Sure thing. Keep the light source at a 45‑degree angle to the panel; that gives you the most even spread without the glare that happens when you go too steep. For the material, go with a matte polycarbonate or a diffuse acrylic sheet—both block reflections and let the photons through without the slick look of glass. Cut the frame to match the panel, clamp it firmly, and you’ll have a tidy, glare‑free path. Done.
