Science Park Building-integrated PV Installations, 198 kW
HK PV Potential
Barriers to PV (residential) Category Barrier Category Barrier
Technical and environmental
• Limited space • Roof orientation • Building cannot support
PV • Immature technologies • Short product lifespan • Reliability • Safety issues • Low output
Market • Lack of information • Installation difficulties • Maintenance difficulties • Lack of technical support • Landlord can increase rents • Uncertainty over duration of
leases • Accessibility of products
Economic and financial
• Long payback period
• High upfront cost
• High maintenance cost
• Low cost-effectiveness
• Uncertainty over cost
Policy and regulatory
• Ambiguous regulations: is it legal?
• Insufficient policy support
HK Solar Map • An informational
tool for potential PV adopters.
• A marketing tool for the PV industry.
• An advocate tool for PV policy.
Policy scenarios show how supportive policies can significantly reduce payback period.
Future work: Connecting
solar installers and
customers
Future work: Education on
the forthcoming feed-in tariff
Thank you very much!
