Electronic Record and Signature Disclosure
ELECTRONIC RECORD AND SIGNATURE DISCLOSURE
From time to time, MSH (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 system. Please read the
information below carefully and thoroughly, and if you can access this information electronically
to your satisfaction and agree to this Electronic Record and Signature Disclosure (ERSD), please
confirm your agreement by selecting the check-box next to ‘I agree to use electronic records and
signatures’ before clicking ‘CONTINUE’ within the DocuSign system.
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 the signing session and, if you
elect to create a DocuSign account, you may access the documents for a limited period of time
(usually 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, you will be charged a
$0.00 per-page fee. You may 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. Further, 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
Electronic Record and Signature Disclosure created on: 2/6/2020 1:48:36 PM
Parties agreed to: FRANCISCO GUTIERREZ
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.
How to contact MSH:
You may contact us to let us know of your changes as to how we may contact you electronically,
to request paper copies of certain information from us, and to withdraw your prior consent to
receive notices and disclosures electronically as follows:
To contact us by email send messages to: britney@my-smarthouse.com
To advise MSH of your new email address
To let us know of a change in your email address where we should send notices and disclosures
electronically to you, you must send an email message to us at britney@my-smarthouse.com and
in the body of such request you must state: your previous email address, your new email
address. We do not require any other information from you to change your email address.
If you created a DocuSign account, you may update it with your new email address through your
account preferences.
To request paper copies from MSH
To request delivery from us of paper copies of the notices and disclosures previously provided
by us to you electronically, you must send us an email to britney@my-smarthouse.com and in
the body of such request you must state your email address, full name, mailing address, and
telephone number. We will bill you for any fees at that time, if any.
To withdraw your consent with MSH
To inform us that you no longer wish to receive future notices and disclosures in electronic
format you may:
i. decline to sign a document from within your signing session, and on the subsequent page,
select the check-box indicating you wish to withdraw your consent, or you may;
ii. send us an email to britney@my-smarthouse.com and in the body of such request you must
state your email, full name, mailing address, and telephone number. We do not need any other
information from you to withdraw consent.. The consequences of your withdrawing consent for
online documents will be that transactions may take a longer time to process..
Required hardware and software
The minimum system requirements for using the DocuSign system may change over time. The
current system requirements are found here: https://support.docusign.com/guides/signer-guide-
signing-system-requirements.
Acknowledging your access and consent to receive and sign documents electronically
To confirm to us that you can access this information electronically, which will be similar to
other electronic notices and disclosures that we will provide to you, please confirm that you have
read this ERSD, and (i) that you are able to print on paper or electronically save this ERSD for
your future reference and access; or (ii) that you are able to email this ERSD to an email address
where you will be able to print on paper or save it for your future reference and access. Further,
if you consent to receiving notices and disclosures exclusively in electronic format as described
herein, then select the check-box next to ‘I agree to use electronic records and signatures’ before
clicking ‘CONTINUE’ within the DocuSign system.
By selecting the check-box next to ‘I agree to use electronic records and signatures’, you confirm
that:
You can access and read this Electronic Record and Signature Disclosure; and
You can print on paper this Electronic Record and Signature Disclosure, or save or send
this Electronic Record and Disclosure to a location where you can print it, for future

Expedited Permit Process for PV Systems - Micro-Inverter1
Expedited Permit Process for PV Systems
Micro-Inverter
The Solar America Board for Codes and Standards (Solar ABCs) Expedited Permit Pro-
cess provides a means to differentiate systems that can be permitted quickly and easily
due to their similarity with the majority of small-scale PV systems. Those systems with
unique characteristics may be handled with small additions to this Expedited Permit
Process or may require much more information, depending on the uniqueness of the
installation.
The following pages contain forms for the Micro-Inverter to use with the Expedited Per-
mit Process. The Standard String, AC Module, and Supply-Side Connection forms
are also available as interactive PDF files at www.solarabcs.org/permitting. In jurisdic-
tions that have adopted the Expedited Permit Process for PV Systems, these forms can
be filled out electronically and submitted in either printed form and via email. An elec-
tronic format is used so that the supplied information is standardized and legible for the
local jurisdiction.
