DC changeover switch

[Isetech]

This is the reason I haven't put in solar panels for my inverter setup yet. With eThekwini's pricing structure, my utility bill will go up (quite significantly) rather than go down. Seems the safe solution is to put your geyser on solar as this doesn't carry the same prohibitive penalty.

Apparently the size of the inverter will determine your "tax" or "fee" that will be added to your electricity account, not the amount of solar. At this point it is just ramble.

There is a ramble about a few other things that are likely to change in the next 5 years, it is going to put a few DIY installation in a bit of of spot. The green card is certainly not going to cut it.

Trying to sell your property without all the correct documentation and certification for your installation is also going to turn a few systems into lead weights.

I think the introduction of design certification and installation compliance should heave been introduced a long time ago.

We were taking about the same thing this weekend. Do we rather fit an 8KVA unit and additional panels and only one battery, increase the thermostat temp.

The problem is you cant hide the panels, google maps if going to expose all the non registered systems. People think they are going to drive around looking for properties with panels, so they are actually trying to install them out of sight, I not joking.

It is actually a lot easier than that, the average consumption of a house is X amount, if not within a certain range, your electricity bill will be flagged as abnormal especially if you live in a upmarket area, were you can afford a solar system. Then a quick google search under maps and bingo you bust.

The big question is what will the penalty/fine be for not registering your system, the amount they lost in venue?

It is going to be interesting to see where this goes in the future.

One of the reasons I am looking into the Sunsynk unit, it could at least give you a little relief being a bi directional unit. IF you have a backup system you not only going to pay the price, loose.

An average 3 bedroom house uses around 28-30 KWH per day, in area I live, the average bill is around R1500 - 2000 per month electricity only. If you have had a well designed system, replaced all your appliances and fitted LEd lights, bought a gas stove, your bill should drop to around R500. The part that will catch you, is not the drop to R500, it will be the 6 month actual reading compared to the average.

6 months = R12000.00 estimate. Actual after 6 months of the system installation, R3000.00 you dont think a little red flag is going to pop up.

Now imagine the person paying in excess of R10 000 a month, who blows R500k on a system to drastically reduce the bill, do the maths.

Nothing is free in life, someone must always pay. The more you pay the more the free loaders rely on your support

PE has been pretty open about where and how they want to go - Seems like NERSA is going to insist on Time of Use tariff for domestic in SA
Panels and Batteries will play and important role in reducing the cost of electricity

As you can see from the rates pasted below peak times you get hammered on the rate - You just need to move geyser etc out of peak and let the battery supply your evening usage .
The net billing ( dredit amount ) is well below what you pay

I think it is fair as the municipalities need to maintain the network and by using your excess generated they can effectively sell it on without having to buy from Eskom

We still live in the dark ages, with old disk spinning meters. That means they will have to replace all the meters. That would be a nice contract to supply and install new meter, worth a ton of cash, if you get paid.

It is going to be tricky designing the system to be cost effective.

Batteries are going to become an import component in your system.

.

During a discussion on the non registering of PV systems it was brought up that at the start of the drought in PE they used Google with AI software to idenitfy swimpools and dams and match to addresses and accounts - The feeling was that very little work needed to be done to use the same system to search for PV .

Should have mention earlier - PE when you register the pv system with municipality as required by NERSA , the owner gets an invoice of R 6,5K to have a 4 quadrant meter fitted.

Hi Derlyn
I have an old set of lead acid batteries in operation but have bought a new AGM set which I don't want to connect together with the old set. That changeover switch which Isetech has suggested is perfect!

Understood, my brother.
Keep well, daar innie Kaap.
