Solarisation of PAPRDSG
Dream starts in Jan 2014 Actualisation in Nov 2015
Solar PV – Evaluation (1)
Our Bedok Factory has over
20,000m2 of unobstructed roof
space. To calculate the solar
generation capacity.
Roof Space
Large areas of roof space on 7 buildings
100% Electricity supply from SP power grid
Electrical Supply
1) Electrical Consumption
pattern. Can all Solar energy
generated be consume?
2) Electrical Drawing. Where to
tap the incoming Solar
supply to?
Comercial Issue
1) Land leasing Agreement
2) Electricity Procurement
Agreement
3) Solar Leasing Contact
negotiation ( legal )
Solar PV – Evaluation ( 2 )
Concrete roof
Roof Type
1) Type of Roof
2) Maximum Roof load
3) Roof access
4) Roof condition
5) Existing accessories on roof (exhaust, skylight, turbine ventilator)

Challenges faced:-
1) Very long Solar Leasing Contract period
2) Unforeseen Corporate Business strategies within the contract period
3) Schedule for Solar Electrical Termination
4) Obstruction on Cabling works
5) Suitable location of invertors
Solar Energy System Overview
Power generation: 310,000 kwh/mth
2.86 MWp Electricity Generation
Total No. of Solar panels : 11,916 pcs Installed on 7 building roofs
HIT Solar Panels
Inverters
Electrical Panels
WHY WE CHOOSE HIT PANELS
1) 25.6% world’s highest level cell efficiency (R&D level). High level of efficiency

Panasonic Quality Testing Program
First grid-connected residential solar system in Japan still in full
operation without any troubles after 24 years (Not heterojunction type)
No outstanding output loss for 12 years of operation Residential solar system installed in UK in 2004, operating without any outstanding
degradation for 12 years. The system assures the customer satisfactory power generation.

Benefits of Utilisation of Solar Energy
Electricity supply from Power Grid
7% Electricity supply from Solar Energy
Cheaper Solar Electricity Annual Electricity cost saving of $18,600
Contracted Capacity (CC) Charges Reduction
Annual CC Charges cost saving of $155,000
Carbon Emission Reduction Projected to save 1, 960 Ton/yr
A Brighter, Cleaner & Cost Saving. A way forward
Benefits of Solar Leasing
1) This project is a zero investment project. The project cost is fully funded by the solar
company. ( Solar Leasing scheme )
2) Enlarge CSR program for students factory visit and study green energy generation.
