rooftop pool solar panel leaks?

We Answered:

Depending on the material and operating temperature of the panel, it MAY be possible to fix it very simply and easily by applying Hot Glue Gun adhesive over the cracked area. The high temperature glue gun adhesive melts at approximately 160 degrees Farenheit, and if the collector temperature does not quite reach, or exceed that operating temperature, then that repair method should work.

Another possibility is an aerosol spray can product called "LeakEnder." This is usually available at your local hardware store, or the major home improvement centers [like Lowe's, Sutherland's, Home Depot, McCoy's, etc.]. After preparing the area to be patched by cleaning, you just spray the LeakEnder patching material on the crack and an eighth of an inch or so around.

IF the operating pressure or the collector is very low, it MAY even be possible to patch the leak with nothing more than a narrow strip of DUCT TAPE!!!!!

Another possibility, but unless carefully accomplished is to "weld" the crack with a Soldering Gun and some scrap plastic from packaging material. The problem with this fix is that you must be very experienced in application of heat from the Soldering Gun, OR you will melt a larger hole in the collector tube than the crack was.

Regardless of patching method, it is CRITICAL that the cracked area to be patched MUST be CLEAN and DRY BEFORE applying any patching material. Good luck!
