How FiT (Feed‐in Tariff) Works?
2 separate accounts with Power Utility Company:
• Electricity consumption bill: • Consumer pays for total kWh electricity consumed.
• FiT bill: • Power company pays to consumer for gross kWh electricity generated.
RM1.40/kWh

Other Benefits
Reduced Building Internal Heat Load •
•
•
PV Array provides shade to existing rooftop structure, equivalent to a double‐roof system
Significant Reduction of Rooftop temperature (from >70C to 35C)
Lower Internal Heat Load translates to power saving from Air Conditioning systems
