LEADING PERFORMANCE
IN LOW LIGHT
CONDITIONS.
Absorb more sunlight with our 3rd
generation solar tile. Designed without a
glass surface, our matte finish tiles
consistently provides more energy,
wherever the sun may be. Our low amp,
high voltage system produces energy
earlier in the day, and later into the night.

POWER MAXIMIZATION +
AESTHETICS.
Enter a new era of solar; cut-cell
technology lowers the power load per
cell, increasing efficiency. Furthermore, a
bypass diode prevents one shaded panel
from affecting others so you can achieve
maximum power on complex rooflines

CUSTOMIZE YOUR
SYSTEM.
Add battery storage add usage
monitoring to your system and stay
independent from the grid.

         becoming warped, bent, broken or otherwise damaged through normal use.

         Displacement of Parts: Every part of the appliance shall be designed to be secure against displacement
         and constructed to maintain a fixed relationship between essential parts under normal and reasonable
         conditions of handling and usage. Simulated logs and/or coal pieces are a functional part of the burner
         and shall be secured in position.

         Materials: Materials used in the construction of appliances shall have strength, durability, resistance to
         corrosion.

         Exposed Edges: Exposed edges, which may come in contact with the operator’s hand during normal
         adjustment, or usage should be smooth.

         Joints: Joints of surfaces enclosing combustion products shall not depend primarily on cement for
         tightness and shall be durable and rigid construction, such as welded, brazed, machined and bolted,
         tongue-and-groove, slip, lap, or screw joint.

         Threaded Parts: Bolts, nuts and screws employed in the assembly of the appliance shall not require the
         use of special tools for removal or replacement. Bolts, nuts, screws (except sheet-metal screws) and
         other threaded parts shall have threads conforming to the Standard for Unified Inch Screw Threads,
         ANSI/ASME B1.1 or the Standard for metric Screw Threads – M Profile, ANSI/ASME B1.13M.

         Controls: All controls and accessories including automatic gas ignition systems, piezo-electric spark
         devices, manual gas valves, automatic valves, gas appliance regulators, pilot gas filters and draft hoods
         must be certified.

         Internal Wirings: All primary, and grounding circuit conductors are CSA/UL certified TEW, TR-64, AWM
         SR-PVC or AWM XL-PVC, raged min 80°C, 300 VAC. All wiring is suitably routed and secured away from
         sharp edges and moving parts to prevent chafing of the insulation. Alternatively, additional insulation is
         provided where the wiring passes over sharp edges and through holes.

         Grounding: The green or green/yellow insulated grounding conductor of the power supply cord terminates
         singly in a crimp type, closed loop connector, secured to the chassis by a min. No. 6 plated or non-ferrous
         threaded screw, nut and star washer (to ensure surface coating penetration).

         Accessibility of Live Parts: All uninsulated live parts in primary circuitry are housed within a metal/plastic
         enclosure constructed such that any openings are not penetrable by the probe specified in the above-
         referenced Standard.

         Markings: The unit is to be marked with the manufacturer’s name or identifying symbol and address,
         model number, a distinctive number which will identify an individual appliance (serial number), electrical
         ratings, and cautionary markings where required. Products for end-use in Canada may be required to
                                                                     Page 7 of 34

         PRODUCT COVERED:

         Ergosun 15, a photovoltaic module with integral concrete roof tile. Application Class A and Safety Class II.
         Rated power output of 14.5 W 20-cell modules with a maximum system voltage of 600V; maximum fuse
         rating of 2.5 A; Class A roof covering material fire rating.

         PRODUCT DESCRIPTION:

         The ergosun 15 photovoltaic (PV) module with integral concrete roof tile converts power in the visible
         portion of the electromagnetic spectrum to DC electrical potential. The basic construction of the laminate
         consists of laminated assembly of individual solar cells and interconnecting ribbons encapsulated within
         an insulating material. This encapsulated assembly is pressed between a rigid transparent top surface,
         referred to as the Superstrate, and an insulating back surface, referred to as the substrate.

         The ergosun 15’s laminate is adhered to a rectangular concrete roof tile, with the PV cell area of
         approximately 300 mm by 345 mm. The max dimension of the laminate is 340 mm by 380 mm. Individual
         solar cell size of 25 mm by 152 mm; with minimum distance between cells of 3 mm. The dimensions of
         the concrete roof tile are 420 mm by 330 mm. The minimum dimension of the laminate is subject to the
         following distances: "Minimum distance between cell and the edge of the laminate [9 mm]" and "Minimum
         distance between any current carrying part and the edge of the laminate [9 mm]". The ergosun 15 has a
         PV module weight of approximately 0.65 kg and an area of approximately 0.14 square meters.
