How to repair a scratched photovoltaic panel backsheet

What happens if a PV panel is replaced?

If voltage or current differs on a replacement panel, it cannot simply be integrated into an existing string and new electrical layouts need to be made, which involves planning and engineering work. DuPont has come to the rescue with its PV Rescue Tape, at a fraction of the cost of panel replacement.

Can a backsheet be repaired?

Backsheet failures have plagued the industry, causing hefty financial burdens to many asset owners. DuPont has launched a product it says allows for easy repair of modules. The new backsheet is simply glued to a cracked backsheet using a strong adhesive. The butyl rubber has previously been used in other applications.

Can a Tedlar-based band-aid fix a solar backsheet failure?

DuPont Photovoltaic Solutions, though, has now brought to market a solution which promises an easy fix – a Tedlar-based band-aid for modules. The materials supplier estimates that, in Europe alone, about 6 GW of solar capacity is affected by backsheet failures.

Can Tedlar PV rescue tape help extend the life of solar panels?

“There is great demand from both module manufacturers and asset owners for repair products which can help extend the usable lifetime of solar panels. Our specialized repair process, customized for Tedlar PV Rescue Tape, reduces costs versus a full replacement of affected panels.

How many GW of solar capacity is affected by backsheet failures?

The materials supplier estimates that, in Europe alone, about 6 GW of solar capacity is affected by backsheet failures. After years of service in humid or dry, hot or cold conditions, and under severe UV-light irradiation, backsheet materials can suffer from defects, with some materials more susceptible than others.

How does SC-refit fit a new backsheet?

The service crew can fit the new backsheet onto the module using a proprietary tool or there is the opportunity of sending modules to Sc-refit’s repair centers. “We are delighted to be partnering with DuPont to support this much-needed solution for the PV market,” said Sc-refit chief executive Roberto Gacitua.
