Gear is ordered!  extrahappy

Cheers for the support lads, I like the humour! Smiley

I nearly ordered a pylontech us2000 as well but I don't like to reward myself excessively and I do fancy a Winter as is. Well as is with the 3rd string installed.

IMO, with your storage heaters, you don't need an extra battery for winter. Next summer on the other hand, if we have another month like May 2020, your batteries will be full and your 2nd system will be sat there in full sun, doing nothing.

What a problem to have eh? House stuff done, Batteries full, HWT topped out, storage heaters maxxed, Leaf fully charged then the 2nd system switches off.....

I'm sure by then i'll have found other uses for any excess. At the moment SWMBO and I are solar cooking a Chinese Plum sauce with fruit from one of our trees, THIS is the stuff that matters! Smiley

Next weeks install will feel like DejaFu. Slightly nervous about lifting the tiles to fix the hangers as i've not been there before. I'm sure it will be fine! Smiley

Up and running! I'll never be bored of that switch on and it just begins outputting. Got a few bits to tidy up and rails to chop but it's working.

Thanks Tod, my son helped today and it flew together in 6 hours. Leisurely from now on in the finish off, just wanted to see it cranking!

Thanks Nowty, worst part was installing the rail hangers as awkward angle to be working at and hard to get power into a push to move tiles. SWMBO said it all looks fine and as if it should be there so that's a win. Interested to see how far into Winter this whole array will output meaningful power for? There IS one more roof space that could take another 4 panels but I think i'll leave it here. Smiley 25 seems like a fortuitous number for panel count?

I am hoping to see around 6MWh per annum. The original system outputs 4MWh but this new system doesn't have the split aspect hindering it.

These last 3 panels are on the best piece of roof for output that I have. Ironic that they went in last but just goes to show we learn as we go. Smiley

Had a look at outputs on both systems. Using the Solaredge system as my calibration I matched today's output to 10th Sept at 16.20 today (8.9kWhr on each day). I then checked against the victron system. Matching same date to today on the victron expanded system I would expect to see a 50% increase in generation. Turns out it's a 60% increase. Can't pin it down for sure as the two systems are so different in orientation and I can only match outputs but it looks good for the new string and it's tilt. Smiley (3.81kWhr on 10th, 6.09kWhr at 16.20 today).

I predict that around next April you'll be replacing that Victron 150/35 with a 150/45 or a 150/60 and flogging the old one on fleebay. hysteria

Then you'll need another one or two more Pylontech batteries to take the increased current. fingers crossed!

What are ye like? It will be interesting to see how long we spend bouncing on the 35A controller limit next Spring. That'd be the decider. This game is never-ending. At the moment, feeling quite chilled!

Whole shebang generated 18KWhrs today which at this declining time of year  is great. HWT is seeing a few kWhrs again, house needs taken care of and batteries were full. Smiley That'll do.

Well,
That's the job complete. The Chofu could not stay in the structure so has been moved outside and feed/return hoses extended. These Woodburners will take 6 deg water in the morning and 1500 ltr of water at that to 40 degrees by evening and all with no moving parts.

All new timbers treated to sympathetic colour match the 12 year old structure

SWMBO got stuck in and broke up the lines nicely with things. Been seeing 21 to 23kWh the last few days. 11kWh of that from the remote system alone.

All hail the solar gods, they have been kind to me during all this.  genuflect

I'd advise anyone looking for a bit more solar oomph to strongly consider this option.

Hi Joe

Good to see the finished solar roof and that it and the additional roof panels are performing well.

Turns out Nowty has mind reading skills too. On a boat trip yesterday out here in SW Turkey and came back to house a little merry. My subsequent fifty quid under offer for a pylontech 2.4kWh has been accepted! Smiley

When we return home and all leaves have fallen I shall be carrying out a little cutting back in the forest. It's now 10.45 hrs b4 my gear is outputting properly due to shading from council trees.

Been in touch with local council but as much use as tits on a bull for response. They've had their chance, my turn now. Smiley 23 years we've lived here and my goodness haven't the shadows encroached in that time with no maintenance from council.








Pretty cool though, if we hadn't installed this extra system we  may have let the encroaching shadows slide. Bought a wee Einhell battery chainsaw to compliment the petrol one. I'll report back on its performance in improving our daily solar gain when we get home.
We have also just passed the 10MWh generated mark, 3.25MWh of which has been stored and discharged thru the battery stack. We are beyond happy with our decision to go solar.
