Are solar panels worth it

Stubod

We are also considering "going solar", we have had a couple of quotes, and after some calculations using their figures I would consider that it could be a bit "marginal", based on how much electric you can generate (and sell back). 

As well as the installation costs, (which do appear to have come down), you need to factor in the cost of replacing the batteries, and inverter, (assuming you have them) at around 8 to 12 years. 

But after saying that we are still considering going for it anyway, as I like the idea of being "energy free" during the summer months. (NB We have electric / E7 heating, so we don't currently have any boiler on costs.

You should be able to put 5kWp of panel on your roof for £5k or less. Assuming the roof faces south-ish and isn't under trees or in the shadow of neighbours, that system should generate at least 4000kWh a year.

Do you want to share your quotes here?

If you're being quoted more than that, we can probably find you a cheaper installer.

11 off Solar Panels - Aiko Neostar 2S+ 460W Dual Glass

Inverter - Lux Power 3.6kw Hybrid inverter

Battery - Hanchu 5.12kw

£11k......

Also 2nd quote, similar price:-

11 off Hengdian group DMEGC Magnetics 450 Watt panels,

5Kw Sunsynk Inverter,

Sunsynk W series 10.6kw battery

ND we are a "convential" 2 story house, so would assume £1-2k for scaffolding which is included in the above prices quoted...

Those quotes aren't great. You've got maybe £5k-worth of PV plus another £2-3k worth of battery. So £7-8k all told as a target price, not £11k.

If you're  budget is £11k-ish and you're in England or Wales, @Screwdriva can probably find you an installer who can fit more, better panels and a 13.5kWh Tesla Powerwall 3 for that sort of money.

Over to Screwdriva, when he notices the tag! Or you could send him a PM.

Sorry to say - have to agree with @QrizB. That's some seriously low end kit on offer. 

£11K should get you 12 X 500W Eurener bifacial panels + Tesla Powerwall 3 (13.5kW) and a 10 year workmanship warranty and bird netting as well. You can do much better than the above quotes. Feel free to DM me and I'll do my best to help!
