No. Red Brick Solar will utilize either crystalline silicon solar modules or thin-film photovoltaic modules—both of which are nontoxic. Crystalline panels use a crystal lattice of silicon atoms to convert sunlight into electricity. Silicon is the second-most-abundant material on Earth (after oxygen), the most common semiconductor used in computer chips, and is nontoxic.
