Solar panel production figures

[Ron-ski]

Once you have all your batteries, how much do you think you'll be exporting anyway? You're going to generate more from april-october than your batteries can store and that you can use no? Are you bothered about exporting at all?

I can import/export at 8kW from the batteries, and export whatever the SolarEdge system is generating on top of that not accounting for house loads. I have DNO permission for a total of 11.68 (8 on the Victron & 3.68 SE) which I doubt it will ever reach. So in the three hour cheap rate window I could charge the batteries with 24kWh not allowing for losses, same goes for the peak export window, plus whatever the SE system is generating, but depends on what the house is using.

I'm perfectly happy exporting what we don't use/can't store but I'd prefer to be paid a decent rate for it.

Battery was full by midday, currently exporting at almost 6kW, 25kWh generated, 8.1 of that exported.

My figures for today are a bit off because VM have been up and down like a man on a pneumatic drill

Same here, really affected the SolarEdge uploads, but that appears to have caught up now, Victron stores and uploads when it has a connection, so just messed up PV Output really.

44kwh today, which is a little bit more than yesterday,exported 24kWh.

 

[Ron-ski]

as after a month of waiting now, still no export MPAN.

I hope mine doesn't take that long, two weeks tomorrow since Octopus requested it.

 

[Ron-ski]

Not sure what most of you have been playing at today

22kWh forecast, 40.07kWh generated and 23kWh exported. Third day in a row with over 40kWh, could I make over 1000kWh in one month?

No sun to be seen here. See Kent had plenty of clear skies till the start of the clouds I had this morning reach there around 4pm

There was some thin cloud all day, did much better than I expected. Tomorrows only forecast for 9.2kWh, I'm going to take a chance and not charge the battery.

 

[Ron-ski]

What are you all using for forecasts? Solcast?

I use https://forecast.solar/ although I have it integrated into my Victron system via Node Red

 

[Ron-ski]

But not before I reveal the Solar Dragon of Ron-Ski which I just need to make some finishing touches too....!

I'm waiting in anticipation Hows the plans coming along for the panels on the out building? Did you draw it in Easy PV?

 

[Ron-ski]

b) garden room - flat roof, so based on easy pv, I reckon 12 might be the most efficient and just accept it's south south east facing.

Your using the word efficient

South south east will work well, I'm pretty impressed with how well my garage array works given the the split directions, low angle and some shading, it's basically doubled my generation, although it is 4.74kW compared to the house array which is 4kW.

 

[Ron-ski]

Speaking of Flux - to those of you that have switched, how long did it take for them to move you over out of interest?

I was switched to Flux import on the 12 March, had confirmation today that my export will start on Tuesday, so from applying to getting paid will be a month. My previous exports were on my FITS payments with another supplier, so they had to apply for a generation MPAN which took just over two weeks.

If Octopus already pay you for exports then it's pretty quick.

 

[Ron-ski]

Terrible weather today, but finally filled the battery at 16:30, somehow generated 18.2 and exported 0.9kWh, forecast was 9.2kWh. I haven't charged the battery from the grid since Saturday morning, used some grid over Saturday night until the sun came up on Sunday and been grid free since

 

[Ron-ski]

Me to, currently 5kW of generation.

The Victron system has a time to go for when discharging, but not for charging, so I built my own. Although its based on power at that moment in time, it doesn't average over a period, but it gives me a rough idea.

The text will also show discharging time to go as well.

 

[Ron-ski]

Whos he???

Someone not too far from Katie, clearly they've either got data upload issue's or something is wrong with the installation.

 

[Ron-ski]

How's this for an AC load, and minimal grid draw?

If you want to know why I had such a high grid draw, then look at my build thread.

 

[Ron-ski]

I have my eyes on the 40kwh club....

You'll get there, won't be long now, you just need a day of sunshine - you had 38kWh back at the end of March, given a full day of sun you'll smash 40kWh's.

I'm eyeing 50kWh as the next milestone, and a 1000kWh in a month

 

[Ron-ski]

42.97kWh, 19 exported.

 

[Ron-ski]

Been a rather poor day here, overcast all day. Generated 18.5kWh, didn't even manage to fully charge the battery though, currently at 57% (wont last through the night), Mrs decided to she'll use the ovens most the afternoon

 

[Ron-ski]

Now the suns gone done there is not a cloud in the sky

But tomorrow looks good, roll on Tuesday when I can just fully the charge the battery every night, then hold until 4pm and not worry about, just keep enough to see us through those 3 hours.

 

[Ron-ski]

Battery dropped to 10% at 1:15am and we used the grid until 7:20, drew 3.7kW which was the first significant power draw since the previous Saturday night/Sunday morning.

Lots more cooking today, weather's great so hopefully can end the day with a full battery.

 

[Ron-ski]

Despit my wife's best efforts, she couldn't defeat the sun today, 14kWh consumed, battery full 10 minutes ago, 1.4kWh exported and 26kWh generated today so far.

 

[Ron-ski]

41.7kWh generated, 12 to the grid and consumed 19, battery currently at 96%.

15kWh forecast for tomorrow, though given the weather forecast I'm not sure on that, but I'm going to take a chance and not charge the battery.

Starting Tuesday morning, I will charge the battery and hold until 16:00, then force discharge down to 20% SOC

 

[Ron-ski]

Spent most the morning averaging around 700w, it finally started to brighten up around 13:30, battery is currently at 44% so I think we'll have a enough to see us through the peak period espeicially if it stays bright, we've got leftovers so the ovens not required today.
