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.

1. Solar Photovoltaic - Why It is Important

3. HOW A Solar Electric Systems WORKS

4. DEFINITION
of
BUILDING INTEGRATED PHOTOVOLTAIC (BIPV)
• Insulated PV glass unit

5. 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

7. COMPONENTS OF BIPV ELECTRIC SYSTEMS
 BIPV PANELS
 SOLAR INVERTERS
 SOLAR CABLES + CONNECTORS
 MOUNTING RACKS
 DISTRIBUTION PANEL

8. 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

9. 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

10. 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

12. 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

13. 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

15. 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

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