Apollo's bifacial solar modules can generate up to 35% more energy than traditional modules by capturing sunlight on both the front and back surfaces. The modules use advanced bifacial N-type silicon cell technology to achieve efficiencies up to 20.5% for power generation from both sides. Mounting the modules over reflective surfaces and in a way that minimizes back-side shading can maximize the energy gain from light reflected onto the back surface.

1. BIFACIAL MODULE
Apollo’s glass-on-glass modules make brilliant use of the sun by generating up to 35%
more energy per Watt than traditional modules.
Model B260/B250
High Module Efficiency
Module efficiencies of up to 20.5% are achieved
through the use of advanced bifacial N-type silicon cell
technology. Apollo’s unique cells offer equal front and
back efficiencies up to 19.6% helping customers capi-
talize on their solar investment.
Superior Low Light Performance
Apollo’s modules offer exceptional performance in
low light conditions.
Bifacial Technology
Both front and back surfaces of the module are equally
capable of generating electricity. The back surface
generates power through the use of light reflected from
the surrounding area. Mounting considerations that
maximize a site’s available albedo light can yield up to
35% gain in energy generation per installed Watt.
Seamless Integration
Apollo’s frameless modules with our streamlined j-box
offer a solution to many possible applications including:
Awnings, Canopies, Carports, Commercial Rooftops,
Dividers, Facades, Fencing & Siding.
Quality and Reliability
Advanced testing and inspection of every module
in-sures that quality is upheld. Apollo uses the latest
electroluminescence and class A sun simulator
technology in the testing of every module produced.
Proudly manufactured in the USA
and ARRA compliant
Apollo Solar guarantees the front and back side
power production for all its bifacial modules

IMPORTANT: Apollo modules are rated at STC conditions.These ratings do not account for additional
power produced from the back of the module. Under certain mounting conditions, Apollo modules could
produce up to 30% more power than their STC rating.This additional power should be accounted for when
sizing and selecting system components.
CAUTION: Read the Installation Manual and Design Guide carefully before using this product.

TO MAXIMIZE POWER
a) Avoid shading the back side of the module
by the support rack.
b) Mount modules over highly reflective surfaces,
such as a white roof or crushed white stone.
c) Elevate modules above the mounting surface
as much as possible.
