6.49kW from a 5.6kWp array

I just noticed that my array was producing over 6kW. Looked outside to see the back garden list up as if there were arc lights on it. A weird glow. The sky is cloudy so that, when the sun does peek out from the clouds, it lights them up with spectacular effect!

So now I have a better feel for what kWp actually means. I was seeing (briefly) 6.49kW from my 5.6kWp array (14 x 400Wp).

There is an interesting article about this effect in PV Magazine.

Update

Since I wrote this I glimpsed 6.92 kW, albeit briefly. Anyway, it looks like, it the UK midlands 120% of the kWp value is entirely possible. It will be interesting to see what summer brings. We won't benefit from the cloud reflection as much but, in terms of power generation, of course it is the SUSTAINED power that really matters.

Automation tasks underway

I have the following automation tasks underway, in various stages of completion: If there is a suitably inexpensive timeslot overnight, use it to top up the batteries to 100%. Using this, instead of solar, will allow more solar to be exported at 15p/kWh. Inexpensive slots during sunlight hours are not as useful because I can't export at the same time as using electricity from the grid. If there is not a suitably inexpensive timeslot overnight, top up the batteries from the grid during the period coming up to peak time (which is usually fairly reasonably priced). Make sure any battery charging from the grid is definitely off before the 4pm-7pm peak rate starts. When the electricity price goes negative, boost the hot water temperature using the heat pump and immersion heater. This is a way of benefitting from being PAID to use electricity and storing a little of it in the form of hot water. Change the colour of a lamp in the kitchen to reflect the current electricity

No, YAML ain't, but what is it?

YAML is said to stand for "YAML Ain't a Markup Language". This unhelpful acronym (and brazen use of the old "GNU = GNU is Not Unix" joke) doesn't really help in understanding YAML as it pertains to Home Assistant. Well, in this context, YAML is a way of defining the hierarchical configuration settings that drive Home Assistant. So, suppose we have some settings such as: Lights: Left: Brightness: 4 Colour: "Red" Right: Brightness: 6 Colour: "Green" Fans: Extractor: 2 YAML is just the thing to define such a hierarchical structure. For the moment, don't worry too much what these might represent. Consider, however, that we might want the actual settings (such as 4 or "Red") to be controlled by some variable quantity derived from something else within the system. In this case it would be useful to be able to replace the settings with snippets of Python code. And this is, effectively, what H

A new strategy, a new approach to automation

As I explained before, I was very wary of automating my system beyond what the inverter could do natively. As a retired elecronics and software engineer there is too much danger that such an endeavour would become a slippery slope. Well, I now have one foot on that slope! What prompted this change of heart? Well, during the last month we had some periods with VERY low Agile prices and it got me thinking about how I use my generated solar power. One way of looking at it is to look at the "opportunity cost" of the solar power generated. The incoming solar power, thanks to the sunk cost of the system, comes in at 0p/kWh. However, I can sell any excess back to Octopus at 15p/kWh. That means that, effectively, any solar that I use is costing me 15p/kWh - inasmuch as I could sell it if I want to. This way of thinking leads me to consider a different strategy: What if I were to charge my batteries on a cheap rate at night and, during the day, export most or all of my solar at 15
