UK Predictions
• UK PV installations expected to increase ten-fold this year (up from 10 MW in 2009)
SolarBuzz UK PV Market Survey 2010
• “..up to 500 MW of yearly installations in 2014 under a Policy-Driven scenario.”

It is starting to happen on a small scale, but…

Effect of Feed-in Tariffs (FITs)
• No differentiation for BIPV
• Review April 2013
• France and Italy have BIPV premium FIT rate; lower rates for the more common installations
• More on FITs later..

Summarising drivers for BIPV
• Retrofit reaction (planners & public)
• Desire for green flagship buildings is increasing (e.g. Strata SE1)
• Cost of key PV components falling – cells, thin film
• Cost of grid electricity predicted to rise quickly, and supply is uncertain (affects all PV)
• FITs – adjustment to favour BIPV in 2013?

BIPV challenges - Education
Overcoming misunderstanding of capability and application of BIPV by:
• Educating public, planners & government before any reaction to retrofit affects whole market
• Demonstration of cost-effectiveness
• Demonstration good design & integration into buildings

Other BIPV challenges
• Clear route to certification for BIPV products• More BIPV for retrofit as well as newbuild• New building components required• Construction industry / PV workshop (BRE 2009)
highlighted these concerns:– Perceived system cost– Product lifetime - Warrantees– Aesthetic choices
• Making PV fit into our World, not vice versa
