Sealant

Remove the sealant from the photovoltaic panel

The Gentle Heating Method is an effective and safe way to remove the plastic film from a solar panel by softening the adhesive underneath. The protective film is typically applied during manufacturing to shield the panel from scratches and debris, but it must be removed before installation to ensure optimal sunlight absorption. . One essential aspect of safeguarding solar panels is effective sealing. Identify the type of sealant, 2. Yet here we are, dealing with adhesive residues from protective films, mounting tapes, or even bird deterrent strips. A recent NREL study found that 23% of solar panel efficiency losses stem from surface contamination. . Maybe wait for a hot sunny day (to soften the plastic) and use a plastic razor blade to gently scrape it off. Possibly a scrubber for non-stick pan may help. I'd wear a giant hat and sunscreen too. On almost any other surface I'd use a heat gun, but that may damage your panels.
