To Whom It May Concern:
The following calculations are for the structural engineering design of the solar PV racking
system and its attachments. These calculations are valid only for the structural information
referenced in the stamped plan set. The verification of such info is the responsibility of
others. All solar mounting equipment shall be designed and installed per manufacturer's
approved installation specifications.
Limitations
Installation of the solar panels must be performed in accordance with manufacturer
recommendations. All work performed must be in accordance with accepted industry-wide
methods and applicable safety standards. The contractor shall notify EOR should any damage,
deterioration or discrepancies between the as-built condition of the structure and the
condition described in this letter be found. The use of solar panel support span tables
provided by others is allowed only where the building type, site conditions, site-specific
design parameters, and solar panel configuration match the description of the span tables.
The design of the solar panel racking (mounts, ballast, rails, etc.) and electrical engineering
are out of the scope of this work. Waterproofing around the roof penetrations is the
responsibility of the install contractor. EOR assumes no responsibility for improper
installation of the solar array.
If you have any questions, don't hesitate to contact.

ROOF PAD DETAILS
Minimum ratios by main roof types for application where friction coefficients must be met:
EPDM 1:1 Pads on each primary bay
TPO 1:4 Pads on 1 of every 4 primray bays
PVC 1:4 Pads on 1 of every 4 primary bays
Mineral cap N/A No pads required
NOTE
1. It is always an option to apply roof pads to all bays in an array even when not required
2. Roof pads are always applied 2 per bay (one on each ski to avoid unbalancing chasis).
3. When installing minimum roof pads for friction (at 1:4 ratio), apply 2 roof pads to every 4 primray bay staggering the offset between the rows:
1. Alternativey, install 2 roof pads to every other bay in a row of bays, then skip a row, and do it again
2. Skip any bays that have mechanical roof attachments(i.e., Anchor products, FlashLoc RM or OMG attachments).

Setbacks
For the wind tunnel recommendations in U-Builder to apply, the following setbacks should be observed/followed for
U-Builder wind design:
1. Modules should be placed a minimum of 3.00 ft from the edge of the building in any direction.
2. If the array is located near an obstruction that is 3.50 ft wide and 3.50 ft high or larger, the nearest
module of the array must be located a distance from the obstruction that is greater than or equal to the height of the obstruction. Exception: When
using ASCE 7-16/ASCE 7-22 Building Code and using the obstruction feature in the module editor to accurately model the size and location of
obstruction.
3. Installations within the setbacks listed above require site specific engineering.
4. The setbacks above are for wind and seismic. Fire access isles, mechanical equipment etc., may require larger setbacks than listed above.
Site Specific Engineering
Conditions listed below are beyond the current capabilities of U-Builder. Site specific engineering is required.
1. Building assumptions and design parameters outside of U-Builder assumptions
2. Wind tunnel testing reduction factors are not permitted by the Authority Having Jurisdiction (AHJ)
3. Seismic designs that fall outside SEAOC PV1-2012/ASCE 7-16/ASCE 7-22 SECTION 13.6.12 recommendations (>3% roof slope, or AHJ’s that
require shake table testing or non-linear site-specific response history analysis)
4. Signed and sealed site-specific calculations, layouts, and drawings
5. Building that is not enclosed and categorized as open structures, carport or others

ROOF PAD DETAILS
Minimum ratios by main roof types for application where friction coefficients must be met:
EPDM 1:1 Pads on each primary bay
TPO 1:4 Pads on 1 of every 4 primray bays
PVC 1:4 Pads on 1 of every 4 primary bays
Mineral cap N/A No pads required
NOTE
1. It is always an option to apply roof pads to all bays in an array even when not required
2. Roof pads are always applied 2 per bay (one on each ski to avoid unbalancing chasis).
3. When installing minimum roof pads for friction (at 1:4 ratio), apply 2 roof pads to every 4 primray bay staggering the offset between the rows:
1. Alternativey, install 2 roof pads to every other bay in a row of bays, then skip a row, and do it again
2. Skip any bays that have mechanical roof attachments(i.e., Anchor products, FlashLoc RM or OMG attachments).

1. Modules should be placed a minimum of 3.00 ft from the edge of the building in any direction.
2. If the array is located near an obstruction that is 3.50 ft wide and 3.50 ft high or larger, the nearest
module of the array must be located a distance from the obstruction that is greater than or equal to the height of the obstruction. Exception: When
using ASCE 7-16/ASCE 7-22 Building Code and using the obstruction feature in the module editor to accurately model the size and location of
obstruction.
3. Installations within the setbacks listed above require site specific engineering.
4. The setbacks above are for wind and seismic. Fire access isles, mechanical equipment etc., may require larger setbacks than listed above.
Site Specific Engineering
Conditions listed below are beyond the current capabilities of U-Builder. Site specific engineering is required.
1. Building assumptions and design parameters outside of U-Builder assumptions
2. Wind tunnel testing reduction factors are not permitted by the Authority Having Jurisdiction (AHJ)
3. Seismic designs that fall outside SEAOC PV1-2012/ASCE 7-16/ASCE 7-22 SECTION 13.6.12 recommendations (>3% roof slope, or AHJ’s that
require shake table testing or non-linear site-specific response history analysis)
4. Signed and sealed site-specific calculations, layouts, and drawings
5. Building that is not enclosed and categorized as open structures, carport or others
