Out of curiosity's sake, what is the general savings you are getting by going solar.

Before solar average 1000 units a month, after solar 400 units or 0 if you have gone completely of grid.

Maybe eg.

BS: 1000 units
AS: 400 unit
System: 12 x 450 panels and 5kw battery and 8kw inverters
Comments: Went gas hob, still on electric geyser but on timer.

Don't want to go into a debate on the ROI, we all are clever enough to work that out for ourselves based on our own financial needs and positions, just wondering what kind of dent solar is making on consuming on net power.

I'm sure you have seen my system we use more power now as we don't care about consumption as the system was specifically over specd.

But in saying the above we use 5 to 100 units max from eskom a month. Around 800 units a year from eskom. This could be zero if we wanted typically 3 rainy days cause this.

Typically generate 25-35 units a day.

Have a solar geyser but still top it up from our main solar. Also everything else in the house from normal geyser to oven to induction hob all run off the solar. System hasn't skipped a beat in almost 600 days and generated about 13000 units since Nov 2021.

System 8kw sunsynk 12x550kw panels 4x5.5 kw hubble batteries

Was about 700 units now down to 340 tops. Though average out at 250, but do run a lot more things so would be a lot more.
 
I am super consistent for the last 20 years.

Between 150 and 200 units. Summer or winter
 
dropped from say an ave of 1150 units per month to around 450 ,dont really pay it much attention as long as its working .a lot of it was hot water and lighting .still run the fridges and freezers on mains as well as pool ,borehole and compressors .

Lol. Nope.

I must say, reading what consumers bills are... i dont want to know what 1000kw now costs

What exactly do you power that consumes so little ? A geyser alone would eat that allocation up.
 
I went from 450-500kwh to 150-200.

I need another string of PV though as my batteries are not fully charged by the end of the day in winter. Then I should be 100kwh Max a month.
 
Before: 800-1500 units / month
After: 200-350 units a month
Gas cooker
2x5kw inverters, 3x4.8kwh batteries, 18x335w panels

Would like another 3-5kwp of panels but its not a need right now - we can get through the night with that we have
