One big challenge for solar panels is that they are made of glass and it happens quite often that this glass breaks. Broken solar panels has cost been very costly and lead to loss of solar energy production. Up to now, there has not been a viable way to repair this, but now a new method has been developed that makes this possible

The biggest challenge is how to repair the panel easily, reliably and cost-effectively on-site. Covering the solar panel with another piece of glass is not viable as it is very expensive, difficult to install and leads to a more than a 50% reduction in the power output of the panel, in addition to making the panel almost twice as heavy! I have tried this repair in my solar system on my house, as I have a SolarEdge solar system installed with optimisers behind each panel I was able to monitor the energy output of the panel over a period of time.

The way to repair it is by covering the whole surface with a clear epoxy silicone. This makes the panel completely water-proof and has less than 10% effect on the power output of the panel.

Here is a step-by-step guide on how to do it.

Step 1 – Lay the panel down on a flat and level surface.

(Damage to the panel can be seen in the bottom right corner)

Step 2 – Clean panel thoroughly

(Use window cleaner. Remove all dirt and oil from handling it.)

Step 3 – Mix two-part silicone in a bucket

Step 4 – Pour the mixed silicone on the panel

Step 5 – Spread it evenly across the panel to the edges

Step 6 – Leave to dry for 24 hours
