Solar Panels?

We're booked in for a mid-May installation, and the company have suggested it should be completed in a single day. Perfect timing to maximise the benefits during summer.

Thanks to everyone who shared info and experiences, as it likely wouldn't have happened without input from posters on this thread.

Make sure you have a smart meter in place before the install. I had a nightmare with EDF on this.

All done already. With Octopus.

Have you modelled how much you will lose on the compromised install because they cannot be bothered with a slate roof ?

You didn't read my earlier reply.

Just starting to look into this for the garage roof.

Had a quote for 10 x REC Twinpeak 5 panels ( so 4.15kW), SolarEdge optimizers, inverter, power mgmt. No battery or immersion control.

£7.2K all fitted - does that seem a bit high?

Seems in-line with my quote that I shared recently. Any reason why you decided to go without batteries?

I've just had a revised quote including a 10KWh battery: £15.5K (this is for a 10 x 415w panel system)

Out of interest, why are home batteries so expensive per kWH compared to EV batteries?

~£6000 for a 10kWH battery - £600/kWH vs Model S 100kWH battery : £8,700 = £87/kWH

I bought a 61kwh battery for £22,500 and got a free car 12 months ago (MG5).

The answer is, people are currently prepared to pay the prices being asked.

I'm hopeful for a significant reduction over the few years to coincide with me retiring and investing in one.
Still a chance V2H or V2G will make home battery tech redundant in the nearish future too.

That quote feels quite a bit more than mine. I'm paying £3k less for the same battery capacity and 3 more panels. Is there anything else in there that has bumped up your quote?

The answer is the whole is a rip off

This from 2 years ago:

It's still got power optimisers in the quote, which maybe add ~£800. A local installer with good reputation/warranties, and I think the kit quoted (Solaredge, REC panels) is all fairly 'premium'?

Is that quote really 2 years old? They're stating you'll use 1242 kWh of the power you'll generate and save yourself £420. That works out to be 34p per kWh which is more like the current rate than 2 years ago.

If that includes all installation and other hardware, then it does indeed suggest that prices have gone up.

[dmsims]

To answer both:

Quote was from Nov 2020 and included everything

2 Local suppliers were 10-15% less expensive

[EddyP]

Best recent quote I've had is:
14 No. panels - 5.95kW total
2 No. Pylontech 4.8 kWh batteries
1 No. 5kW inverter

All installed etc. for £11,980

Is that quotation tool still available?

Unless I missed something their payback calculation was based on amazing foresight or bad data. Probably the latter? Sadly all too common.

[dmsims]

No, sorry but I did take screenshots of a few different combinations

As the weather is turning a bit sunnier now, it looks like we're on target to have 0 consumption from the grid since the the middle of last week to the middle of this week - and hopefully continuing on all summer,now (yeah, right. English weather).

That's a lot better than I'm getting at present. Are you happy to share the installer details?

Shame we have to pay standing charges!

To be fair, it's £160 per year, and it guarantees you a supply AND a customer. I expect to get most of it back in exported energy.

Absolutely, that's not lost on me. Esp since I'm currently on Octopus Go, so get no payback for export.

[SoliD]

Can't you sign up to the 4p one at least? Is it worth looking at Flux if you're regularly exporting a lot, yes you pay more for import, but should be offset by the export during the day.
