Are solar panels toxic?

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. Learn more at

Some communities have raised concern about thin-film photovoltaics, which can contain a compound called cadmium telluride (CdTe). However, these concerns have been shown to be unfounded. Cadmium telluride (CdTe) is a stable compound, and according to a 2019 study from Virginia Tech, CdTe photovoltaic installations pose little to no environmental health or safety risks (
