In case the OP is worrying It's important to understand this has very little to do with mounting the beasts and everything to do with manufacturing tolerances. I had some panels which were so poorly made that the ali strips were not making a good enough contact with the cells (series connections) and the higher resistance resulted in sufficient local heat to shatter the glass completely. Very rare but immediately noticeable since the output goes down a wee bit. ????

We have about 9 metres of U shaped worktop and a 1 x 1 M island and it's always chock-a block. Don't put too much faith in what your wife says "will do". She is probably thinking of keeping the cost down.

Serving hatch?

Panel expansion is not normally a problem especially with brackets of thinner metal that can flex a little. What can happen is that, if the glass panel is a tight fit in the frame, the glass can crack under the thermal strain. I have a panel which did just that. It's like crazy paving. The panel stull works just fine because the silicone underneath is undamaged and the cracks seem to be still waterproof.

Brilliant Pity they didn't do that 1st time.

And strong enough for megawatts of solar panels. You seem a bit light on worktop space in the kitchen areas.

Global House seems to be the go to place for solar equipment these days.

A bit like this? Perhaps you could adopt something similar.

Good thinking but I didn't do that and it still works. Do you think the infrequent use may be the reason why it works without plastic or shade cloth (whatever that is)?

Those solar panel mounting brackets are a neat idea. I notice they are fixed to the trough section of the roof material. Do I also see silicon sealant and rubber washers? Good bit of engineering there.

Before my house was built, it was nothing more than a 1 Rai x 1 metre high island of soil. I had a truck wide slope adjacent to one corner which went to the original land level. I guess the slope must have been about 15º. After the next rainy season when I saw it again the slope had developed some water channels and was eroding. My fix was a large lorry full of mixed aggregate which we spread over the slope filling canals and making a decent looking gravel road. We smoothed it a bit by driving my car backwards an forwards on it. That was about 11 years or so ago. The stones are still there but invisible below a layer, added by nature, of soil and grass which took about a year or so to develop. It's a totally non-professional approach but it works.

Alfred Hitchcock would be proud of you.

Another solution.

Yes. Or any where else where the metal is ≤2.5mm thick.

Also at Global house but three times Lazada price.

Are you not using some of these? They clip to the edge of the panel for holding the cables up nice and tidy.

When the sun is a bit low in the morning and later in the afternoon, you can be sure there is a significant difference . At midday the difference is about 5% but the shading of the dust in the earlier and later parts of the day can reduce the output to half what it should be. I did mine a couple of days ago in the early morning and the output shot up by double. I use slightly soapy water and one of those mop thingies that can spin around in it's bucket. I will need to revisit to remove a few spots of bird droppings which seem to be etched into the glass.

A milliohm meter could be useful, but to check one of these joints properly really calls for high current and a volt meter. e.g. Pass 50 Amps through the joint and measure the voltage across it. Application of Ohms law will then give you the real life resistance and power loss

Phew. Thanks. You really had me worried for a moment.

The Earth is what!?

Un-skilled people who join this forum are more advantaged than yer average DIY'ers. There is stacks of help and core knowledge here so there should be no reason not to jump in and do it yourself so to speak. Help and support is here if needed.

So it must be down to you that we are having such a dull, overcast day today.

Please excuse but what is SPD?

My old chemistry teacher looked like that too but this was pre Alf Garnet. Ours got the name "Bilko" as in the cartoon character Sergeant Bilko.

If you are anywhere near Buriram, Ruangsangthai have some 350W (I think) for 3,250 each.
