Turnkey line offerECM offers turnkey solutions for PV manufacturing units (Wafer, cell, module). The first wafer line of 70MW has been sold to Kazakhstan with a commissioning planned for early 2013. The line is evolutive towards the following technologies: Capacity increase G6 800Kg, Mono-like (CrystalMax), increase capacity to 100MW
ECM partners with key suppliers to propose a differentiating offer to its customer.

A superior technology with continuous improvement
Mono-like technologyAdvantages
ECM , in partnership with CEA-INES has developed since 3 years a superior technology for silicon crystal growth: Mono-like (Branded Crystalmax in ECM)
Up to now there were only 2 traditional technology for crystalline silicon growth: MULTI and MONO, mono-like brings the best of both worlds:
MULTI MONO
MONO-LIKE
Cheap Low efficiency Expensive High efficiency
Cheap High efficiency
Mono-like is cheaper than MONO
Mono-like has a higher efficiency than MULTI
Mono-likeMarket trend
Cost competitiveness Technology market share
Mono-like is cheaper
than mono and more
efficient than multi
Its cost per watt is in
between mono and
multi at the moment
Mono-like is expected
to grow at the expense
of classic mono process
Pure mono N-type is
expected to grow
threefold by 2020
Mono-like N-type is
unforeseen by analysts
