    Default Complete System - Home Use - Busy doing specs now.

    Biting the bullet, going balls to the wall on this.

    First item: Convert normal geyser to solar geyser. Order a kit from Geyserwise. Consiststs of tubes and panel, controller, 12v pump and some other fittings and gubbins. Hook up to existing high pressure geyser and Bob's your Auntie, solar hot water with geyser timer and Eskom backup.

    This geyser for our laundry and the biggest power eater we have.

    The conversion kit costs R10k. Payback / amortization will be 12 months here.

    Second item: Full 3 phase system for our main house. Will be hybrid grid tie. Appears as if we can get 16 panels on the roof, 5kw inverter, Lithium Ion batteries. Also going for a wind turbine, and just because we have one, a generator tie in.

    Wind turbine does not hook up to inverter, but rather has its own controller and charges the batteries directly.
    Generator and panels hook up to inverter.

    Inverter / controller will run on Eskom and what we generate - floats between the two continually. Apparently this is the way to go so when you start a fridge or aicon, you do not have starting up issues as you just draw more from Eskom for a short while.

    Most amazing app on your phone - shows you how much total power you using right now, for the day, for the month etc. Shows how much power you generating right now, for the day for the month etc. Works out the costs etc for you.
    We pay R2.03 per Kilowatt Hour here.

    At night in winter we have no wind, but we do not draw much power at night, just electric blankets. But in summer we have to run the aircon's all night, and we have big summer winds - so the plan is for the wind turbine to make us power while the sun sleeps.

    Expect this to cost approx R150k. Payback or amortization appears to be 5 years.

    Just doing a pure financial planning model on this, this makes more return than the JSE.

    We will need to adjust certain things we do and the way we live slightly, but will be worth it.

    On the hunt for an insulated gas kettle. You can finally buy insulated electric kettles in the UK, about R2000. Just a kettle built like a flask, so once boiled, water stays hot far longer than normal kettle. For your second cup, kettle boils in seconds. Now looking for one for our gas stove.

    Anybody got any really good points and tips, please gooi. Please remember all the above is a very simplified view, has to be so I can understand it. Cheers.

    Make sure your plumber covers ALL the pipes to/from the tubes well with insulation. My system has been marginal in winter and a trip into the roof revealed a few meters totally uncovered.....
    Also, fit anti-siphon loops to stop the heat running up the lines, and shut-off valves either side of the various systems so you can isolate for repairs and maintenance if needed as well as a valve to vent pressure off if you do shut the tubes off... I shut my plates off for about 15 minutes to do something on the roof and the pressure build up cracked the circulation pump body.
    Cheers,
    John
