Commercial Solar Cells

The 0.51V  4W 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.

Don't forget the accessories you'll need

Be sure to check out our soldering iron and accessories perfect for building your solar panel project.
  • Soldering Iron – make sure you have a good quality soldering iron when soldering solar cells.
  • Flux Pen – Is essential when building a solar panel. Not all flux pens are created equal. Make sure the flux will not react with your solar cells after 1-2 years (80% of flux on market will destroy solar cell)
  • Tabbing – You’ll need 2mm and 5mm tabbing. The 2mm is for interconnecting between the solar cells, and 5mm between your “strings” of solar cells.

Plan a little before building your solar panels.

  • How many watts do you need? 
  • What voltage do you need?
  • Where will the solar panel go? 
  • How will you encapsulate it?
