FLAT ROOFING Flat to low slope  Commercial and Industrial Types of Flat Roof Materials and Their Differences  BUR – Built Up Roofing  Modified – Modified Bitumen  EPDM – Ethylene Propylene Diene Monomer  TPO - Thermoplastic Polyolefin  PVC – Polyvinyl Chloride  Others – Hybrids, Metal etc

Multiple plies of:  Saturated felts, coated felts, fabrics, or mats assembled in place with alternate layers of bitumen, and surfaced with rock, coating, or cap sheet. BUILT UP ROOFING “Old School” – Tar and Gravel

BUILT UP ROOFING Advantages:  Tough  “Name” recognition  Length of time on market Disadvantages:  Not energy efficient  Cost  Equipment / Experience  Manufactured from the residues of the asphalt and petroleum industries  Disruptive installation – (Hot Tar/Odor)  If installed correctly very expensive (tear-off, tapered) Warranties from 5-25 years depending on manufacturer and application

MODIFIED BITUMEN A bitumen modified by including one or more polymers (e.g., atactic polypropylene, styrene butadiene styrene, etc.) Composite sheets consisting of a polymer modified bitumen often reinforced with various types of mats or films and sometimes surfaced with films, foils or mineral granules.

Advantages:  Tough, Market penetration / availability and Materials Cost Disadvantages:  Typically not energy efficient, Installation methods and Long term costs  Manufactured from the residues of the asphalt and petroleum industries  Dangerous / Disruptive installation (odor, open flame)  If installed correctly very expensive (tear-off, tapered) Warranties from 5-25 years depending on manufacturer and application MODIFIED BITUMEN

EPDM (Rubber) ETHYLENE PROPYLENE DIENE MONOMER Manufactured from the residues of the rubber industry (Firestone) Ballasted applications popular....tape seams If installed correctly very expensive (tear-off, tapered) Warranties from 5-25 years depending on manufacturer and application Advantages:  Flexible/ Market penetration / availability/Materials & Install Cost Disadvantages:  Typically not energy efficient/ Adhesion to self/ Long term costs/ Fire

EPDM (Rubber) ETHYLENE PROPYLENE DIENE MONOMER

TPO THERMOPLASTIC POLYOLEFIN A blend of polypropylene and ethylene-propylene polymers. Colorant, flame retardants, UV absorbers and other proprietary substances may be blended with the TPO to achieve the desired physical properties. May or may not be reinforced. Environmentally Friendlier

PVC POLYVINYL CHLORIDE A synthetic thermoplastic Polymer prepared from vinylchloride. PVC can be compounded into flexible and rigid forms through the use of plasticizers, stabilizers, fillers and other modifiers. Rigid forms are used in pipes; Flexible forms are used in the manufacture of sheeting and roof membrane materials.

PVC POLYVINYL CHLORIDE Advantages:  Flexible Energy, Efficient, Heat Welded, Materials & Install Cost Disadvantages:  Past Failures (Early 80’s)  Thinner Membranes (40mil)  Materials Costs  PVC Roofing Material is not a by-product of another industry  Ease of installation and repair  Extremely minimal maintenance required Warranties from 5-25 years depending on manufacturer and application

PVC INSTALLATION METHODS Mechanically Fastened  Attach roof using screws and plates  Most popular method of PVC attachment  Recommended when using PV Solar

PVC INSTALLATION METHODS Fully Adhered  Roof is 'glued' down

PVC INSTALLATION METHODS

 Heat welded using a powerful hot-air blower (400 F)  Seams are the strongest part of the PVC roof  No chemicals, glues, or adhesives PVC WELDING PVC

Various materials including 5” Polyisocyanurate insulation, Fanfold insulation with 6mil Polyethelene film vapor barrier PVC INSULATION & SLIPSHEETS Serve Multiple Purposes:  Add ‘R’ value to the facility  Provide separation between PVC and old roofing  Provide positive drainage (tapered)

Dr. Heshmat Laaly World Renowned Expert in Traditional Roofing Materials and Photovoltaics Patent for Photovoltaics in combination with Single Ply Roofing Membranes Author of “The Science and Technology of Traditional and Modern Roofing Systems” AN EXCITING NEW SOLAR ROOF APPLICATION

SOLARSAVE ® THE EVOLUTION OF PV DESIGN THE EVOLUTION OF ROOFING The Worlds largest, lightest and most powerful crystalline solar module

SILICON SOLAR CELL TECHNOLOGIES Thin film (Amorphous Silicon)  Lowest power output ~ 5-7% efficiency Polycrystalline  Mid level power output ~ 12-15% efficiency Monocrystalline  High level power output ~ 16-18% efficiency SolarSave™ … SunPower Monocrystalline  Premium level power output > 20%  Highest available in the industry today

SOLARSAVE ® - PREMIERE SERIES “Everyone wants new technology but they want it to be 25 years old” Heat and pressure sealed multi-layer laminated construction SP 450: 48” x 96” x ¼” module, 450 Watts SP 225: 48” x 50” x ¼” module, 225 Watts  Electrical compatibility with SP-450 module Integrated with PVC single-ply roofing membrane  Used as roofing material for 50 years  20 year material warranty Industry leading energy output  Up to 15 watts/ft² Lightweight  Less than 2 lb/ft² 20 Year performance warranty

SOLARSAVE ® - PREMIERE SERIES Module Construction – Performance and Durability Enhanced flouropolymer top coat  Diffuses heat  Captures low levels of light … 2-5% better than glass  Low surface tension … repels dirt and water better than glass Maximizes power output in shade … embedded bypass diodes Low Cost Installation - Conduit ready MC junction box with plug- and-play leads UL1703 Listed, CEC Listed Class A fire rating SP-450SP monocrystalline cells - 2 parallel strings of 80 cells connected in series 80 monocrystalline cells - 1 string of 80 cells connected in series

Key Challenges  Roof penetrations (rack-mounted systems)  Structural weight implications (ballasted systems)  Wind uplift problems  Requires waterproof substructure  Creates water ponding … Roof remains damp/wet under modules – plant growth, mold and mildew  Penetrations cause roof warranty invalidation TRADITIONAL APPLICATIONS RACK-MOUNTED AND BALLASTED

TRADITIONAL APPLICATIONS THIN FILM TECHNOLOGY Key Challenges  Very low power output ~ 5-7 % efficiency, 4 watts per ft² Requires vast roof area to generate required electricity  Individual modules are very large Unable to be installed around roof objects

SolarSave ® is the roof …  Waterproof … No roof penetrations No leakage risks Doesn’t void roof warranty  Lightweight … Less than 2 lbs. ft² No structural reinforcement required No water ponding Roof stays dry, free from rot, mold and plant growth  Building integrated … No wind uplift issues Highest energy output in the industry  Up to 15 watts per ft² Eliminates traditional challenges for solar on new construction as well SOLARSAVE ® - THE SOLAR EVOLUTION SOLVES ALL THE PROBLEMS WITH TRADITIONAL SYSTEMS

INSTALLATION Standard Single-Ply Roofing Methods  Mechanically Fastened  Fully Adhered Multiple PVC membranes supported  TPO planned in future Recommended method  Install PVC membrane roof per standard practice  Heat-weld SolarSave TM Membrane modules to roof

INSTALLATION

SOLARSAVE ® - INSTALLATION ADVANTAGES EASY AND INEXPENSIVE TO INSTALL No rack mounting hardware or heavy ballast required  Lower installation labor and material costs Module sizes allow for installation around roof objects  Maximizes solar electricity output Can be installed over existing roof  No demolition and disposal costs Fully expandable
