GoSolr vs Solar

Ok that might be fine for that I guess. PC and monitor only 60w?

Yup - as above .

I use a work laptop day to day, unsure of that power.

But regarding the rest of the figures and what I'm getting, not bad ?

Do you have itemized pricing?
Could you scrape another R5000 and go With Daye 5kwh inverter, since your house is small that should future proof your install.
Then as money come by you add panels and battery. Pylontech is easy to expand.

I don't think I'd need to expand - my place is tiny and not my forever place

If not a larger home locally, I'll probably be overseas in 2 years
 
@Dolby it depends on your risk appetite.

If you can afford or are willing to pay the system, look at buying one with good brands but a decent small home system ( 5/8 KVA deye, 2 x 100ah bats, 10ish Panels ) with install is around the 180k-190k mark.

There are options to rent, rent to own, own with maintenance etc.

Regarding GoSolr, install is one months rent upfront. Same if you choose to upgrade the system later for whatever you choose. Purchase options are after three years but not really worth it as its quite expensive but does go on a sliding downward scale per year thereafter. However, keep in mind replacements become your problem once purchased, currently batteries are warrantied for 10years, inverters I think 15. During their rental, all kit is their problem with regards to performance, maintenance and replacement.

Perpetual contract, cancellation is a fixed fee, sounds expensive but it is a lot of work to come and remove and reconnect all your wiring etc so TBH I don't think it unreasonable. Flat payment monthly, no surprises. Problems with the system for them to fix.

I'm with them because I am not willing to add more to my debt burden at this point in my life and see it as a "assurance" type purchase, ie: pay a bit more with the intent that replacements are funded out of that as well when EOL.

Should be fine, but remember fridges do have higher start ups and when the compressor runs it can be higher as well.

You must have the most efficient PC in the history of all PC's.. 60w for both PC and monitor..???!!

Newer gen pc can go as low as 25w if just doing office work with momentary spikes

So depending on generation

That idle usage has come down
ie an older pc will idle at lets say 80-90w

Not so old 45w

Old = more power

Edit , with some bios changes (down clocking) you can get a old to come down to 45ish watt but the new i could not get any noticeable difference
Naturally only for office use

ie the low power states have gotten a lot better lately
 
Or you could consider. 3-5kw inverter generator for extended outages?....
 
I would not rent at all

You help pay of the system they own and help them make money from you later

I would go cheap device that may pack up in 5yrs by the time it packs up it will jave roi'd itself

And then just kick the can for nice brand inverter down the line if budget is a constraint

No, rental cost for the two years adds up to about 48k including initial payment and then there is the cost of removal, which seems like it could be significant enough to at least equal the 60k self own option or be even more..

Yep. Removal depends on kit size but its around R17k. I would not go for it short term. Rather get a trolley or something.

Fair enough, given it's not apples-apples. (If the self-own option was equal in size and self-financed it'd be different.)

In fact with such low requirements a trolley + a panel on the lawn is probably enough, in the region of R 20k.
 
Dolby said:
The R60k is a Victron inverter which I understand is already pretty good ?

I dunno that system is really small. And the bat is 2.5kwh, depending on our loadshedding, you may still run into issues.

Fyi, my resting power is around 400-500W ( lights, tv , pcs , deep freeze etc ). So a 2.5 would maybe last 5 hours, more likely 4. And then keep in mind, it has to recharge.

My resting with new fridge and freezer is 150 to 270. It's gone from 200 to 400 which was with the old double door fridge.
Now my 9.6kwh barely bats an eyelid. We went from 4pm yesterday evening to 8am and it only hit 50% which with the old fridge would've been 30%. If you've got old fridges check those aren't chomping

Or existing device with panels stretching the time you can get on its battery

A 3kw with 30A charging can charge 3kw in 4 hrs

And naturally with panels the capacity used from battery would be resuced

Those panels are only 300 odd. If he's going for small, rather get larger panels, especially as they go directly on the tax rebate. My gut is that bat and charge is going to be borderline and no offense to Dolby, but I think he's underspeccing his draw. Large load shedding patterns will kill it.

No offense taken .

My prepaid meter says I use 20-25 units per day ... of that, my geyser is about 8 .

So right calc to get my resting is maybe 18 units / 24 = 75w on average?
Maybe double for daytime use = 150w?
 
Quote also gives this

  • The solar panels will yield around 4 x 375watts x 5,9sun hours = 8,85kwhours of sun energy a day
  • This will allow you to charge the battery (2,kWh) for the evening as well as run your home throughout the day
Does this mean the balance of 6kW (when the battery is charged) is used to run whatever is used during the day?
