GENERAL NOTES
1. THE CONTRACTOR/INSTALLER OF THE SOLAR PV SYSTEM OVER EXISTING ROOF SHALL CONFIRM TO OSHA REQUIREMENTS DURING THE CONSTRUCTION PHASE. JOB SAFETY AND
CONSTRUCTION PROCEDURES ARE THE SOLE RESPONSIBILITY OF THE CONTRACTOR/INSTALLER.
2. IN CASE OF CONFLICT BETWEEN STRUCTURAL DRAWINGS AND ELECTRICAL DRAWINGS, THE MOST RIGID REQUIREMENTS SHALL GOVERN.
3. THE CONTRACTOR/INSTALLER SHALL VERIFY ALL EXISTING BUILDING INFORMATION SHOWN (DIMENSIONS, ROOF TOP PROJECTIONS, ETC.) AND NOTIFY THE ENGINEER OF ANY
DISCREPANCIES PRIOR TO INSTALLATIONS OF PV SYSTEM.
4. THE CONTRACTOR/INSTALLER SHALL VERIFY AND COORDINATE EXISTING OPENINGS, ROOF TOP UNITS, VENT PIPES, ETC. SHOWN ON DRAWINGS. IF THERE IS A DISCREPANCY BETWEEN
DRAWINGS, IT IS THE CONTRACTORS/INSTALLER'S RESPONSIBILITY TO NOTIFY ENGINEER PRIOR TO PERFORMING THE WORK.
5. ALL CONSTRUCTION IS TO BE PERFORMED IN STRICT CONFORMANCE WITH ALL APPLICABLE TOWN,COUNTY & STATE REGULATIONS AND/OR ANY OTHER GOVERNING BODIES.
6. DO NOT SCALE THESE DRAWINGS, USE DIMENSIONS. CONTRACTOR MUST CONDUCT ROOF SURVEY TO VERIFY DIMENSIONS SHOWN ON PLAN PRIOR TO INSTALLATION. IF THERE IS A
DISCREPANCY IT IS CONTRACTOR/INSTALLER'S RESPONSIBILITY TO NOTIFY THE ENGINEER IMMEDIATELY.
7. EACH MODULE TO BE GROUNDED USING THE SUPPLIED CONNECTION POINT PER MANUFACTURER'S REQUIREMENTS. ALL SOLAR MODULES, EQUIPMENT, AND METALLIC COMPONENTS ARE
TO BE BONDED. IF THE EXISTING GROUNDING ELECTRODE SYSTEM CAN NOT BE VERIFIED OR IS ONLY METALLIC WATER PIPING, IT IS THE CONTRACTOR'S RESPONSIBILITY TO INSTALL A
SUPPLEMENTAL GROUNDING ELECTRODE.
8. ALL PLAQUES AND SIGNAGE REQUIRED BY THE LATEST EDITION OF NATIONAL ELECTRICAL CODE. LABEL SHALL BE METALLIC OR PLASTIC, ENGRAVED OR MACHINE PRINTED IN A
CONTRASTING COLOR TO THE PLAQUE. PLAQUE SHALL BE UV RESISTANT IF EXPOSED TO SUNLIGHT.
9. DC CONDUCTORS SHALL BE RUN IN RMC AND SHALL BE LABELED, "CAUTION DC CIRCUIT" OR EQUIV. EVERY 5 FT.
10. EXPOSED NON-CURRENT CARRYING METAL PARTS OF ELECTRICAL EQUIPMENT SHALL BE GROUNDED IN ACCORDANCE WITH 250.134 OR 250.136(A).
11. CONFIRM LINE SIDE VOLTAGE AT ELECTRIC UTILITY SERVICE PRIOR TO CONNECTING INVERTER. VERIFY SERVICE VOLTAGE IS WITHIN INVERTER VOLTAGE OPERATIONAL RANGE.
12. OUTDOOR EQUIPMENT SHALL BE NEMA-3R RATED OR BETTER.
13. ELECTRICAL CONTRACTOR TO PROVIDE CONDUIT EXPANSION JOINTS AND ANCHOR CONDUIT RUNS AS REQUIRED PER NEC.
14. ALL WIRING MUST BE PROPERLY SUPPORTED BY DEVICES OR MECHANICAL MEANS DESIGNED AND LISTED FOR SUCH USE, AND FOR ROOF-MOUNTED SYSTEMS, WIRING MUST BE
PERMANENTLY AND COMPLETELY HELP OFF OF THE ROOF SURFACE. CEC 110.2 - 110.4 / 300.4
15. ALL ROOF PENETRATIONS MUST BE FLASHED. SIMPLY CAULKING DOES NOT SUFFICE.
16. PV INSTALLATION SHALL COMPLY WITH ARTICLE 690 OF 2022 CEC, CRC REQUIRES THAT SMOKE ALARMS AND CARBON MONOXIDE ALARMS ARE RETROFITTED INTO EXISTING DWELLING,
THE REQUIRED SMOKE ALARMS AND CARBON MONOXIDE DETECTORS SHALL BE LOCATED AS REQUIRED PER SECTION R314 & R315 WITHIN THE CALIFORNIA RESIDENTIAL CODE.
17. NEW ELECTRICAL EQUIPMENT SHALL BE LOCATED AT LEAST THREE (3) FEET FROM GAS METER OR GAS SHUT-OFF VALVES. CPC1208.7.1; CEC 110.26

A jobsite observation of the condition of the existing framing system was performed by an audit team of CS&E as a request from Laguna
Consulting Engineers. All review is based on these observations and the design criteria listed below and only deemed valid if the provided
information is true and accurate.
The scope of this report is strictly limited to an evaluation of the fastener attachment, underlying framing, and supporting structure with the
additional loading due to the installation of the solar PV panels. The design of racking (rail spans, mounting hardware, etc.), PV panels and all
other structure is by others and shall be per the specified design criteria. Laguna Consulting Engineers assumes no responsibility for improper
installation of PV panels, racking, or waterproofing. Prior to starting construction, contractor shall verify the framing sizes, spacings, and spans
noted in the stamped plans and this letter and notify the Engineer of Record of any discrepancies noted. This review relies on the roof’s
structural system having been originally designed and constructed in accordance with the building code requirements and having been
maintained to be in good condition.
ROOF 1: Adequate to support the imposed loading - No structural upgrades required

minimum 11” x 17” size. If answering NO to any of the questions, plan check shall be required.
Project Address:
Contractor Company Name:
Contractor License Number:
YES NO Are the following applicable to the proposed project?
1. Will the PV system layout provide the required three-foot wide clear access pathways
per Section 605.11 of the California Fire Code, and is this shown on the roof plan?
2. Will the PV system be installed on a roof having only one roofing layer with no
overlays?
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

ELECTRONIC RECORD AND SIGNATURE DISCLOSURE
From time to time, California Solar & Electric, 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
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

electronically to you through the DocuSign system all required notices, disclosures,

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.
