PV Quote 12.3KW

primmer10590

Just about ready to go ahead and thought it's only sensible to see what others may think of my quote. We are a high usage household. South facing. No shade.

30x JA Solar 410W
30x SolarEdge Optimisers
1x SolarEdge 10kw inverter
1x SolarEdge 10kw battery

~ £22,000 all in (labour, equip, install)

Any reason, other than local monitoring of each panel, why you need optimisers if you've n shade?

Prices have gone up considerably since the gas restrictions from Russia, then the full invasion of Ukraine, but .... that still looks pretty expensive.

My sister got lucky, in that she had a 10.3kWp install in late summer 2021, so just before things got crazee, and also, already had scaffolding up, but the price was under £9k. It wasn't Solaredge, so a bit cheaper, and no battery, but still ..... my gut says that's that a lot.

If you've genuinely got no shade, the optimisers are an unnecessary luxury.

Personally I'd skip the battery for now and take advantage of the export tariffs on offer.

The bottom line seems a little bit steep, even allowing for the SolarEdge premium!

I suspect there will be someone along shortly to give you a more detailed opinion.

Agreed, purely monitoring, it could be something we go without, I think that's a saving of ~£1.5-2k there?

SolarEdge inverters only work with their optimizers and they provide protection from all sorts of shading. They also allow panel level performance monitoring across multiple roof aspects. I wouldn't swap them out as that means removing SolarEdge, which is an excellent inverter. 

I do agree that the battery may be unnecessary unless you have a household that consumes >4 mW per annum. (Heatpump, driving alot with EVs etc) Would be good to know your annual consumption #s.

Here's the part I suspect you'll like the most. Based on a v. similar quote I've seen recently, you should be paying < £12K fully installed for the following:

30 - Sharp 410W Panels
30 - SolarEdge Optmizers 
 1  - SolarEdge Inverter.

20+ year extended warranty on the inverter. G99 certificate. Add another £~8K for the SolarEdge 10kWh battery if you really must have it.

Based on the >10% difference in price, I wouldn't proceed with your existing quote (unless you live in Scotland where I hear things are more expensive).

Interesting, so the battery is a must for us, I might ask them to re-quote, this was from February and we are just about to proceed. I did try to add up myself using Midsummer and I got to ~£19,000. That included scaffolding, labour, electrician, battery, inverter, optimisers, panels, cables, battery stand, modbus and roof racking. Am I missing anything anything else?

I knew Screwdriva would be along with a more sensible price

Great call! Only thing that gets to me more than Chinese kit, is overpaying for Chinese kit!

I'm firmly in the Solar + Battery group 

Do you know approximately how much kWh you use from 4pm to 12am? 

We use around 7000kWh/year and from Nov to march, we were using the battery a lot more than I had factored in. I'm glad I went with 16.2kWh. 

I'm on E7 and had to do some Charging from the grid till early April.  

There is a recent thread about optimisers and microinverters on here. If you have a South facing roof with minimal shading, any of the above are just fancy, unless you are a data geek.

30 optimisers is a lot of optimisers to go wrong 😂 apparently they have a reasonably high failure rate (2.2% according to an installer of 130 SE systems in Australia)- as long as you’re willing to get some scaffolding up for when that happens (SORRY NOW FIXED MY DODGY STAT!!)
