GoSolr vs Solar

[Kosmik]

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?

I could be wrong but I have not seen panels output at that type of efficiency. Depending on your inverter setup , yes, during the day, as long as your panels have load, it will send power. Load can be ether the essentials, non-essentials or battery. You set what it is. Right now my home is running on the solar and my batteries are topping up. Thats a 200ah bank ( around 10kwh ). But yours should easily be able to charge that battery, I just think it might not carry you through loadshedding and I wouldn't want to use the bank for nearly anything else until you sure ie: use some at night normally.

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?

Keep in mind, I believe on prepaid its not as simple as 1 unit = 1kwh. Unit changes time of day etc.

Ah I didn’t know that

I could be wrong, was trying to help my brother in the ECP and apparently thats the case.

Huh..?

Explain yourself please..

1 unit is 1kWh on prepaid.. the only thing that changes, is the cost of a single unit based on how much units you have bought within the same month, which is based on a sliding scale.. more units bought, increases cost per unit and then resets at the start of the new month again..

No they don't change on time of day.

 

[Kosmik]

Ok, like I said, wasnt sure just know its not flat. So its the cost per unit that changes, not the unit itself then.

This changes things. Also if your geyser is using 8 something isn't right. The only thing I've got on Eskom is my geyser and stove, those only come up to 8 units a day if the stove/oven is used.
18 units a day is 750w an hour not 75w, if you were using 75w an hour it would be 1.8 units. Remember 1 unit is 1kw which is 1000w.
So at 750w an hour your battery would be done in just under 3 hours, you'd need to double the batteries, double the panels.

Sorry to be a pain about this, but it is literally impossible to use 750W an hour. The concept doesn't exist. That's like saying a light bulb was at 75% brightness per hour. Or the chip was running at 2Ghz per hour.

A better way of stating the above would've been something like:

18 units a day is constant usage of 750W, not 75W. If you were using 75W it would be 1.8 units. Remember 1 unit is 1kWh which is 1000Wh.

750wh sounds about right.

ok should've maybe done per hour not an hour?

No, its consistent units = KWh but the price per unit goes up the more you buy.

@Dolby I spoke about my experience with GoSolr in this thread -> https://mybroadband.co.za/forum/threads/solar-rent-to-own-anybody-using-them.1234181/

But, TBH, if you looking for short term, I wouldn't advise.

 

[P924]

Watt is Joules per second. Watt per hour would equate to Joule per second per (3600) seconds, which is a rate of change, like acceleration = m/s²

 

[Speedster]

Nope, it's not per (divided by) hour, it is times hour.

750W of power for an hour uses 750Wh of energy.


Power (P) x time (t) = Energy (E), or in units Watts (W) x hours (h) = Watt-hours (Wh)

If on time of use meter

Normal prepaid just counts unit no ratio

Don't know if any municipality does time of use curently

Ok maybe I've messed up something - and I'm going out now, so can't re-calculate gain .

Are you happy with the 20-25 units per day though?

I'll sort out when I'm home

 

[leon.davibe]

Not sure if it is a thing (maybe some areas are different) but can't imagine as all are governed by nersa

There was suggestions that this would be instituted in the last price increase , but did not happen

I suppose they wanted to just pick one battle at a time

ie this time round the levy got introduced

Or maybe this is just a thing on the low levels of prepaid ie if no levy you already pay a higher rate per unit than with the connections over 20a that have a levy

And recall (salt) that on the indigent users that get a super low rate with 20A connection for 500 units (salt) amount of units and then pay more for units above 500 units in a 30day period

What's with all the salt?

As most of you know, the last 3 years has been hectic for me financially and I did my best to avoid inverters / solar ... until now

I begrudgingly needed to buy a small Ecoflow inverter (and another 2 mini inverters) a few months back for my 27" screens / Internet to work during load shedding (I work from home)- and they work perfectly, if we stick to schedule . But we never do in my area and over the past 48 hours I've had a grand total of 8 hours power. Last week was 37 hours out in a single go. My inverters die if we don't come back on after a load shed. I have to buy data and hotspot ... toss out food from fridge ... and it's just a really shitty situation.

So now I need to generate power to work without the grid and two options :

1) GoSolr which on the face of it, seem to be well priced at under R2kpm for 8 x panels / 5kw inverter / 5kw battery

2) A friend of a friend of a friend that knows my situation put something together where I can 4 x panels / 3kw inverter / 2.5kw battery @ R60k fully installed .

What's the better option?
Rent the bigger system from GoSolr or pay the R60k and own a smaller system?

Unsure if GoSolr has an install price before the R2kpm kicks in though

EDIT : I can't change the title, but basically rent larger vs own smaller system

you can look at the offer from Webafrica as well which included installment plus COC , came across it this week and it seems you can pay it off sooner without penalties.
