Posts that Didn't Happen: April 2026

And on to April - where for the first half of the month a lot of our time was taken up with car issues.  

While the damage to the car was largely cosmetic (paintwork and some minor 'dinks') - we had been planning to trade it in, and as the damage would affect its trade-in value, we rang the insurance people. They advised it should be dealt with on a no-fault non-insurance claim basis, through Enterprise and Incident Management Solutions - so far, so good.

Then we had word that they were classing it as a 'total loss' (a Category N non-structural 'write-off') - basically, given the age of the car, they'd decided it wasn't worth 'repairing'.  After some to-ing and fro-ing it also became apparent that we weren't insured to drive it, without a further MOT and repair work!  All of which left us using the campervan as a 'run around' and finally having to make a decision over whether we were going to go for an electric car or not.

Decision made, and the middle of the month saw us with a full drive - the van, the old car (awaiting resolution of the 'total loss' claim before disposal), and our new electric car . . .  


Next job, a car charger! (Wherein lies a future tale!)

In other news: we continued minor upgrades to the van (boxing in around the rear windows); I finished what I think should be my last consultancy project; our nearly six-year old sourdough starter got a serious mould infestation and had to be binned; we rearranged some furniture, investing in behind-the sofa shelving (for my growing jigsaw collection!), moving the futon to the spare room from the Folly, and the 'kewb' chairs to the Folly from the spare room; and along the way I did a bit of Lego!

An investment was also made in new plug-in 'mobile' solar panels, which with mini inverters, will allow us to take advantage of sunny spots around the house.  

They were a bit larger than we'd taken on board, and in the end we returned two of them, as we didn't think we'd have the space to accommodate all four.  Busy trying them in different areas of the garden to find the best locations!

Towards the end of the month, with some dry weather, we decided to get rid of the yew tree off-cuts from last month's efforts, with a bonfire.  

Well inferno, might be a better word for it - it turns out yew tree is very very flammable, and it went up like billy-oh!  

Martin usually has a hose on stand-by, but it caught him unawares, and we had a bit of a panic before getting it under control.  We now have a rather large scorched patch, and a burnt section of netting on the fruit cage (which we were dismantling anyway so not an issue.)  

On the plus side it was all over very quickly, and it burnt away to nothing - one to take on board for any future bonfires though!

Finally, the end of the month saw us take our first 'proper' trip in the van - staying at a campsite in Llangollen (part of a trip to take Martin's parents to visit family in North Wales).




We had a mostly sunny, if breezy couple of days, with lots of walks - including out to Pontcysyllte Aqueduct (which it was a real experience to walk across).

It was a nice break - enjoyed a few beers and a very nice curry - and got to test the van in a 'real world' environment (rather than my parent's drive).

All good!

And . . . Back to Normality

With our Welsh courses finally finished, it's 'back to normal' life - whatever that is!


I spent a couple of days or so across country with family, helping out with this and that, and returning with a boot full of wood from a tree my parents had cut down in the back garden.  Couldn't take it all in one trip, but will be back for more - should provide some firewood for next year!


 


While I was away Martin took advantage of some nice-ish weather to get out and about, including a fishing trip with his Dad, and a walk up to the University's Penglais solar farm - where the panels are now up and running.  

For the most part though the weather has been a tad unsettled, and with it being mid-school holidays we've no plans to go anywhere or do anything much other than keeping up with the garden, etc. - so it will probably be a quiet month.  

Lots of time to practice our Welsh!

Solar Stories


The end of May has seen continued dry and sunny weather, with lunches by the castle, a fishing trip for Martin, and the usual gardening and household tasks inbetween.


All in all, it has been a good start to the summer - hoping for more lovely weather to come . . . although even with long May days of sunshine we haven't yet topped our best solar production day ever:

2023 is only 3rd in the top 5 list to date . . .

Which brings me to a long overdue 'Solar Power' update (the last posting takes us back to 2020 stats!)

