pped with DC connectors;
As a frameless laminate with a
high-volume junction box, with or
without 600mm leads with DC
connectors.
In Universal-framed and laminate
versions, the BP 850 is well-suited to
direct-coupled (batteryless) pumping
systems and to large utility-interactive
power systems.
Integra-Framed Modules
The BP 850 is available with BP Solars
patented Integra framing/ mounting/
wiring system, which facilitates quick,
low-cost installation on most support
structures and on sloped surfaces
such as roofs. These modules include
integral DC plug-together electrical
connectors which enable array electri-
cal connection without tools. Once
assembled, the connectors are
concealed in channels in the bronze-
anodized frame, providing smooth,
uncluttered appearance yet easy access
for trouble-shooting. For U.S. NEC-
compliant installation, additional
components are required, and are
available in the UL-listed installation kit.
Limited Warranties
Millennia photovoltaics are conserva-
tively rated, taking into account the
attenuation which occurs during the
first several months of deployment.
When first deployed, they generate
from 14% to 17% above their rated
power. They are covered by limited
warranties which warrant:
Power output for 20 years;
Freedom from defects in materials
and workmanship for 1 year.
See our website or your local
representative for full terms of
these warranties.
Quality and Safety
The following approvals and
certifications have been granted or
are pending for the BP 850, with the
exceptions noted.
Recognition (for laminates) or
Listing (for modules) by Underwriters
Laboratories for electrical and fire
safety (Class B fire rating);
Certification by TÜV Rheinland as
Class II equipment;
Approval by Factory Mutual
Research* for application in NEC
Class 1, Division 2, Groups A, B, C
& D hazardous locations;
Compliance with the requirements
of IEC 61646.
*Except for Integra-framed products and
products with output cables
Thin Film Photovoltaic Modules
BP 850
BP Solars Millennia modules are the most cost-effective photovoltaic
option for any application where mounting space is not a constraint.
While generating the most power for the lowest cost for large areas such
as roofs, they provide superb esthetics to blend with modern architec-
ture. With our patented Integra framing system, the BP 850 is
particularly well-suited for residential and commercial roofs; its inter-
locking frames enable fast installation and a seamless array appearance.
Heat-strengthened glass provides improved impact resistance.
BP Solar is an established leader in thin film technology. The Millennia
process creates solar cells by depositing thin layers of semiconductor
alloys on glass, then forming individual cells by a patented laser-scribing
process. Millennia modules enhance efficiency by stacking two silicon
solar cells vertically, with each cell tuned for optimum conversion of
different segments of the spectrum.

BP 850 Proven Materials and Products
These products reflect BP Solars three decades of PV system experience
and hundreds of thousands of deployed Millennia products. Their impact
resistance is now enhanced by the use of heat-strengthened glass. The
modules active area is enclosed by two 3mm sheets of this tough glass,
with EVA (ethylene vinyl acetate) providing a weatherproof seal.

Notes
1. These data represent the performance of typical modules as
measured at the module output, and do not include the effect of
such additional equipment as diodes. The data are based on meas-
urements made in accordance with ASTM E1036 corrected to SRC
(Standard Reporting Conditions, also known as STC or Standard
Test Conditions), which are:
illumination of 1 kW/m
2
(1 sun) at spectral distribution of AM 1.5
(ASTM E892 global spectral irradiance);
cell temperature of 25°C.
2. The power of Millennia modules varies in the normal course of
production; the rating of this product reflects that variance.
3. Stabilized value.
4. For maximum system voltage design calculations.
