6 FAQs about [Repair the backing adhesive of photovoltaic panels]

Should you replace PV modules with a failing backsheet?

Apart from the cost, the environmental impact of prematurely discarding PV modules long before their normal end-of-life is substantial and should be avoided. An alternative approach to replacing modules with a failing backsheet is to repair them.

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.

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 silicone sealant protect solar module backsheets?

An Austrian-Belgian research group has developed a flowable silicone sealant that can be used to create an insulating and protective layer on damaged solar module backsheets. The scientists used a special sealant that is known as Dowsil 7094 Flowable Sealant and which is produced by U.S.-based silicone adhesives and sealants provider Dow Corning.

Can solar panels be repaired?

This repair technology can be done in the field and is an alternative solution to module replacement. Over the last few years, several solar park operators have observed a premature degradation of some photovoltaic (PV) modules.

How do you repair a broken backsheet?

Several repair solutions have been proposed and are being studied. 5, 6 Some solutions involve applying a tape or a new backsheet with incorporated adhesive on top of the damaged backsheet, whereas others simply consist in a coating material that is applied on the backsheet to create a new insulation and protective layer.
