Load-shedding may be back soon as Eskom runs out of coal

Get one of these. With the wind today you can power a whole neighborhood

Please tell me you have one or know someone with one .. The information around the web on micro wind turbines shows them as a complete waste of money, I'd be stoked if someone can show me an installation where they are getting close to rated outputs over a consistent time period, so I can give Eskom a carrot

I don't have one, but seen some around. Can't say if they work as per specs.
 
And this while our deputy energy minister is at the climate summit with BEGGING BOWL in hand.
The thing is SOLAR is too cheap and quick to install and no long term kickbacks.
How convenient now.
PS the deputy President is in Russia on sick leave probably trying to appease Mr Putin.
 
Yeah, meanwhile in Cape Town solar users are facing tougher regulation: https://www.privateproperty.co.za/a...more-difficult-for-cape-town-home-owners/6647

As long as your solar connects to the same circuit that is connected to city power, you will have to comply. I do understand the argument that they can't have people randomly connecting generating equipment to the grid (whether or not they feed back to the grid - intentionally or otherwise) but I have feeling that this is about more than that since people have been installing solar for some years now seemingly without causing Armageddon.

In any case, we just need a few more panels, another battery bank and a fully gas oven, and we should be able to cut off completely, but somehow I foresee that they will still have issues. My take is that once we're completely off grid it's absolutely none of their business what we do with our sunshine, but anyhoo.

PS: We effectively pay around R2 per kwh with VAT on prepaid. Guess what we'd apparently get back if we fed our excess back into the grid - R0.60 per kwh. Sounds fair, right?? LOL.

Anyone know the price of a solar powered aircon?

You'll have to make a unit and if a 12000 aircon uses around 800w (I have no clue how much it actually uses,) then the cheapest unit to make would need 4 * 250w panels which means you'll need 4 * 215w microinverters connected together to form a string of 860wh, So around R20k.

T&C's apply:
1. Your solar powered aircon will only work during the day
2. At night you will have to shine a very bright flashlight onto each panel to generate your own sun

The ANC will tax you for the air that you breathe, if they could..
 
seriously, cant we just get convicts to pedal bicycles and generate electricity?

it be cheaper...
and its not like there is a shortage of convicts.

Consensus on small scale wind turbines is "don't bother".
Solar on the other hand is cheap as peanuts. Storage is getting cheaper fast.

Last I checked, Solar + Storage works out cheaper to than Cape Town electricity.

Eg

5KW of Panels = 16 panels x 300W panels (Should generate around 10KW day summer / 30KW / day winter)

16 x 300w Panels @ R1800 x 16 = R28,800
5KW 48v Offgrid inverter (non compliant to CoCT) = R15,000. Add +-10-15k for CoCT listed inverter @30-40k
10KW LFP (Lithium) Batteries R82,000
Mounting / Labour / Install R10,000

Very simplified rough costing -
6000 cycles for battery storage = R1.36 per KW for battery cost. (R82000 / 6000 cycles / 10KW = R1.36)
Solar 0.0029 per KW (28,800 + 15,000 + 10,000 / 5000w / 3650 days (10 years))
Or R1.363 roughly per KW averaged out over 10 years.

Obviously system costs will vary, and lifetime will be longer - panels are rated for 25 years to 80% of original output. Battery rated for 6000 cycles, which is 16 years odd.

15KW is probably closer to where I'd like to be storagewise, or even 20KW, but given pricing, better to go for less, and upgrade 4-5 years later at half the cost*

*Assuming rand levels remain the same.
