As shown in the cover photo, it is different from other products that integrate photovoltaic roofing with existing roofing. Solarglass replaces all existing roofing with materials that allow the roof to produce electricity. The roofing components are tested to standards specific to roofing, including fire, wind, rain, and impact resistance. Likewise, the PV and electrical components are tested to applicable standards, including fire, electrical, mechanical, and rapid shutdown. A complete list of certifications for each part may be found under System Certifications. Certificates of Compliance may be found at the end of this document. We would like to answer any questions you have. Please feel free to email codecompliance@tesla.com.

A: Each PV Module and Roofing Module is secured with traditional fasteners and recloseable fasteners. This attachment method has been evaluated to requirements in UL 1897,ASTM D3161 and UL 61730 (Mechanical). t Q: HOW MUCH DOES SOLARGLASS WEIGH? A: Solarglass's complete assembly weighs approximately 3.4 psf for textured tile. These figures include all elements above the roof sheathing, including underlayment and roof covering components. Q: WHAT IS THE MAXIMUM WIND SPEED THAT SOLARGLASS CAN WITHSTAND? Solarglass [Roof] is rated "Class F", the highest attainable wind rating under ASTM D 3161. Refer to IRC 2015 Section R905.16.7, IRC 2018 Section R905.16.6, IBC 2015 Section 1507.17.8, and/or IBC 2018 Section 1507.17.8; for applicability of wind ratings. Q: IS SOLARGLASS CERTIFIED CLASS "A" UNDER UL 790? A: Yes. The roof assembly (including the PV Modules, Roofing Modules, and underlayment) have been evaluated to the requirements of UL 790 and has a Class "A"fire rating when installed in accordance with the installation instructions. Q: CAN SOLARGLASS BE INSTALLED IN A HIGH FIRE HAZARD SEVERITY ZONE (HFHSZ) OR WILDLAND- URBAN INTERFACE (WUI)? A: Yes. Solarglass has a UL 790 Class Afire rating and complies with the applicable sections of IRC and IWUIC for installation in areas of elevated fire risk when installed according to the manufacturer's instructions using code-compliant flashings and accessory components. T = 5 L n 1561275-00-A SOLARGLASS I FREQUENTLY ASKED QUESTIONS 5 FREQUENTLY ASKED QUESTIONS,CONTINUED Q: DOES SOLARGLASS COMPLY WITH THE "COOL ROOF" RATING REQUIREMENTS OF CALIFORNIA TITLE 24? A: Yes. Solarglass complies with the 2016 CEC Building Energy Efficiency requirements of Section 150.2(b)1 I (a) (sometimes called the "cool roof' requirement)through its incorporation of an airspace between the roof deck and roof covering. Q: CAN YOU WALK ON SOLARGLASS? A: Yes. Solarglass is engineered to safely withstand applicable live loads required by the building code for steep slope applications. However, to ensure safety and maintain maximum roof life, walking should be avoided except by first responders and trained Solarglass installation professionals. This is a common recommendation for other high-end roof types, including slate, clay, concrete, and composite tile products. Q: HOW IS SOLARGLASS WIRED? IS IT DIFFERENT FROM TYPICAL PV INSTALLATIONS? A: Solarglass wiring is similar in most respects to traditional PV systems. It uses the same industry standard, UL-certified wire and PV connectors to combine modules in series strings. UL certified wiring harnesses, called Diode Harnesses, aggregate series-connected PV Modules. The combined circuits exit the roof via a listed assembly, called the Pass Through Box, to listed rapid shutdown devices. The strings then connect to a conventional DC-AC inverter. The wire routing and installation methods of the system have also been evaluated by UL. Q: HOW MUCH VOLTAGE AND CURRENT ARE PRODUCED BY A SOLARGLASS PV MODULE? A: One PV Module produces about 10.99 Volts and 5.32 Amps with a nominal power output of approximately 58 Watts. T = 5 L n 1561275-00-A SOLARGLASS FREQUENTLY ASKED QUESTIONS 6 FREQUENTLY ASKED QUESTIONS,CONTINUED Q: WHAT IS THE FUNCTION OF THE DIODE HARNESS? A: The Diode Harness is a UL listed, pre-manufactured cable assembly that connects PV Modules together in series and provides shading protection. In traditional solar panels, bypass diodes are housed in junction boxes on the back of each module. In Solarglass, the bypass diodes are in the Diode Harness. Under partially shaded conditions, the diode diverts current away from the shaded PV Modules. The diode also diverts current if a connector opens in the series. O Diode O Housing Diode MC4 Housing Connector J 1 , C i 1 MC4 Connector Q: WHAT IS THE MAXIMUM VOLTAGE AND CURRENT PRODUCED BY ANY SOLARGLASS CONDUCTOR? A: Maximum voltage and current on any conductor beneath Solarglass is less than 600 V and 10 A. T = 5 L n 1561275-00-A SOLARGLASS I FREQUENTLY ASKED QUESTIONS 7 FREQUENTLY ASKED QUESTIONS,CONTINUED Q: HOW ARE SOLARGLASS PV MODULES CONNECTED? A: Solarglass PV modules are connected in series using the Solarglass Diode Harness. The diode harness provides module-level shading protection with an individual bypass diode for each PV module. Diode harnesses are prefabricated for sub-strings of 1-4 modules. Multiple Diode Harnesses (with attached modules)are joined in series to create a larger string.

