John -

How is your patch holding up? We encountered a similar situation
Friday with our solar panels. When I turned on the solar to heat our
pool, a foutain of water spurted from our roof. After climbing on the
roof to examine the situation, we found 3 small slits in one of the
panels. Like your solar system, we inhertied the system when we
bought the house so we don't know the model or manufacturer either.
Our panels are also 'flat', not tubes.

I look forward to your feedback. If your tire repair kit and glue
worked, we are going to try. Thank you.
