Panasonic HIT panels and Solaredge power optimizers.

I like your thinnking, you'll do well around here!!

As an aside, I don't know if the Geo is worth it? Mines (Geo Solo PV) has fallen over an dGEO are not interested as it's outside the warranty (5 weeks outside.

Also have an Owl and aWattson, with an OEM coming shortly I hope.

Both the Owl and the Wattson are for sale if anyone is interested?

I would rather just use the SMA webconnect functionality but we are having the panels installed on our garage and its not practical to run an ethernet cable unfortunately, which shouldn't be an issue but I have an irrational dislike of ethernet powerline adapters.

Wifi an option?

Defintely irrational, love my hompleugs!!

We have some frustratingly fabulous foil lined wall insulation that keeps both the heat and the WiFi in.

Google home plugs, my solaredge inverter is 35m from the house but is connected via them,using the home electrical wiring as a network

Do package prices vary across the country as drastically as house prices?
I've had three suppliers quote for 12x 330W BenQ panels, SMA inverter, Geo II, iBoost, installation including bird proofing and the lowest price was just under £7k rather than just under £6k.

Hi. I don't think you are doing as badly as you think. Those BenQ 330's cost about 20p/Wp more than 'normal' panels, so that's £800 extra to get 4kWp into a 3kWp space. [Edit: compared to 4kWp into a 4kWp space. M.]

Not sure what bird proofing costs, but Geo II and iBoost must add another £300+, so comparing to a £5.5k install, you might not be far off.

Whilst £5k (comparison for simple and easy install) is a great target, not everyone will get there, but being in the ballpark is what counts.

Mart.

House AND garage ?

If it's just the house, try putting a (hardwired?) WiFi repeater on a windowsill facing the garage.

Or of course you could run a length of CAT5 cable underground in 'trunking' (don't go mad with real trunking, use a length of garden hose) from house to garage or even suspended from an overhead wire.

Just been advised we probably can't fit 12x BenQ on our roof as they're 4.6cm wider than the LG panels. (1046mm vs 1000mm)

A new quote for 10x 330w BenQ is more expensive for less kW than the 12x 300w LG system so it looks like we'll have to settle for 3.6kw (3.66 if we went for the 305w LG panels). Our garage only suffers a small amount of shading from a neighbouring house late in the afternoon, having 10 panels would allow us to mount them away from that shaded edge but I think I'd rather stick with the twelve LG option.

Instead of an SMA inverter, why not get a quote for solaredge instead. Solaredge is great for shade management and comes with the added bonus of lifetime online monitoring(that's what my homeplugs are for)

I did get quotes for the Solaredge but as running the ethernet was gong to be awkward and the shade is only an issue at the end of the day in spring/winter it didn't seem worth the extra £400ish.
Some of the SMA inverter support Bluetooth which doesn't seem to as affected by the wall insulation.
