SolarWorld Solar Systems is recalling 1.5 million solar panels installed with bare-copper grounding lugs, which can corrode, increasing the risk of electric shock, electrocution or fire.

The company has received one report of corrosion related to the bare copper lugs, but no injuries have been reported.

About 1.5 million systems were recalled in the U.S. and Canada.

Customers may be able to identify from the ground whether a tin-coated lug (silver) or a bare-copper lug (brown) has been used on their solar panels. Those who can identify the improper lugs should contact SolarWorld for replacement. If customers cannot determine which grounding lugs were used, they should contact SolarWorld to have an authorized agent inspect the installation and replace the lugs at no cost to consumers.

SolarWorld is also requesting that distributors and others remove SolarWorld's installation instructions dated before June 2014 from their websites or other commercial information sources.

This recall includes SolarWorld solar systems installed with bare-copper grounding lugs installed after June 1, 2010. The installation instructions for SolarWorld solar systems sold after June 1, 2010 called for the use of GBL-4DB lugs for grounding. SolarWorld has revised these installation instructions to explicitly call for tin-coated lugs, specifically Ilsco part number GBL-4DBT. "T" is for tin-coated and indicated by the silver color of the lug.

The systems were sold through SolarWorld installers and distributors, or other distribution companies from June 2011 to June 2014 for about $1,000 to $10,000 depending on the size.

Customers with questions can contact SolarWorld toll-free at (877) 360-1787.
