manual Rev. 3 C ®ltAG[H111.0l IiPORTERWIXi r• ESN u December 14, 2010 CPL Job S09- 0176 -03 u Miriam Ginsberg Ron Wright Associates 2003 Western Ave., Ste. 300 Seattle, WA 98121 RE: Maloney Heights. Solar Panel Permit: Attachment of Solar Panels to Structure Dear Miriam: The solar panel supplier has indicated that the solar panels will be attached to the structure with 5/16" diameter by 3" long lag bolts attached to the roof framing with (4) attachment points for each module. The loading on the solar panels is based on 100 mph basic wind speed with exposure C and a seismic design category D -1. Wind uplift controls the attachment of the panels to the structure with the controlling uplift cladding pressure equal to 35 psf. The panel supplier proposed attachment to the structure is acceptable. If any lag bolts do not land on roof framing blocking should be placed between roof framing pieces with a Simpson A35 located at the ends of the blocking piece.
