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!
