(Continuous Load)(690.8(B)(1))

Wire Calculations
Wire ampacity calculated from 310.15(B)(16) & (17) as appropriate with ambient
temperature calculations from 310.15(B)(3)(c) and raceway fill adjustments from
310.15(B)(3)(a). Conduit on the roof shall be installed no less than 1" above the
roof deck. PV Circuit conductor ampacity is constrained using the 75°C column
with the continuous duty uprating or the 90°C column with the relevant ambient
temperature and raceway fill adjustments without the continuous duty uprating
per 690.8(B), whichever results with a larger wire size. Non-PV Circuit
Conductors use the ampacity in the 75°C column or the 90°C column with the
relevant ambient temperature and raceway fill adjustments, whichever is less
(110.14(C) & 310.15(A)(2)). The rating of the conductor after adjustments shall
be greater than, or equal to, the continuous duty uprated current.

BACKED UP LOADS CALCULATION:

THE MAXIMUM CURRENT FOR ALL LARGE APPLIANCES LOADS IS 40 A.

Powerwall 3 is a fully integrated solar and battery system, designed to accelerate the transition to sustainable energy. Customers
can receive whole home backup, cost savings, and energy independence by producing and consuming their own energy while
participating in grid services. Once installed, customers can manage their system using the Tesla App to customize system
behavior to meet their energy goals.
Powerwall 3 achieves this by supporting up to 20 kW DC of solar and providing 11.5 kW AC of continuous power per unit. It has
the ability to start heavy loads up to 185 A LRA, meaning a single unit can support the power needs of most homes. Powerwall 3
isdesignedformassproduction,fastandefcientinstallations,easysystemexpansion,andsimpleconnectiontoanyelectrical

The Tesla Backup Switch controls connection to the grid in a Powerwall system, and can be easily installed behind the utility
meter or in a standalone meter panel downstream of the utility meter.
The Backup Switch automatically detects grid outages, providing a seamless transition to backup power. It communicates
directly with Powerwall, allowing home energy usage monitoring from any mobile device with the Tesla app.

CONSUMER DISCLOSURE
From time to time, Sunrun Inc. (we, us or Company) may be required by law to provide to you
certain written notices or disclosures. Described below are the terms and conditions for providing
to you such notices and disclosures electronically through the DocuSign, Inc. (DocuSign)
electronic signing system. PLEASE READ THE INFORMATION BELOW CAREFULLY
AND THOROUGHLY, AND IF YOU CAN ACCESS THIS INFORMATION
ELECTRONICALLY TO YOUR SATISFACTION AND AGREE TO THESE TERMS AND
CONDITIONS, PLEASE CONFIRM YOUR AGREEMENT BY CLICKING THE 'I AGREE'
BUTTON AT THE BOTTOM OF THIS DOCUMENT.
Getting paper copies
At any time, you may request from us a paper copy of any record provided or made available
electronically to you by us. You will have the ability to download and print documents we send
to you through the DocuSign system during and immediately after signing session and, if you
elect to create a DocuSign signer account, you may access them for thirty (30) days after such
documents are first sent to you. After such time, if you wish for us to send you paper copies of
any such documents from our office to you, please request delivery of such paper copies from us
by following the procedure described below.
Withdrawing your consent
If you decide to receive notices and disclosures from us electronically, you may at any time
change your mind and tell us that thereafter you want to receive required notices and disclosures
only in paper format. How you must inform us of your decision to receive future notices and
disclosure in paper format and withdraw your consent to receive notices and disclosures
electronically is described below.
Consequences of changing your mind
If you elect to receive required notices and disclosures only in paper format, it will slow the
speed at which we can complete certain steps in transactions with you and delivering services to
you because we will need first to send the required notices or disclosures to you in paper format,
and then wait until we receive back from you your acknowledgment of your receipt of such
paper notices or disclosures. To indicate to us that you are changing your mind, you must
withdraw your consent using the DocuSign ‘Withdraw Consent’ form on the signing page of a
DocuSign envelope instead of signing it. This will indicate to us that you have withdrawn your
consent to receive required notices and disclosures electronically from us and you will no longer
be able to use the DocuSign system to receive required notices and consents electronically from
us or to sign electronically documents from us.
All notices and disclosures will be sent to you electronically
Unless you tell us otherwise in accordance with the procedures described herein, we will provide
electronically to you through the DocuSign system all required notices, disclosures,
authorizations, acknowledgements, and other documents that are required to be provided or made
available to you during the course of our relationship with you. To reduce the chance of you
inadvertently not receiving any notice or disclosure, we prefer to provide all of the required
notices and disclosures to you by the same method and to the same address that you have given
us. Thus, you can receive all the disclosures and notices electronically or in paper format through
the paper mail delivery system. If you do not agree with this process, please let us know as
described below. Please also see the paragraph immediately above that describes the
consequences of your electing not to receive delivery of the notices and disclosures
electronically from us.

This Letter is for the existing roof framing which supports the new PV modules as well as the attachment
of the PV system to existing roof framing. From the field observation report, the roof is made of
Composition Shingle roofing over roof plywood supported by 2X4 Rafters at 24 inches. The slope of the
roof was approximated to be 26 degrees.
After review and based on our structural capacity calculation, the existing roof framing has been
determined to be adequate to support the imposed loads without structural upgrades.
I certify that the PV module assembly including all attachments supporting it have been reviewed to be in
accordance with manufacturer's specifications. Capacity Calculations were done in accordance with
applicable building codes.

Limits of Scope of Work and Liability
The increase in seismic Dead weight as a result of the solar system is less than 10% of the existing structure
and therefore no further seismic analysis is required.
We have based our structural capacity determination on information in pictures and a drawing set titled PV
plans -RUBEN VELASCO. The analysis was according to applicable building codes, professional engineering
and design experience, opinions and judgments. The calculations produced for this structure's assessment
are only for the proposed solar panel installation referenced in the stamped plan set and were made
according to generally recognized structural analysis standards and procedures.

3. Will the PV array be flush mounted to the existing roof so that the plane of the
modules (panels) are parallel to the plane of the roof?
4. Will the PV system weigh maximum 4 pounds per square feet or less?
5. Will the PV system be installed where the modules do not overhang any roof edges
(such as eaves, gabled ends, ridges and hips)?
6. Will the PV system be installed with a space of 2” minimum to 10” maximum between
the underside of modules and the surface of the roof?
7. Will the PV system be installed without using any ballast system or counter-weight
system?
8. Will the anchors be installed with a maximum horizontal anchor spacing of 6 feet
and is this maximum horizontal spacing shown on the plans?
9. Will the minimum 5/16” lag screws be installed with a minimum of 2-1/2 inch
embedment into roof rafters (with pre-drilled holes) and is this minimum embedment
shown on the plans?
10. Are ALL the structural pages of the plans stamped and signed by a California
licensed professional engineer? (including project specific site plan, PV layout,
anchorage spacing, anchorage details and manufacturer’s PV support information.)
