Mono vs Bifacial ?

At 13.64p per Watt and over 25% efficiency this one is a steal. Might not have sheer size needed though.

And free delivery if you buy as few as 2 panels.

oh, I was actually looking at these (535watt)

my thinking being long term higher output was worth the additional cost

I'm not set on any particular panel yet, if planning don't let me rebuild/extend the knackered workshop the way it was originally built I'll probably redesign it a bit

They are great panels (the 585's). I've got 3 of them as our bootroom roof. A heck of a W gain for little money and I'd happily buy them again. Just pointing out efficiency & per W price.

I bought them as they were a great size for the project and the area 3 covered made a good sized room below. Be aware though that they are beasts and you can't really run up a roof with them like you can with the high 300, low 400 panels. It took two of us to handle them into position on a 1 storey flat roof.

Once we switched them on though.... Instantly hit the limit of the solar controller (since upgraded).

As Nowty also pointed out, free delivery on the smaller panels, I collected my 585's.How much Wattage are you hoping to put up Knighty? You know you can.oversize panel output in comparison to your inverter capacity?

Have you got 3 of the 585's connected to a Hoymiles Joe? If so, any chance of a link to which one you had and now have? Wanting to look at adding 2/3/4 panels to a shed roof/ground next to it. (apologies for the sidetrack)

[Fintray]

Until Joe confirms or otherwise I believe they are connected to a Victron charge controller.

[Joeboy]

As Fintray says the panels are tied back to Victron 250/80 charge controller.

Last year, when looking there was plenty of Hoymiles 2000 4T available from Germany. For that I'd defo be counting on a dedicated line back to a correct rater breaker on the cu.

Thanks both, something and model to look into

depending on planning... I'll have space for 20 south facing and 20 north facing

If I have to get planning permission (which I probably will) I'll change the design a bit and go all south facing... something a bit like this (image from google)



heating system is gulping down oil like it's going out of fashion, I want to install as much solar as possible now so it's there done when we're old

Sounds like a great plan Knighty. 11.7kW of solar will make a massive splash. Excited for you. In the North we now only really have a couple of dead solar months. Dec & January. Even Nov & February produce something useable when a larger scal system is gathering. The rest of the Year is at no cost or profit. Which then pays for the dead solar months. The further South you are, the better it will.likely be.

Personally I'd like to squeeze in some more insulation as that's the ultimate fit & forget.

Groundmount PV is a non starter? Although that image is pretty good for easy access cleaning,
