I’m stubborn and sometimes an idiot, so I chose to DIY as much as possible. In reality, I don’t look at it as work. I can be at home in...

in the UK, the difference between a delivery kit of 15kWh and a pre-built battery with warranty is about $350-400, which is about 20% -...

High quality engineering mockup here - angle ladder supporting spare roofing panel that is standing in for a solar panel. So ignore the...

Pictures. rails not separated by other bracing, but having put 2 (of the 5) on it's pretty rigid because of the framing of the solar...

Ah I see what you mean. I think you're right - but it's not visible so I'll just gently move along and address it if it ever comes up...

was planning to use the cables on the panels and a combiner box. Is there a preference for combining near the inverter or near the...

Yeah - see later posts - am currently looking at one 5kW inverter and one 8kW one - as much as it's simpler to wire to two separate...

yeah realised that: have to add 3.6V to that, which makes it a bit too close for comfort! I assume it's an issue that the spec says No...

You already said it. If that's you're goal. The purpose of over-paneling is to increase your nominal output during overcast/rainy days...

and use them for what though? it's this bit I'm missing - seems I'm fully powered..... and can't add them to the inverter as is to cope...

PV Input Voltage 370V (125V~500V) Open Circuit Voltage - Voc(V) 37.23 12 x Voc = 446.76V Inverter only has 2 MPPTs. But that's...

The maximum I can feed my 8kW inverter based on the Voc is 2 strings of 12 panels (405w panels). However, roof would actually take 32...

yes it's all within the roof (and garage not visible to beighhbrouts or from road). Roof (to be done next) visible to neighbours but...

update - decided to build it without the alu struts and see how strong it is, and take it from there....

Has to be garage roof. Diagram is slightly misleading as noted above - the yellows will be below the reds if they exist. Will also be...

I'm putting solar panels on my 4 degree north sloping. E-W aligned box section garage roof. So in order to angle them appropriately, I...

In case it's relevant for the UK market, had a very interesting chat with Amy for 15kWh of batteries and cases and BMS - very helpful...

It’s been a while since I’ve used PVWatts, but don’t they express angles as tilt from horizontal? So wouldn’t you expect the 35 degree...
