The picture is just a representation of color actual item size is listed below.  

The 0.51V  3.82W Commercial Solar Cell is ideal for home and commercial solar applications and solar panel construction of any size. Each Commercial Solar Cell features ultra-high efficiency great durability and is laser-cut to exacting specifications for precision quality control and guaranteed performance.

Item is a thin wafer Very Fragile as a result is not returnable.

Silicon Solar provides some of the highest grade Mono-Crystalline solar cells that are available on the consumer market. These cells are cut with laser precision accuracy that guarantees the same cell size from one to the next. Silicon Solar sells these cells in small or large quantities making them an affordable and quality choice for DIY’ers alike. An excellent choice for solar panel customization.

Photovoltaic devices use semiconducting materials to convert sunlight directly into electricity. Solar radiation which is nearly constant outside the Earth’s atmosphere varies with changing atmospheric conditions (clouds and dust) and the changing position of the Earth relative to the sun. Nevertheless, almost all U.S. regions have useful solar resources that can be accessed.
