When slow cooling the silicon melt from it turns polycrystalline silicon, used for the manufacture of polycrystalline solar panels. Operation pulling silicon crystals from the melt is less labor intensive than the production of monocrystalline silicon, and therefore such solar cells cheaper. Still, a significant drawback of polycrystalline silicon is that it has a field with grain boundaries, which are slightly degrade its quality.

Panels a polycrystalline silicon have an efficiency somewhat lower than that of single-crystal panels. Guarantee the durability of these elements is approximately 10 years.  

According to the practice of the solar power plants in the field, you can talk on the life of polycrystalline modules - for over 20 years. Moreover, over the life of the power loss in the silicon polycrystalline cells is not more than 10%
