Ronski's Solar & battery DIY build with whole house backup

[Ron-ski]

I was absolutely knackered last night, after spending the day installing a couple of roof rails, its certainly very sunny up there, as I got quite a bit of sunburn, will need plenty sun cream today, as its going to be even sunnier.

First row of hooks in.

The hooks have to spaced out so the hook doesn't rest on the tile below, so I've used some 5mm aluminium between the hook and rafter, there was also a hole in the felt, so I patched it in.

Likewise the back of the tiles have to be notched out, so that also clears the roof hook.

I got two rails installed yesterday, this picture and the next were taken at 18:36.

This picture shows the shading caused by the chimney, and next doors roof. There will be four panels in that area, in landscape, so the shading will only affect them later in the day, and they are on their own string in parallel with the other two strings, so won't affect them.

I wasn't impressed with the rail joiner, so used that and made up my own much more substantial joiner, using 5mm aluminium and some left over rail clamps from the garage build, which fitted perfectly.

Well, its 10am, so best I go and get some more work done.

 

[Ron-ski]

Got the third rail up, and also the cable entry done.

There's probably not many installers that do this correctly.

Another thing I forget to mention yesterday, is when installing the roof hooks, its very important to drill pilot holes, failing to do that could mean split roof rafters.

Not as much progress as yesterday, but I need to allow a full day for the top rail, in case I need to take the ridge tiles off.

Looking very professional. Its a pity those roof hooks have the rafter plates in that orientation, vertical would have suited a lot better and less risk of weakening the rafter as the fixings could have been spaced well apart.
So when is the chimney and unused TV aerial coming down Ron

Good work, I imagine it reminds you that crawling around on roofs is a young persons game!

They are done like that so the hook can be offset from the rafter to match curved tiles, which would increase the twisting motion of the bracket relative to the rafter, should probably have extra wood screwed to the rafter, but that probably doesn't happen often.

We still use the TV aerial, have a log burner as well, not that we use it.

Thanks, certainly is a young person's game, or at least someone who's a lot fitter than me, and with better knees - I'm mid fifties, with bad knees.

And then there was 15 panels.

Top job ronnie……

 

[DRZ]

Hopefully the weather holds so you can get them up nice and easy!

 

[Ron-ski]

Got a new entry on the VRM tonight.

Although obviously there's no panels on the roof yet.

 

[Ron-ski]

And then there were four.

Just need to get some panels connected up, and of course modify my Node Red code to take into account the new solar charge controllers.

 

[Ron-ski]

This weekends progress.

Got the top rail installed for the 8 panel array, which meant removing some ridge tile - if I didn't the roof hooks would be 300mm lower down and the panel overhang would be too much - how many solar installers remove ridge tiles????

All four rails in place, although I need to square them and level them.

Made a start on the roof hooks for the 4 panel array, got the cable entry install, and 5 hooks in.

I'll be glad when this bit is finished.

 

[Oldman2]

Bet you are proper sunburned now, well done anyway, soon be finished

 

[b0rn2sk8]

Good work.

Get some Wet and Forget on the roof before you put the panels up, it will bring it up nice and take off all the moss and liken

I presume you've used it and its good stuff? I've never heard of it before.

Yes, I used it on my garage roof which was absolutely covered in big chunks of moss and lichen. It took a few weeks to do its thing but it looks like roof tiles now.

I had a bit of a fail on my part as I forgot to order it when my main solar array was installed and scaffolding was up on the house which would have made treating it A LOT easier than now. Needless to say I haven't done it now.

 

[Ron-ski]

Here's a picture of the power wall all cabled up.

I still need to sort the wiring for the battery heaters (the messy wiring bottom right), and mount the 48v/12v convertor, but that can wait for now.

 

[Ron-ski]

Its raining once again, so I thought I'd update the thread.

Yesterdays weather was horrendous, so it was time for some work inside the house, one of the reasons I.m fitting more solar is that we want to move away from gas, first thing to go is the gas hob with an induction hob being fitted.

The cable for the hob was run in last year when the garage work electrics was done.

The hole for the hob was a little too small, and needed to be enlarged, only problem, the worktops are 30mm thick granite, but I don't let that worry me!

Although I've marked the front for cutting, it was decided that would leave a gap at the back of the hob, which would be difficult to clean, and as I could cut the back, that was what we did.

So it was just the back and the two sides which needed cutting, which was a very messy job! Luckily I have a saw for cutting, it uses a 115mm diamond blade.

Hole cut to size, and an extra air vent cut in the rear of the cabinet.

Squaring out the corners was quite tricky, but managed to remove sufficient for the hob to fit.

Luckily my bargain induction hob fits - it was ex-display and I got it for less than half price.

As for today, I got three more roof hooks installed this morning. By lunch time it was getting quite windy, and some clouds were rolling in.

The top row requires some ridge tiles removing, so I'm going to allow a full day for that, weathers not looking good tomorrow, chance of rain and 17 mph winds, so may leave that for next weekend - I'll see what the weathers like tomorrow.

PS. Wife said she's taking her mum out for lunch, and I can't miss out on that, especially on a bank holiday.

I got induction hob fitted when i moved to this house 10yrs ago. They are brilliant to be fair

 

[Ron-ski]

We did the kitchen in 2005, and I made the decision to fit a gas hob, my brother shortly after did their kitchen and went for an induction hob, and I realised I should have as well, so its been a long time coming.

Ever since we removed the gas hob a month ago now, we've been using a portable double induction hob, and its been very good.

 

[b0rn2sk8]

Nice job, cutting that kind of work top is pretty risky.

Our ‘de-gasification’ started with an induction hob, we the. Got the solar and ended with the heat pump.

When I did our hob it went into an oak worktop when I refit the kitchen. Easy enough to sort out with a jigsaw and a decent blade.

We haven’t looked back since getting it although it slightly annoys my wife you can’t use the cheap pans anymore.

So how long until you pull the trigger on a heat pump? That £7500 grants got to be burning a hole in your pocket!
