Solar panels and battery - any real world reccomendations?

[Mercenary Keyboard Warrior]

Yeah those two quotes aren't far off what the best have been for 3 or more months give or take a little.
If you cannot secure a sensible lower price elsewhere they arent so bad that they fall into the daft type area

For the sake of comparison, our system installed in June (and July 'cos of waiting for some bits):

• 11 x Trina Vertex S 400W panels
• Huawei 3.6kW hybrid inverter
• Huawei Luna BMS
• 2 x Huawei Luna 5kW batteries

Total (inc. installation and scaffolding) - £12,500

920kWh generated since end of July and very happy with it.

Solar company owners must be rolling in it. Right time, right place.

I'm thinking about accepting tbh.

Infinity Renewables - Infinity Renewables

This is the installer if anybody has any experience with them, first glance at reviews look good for installations but bad for customer service.

Guess you are on the Hampshire scheme because I just got mine as well.

The product specification page has more details.

Suntech 390w Mono all black panel
Growatt inverter no mention of size.
Growatt battery 9.6kw

Price doesn't seem that outrageous compared to my last quote

Yes, in Hampshire too but a different installer - mine is Home Smart Energy

Spec sheet is here, but they use - https://ichoosr-cms.azureedge.net/content/2022/10/13/20f71404db3141f597d051e75ce1ecd2/HomeSmart_solar&storage_final.pdf

JASolar 405W panels
PylonTech US3000 batteries
SoFar KTL-G2 inverters
Sofar ME3000SP battery inverter

As a rough guide, that hardware would cost:

• Panels: £1400 - https://www.pluginsolar.co.uk/?prod...bb-percium-half-cell-silver-frame-solar-panel
• Panel inverter: £500 - https://www.tradesparky.com/solarsp...XXuA5fOicd9zUaZEp9qU-EWUFzzhkSFgaArPwEALw_wcB
• Batteries: £3600 - https://www.pluginsolar.co.uk/?product=pylontech-us3000-3-5kwh-li-ion-battery-module-48v
• DC Inverter: £740 - https://www.pluginsolar.co.uk/?product=sofar-me3000sp-ac-charger-inverter-battery-manager

So a rough material cost of £6000 and a quote of £14,000 to include labour and scaffolding?

This installer definitely picked the bargain-basement solar gear to be honest.

[Edit] No mention of DNO either, or what size inverter they would fit

 

[Hawk Tuah]

Don't forget the 'extended warranties'. For at least until the company dissolves and the owner moves to Spain next year.

Got my quote also, same specs as your guessing its the same installer as were both in Hampshire - Infinity Renewables?

16 panels and 9.2 kWh battery £14,899

Google reviews for Infinity Renewables aren't great.

What's with the £150 deposit? Is it refundable if you don't proceed after a proper survey?

Edit: from the information pack

You will get a full deposit refund if:
• You cancel the agreement before the roof survey is carried out, regardless of the reason
for cancelling.
• The installation has to be cancelled for one of the following reasons:
1. the system does not physically fit on the roof;
2. it would be a mistake to install the system, for example because the solar panels
pose a risk to the roof;
3. custom work or unforeseen additional costs are required to successfully install
the system, and you do not agree to this;
4. the roof ’s orientation turns out to be unfavourable;
5. there is too much shade on the roof, meaning the system would not be able to
live up to the expected generation;
6. the roof contains asbestos.

Yep same. Reviews are mixed to say the least!

Yeah looks a bit ropey tbh.

Isn't this what the insurance guarantee is for?

This guarantees that your workmanship warranty is valid even if your installer ceases to trade in the future.

People in Hampshire area could try the same people @SoliD and I used: https://www.solarpowerful.co.uk/

Not always easy to reach but the end result was good and they were competitively priced.

Just did a quick tot up on the additional costs on my quote as its a similar size to yours but was fully detailed.
All the roof mounting, switches, cabling etc are nearly £900 on top of the above items you have listed there.

 

[Hawk Tuah]

Even better. You get both.

I tried, he came out and did a survey and I never heard another word from him again. It was a pretty straight forward set up too

 

[Hawk Tuah]

Ultimately, every quote is going to seem over priced compared to those from early in the year. Demand is soaring. Why wouldn't they charge more.

Email Luke at solarpowerful.co.uk, I had a similar problem but he did get back to me after I emailed him. I think they're extremely busy!

Luke is who came out and did the survey. I probably will chase him for a follow-up, I was waiting for the Solar Homes stuff before deciding next steps

 

[BUDFORCE]

Worst day so far today, generated only 1.1 KWh.

 

[HungryHippos]

Got to 9.5kwh in the end generated, but the sun came out in the afternoon

Yeah worth it I think, was my best quote by far.

 

[ketma]

Just wondering what your actual daily electricity costs incl. standard charge are? (for those with battery)

 

[casper_uk]

Worst day so far today, generated only 1.1 KWh.

Glad it's not just me. I thought it was broken at first when I checked and saw 1.32KWh for the day. I guess this is what people meant by winter generation being tiny.
