they're in

24 panels 11.8kw total capacity
...
three days ago we sent 30kw to the grid

Those figures do not make sense. How are you sending back more than your total capacity?

 

[WTFH]

Those figures do not make sense. How are you sending back more than your total capacity?

Because there's a difference between kW and kWh.

Edit: 24 x 490W panels = 11,784W. For UK calculations of approximate output, you'd multiply that by 3 this time of year, so in a day it would be about 35kWh generated. In summer you'd multiply by 5.

Ah, so he's used the wrong units.

 

[milanbenes]

units are fine I just lazily didn't have the h on the end

all good the panels are amazing

WTFH is spot on with the calculations

yesterday the inverter produced 45kwh

the house used 11.80kwh

batteries were topped up with 6.8kwh

we sent back to the grid 33.50kwh

and we took from the grid 0.3kwh

what's not to like

much awesomeness

Milan.

so you get your money back after 12 years and 50 SqM of your garden's a disaster area for that time.
very good.

uhhh no

it's february and our consumption from the grid, for example yesterday is 11.8 / 0.3 going to be for yesterday 1/39th of what it would have been without the panels

do the maths

difficult to swallow I know, and that's how it is

rough calculations from the performance we are seeing this month look like pay back will be 5 years

anyway,

it doesn't matter does it lol

Milan.

p.s. and don't worry about the garden, plenty more space where that came from
