Danesol, you have the same size system as me.
Whats the max watts yours has ever put out ?
The reason I ask is that our inverter is lower specced than yours and wondered if that makes a difference.
Ours went up to 2819 watts a few weeks ago but seems to be maxing around 2200 watts lately probably due to the warmer weather.

Hi there, same here too, did go as high as 2.8'sh but at the moment is hovering around the 2.4 / 2.5 region around midday - hoping to see close to 3 or above in the coming months....

Comparing our graphs, it would appear yours makes more over the full day as mine tends to maximise when out of shade...............

Yeah, we were told our system should hit about 3kw.
It'll be interesting to see if your higher specced inverter makes much difference In the summer.
I have a couple of small panels on our garage roof I use to charge a leisure battery.
They don't reach max output until around mid May.

Same here, pesky North West!

Yesterday - 29th March
Pretty clear all day, 22.87kWh generated
Peak of 3.16kW at 13:50



To this, today - 30th March
Cloudy all day, 5.09kWh generated
Peak of 1.02kW at 14:15



Record to date was the 26th March
Clear all day, 23.47kWh generated
Peak of 3.17kW at 13:45

Our live output from an Owl energy monitor on PVoutput.org ....

Scobo 2.880kW | Live Output

Its showing as consumption as I'm having trouble getting PVbeancounter to upload data from the Owl as generation.
Any advice on this welcome.

My monthly estimate was 286 kw, ts coming to the end of march and ive done 407.7kw. So its been very productive this month

Has anyone got the problem I'm potentially going to have in July/August, my house is super efficient, so consumes around 11kWh in the winter dropping to 8 in the summer, last week on 4 occasions my panels generated 15kWh, so in other words took the electricity meter (old mechanical one) back to around 5 days earlier. So when the panels are working at their optimum in July/August its a very real possibility that we'll be generating enough to consume no electricity at all and possibly the meter will be lower than a month earlier. What happens when you submit a meter reading that's lower or would you simply not tell them and wait until the autumn or winter.

Even more worrying is the system is rated to deliver about 3000, and we consume no more than 3600 annually, so if it exceeds expectations too much, we'll effectively consume nothing.

If you give them a reading less than the previous one, they will likely change your meter to a newer one. Timing your readings so it dosen't look like its going backwards is an option, but potentially fraudulent. Even if you do it that way, your readings will go up so slow they will likely want to do an inspection and change the meter at some point in the future most likely.

If I was in your position then I'd stop using my shower off the combi boiler and start using my electric one. I'd also have a few heaters to balance figures out.
A patio heater would also be good for the upcoming months......

 

[Earthstore]

You are supposed to tell your enrgy provider, as you have made changes to your system by adding a PV system, so as pointed out it is fraud and you could be prosecuted, as far as I am aware that has not happened yet, but you do not want to be the first do you.

Of course, when you notice it is up to you, and if your energy consumption should rise a little so you do not have a negative reading then it may not show up.

I hope this helps.

March was a great month for generation, especially the latter end.
PVGIS estimated figures for March in my area (Manchester M46) were 262kWh, my generation figures ended up at 385kWh so much higher than anticipated at +47%

Best day was 26th March with 23.47kWh
Worst day was 9th March with 1.8kWh
Daily average - 12.423kWh
Generation per kWp - 96.25kWh

 

[FB.]

My system and summary for March:

3.75kWp (15x250W) Kinve KV250-60M, Power One Aurora PVI-3600-UK (indoor model).
Cambridgeshire, facing between East-South-East and South-East, roof slope 40 degrees, no shading.
Usual time of peak generation in ideal conditions: 9-11am.


Target for March: 236kWh
Actual generation for March: 293kWh (+24%)

Best day: 18.4kWh on 26th March
Peaking around 90% of capacity (3.25kW) mid-morning on the best days.

Worst day: 1.6kWh on 04th March

Daily average: 9.4kWh

Not going to be worth mentioning today.
Thick cloud and snow here in Fife all morning.
