All that will do is swap your electricity bill for your petrol bill. Which one is cheaper per kW of energy?

The alternator doesnt put a significant load on the engine,.. not as an aircon pump does, so basically its free energy. Only the little extra weight you carry that can increase fuel consumption.

The energy to charge the battery must come from somewhere. There is no such thing as free energy. And last time I looked, the fuel cost for a generator was much more than the electricity cost for the same load.

Well, if you want to get technical..only let the battery charge if you apply the brakes.

Being a developer (smaltime) I started redesigning the geyser setup in conjunction with the plumber. If a house needs 2 geysers they are coupled in serie. The one geyser is switched of in times of low usage. In times of higher usage the first geyser is only used as an pre heater for the second unit. If the client wants an solar unit (only the panels ) is coupled to the 1st geysers inflow. A controller unit is pre installed to the second unit that regulates the power up times. The plumber told me afterwards that in retrospect he will implement this to most new houses. Thing is the architects, city councils, eskom doesnt make an concerted effort to educate in this regard.

The answer for me lies in the hands of the regulator. Alow people, houshold to sell any electricity they can produce into the grid at wholsale prices and buy shortfalls at retail prices that way I dont need a solar heater or a whatever, I simply need a two way metre, and a solar pannel or 3. Think what an effect this whould have on the unemployed oke in the township who gets a solar pannel as a grant, he can earn a living from his shack roof..

This is exactly what I have, but there has been zero optimisation. I assume this means that the first geyser (solar) should have no power switched on - except possibly in cases of extreme hot water requirements or cloudy days. The second geyser (in turn) should be heated using a timer - really just to keep the prefeed water at optimum temp. This would probably be tweaked with experience.

Ja, swaar...and soon we will be reading about solar panel hijackings...

I'm investigating buying a property between Knysna and Uniondale - no Eskom so need alternative power. In that area apparently the only crime which occurs is theft of Solar Panels if you leave them unattended for too long! But no panel highjackings yet...

Up till just after the first "free election " in 1994 Lydenburg produced its own electricity from hydro turbines on the Dorps River and as a result the whole town 5000 residents payed almost nothing for for electricity.Of course all was stopped as the new south africa decided this was a colonial method.Funnily the muncipality has maintaine d the equipment in good working order.Unfortumnately the same can not said of the muncilpality,where the major was forced to resign eventually ,but only after her house was burnt down!We dont even receive muncipal bills anymore.i pay what i think i should.The equipment can feed into the local escom grid and has the capacity to supply 15,000 households.

Gareth. The main benefit of the configuration is that the second geyser doesnt have to run except when theres huge demands.
