2. Presentation Overview  Solar Industry Overview  Intro into Solar Photovoltaics  Types of PV Systems  Solar Product Offering –Solar Combiner Boxes –Solar Pass Through Boxes –Solar Cord Grips

3. Solar Industry  Solar Industry Market –Expected to increase to $127B by 2016 –Driven by Renewable Energy acts –Federal and State funding –Rebates for extra energy consumption –Falling module and installation costs –ARRA certification The Solar Industry Is Big, Global & Growing! 3

4. Solar Photovoltaic Systems Off-GridGrid-Tie

5. Off-Grid Solar PV Systems  Off-Grid PV systems –Stand alone system –Battery back up –Low voltage electricity generation 12, 24, or 48V –Typically provide DC power to smaller systems (lights, signs, etc) –“I don’t want to run power from the line side”

6. Off-Grid Solar PV Systems

7. Grid-Tied Solar PV Systems  Grid-Tied (on-grid) PV systems –System that is connected to a large independent grid (typically public) and feeds power into that grid –The electricity demand is met by the system and the excess is fed directly to the grid –Inverter is required to convert DC electricity to AC –Used in high voltage electricity generation – 600- 1000V (buildings, residential rooftops, solar farms)

27. Solar Pass Through Boxes

28. Solar Pass Through Box  Used in residential applications  Provides low profile, cost effective solution  Transitions solar PV wire into traditional building wire  Designed for PV applications where over current protection is not necessary due to the low power rating of the PV string  Sometimes referred to as a “Transition Box”  Available in 3 and 4 circuit 28

29. Solar Pass Through Box 29 Factory installed 9 or 13 Multi hole CG allows for entry of multiple PV wires Skinned over glands offer flexibility to use from 1-13 available holes while still providing a liquid tight seal around the wire(s) Fiberglass (N4X) enclosure provided as standard offering long dependable service in the most environmental conditions Lightweight design offers easy mounting capabilities. Optional mounting feet are available for increased customer flexibility Rated 600VDC continuous duty Constructed in accordance with UL1741 standards providing spacious wiring room for quick easy wire termination

30. Solar Non- metallic Cord Grips

31. Solar Cord Grips  Used in residential applications  Multi-hole design allows for the entry of multiple PV wires coming into a combiner or pass through box  Provide mechanical strain relief as well as a liquid tight seal around the solar panel wires  Available in 1” (9 hole) and 1-1/4” (13 hole) 31

32. Solar Cord Grips 32 Multi-hole cord grip to allow for entry of multiple PV wires Solar cord grips offer customer flexibility by allowing the termination from 1 to 13 PV wires in a single connector Skinned over glands provide a durable, liquid tight seal around the wires No disassembly required!
