Beyond the PanelLooking at PV in a Different Light
What Could the Future Look Like?

Our Mission
Architectural Solar Association (ASA) is an
industry advocate for standards development,
education, legislative regulations, building &
energy codes and solar architecture design
specification as they relate to integrating solar
into the architectural envelope.
We represent a growing industry with a
common goal of transforming building facades
and other architectural surfaces into generating assets.
•
Objectives
Standard Development
UL 1703 is a major barrier to integrating solar with the building
envelope. Changes in codes and standards are the first step
in widespread adoption.
Demand Creation
There is currently far too much uncertainty in the tax code and
how to establish effective financing mechanisms for
architectural solar installations. ASA looks to develop ways to
break down this uncertainty through various mechanisms.
Building Industry Adoption
The US building industry and the solar industry have yet to
fully integrate. Solar needs to be a ubiquitous resource to all
building professionals. ASA looks to make that possible.

BIPVPV with Architectural Significance
BIPV shall be defined as a photovoltaic
generating component which forms an
integral and essential part of a permanent
building structure without which a non-BIPV
building material or component would be
required to replace it. The performance of
power generation by a BIPV component is
deemed to be secondary to the role of being
a building material or structural component.
BIPV occupies a space in the building design
such that, if removed from that space, its
absence will be distinct and noticeable.
Why is the Market Ready for BIPV?
• Technology Advancements
• Steep $/W cost reductions
• Higher efficiency per unit area
• PV solar has reached grid parity
Compelling BIPV Economics• Competitive IGU COGS• Compelling payback• ITC credits & MACRS• Higher lease rates and velocity
Trending Tail Winds• Government BIPV Regulations • Net Zero Buildings• Green Building Incentives• Strong Desire for Sustainability

BIPVBenefits
• Increases distributed energy generation potential.
• Capable of serving multiple design intents.• Visually & Functionally
• Capable of reducing cooling load through shading.
• Manufacturing and installation costs can be analyzed on an incremental level.
Compelling Economics
• Ballpark Curtain Wall Construction “Price”
• $80-$120 per sq ft
• IGUs Price – $10-$15 per sqft
• PV Threshold for Tax Credit Parity
• $2.45 per watt PV @ 15% Efficiency = ~$34 per
sq ft
• BIPV Curtain Wall System @ 15% Efficiency
• $104 – $154 per sq ft
• Post 30% Federal Tax Credit Price
• $80-$108 per sq ft

So what could the future look like?
Architectural Solar holds the promise of being highly
suitable for the built environment. The variation in
products and integration possibilities could result in
aesthetically superior buildings with greater functionality.
From a technical perspective, the production process is
reduced in comparison to commodity solar solutions.
The savings in construction time and material together
with the improved aesthetics will contribute to the
success of BIPV.
The final and most important step will be to effectively
integrate solar solutions into the complete value chain of
the building industry.
