SOLAR ELECTRIC SYSTEM PROJECT - Project Size
VICINITY MAP: PROJECT SCOPE: DRAWING INDEX PERMITTING / PLANNING NOTES:
SOLAR ELECTRIC SYSTEM
THIS PROJECT ENTAILS THE INSTALLATION OF A
PHOTOVOLTAIC SYSTEM AT THE DENIER RESIDENCE. THE
SYSTEM WILL NOT BE A NET ELECTRICITY EXPORTER TO
THE UTILITY GRID.
THIS INSTALLATION CONSISTS OF A NEW ROOF MOUNTED
PHOTOVOLTAIC (PV)SYSTEM (SEE E101). THE PV SYSTEM
IS STATIC MOUNTED.
THIS SYSTEM WILL BE INTERCONNECTED TO AND WILL BE
OPERATED IN PARALLEL WITH THE SCE ELECTRIC GRID
PER THE REQUIREMENTS OF THE NATIONAL ELECTRICAL
CODE AND UTILITY INTERCONNECT AGREEMENT
CONDITIONS OF APPROVAL:
1. ALL CONSTRUCTION SHALL OCCUR BETWEEN THE
HOURS OF 7AM & 7PM, EXCEPT FOR THE PURPOSE OF
EMERGENCIES.
1. THIS PV SYSTEM INSTALLATION IS SUBJECT TO INSPECTION BY THE CITY BUILDING
OFFICIALS AND Your Company
2. THIS PROJECT SHALL CONFORM TO THE FOLLOWING CODE VERSIONS:
2013 CALIFORNIA BUILDING CODE (CBC 2013)
2013 CALIFORNIA ELECTRIC CODE (CEC 2013)
2013 CALIFORNIA FIRE CODE (CFC 2013)
USE ONLY APPROVED AND LISTED APPLIANCES, DEVICES, HARDWARE AND COPPER WIRE
FOR BRANCH CIRCUITS SUITABLE FOR INTENDED USE
