I was surprised to see that today. It's obviously not real just the software counting on an inactive system. I'm sure it will work out whichever way you glaze.

Re: ASHP & triple glazing
If you keep the same kWp (with any extra kWp not going through the TGM) you don't need to tell your FIT provider anymore so DIY upgrades can be done. Its only if your doing an extension or reduction in kWp of the eligible installation you need to contact you FIT Licensee.

Re: ASHP & triple glazing
You can buy panels with 25% efficiency so that is 32% more electric out of the same area. If you can buy panels that are better-sized and therefore cover more of the roof then 50% uptick would seem reasonable.Joeboy wrote: ↑Tue Mar 25, 2025 2:43 pmA good question, the oldest are coming up for 7 years (fit set up) and are 19% if I remember correctly. I really couldn't be bothered scrambling about on the incline. My Wombles ethos says they have a lot to yet give!
Worth thinking about.
12x 340W JA Solar panels (4.08kWp)
3x 380W JA Solar panels (1.14kWp)
6x 2.4kWh Pylontech batteries (14.4kWh)
LuxPower inverter/charger

I'll take a run over at the weekend. I thought that place was closed! I have three on s/by in Lossie but I couldn't put 3 up on the roof rack. 1 at a time local will be better.NoraBatty wrote: ↑Tue Mar 25, 2025 3:45 pmHmm.Joeboy wrote: ↑Tue Mar 25, 2025 2:47 pm Vanport has commenced with ground broken.

Anyone got three 4mtr telegraph poles for cash?![]()
Actually.
Give the vale hotel in fyvie a ring.. he seems to have a ton of stuff including telegraph poles in his car park.
What his plans are for them i dont know. Not looked recently as i drive past mind, they may be gone now, but been there 3 years so not likely![]()

Not closed no, but i dont think it will last much longer, locals are much more likely to support the legion if they fancy a drink, and there is not that much in passing trade for them anymore.
Hes taken to operating as a semi kind of scrap yard to bring in some extra cash, which has not helped trade at all as no one really wants to stay somewhere that looks like steptoes yard.
If i head out this week i will drop in and ask for you, to save a trip.

Re: ASHP & triple glazing
Yep, well aware of all of that, hence I've gone from a 4kWp FITS system to a total of 15.5 kWp system.

If you installed a separate system you've never had to tell your FITS provider, as far as I'm aware, you only had to inform them of changes to the FITS system, had mine installed since late 2015.

"Don't worry, as it a FITS you can't do it yourself without losing the FITS payment, You'd need to use an MCS installer,............."
I'm making the point that you don't need an MCS installer to replace your existing FIT system as long as it remains the same kWp as you no longer need to inform the FIT Licensee that anything has changed. The FIT guidance has changed over the years.

Re: ASHP & triple glazing
I didn't realise you no longer needed to inform them of changes, as long as it stays the same kWp, that's another good bit of news.nowty wrote: ↑Tue Mar 25, 2025 8:22 pm You said,

But I do wonder what they'd have to say if it ever come light you'd diy'ed it, given how bureaucratic they can be.
Probably a rule it can only be worked on by MCS certified companyprovided that the installation continues to meet the scheme rules.
