[RE-wrenches] The Genie Lens

[Dana]

Hey there Peter,

In that I owned the largest [2-3 person] window tinting
company in N.AZ almost 30 years ago, I feel qualified to
enter a comment here.

The bubbled film is a direct result of not enough or
possibly no UV blockers in the adhesive for window films.
The bubbling is a direct result of adhesive failure.

There are many excellent manufacturers out there that
produce an excellent film product with proper UV block in
the adhesive that easily last the life of the car or film.

When buying a film application product you want to go for a
no-questions asked Factory Lifetime warranty from a
reputable and financially secure manufacturer.

However, my question for this application, would be will it
last the 25+ year life of a PV module?

Thanks,  Dana Orzel

Anybody know anything about these claims?

SolOptics, the solar division of Genie Lens, has created a
new lens design
that improves solar PV performance by 12.5 percent. The new
thin-film design
can be applied to any PV module, just like a sticker. The
new design is
created by the company's ray tracing software that embosses
microstructures
onto thin polymer film. That film can then be applied to
solar panels much
like tinting film can be applied to a window. In testing,
the
microstructures in the lens improved PV efficiency by 10 to
12.5 percent.

I think the claim of a "lens" is complete hogwash. As for
being an
anti-reflective coating, that might work, but reliability
would be my
concern (UV, heat, moisture). Think how many tinted car
windows you have
seen with blisters all over them?

I am posting this for a client who is a really dedicated
solar enthusiast
and occasionally emails me with questions about solar
technology.
