Best-in-Class Solar Modules
MEMC offers a range of solar modules designed for commercial, residential, small business and
utility installations. With world-class manufacturing, best practices, and business agility, MEMC
proactively partners with local manufacturers to develop solutions tailored to meet customer
requirements for specific applications and markets.
Utility and commercial customers will experience a rapid return on their investment with our high power,
large-format solar modules. MEMC continually strives to increase module power output, which in turn
provides a reduced Levelized Cost of Energy (LCOE) and keeps balance of system (BOS) costs to a
minimum. Advanced manufacturing processes and rigorous quality control at each step provide peace of
mind, enabling customers to deploy even large-scale solar solutions with complete confidence.
For residential customers, MEMC offers cost-effective solar modules that are developed specifically for the
distinct needs of homeowners and small businesses. Based on innovative MEMC technology, they provide
a system that is highly efficient yet aesthetically appealing. Our residential solar modules feature a small form
factor and deliver high power output to minimize system size and footprint. Simple and easy to set up, this
convenient solution is designed to reduce complexity and to speed installation time.

Budgets are always a concern for small companies and homeowners, so MEMC leverages our integrated
manufacturing process and years of expertise to provide a competitively-priced solution. We manufacture
and control our own supply of polysilicon, wafers, and cell products, which in turn enables pricing that is not
impacted by external spot markets. The result is maximum value for our customers and a rapid return on
investment.

Module Durability and Reliability
Our strategic partnership with a world-class Electronic Manufacturing Services (EMS) company
allows us to manufacture high-quality solar modules and provides us access to their extensive
network of manufacturing and logistics facilities. This relationship delivers greater scalability,
reduced time to market, and lowers customer costs.
Designed with Proven Components
MEMC solar modules are constructed utilizing robust, proven components that are designed to maximize
lifespan and deliver superior efficiency.
Our modules feature industry-leading Solaicx CCz mono-crystalline cells developed for maximum efficiency
and performance. We utilize low-iron ARC glass, featuring a stippled inside surface. This rugged glass helps
eliminate cell cracking while maximizing energy production by enabling maximum sunlight transmission.
MEMC solar modules utilize ethylene-vinyl acetate (EVA) and back-sheet material that is fully compatible
with our glass to ensure excellent adhesion and durability. High ductile and conductive cell interconnection
ribbons enhance thermal cycle efficiency.
For environmental protection, MEMC utilizes a well-designed junction box and diodes that are crucial to
maintaining a sealed interface with the outside environment. Our solar module components feature an
advanced frame design that can withstand wind forces and, in some cases, snow loads.
Backed by 25-year Warranty
Our solar modules are backed by the financial strength of a company that has been a leader in the
semiconductor industry for more than 50 years, and are safeguarded by a 25-year warranty to help
ensure Levelized Cost of Energy (LCOE).

Innovation is at the heart of MEMC’s culture, enabling us to
create new products, new manufacturing methods, and new
processes. Our strength lies not only in producing best-in-class
products, but in forging mutually beneficial relationships with
our customers. We continually strive to maximize efficiency
and drive down LCOE and BOS costs. The result is consistently
superior value for our customers.

Groundbreaking Polysilicon Processes
Polysilicon is the raw material at the heart of solar components, and demands exceptional quality,
consistency, and purity. To meet these requirements, MEMC produces its own electronic-grade polysilicon
using a fully-integrated front-end manufacturing strategy with strict quality control across each step of the
process. The result is a consistent supply of exceptionally pure polysilicon that can be blend-tailored to meet
specific customer requirements — delivering the highest value and driving to grid parity.
Advanced Wafer Manufacturing
Using a unique, proprietary CCz crystal process, MEMC manufactures exceptionally high-quality ingots for
conversion into silicon wafers. Solaicx CCz solar wafers maximize efficiency through improved electrical
performance. Using Solaicx mono-crystalline wafers enables solar cell manufacturers to create higher
efficiency cells at competitive costs — ultimately reducing the LCOE for the end-user. Our advanced
manufacturing processes help ensure quality and consistency from wafer to wafer for superior solar
solutions.
Advanced Solar Cell Development
MEMC has established strategic partnerships with industry leaders worldwide to develop and manufacture
solar cells. Our relentless efforts to innovate at every step of the value chain — from manufacturing highquality
ingots, to proprietary Solaicx mono-crystalline wafers, to developing leading-edge cells — drives
our cost-effective, high-efficiency solar cell manufacturing solution. The MEMC proprietary cell platform
combines the unique materials properties of our Solaicx mono wafers with leading cell technologies in the
industry, which in turn enhances efficiency and reduces the project BOS cost per watt.
