US Tensile Beginnings PTFE Fiberglass and NASA (1969)
First commercial projects (1972) Lightweight long‐span roofs (1975)
Basics
Conven&onal structures:
– Dependent on gravity and rigidity – Walls and framing working in compression
Tensile structures:
– An>‐clas>c (bi‐axial) forms – Membrane and cables working in tension
Thus, the fi5h building material:
– Wood, stone, metal, glass, and . . . membrane

Benefits of 3rd genera>on Solar Technology (OPV)
Versus
Tradi>onal Solar Panels
• Requires a huge amount of energy input
• Toxic gases and hazardous chemicals such as arsenic, cadmium, and titanium
• Larger carbon footprint; high disposal costs
Environmentally
• Panels use the lowest carbon footprint of all solar panels and they are biodegradable
• Pose no threat to the environment
Traditional PV (OPV)
• Expensive due to the high production costs and the high price of silicon.
• Extremely heavy
• Roofing systems require reinforcing to carry the extra load
Economically
• Roll-to-roll manufacturing process
• Much lighter
• Eliminates extra load requirements
Traditional PV (OPV)
• Can never be more efficient than the first day of installation
• Degrade at the rate of 1% (approx.) per year
Efficiency
• OPV panels bonded to membrane
• Simple replacement when energy demands increase
• May be used effectively indoors and outdoors
Traditional PV (OPV)
FAQs
How efficient are OPV panels?
Currently, OPV panels have ~7% efficiency, with the theore>cal limit in the region of 50‐60%
Since OPV panels generate energy from any light, they generate electricity from daybreak to sunset
Conven>onal PV is most effec>ve only from 10am‐3pm and with no cloud cover
FAQs What is the project life-span of the ‘bonding system’ which houses the Power Plastic?
High-grade ETFE membrane
Carries a 15-year warranty
What is the current useful life for Power Plastic?
The current life of our panels is 3 to 5 years
Over the past 3 years, no degradation identified
FAQs What are the compara>ve costs between conven>onal PV and Power Plas>c?
OPV u>lizes only dyes & chemicals on a plas>c plauorm (vs. high cost tradi>onal PV)
OPV prin>ng press manufacturing process is simpler and more cost effec>ve
Conven>onal panels repaid over 15‐17 years (based on local electricity costs)
Power Plas>c expected to have 4‐5 year payback period
