Hello there m, I'm trying to work out if going solar will eventually incur a better ROI than what I am currently predicting

I use about 400 to get 500 kwh a month and due to the setup we have in our small town do not get loadshed. Currently a solar setup that would most likely suit my needs would be around R60 to R70k

With current electricity prices shelling out that cash is really a hard sell for me. It could change in the future as both equipment and electricity will only get more and more expensive.

So how much do you think the average increase year on year would be for the next 7 years
 
Sorry, dont have advice to your question, just making sure I understand you, you currently paying R400 for 500 units? That seems to be very low.
 
Sorry but it is impossible to calculate ROI for this because of all the complex socialist rules and tariffs that are constantly changing. My guess is that you will not really save much money, probably lose out a lot, but you will get electricity during load shedding.

he is saying he uses around 400-500 units

Very confused.

inverter and battery alone would cost R60 to R70 odd or only panels no battery

The system you get with R60/R70 is tiny not anywhere close to your needs. You looking at closer to R120-R150k atleast.


PLS STAY AWAY FROM SCAM SITES THOSE SOUND LIKE SCAM PRICES

Also ROI is not everything you cant put a price for great quality of life

ROI is everything and you can put a price on everything, including quality of life.

Haha I guess to a degree. But ROI meant nothing to me or it didnt factor in me ultimately pulling the trigger for solar.

Well there is really nothing but monetary concerns influencing my decision as, stated in OP, the light stays on (unless of course the infrastructure get damaged, them idiots repairing our aging water lines gets drawn to cables like magnets)

I also figured 8% and used it as such in my calculations. Although the concept will be awesome, I just can't find a justification for installing it.

I think any pure calculation should also factor the following in:

1. ANC stellar track record on maintaining things.
2. ANC funds available to keep burning those diesel generators.

That what was the basis why I decided to go solar. I look at it as buying a R150-R165k car, that gives me a measure of security against being reliant on what other parties can or cannot do.
 
What about the calculation for the "solar tariffs"? It is impossible to calculate these, remember it is illegal to produce more than you consume, and what about cloudy days? Nersa is suggesting that solar houses pay x10 for grid power and levy. How does one take that into calculation?
 
We are at the mercy of an unfair socialist system, I would say hold off until it is actually possible to calculate ROI. Do the minimum for now, buy solar for only load shedding, do not think it will save you money. The socialist system will take your money even if you buy solar.

Can you link the source for this?

Yeah I simple ignore this, I will just switch eskom off if I need to pay more than 10x for power. This month im looking at 0 eskom reliance anyway and typically 98% off grid I can make that 100% if I need to.

Cant pay for something I dont use.

I had similar usage before i installed solar and based on my average production of 15units per day i estimated that it would take me 7years for the system to pay itself off. This was last year before the increase in tariffs so it will take less time.
 
Keenly observing these threads... :)

Regarding increases: we have both history and current behaviour to base this on. Annual average seems 8-10%. and appropriate for reasonable estimations/calculations. Voters will not accept higher.

The base costs that Eskom and muni's lose from keeping elec cheap/affordable for the masses are not and will increasingly not be on a sliding scale i.e. it will not be consumption based. Network charges, demand levies, time of use etc. will be always either be fixed or skewed to the 'tax paying' users and increased at higher factors than entry-level consumption. Then if one tries to be 'clever' and 'disconnect' Eskom with a smile and "I'm going off-grid ek se bru" middle finger, then they will simply tax this elsewhere. Example: no clarity yet on the speculated 'tax' for your PV install or similar, but you can bet your bottom dollar that collect it they will, whichever way.

Also, the best case scenario in terms of simply breaking even (i.e. not being in the green) looks to be between year 7 and 8. This is a system that can guarantee 75% of your required electricity on average over a year with no additional investment/maintenance added in the 7-8 years. It also relies on you staying put right where you are and not moving house for that term, as you will not recover the investment from a sale to a new owner and uninstalling and moving the current system will once again draw out the breakeven with another year or two.

For me, with loadshedding-convenience already taken care of by a basic gennie, there are simply way too many uncertainties at present. I'm re-assessing quarterly.

BTW - why is no-one moaning about CoJ's 10% hike in water & sanitation for 2022-2023?? More than electricity and sewerage charged at fixed rate on property size - much more of a concern to me and not possible to intervene without 'n boor se gat.