Expedited Permit Process for PV Systems — Micro-Inverter 2
Expedited Permit Process for Small-Scale PV Systems
Micro-Inverter
The information in this guideline is intended to help local jurisdictions and contractors identify when PV system installations
are simple, needing only a basic review, and when an installation is more complex. It is likely that 50%-75% of all residential
systems will comply with these simple criteria. For projects that fail to meet the simple criteria, resolution steps have been
suggested to provide as a path to permit approval.
Required Information for Permit:
1. Site plan showing location of major components on the property. This drawing need not be exactly to scale, but it
should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings
with a 3’ perimeter space at ridge and sides may not need separate fire service review.
2. Electrical diagram showing PV array configuration, wiring system, overcurrent protection, inverter, disconnects,
required signs, and ac connection to building (see supplied standard electrical diagram).
3. Specification sheets and installation manuals (if available) for all manufactured components including, but not
limited to, PV modules, inverter(s), combiner box, disconnects, and mounting system.
Step 1: Structural Review of PV Array Mounting System
Is the array to be mounted on a defined, permitted roof structure? l Yes l No
If No due to non-compliant roof or a ground mount, submit completed worksheet for the structure WKS1.
Roof Information:
1. Is the roofing type lightweight (Yes = composition, lightweight masonry, metal, etc…)__________________________
____________________________________________________________________________________________________
If No, submit completed worksheet for roof structure WKS1 (No = heavy masonry, slate, etc…).
2. Does the roof have a single roof covering? l Yes l No
If No, submit completed worksheet for roof structure WKS1.
3. Provide method and type of weatherproofing roof penetrations (e.g. flashing, caulk).____________________________
Mounting System Information:
1. Is the mounting structure an engineered product designed to mount PV modules with no more than an 18” gap
beneath the module frames? l Yes l No
If No, provide details of structural attachment certified by a design professional.
2. For manufactured mounting systems, fill out information on the mounting system below:
a. Mounting System Manufacturer ___________Product Name and Model#________________________________
b. Total Weight of PV Modules and Rails ___________lbs
c. Total Number of Attachment Points____________
d. Weight per Attachment Point (b÷c)_________________lbs (if greater than 45 lbs, see WKS1)
e. Maximum Spacing Between Attachment Points on a Rail ______________inches (see product manual for
maximum spacing allowed based on maximum design wind speed)
f. Total Surface Area of PV Modules (square feet)_________________ ft2
g. Distributed Weight of PV Module on Roof (b÷f)_______________ lbs/ft2
If distributed weight of the PV system is greater than 5 lbs/ft2, see WKS1.
Step 2: Electrical Review of PV System (Calculations for Electrical Diagram)
In order for a PV system to be considered for an expedited permit process, the following must apply:
1. PV modules, utility-interactive inverters, and combiner boxes are identified for use in PV systems.
2. The PV array is composed of 4 series strings or less per inverter.
3. The total inverter capacity has a continuous ac power output 13,440 Watts or less
4. The ac interconnection point is on the load side of service disconnecting means (690.64(B)).
5. One of the standard electrical diagrams (E1.1, E1.1a, E1.1b, or E1.1c) can be used to accurately represent the PV
system. Interactive PDF diagrams are available at www.solarabcs.org/permitting.
Fill out the standard electrical diagram completely. A guide to the electrical diagram is provided to help the applicant
understand each blank to fill in. If the electrical system is more complex than the standard electrical diagram can effectively
communicate, provide an alternative diagram with appropriate detail.

Note to Building Official:
Based upon a review of the proposed plans I am confident that the
existing roof framing system is capable of safely supporting the additional
loads caused by the new solar photovoltaic energy system. The contractor
shall field verify that the existing roof structure is in its original permited
condition and verify that it can support the normal code required roof live
loads. Attached in this package are several calculations showing that the
roof members can support the additional weight of the solar array.
Furthermore, an analysis of the solar array's support for wind forces and a
seismic analysis of the existing structure are also included.
