DESCRIPTION
Building Integrated Photo Voltaic (BIPV) for multi-storied commercial buildings- how to perform QA/QC of the project has been described briefly in the slides.
Citation preview
Solar Photovoltaic - Why It is Important
Renewable, sustainable form of energy
Harmful effects on environment- ZERO
Provide energy independence.
Most abundant energy source available.
Reduces the financial cost of electricity.
Reduces Carbon Emission caused by the
large thermal (coal-based) power plants.
1. Generation of DC Power from SPV
2. Transmission of String’s power to
Array Box
3. Array box to combine all the PV
strings
4. Power conversion from DC to AC
5. Feeding Power to Load
Distribution Panel
6. Wi-fi connectivity to remotely
monitor the system
HOW A Solar Electric Systems WORKS
DEFINITION of
BUILDING INTEGRATED PHOTOVOLTAIC (BIPV)
• Insulated PV glass unit
WHY BIPV?
• LOWER COST
• IMPROVED ASTHETICS
• WIDER DISTRIBUTION
APPLICATION OF BIPV
• ROOFINGS
• SKYLIGHTS-CANOPIES
• CURTAIN WALLS- VERTICAL GLASS
• c-Si PV CELL COLORS
• DIFFERENT TYPES OF BIPV APPLICATIONS
COMPONENTS OF BIPV ELECTRIC SYSTEMS
BIPV PANELS
SOLAR INVERTERS
SOLAR CABLES + CONNECTORS
MOUNTING RACKS
DISTRIBUTION PANEL
DESIGN CONSIDERATIONS
ROOF AREA AVAILABLE VISION GLASS APPLICATION
SPANDREL AREA INSTALLATION
TYPE OF PV CELLS & PANELS (SIZE, COLOR & SPACING)
TYPE & SPECIFICATION OF PCU (POWER CONDITIONING UNIT)
CABLES & CONNECTORS TYPE
ORIENTATION & ELEVATION
ANTICIPATED ENERGY PRODUCTION
CURTAIN WALL CONSIDERATIONS
ACCOMMODATE GLASS WITH END CONNECTORS
INCORPORATE WIRES & JUNCTION BOXES
COMPLY WITH BUILDNG CODES, IEC, IS & UL
GASKET & SEALANT COMPATIBILITY
AIR, WATER & THERMAL PERFORMANCE
ALLOW FOR FUTURE ACCESS TO WIRING
QUALITY CHECKING & DESIGN CONSIDERATION OF BIPV CELLS & PANELS
Pv Cell Technology Has To Be Of 3rd Generation Based
Cell Efficiency Has To Be Greater Than 17%
Module Efficiency Must Be Greater Than 14%
NOCT Should Lie Between 56 to 62 C
Power Temperature Co-efficient Not More Than -0.47%/ C
At Irradiation 600w/sq.m/Day And At 25 C , Module’s Output Need To Be 55% Or More
Of It’s Rated Peak Power.
BIPV Modules Must Comply With IEC-61215 & IEC-61646

DESIGN CONSIDERATION FOR SOLAR INVERTERS
Micro Or String Type Inverters Can Be Used In Such Applications
Must Have 1 MPPT Per Inverter
Conversion Efficiency Has To Be Greater Than 95%
Should Operate At Unity P.F
Total Harmonic Distortion Should Be Less Than 2%
Must Comply With Anti-islanding Protection
Self Consumption Should Be Less Than 2%
Transformer less Topology Is Preferable
Grounding Arrangement Has To Be Included
Must Have A Surge Protection Device
Product Warranty Should Be At least 15 Years
Remote Monitoring & Data Acquisition Facility Is Preferable
Inverter Must Comply With UL-1741/ IEEE-1547
DESIGN CONSIDERATION FOR SOLAR CABLES
MUST WITHSTAND 120 C TEMPERATURE
RATED VOLTAGE HAS TO BE 0.9/1.8 KV DC
INSULATING MATERIAL SHOULD BE HALOGEN FREE CROSS-LINKED COMPUND
PRODUCT MUST COMPLY WITH IS-8130

PV ARRAY TILT & ORIENTATION
TILT TILT DEPENDS ON THE
LOCATION LATITUDES e.g FOR DELHI, THE TILT
ANGLE WILL BE 28 (FIXED) WHERE AS FOR KOLKATA IT’LL BE 23
INSTALLATION OF BIPV SHOULD BE DONE IN A WAY TO OPTIMIZE THE TILT ANGLE

0
ORIENTATION DEPENDS ON THE LOCATION’S
AZIMUTH FOR INSTANCE, A SPV SYSTEM
AT DELHI SHOULD BE FACING DIRECTLY TO SOUTH
