I had a contractor paint silver coating on my roof and some of the aluminum paint spots/speckled onto my solar panels. How can I remove the spots - what solvent is safe to use on solar panels? Can I just use paint thinner?

The panels are Sunpower X22-360 with Tempered Glass High-transmission tempered anti-reflective.

The paint is 169 Karnak Non Fibered Aluminum Coating.

Will using mineral spirits damage the AR coating on the tempered glass?
