Glass solar panels

Afternoon all,
Last weekend a mate's solar panel fell over in the wind down at Limeburner's flat and smashed the glass panel. Lucky for him it still seems to be working. (Multimeter on the output both amp & volts)

Is there some way he can return the panel to new with a tougher glass panel, or is it toasted?

I have seen this happen before and the poor bloke chucked it into the bin as he was told the replacement glass panel wouldn't replace the dry environment that was manufactured.

Cheers

If its still working I would source a bit of perspex and replace the glass that broke.

make sure you take the brown papaer off the perspex though or it may not work

Anything except the correct glass will degrade its performance. There are only a couple of glass manufacturers that produce glass that does not attenuate the ultra violet (UV) radiation. Ordinary window glass or other "transparent" alternatives do not pass much of the UV radiation. The visible light spectrum is only a part of the radiation that excites the solar panels.

If you can not replace the glass with the original type you will be better off just using some Araldite to seal up the crack.

Yep saw it happen 2 years ago at Lawn Hill. It just stopped working. We tried to follow the tracks and they all looked intact?

Anyway it was b_ggered.

We seem to have had a few reports lately of the glass breaking on solar panels in what would be considered "normal situations"?

It does make one wonder if they are robust enough for our typical travel/camping environment? It's a lot of cash to throw in the bin for a broken glass.

Umm

Maybe the posts are placed by 'uni-woteva' panel owners ...

Bonz,
Do you need to use any of that silica pouches to suck up the moisture once you have sealed the panel?

smear some neutral cure silicone over the cracks in the glass - better than nothing

Nah mate,
All the glass fell out.

In that case ignore my suggestion above. If the glass is not recoverable then try anything. a half efficient pannel is probably better than nothing. Use this panel to supplement a new one.

Solar panel glass is capable of surviving the heaviest hail storm but an impact when they fall over is another story. This is one of my major objections to portable panels. You are better off installing a bigger panel than needed for angled operation and laying it flat. When you do that you have it operating all day and not just when you remember to put it out.

LOL! Well you didn't specify! :-)

But it does work if you have just "cracked" your glass - used it a few times to salvage otherwise buggered panels :-)

*usually* the panels are contained in between two sheets of a plastic membrane as well - and heat sealed - so moisture shouldnt get to the actual cells - will depend on the individual panels manufacture method though.

Cant hurt trying some new glass :-)

You would need to 'Laminate' a sheet of clear perspex onto it. This would require a lot of silicone so you get a clear joint similar to making a fish tank.

It is important that you keep it rigid as you may have already noticed that the cells are now flexing and will break.

It is not possible to remove the broken glass.

What size is the panel ? It may not be worth the cost and effort.

Regards

Derek.

"perspex" changes the solar characteristics, tempered glass is a better choice