The graph below provides an overview of performance through to the end of 2022, focusing on solar generation.  (With the arrival of the battery in 2021 other figures are a bit skewed by how that works / is controlled, as until the end of this year we are still on something called the 'Tesla Plan' *).





At the time we invested in the solar panels and battery it did feel like something we'd never really see pay-back from, but recent events have seen energy prices soar, and the solar has really come into its own.  Over the summer it more than covers our bills, and that cushions us for the winter months when the solar generation is not so great.

Anyway, here's a nice sunny view of the end of the pier to finish - fingers crossed for more sunshine to come:


* This allows our electricity provider to control the battery, charging it up and drawing down from it as required.  In other words our usage includes power taken from the grid to charge the battery (mostly in the winter months), which they then take back when they need it (and for which we are credited). We still get an export payout or 'Feed In Tariff (FIT)' too, which is a payment direct to us, but now it is for actual figures (taken from a smart meter) rather than 'deemed' export. This has all worked really well, and has meant we haven't had to think about 'when' we use 'what' as it doesn't really matter - we pay the same for what we use, as they pay us for what they take from the battery.  It will be all change at the end of this year however as the 'Tesla Plan' is being withdrawn - so 2024 will be different again.

Powering Up



So today the 'powerwall' came into its own, when we had our first power cut of any duration - not that it was that noticeable as the battery picked up the load pretty seamlessly.


Shouldn't have to worry about storm season anyway! 😊

Storing the Sunshine


And the final step in the 'solar' project - a battery to store the sunshine in (yes, I know that isn't technically correct!).

That should take care of the electric bills - over the summer at least.


Next up - an electric vehicle . . .

2020 Solar Review

A mid-year to mid-year solar blog is proving a bit of a pain presentation-wise - so we've decided to move to an end of year review instead.  We also added a Modbus energy meter to our solar installation in November, which will give us accurate production, export and self-consumption stats from now on - so next year we will have a full year dataset of much more detailed (and hopefully interesting) statistics.

For now, here are the 2020 (January to December) highlights / lowlights for Solar Production.  As can be seen December's really poor weather has resulted in many of the bottom production figures, and May continues to dominate the top 10 list. 

Date Bottom 10
Production
Date Top 10
Production
18/12/2020 186 14/05/2020 26,133
30/11/2020 334 1/06/2020 25,268
11/01/2020 339 05/05/2020 25,254
07/01/2020 379 11/07/2020 25,129
03/12/2020 442 20/07/2020 25,125
21/12/2020 447 31/05/2020 24,931
20/11/2020 464 25/05/2020 24,881
13/12/2020 467 30/05/2020 24,835
28/02/2020 473 20/05/2020 24,701
16/12/2020 533 29/05/2020 24,675

This graph (pre-Modbus installation), contrasts Production with 'Deemed' Export - fixed at 50% 'of the production figure.

Finally we can see the impact  of working from home during the pandemic on our electricity consumption - a comparison with 2019 shows a notable increase in electricity use.   We're not entirely sure why there is such a leap in July 2020, but it is probably due to a combination of factors: family visitors, the end of that incredible spell of sunny weather, and Martin being issued with a work laptop.

See you in a year!

Solar: Two Years On

Two years on we are still generating solar power, and the 'trees planted' are mounting up (although they appear to have changed the method of calculation at some point during the year so the numbers here have leapt up!):


Our best performing day for solar generation was 14th May 2020 when we generated 26.13 Kilowatt Hours (kW-h), with the month of May remaining the highest month for overall solar generation. Below are the Top 10 and Bottom 10 dates for solar generation throughout the year.  May dominates the top 10, and as last year most of the bottom 10 dates are near the shortest day of the year.

02/01/2020549
29/05/202024,675
14/01/2020 617

This is how the years compare.   In the summer months, the trimming of the Yew Tree may have helped to boost solar generation earlier in the day, but it isn't really possible to make direct comparisons from one year to the next as generation is of course hugely dependent on the weather.