Diode Q: WHAT IS THE MAXIMUM NUMBER OF PV MODULES THAT CAN BE CONNECTED IN SERIES WITH DIODE HARNESSES? A: The maximum number of PV Modules connected in a single string is 39. TERM DEFINITION BYPASS DIODE Housed in the Diode Harness, a bypass diode protects a shaded branch of PV Modules by diverting current. DIODE HARNESS A UL listed, pre-manufactured cable assembly that connects strings of 1 to 4 PV Modules together in series using MC4 connectors. The Harness houses 1 bypass diode per module. PV MODULE A UL listed roofing and DC power-producing assembly of six high-efficiency, mono-crystalline cells with a nominal power rating of 24 Watts. ROOFING A UL listed roofing assembly that is aesthetically similar to the PV Module, but produces no power. MODULE T = 5 L n 1561275-00-A SOLARGLASS I FREQUENTLY ASKED QUESTIONS 8 FREQUENTLY ASKED QUESTIONS, CONTINUED Q: HOW IS THE SYSTEM GROUNDED? A: Unlike traditional PV modules and racking systems, Solarglass PV and Roofing Modules do not incorporate any accessible metal components. By eliminating accessible metal on the roof that might become energized in the event of a fault, Solarglass does not require connection to an Equipment Ground Conductor(EGC) until the array wiring exits the roof. Q: WHAT OTHER ELECTRICAL SAFETY FEATURES HAVE BEEN INCORPORATED INTO SOLARGLASS? A: Wire management features built into Solarglass support all wiring to protect it from anything that might cut or abrade its insulation. Because the system is enclosed, the wiring is protected from vermin and contact by people. Q: HOW DOES SOLARGLASS COMPLY WITH RAPID SHUTDOWN REQUIREMENTS? A: Solarglass meets 2014 and 2017 NEC Rapid Shutdown requirements by incorporating automatic disconnecting devices in the circuits leaving the arrays. Rapid shutdown is initiated by disconnecting the home from the utility, or by opening the PV system's main AC disconnect. The rapid shutdown components are certified to UL standards, including UL 1741. Q: DOES SOLARGLASS REQUIRE A SPECIAL INVERTER OR OTHER ELECTRONICS? A: No. Solarglass uses conventional DC-AC inverters. PV Modules are wired into series strings to achieve a target DC voltage below 600 V. No specialized electronics are required. Q: HOW DOES SOLARGLASS DEAL WITH ROOF OBSTRUCTIONS SUCH AS VENTS, SKYLIGHTS, DORMERS, VALLEYS, RIDGES, ETC.? A: Solarglass uses conventional flashing details and practices employed by all roofers to seamlessly integrate with ordinary roof obstructions. Solarglass uses a dedicated metal ridge cap. Q: IN AREAS SUBJECT TO "ICE DAMMING", WHAT UNDERLAYMENTS ARE USED? A: To prevent ice damming, Solarglass uses an underlayment that complies with ASTM D1970 and is approved nationwide as a self-adhering ice and water barrier. Q: WHO IS QUALIFIED TO INSTALL SOLARGLASS? A: Solarglass can only be installed by Tesla-trained technicians. Solarglass will not be distributed to, or installed by, conventional roofing contractors. Q: CAN SOLARGLASS BE ACCESSED FOR SERVICE? A: Yes. The Modules may be removed for servicing. No special tools are required.
