I don't know where they got their costs. 24 240W panels costs R60,000 giving you 5760W. That can give you over 1.5kWh per month which is way more than an average household uses. Shop around and don't take the word of any installer. If you don't agree with their breakdown quote show them the actual prices.It is bit expensive to part with R233 000 therefor eskom will continue to bully us until a cheaper than this comes to play
Loadshedding is driving the off-grid solutions while the prices are probably driving the much cheaper grid tied systems. Electricity price is going up while technology price is going down.The more they raise the prices, the more people will find solutions to cut themselves off the grid or at least reduce their load a lot.
Not yet It is surprisingly difficult to get anyone to assist with battery banks, inverters and the like...
I was very impressed with the Carte Blanche story on Sunday night and the guys who have done it. Definitely the way to go.
If you can afford it.
I understand them to be more cost effective in the long run. Solar generating plants have started using them.More than likely cost and market.
My fear. If Eskom loses its paying customer base there would be no one left to subsidise the nonpaying users. It would be hard to justify still supplying them.This whole thing is pushing all the big paying households off the grid / making them reduce demand via gas etc.
Which leaves illegal connections and subsidised users...
If Eskom pushes too hard on the increases then they'll be left with even less money than before...
Geoff Vickerstaff from Plan My Power said that even at a cost of over R200,000 per household, you will save money in the long run.
“If you are to amortise the capital amount over 20 years, the cost is around R2,000 per month,” he said.
Another problem: "Real-life example: Big family home completely off the grid"That calculation is so broken.
R233 000 + replacing your batteries twice in that 20 year period at a cost of R72 000 each time (R154 000) = R387 000
R387 000 financed over 20 years with the current prime interest rate of 9.25% = R3544 p/m
Which makes your total payment for the system over 20 years (240 months) = R850 657
If you are currently paying R1000 p/m for electricity now and Eskom increases their electricity cost by 10% every single year for the next 20 years, you have only paid a total of R687 299
If they increase at 15% every year for the next 20 years, you will have paid R1,229 322.99
So in a nutshell, if the the total increase in electricity cost over the next 20 years is at or below 12% average over those years, then you will pay almost exactly the same amount and save nothing.
I on the other hand only pay around R550 a month for electricity, LED lights, Heatpump, etc help for that, so the system makes absolutely no financial sense to me.
