Solar panel production figures

A pretty good day with 24.2kWh generated and 12.0kWh exported.

The switch to Octopus completed today so just waiting for the export to transfer over and then I can get onto Flux.

Averaging 39kWh a day here so far, which compares 32.2 a day for April.

Thats a nice bump, I'm averaging 23.3kWh a day for May, compared to 23kWh a day for April. It seems like it has barely stopped raining for the last 6 weeks. There is some hope of better weather from the 20th.
 
First 10 days of May here is a bit less than first 10 days of April, weather hasn't been great lately.

Solcast quite likes the next 7 days though, so we'll see if that changes, as it's been known to adjust it's predictions on the fly.
 
Weather's been a bit rubbish here end of last month / start of this (Couple of 6kWh days last week) but it's picking up... I'm enjoying the difference that bit of height in the sun is causing, I'd usually ( only installed since Feb) be seeing a hundred watts best just now but still generating 2kW from an 5.3kW ESE array. If I'd been able to spread the charge of the battery and not have it kick in until I'm generating >4kW I think I'd have hit 40 today (36kWh and 4 hours of 1kW worth of clipping).
 
Recent solar install here currently have the following setup
Givenergy 5KW Gen2 Hybrid inverter
2 x 9.5kWh Gen 2 Batteries
South String 2.4kWh 6x405W DMEG cells
West String 2.4kWh 6x405W DMEG cells

Generated 12kWh so far which has gone straight to the batteries and a wash/tumble dryer.
 
47.74 kWh generated and 39.761 exported.

So much easier now I have this data easily displayed in Home Assistant.

Tomorrow's supposed to be a very grey day, Saturday and Sunday are forecast as sunny though.

I had a spare Intel Nuc, so using that, but probably could have just installed it in a Virtual machine on my server, but not sure what complications that would have caused, so kept it simple.

if i set it up on a spare laptop, is the laptop allowed to go into sleep mode or would it need to be left on permanent and just switch the screen off after so many minutes of non-use??

If you let it go to sleep then HA will be unavailable until you wake it up again. I've got it running on an old laptop ( running Ubuntu ) set to turn the screen off after a few mins. It's a core 2 Duo Macbook and uses 20-30 watts. Not nearly as efficient as something new and low power like a Pi but not terrible.

it does look like a Pi is the best option, maybe i just bite the bullet and get one......but i cheap refurbed laptop has way more power, ram and ssd than an expensive Pi and comes with built in screen, keyboard, mouse etc etc

I mean i can get a refurb laptop for 70 bucks with 8gb ram, 125ssd, hdmi, usb ports, ethernet and wifi etc etc.....a pi is 100 bucks without all the extras needed to run it like screens, keyboard, mouse, cables etc etc

Look into thin clients, or ex corporate mini PCs (dell optiplex micro, lenovo tiny, hp desktop mini), they all have more processing power than a PI, are cheaper to buy, and use barely any more energy.

e.g. Wyse 5070 - can be had for £60, uses 7watts, and absolutely obliterates a pi4 in terms of CPU performance
