Don’t have clue about the cause. Perhaps substituting a different material (like Lexan) will help solve the problem going forward.

For several years, I have had a thin flexible 50W solar panel velcro’d to the top of it. The spacing between the panel and the bridge that supports the traveller was initially tight, so I ground the fiberglass with a Dremel so the panel would fit underneath as it slid. But I noticed that however much I ground it, the spacing would decrease over time, so that last summer, I had to lean on the panel to get it to fit underneath. Once out of the sun, it would relax some, but the situation got worse as the summer wore on. I pulled the whole sliding panel and brought it home and the plexiglass is clearly warped. I can’t see how the solar panel on top would cause that to happen because most of the time, most of the plexiglass is out of the sun, covered by the solar panel. I guess I am going to have to replace the entire panel as it is now seriously warped in some areas. If anyone has any thoughts on what caused this and what to do about it, I would appreciate the advice. Thanks- Dave S/V Aries 1990 C&C 34+ New London, CT
