SCU 400^plus and SCU 800^plus Solar Silicon Melting and Crystallization Unit.

The system produces up to 400kg/800kg solar silicon ingots in a fully automatic cycle of less than 48/58 hours.

Several government programs support the shift towards renewable energy sources. In 2050 about half of the energy world wide is supposed to be produced from sources such as water, wind and solar power.

Sunlight is changed into electricity by means of photovoltaic cells. The raw material for these cells is silicon.

Market growth in production of solar grade silicon and solar modules is remarkable.

ALD contributes with metallurgical know-how to the cost-efficient and industrial production of solar grade silicon ingots which are processes into wafers, solar cells and modules.

The SCU400 is a stand-alone furnace for melting and crystallization of up to 400 kg solar silicon ingots in a fully automatic cycle.

ALD has many years of experience in this field and a large installed base with solar industry leaders.
