1.5	QUALITY ASSURANCE
A.	Manufacturer Qualifications: Company specializing in manufacturing products specified in this section with a minimum of five years documented experience.
B.	Installer Qualifications: Company specializing in performing Work of this section with minimum two years documented experience with projects of similar scope and complexity.
C.	Source Limitations: Provide each type of product from a single manufacturing source to ensure uniformity.
D.	Mock-Up: Construct a mock-up using a window from the IGU manufacturer with actual materials in sufficient time for Architect's review and to not delay the construction progress. Locate mock-up as acceptable to Architect and provide temporary foundations and support if necessary. Coordinate with the appropriate Division 8, glazing specification.
1.	The intent of a mock-up is to demonstrate quality of workmanship and visual appearance.
2.	If the mock-up is not acceptable, rebuild the mock-up until satisfactory results are achieved.
3.	Retain mock-up during construction as a standard for comparison with completed work. 
4.	Do not alter or remove mock-up until work is completed or removal is authorized.
1.6	PRE-INSTALLATION CONFERENCE
A.	Convene a conference approximately two weeks before scheduled commencement of the Work. Attendees shall include Architect, Contractor and trades involved. Agenda shall include schedule, responsibilities, critical path items and approvals.
1.7	DELIVERY, STORAGE, AND HANDLING
A.	Store and handle in strict compliance with manufacturer's written instructions and recommendations.
B.	Protect from damage due to weather, excessive temperature, and construction operations.
1.8	PROJECT CONDITIONS
A.	Maintain environmental conditions (temperature, humidity, and ventilation) within limits recommended by manufacturer for optimum results. Do not install products under environmental conditions outside manufacturer's recommended limits.
1.9	WARRANTY
A.	Manufacturer's standard limited warranty unless indicated otherwise.
PART 2    PRODUCTS
2.1	MANUFACTURERS
A.	Acceptable Manufacturer: Stellaris Corporation, which is located at:<BR />30 Technology Way, Suite 1W3<BR />Nashua, NH 03060<BR />Email: request info (info@clearpower.energy);Web: https://www.clearpower.energy 
B.	Substitutions: Not permitted.

2.2	PHOTOVOLTAIC INSERT FOR INSULATING GLASS WINDOW UNITS (IGU)
A.	Basis of Design: ClearPower Photovoltaic Cell Lattice Window Insert as manufactured by the Stellaris Corporation. A simple vertical, self-supporting array of narrow proven, high-efficiency bi-facial horizontal crystalline silicon solar cells and interconnecting conductor supports, inserted between lites of an insulated glass window. The array produces power comparable to a high-efficiency opaque solar panel yet maintains views and transparency.
1.	An ' extra-low voltage device' not requiring electrical certification.
2.	Lowers air conditioning loads by controlling solar heat gain
3.	Easily adapts to any size IGU.
4.	Electrical Performance: Determined as tested by The National Renewable Energy Laboratory (NREL)
a.	Open-Circuit Voltage (Voc): 36 volts maximum per unit. 
b.	Low Voltage Output: Designed to interface with industry-standard solar micro-inverters.
c.	Output Power: Dependent on window size, geographical location, and solar irradiance, but approaches the output of high-efficiency, non-transparent solar modules with the same orientation.
d.	Lattices: Electrically connected in parallel.
5.	Window PV Inserts:
a.	Array: Comprised of 60-cell lattices.
1)	Dimensions (Width x Height x Depth): 6-1/8 x 15-3/8 x 5/16 inches (156 x 390 x 8 mm).
b.	Spacer Frame: With ports for addition of desiccant when assembled by the window fabricator.
c.	No maximum window size. Margins not filled by electrically active lattices can be filled with electrically in-active cell lattices.
d.	Insulated electrical power leads routed up inside surfaces of spacers, exiting spacer frame through insulated grommets.
e.	Positive and negative leads longer than window sealant, allowing routing through window frame and building
B.	Insulated Glass Window Units: Supplied by others.
1.	Low-E Coatings: Preferable on Surface 3 to optimize photovoltaic power output.
2.	Spacing Between Lites: Minimum: 7/16 inches. Maximum: None.
a.	To be Argon-filled assuring long-term performance of solar cells.
3.	Pre-applied micro adhesion dots for subsequent activation and adhesion by the window fabricator to Surface 2 of an IGU.
PART 3    EXECUTION
3.1	EXAMINATION
A.	Do not begin installation until the substrates have been properly constructed and prepared.
B.	If substrate preparation is the responsibility of another installer, notify Architect in writing of unsatisfactory preparation before proceeding.
3.2	PREPARATION
A.	Clean surfaces thoroughly prior to installation.
B.	Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
