Solar advice needed

[CTBP]

I am almost ready to pull the trigger on solar power, just awaiting approval of a loan to fund this project.



I don't think my house has ever used more than 30Kwh per day even in winter, in summer time it is between 20 and 25.

I will potentially add aircon to my property at a later stage so I would need some extra built in for that purpose.

My budget will be about 200K but I could maybe stretch it to 220k, is it worth adding more panels to this would 8 be enough?

Should I add more panels to run the geyser or is it better to go with a solar geyser?

During bad/rainy days I would obviously have to rely on Eskom, my aim is to be 80 to 90% off grid.

Any advice welcome.

My installation is currently happening and it's basically exactly the same.

Oh and I'm leaving the geysers off.

I've just ordered a similar setup, except for getting 5.5Kw's of panels. We have a 200L geyser used by 3 people and were advised to run it from the Sunsynk inverter. If it proves to be too demanding, I'll probably opt for a solar geyser later.

I installed a similar setup. 8kw sunsynk, 7x460w panels and 5kwh battery.
I also added my geysers to my home assistant setup to have better control of the geysers.

I've dropped from about 450-500 kWh per month to 200kwh of eskom usage and don't have to worry about loadshedding.

My next step is to add another 2 batteries and another string of solar then I should be mostly off grid.

Having good control of the geyser makes a big difference.

If you can afford a solar geyser go for it
If you not you can add a timer to your geyser

AHHHHHHHHHHHHHHHHHH

NO

Dont ever get the solar geyser esp as you going solar add the money to panels power the whole house not just hot water.

I need to sticky this rant!!!!!!


just going to copy past this one

Hi all, I am finally getting round to making this thread. After loads of research and another bout of load shedding I finally decided to pull the trigger and load shed Eskom. Prior to going solar I already had all the lights on LEDs, house is kitted with energy efficient appliances and...

How much is the actual installation costing, if I may ask?

But you already got solaradvice... ... ... i'll see myself out

System seems decent - i would add more panels to cater for winter and cloudy days - maybe increase to 12 and go 6 per mppt. Geyser can be run on that as well

Just add timers on the geysers and they become solar geysers

It depends on your consumption patterns, you want to go 80-90% off grid. Many households around 70% of consumption is outside of solar hours (that's me), so you're talking about a daily consumption of 20,25,30kWh but you have battery capacity to store 2x5.12kWhx0.9 = 9.22kWh. If you work from home or are able to move loads around, etc. that may work well for you though.

Adding more panels might be a good idea for winter and cloudy, etc. days. 8panelsx545Wx6hours of sunlight = 26.16kWh max. I usually de-rate that by about 30% to get a more realistic value and account for winter, so call it more like 18kWh in a day.
