Ahh I think I know what you mean, I remember reading or watching a video that the bumps will pull in when it dries, I got a few on one of my walls and no such luck! Hope yours did. As for the reason, I’ve absolutely no idea why it happens

Photo? Don’t forget to spray a little water on when you are doing your final trowels to help your trowel glide over it without pulling it up (may be what you are describing?)

seems even manufacturers are going to need to retest or reformulate their products for our planets ever increasing temperatures

Really interesting that, not what I expected. So essentially there are losses and the sunnier it is the greater they are, but even then it’s minimal and saves buying another inverter.

wonder how that comes about? Just can’t imagine it from my own install. Have you done this and observed the output difference?

I believe Tesla powerwalls do this, but it’s a hard thing to achieve in the UK as in the event of a power failure, any generation or potential export should turn off or island, and for that reason most don’t operate the whole fuseboard on backup, rather just a backup socket for emergency loads to be plugged into. Maybe someone else knows more about this, but mine certainly doesn’t as an AC coupled. Don’t agree with East and West connecting to same MPPT, my east and west panels are both active in differing amounts simultaneously, and in winter east does far better than west. Either use a separate inverter, or get a triple MPPT one to handle all 3 strings, these are widely available as normal and hybrid. A good question, do you get the feed in tariff? If you do then don’t go hybrid, as it will wipe out a lot of your income.

Work out the airflow capacity you need for your volume, and then double it so you run your unit only ever at 50% (less the better for noise), and then keep an eye out on eBay, loads of units come up, many are brand new and much less than buying from a store, they’re often mis-specified units which get sold on to recoup losses

I don't think any of us doubt the climate changes naturally over time, this is well documented, same with CO2 concentrations in the atmosphere, but as you see from the graph above, we are very much in unchartered territories now with CO2 concentrations, within the last 800k years, and not just that, but the speed of that change is where our climate emergency (and it is an emergency) will come from. All living things can and have adapted to change, its what we do best, but over 10's if not 100's thousands of years, not 10s to 100s of years, thats the difference here...at least thats the way i see it anyway. If the temperature follows the CO2, as it always has done albeit with some lag, then we are in for a very bad time. Your sea level argument, wrong again. The world isn't under water yet, as we are currently at the 'normal' peak over hundreds of thousands of years, but as above, that temperature will likely go skyward in the coming decades

Have a word with yourself... Yes the world is a corrupt place, and people are out for their own gain, but this type of post is why the right wing parties are edging ever closer to control.

We hit 36.5C here in South Yorkshire on the 26th, the humidity was an absolute nightmare, glad of the cooler weather now but it seems the next heatwave is just round the corner 😭😭

Have they got that wrong? I thought it was a high pressure heat dome? Pushing the hot air down on us. Buckle up, theres another possible mid July!

After this last heatwave I’ve got some fabric samples of outdoor UV stabilised shading material, of two grades, and am considering making some fixed awning/external blinds for the windows which bring in a lot of heat in summer, an attach them with neodymium magnets, one stuck to the frame and the other sewed into the fabric itself. Originally I was going to get outdoor roller blinds until I costed them, about £600 each for the bigger windows 😬 fabricsUK is where the samples are from and it looks good quality, around £20/m and 2.67m wide if I decide to make them I’ll post about it on my blog. I’ve got the external blinds on some of my velux windows and it knocks a good 10C off of the centre pane temp of the 3G ones, I think they were about 1-2C above air temp compared with about 12C of the non covered in same position. 2G ones that effect is even greater (showed around 50C with inside and outside blinds closed, without outside blind I seem to remember they got closer to 80C)

Just looks like its a zinc roof which goes round it, can't see anything different other than that

Absolutely, like I said ChatGPT output isn’t 100%. Given the likely cost of these thermally isolated brackets and the overkill, it’s likely I’ll use a timber structure behind the cladding to space out the wall and also hold the insulation, which will be one layer horizontal, next layer vertical etc until the vertical cladding

yeah have considered horizontal, have always had a preference visually for vertical. Think vertical should be easier too as the longest length wouldn’t be even half as long as the widest for horizontal. I got some samples from millboard of their new cladding range, but wasn’t overly keen and they couldn’t guarantee it would last even 10 years but said it should last much longer. I will certainly be looking at cement cladding boards too before I decide. Did consider uPVC but someone across the street from me has it on their dormer and it’s warped and split all over, so that’s out. timber would be hardwood or modified softwood and would then get no further treatment from me, I quite like the silvered look it gains over the years.
