    is this something possible or too expensive to be worth the time and money?

    Ive seen many household things powered by solar power... googled a few sites on this also, some kits are VERY expensive.

    But having a reef operating fully on solar power would mean that you saving in the long term and also saved from power cuts

    the big problem is the cost of batteries. They do not last forever and need to be replaced.

    so your night time and heavy overcast days could be an issue. Options like sky lights can reduce your lightning needs. But some guys stays in complexes or places where skylights is just not the answer.

    If solar panels excess energy could be pumped back into the grid, with your meter running backwards. Then at night you use your "saved / banked" power, Yes then it could be worthwhile. As the need for batteries are removed - except for one to run the return pump when needed.

    Hi Zaxx

    with carefull planning and the correct equipment there is no reason why your reef tank should be pricey to run.

    I am currently running a 850 litre reef system 1500 x 1000 x 500 D

    Full SPS clams nennies etc

    Total watts for the entire setup in summer is plus minus 500 watts

    Its way too expensive to run our electricity hungry tanks. You will have to spend loads on the solar setup and then even more loads to get all your equipment replaces with low wattage ones. And then as Riaan said there is the replacement of batteries every 2 - 3 years. And they are R1000 a pop for the cheapest deep cycle battery. The high capacity ones are up to R5000+ a battery.

    Does anyone know if the grid tie-in systems work in South Africa?
    I know eskom dont pay you for the electricity, but surely if you put power back into the system it would reduce the total monthly cost.

    Also no need for deep cycle batteries!

    The policy around grid-tie systems is currently being developed. My dad runs a renewable energy business and has been actively pushing the policy. Its not coming tomorrow, but I believe its a lot closer than we think...

    Please, the day this is past, let us know.

    Then a lot of people would invest in solar panels, eventually helping to bring the cost down.

    Mariusmeyer and RiaanP are right about the batteries on these things.
    We have a lovely UPS that cost 55k at the office for backup to run the place when load shedding happens and it only runs lights and some PC's (about 3) for about 4 hours with brand new batteries.
    We have had this thing for 2.5 years and it's costing us another 15k (now) to have it fixed as the batteries are busted and on top of that the ppl that come to install the batteries also want more money. :(
    I am thinking that losing the work while the power is out is cheaper than maintaining this thing.

    This is obviously not the case with 10k in live stock you might have with added sentiment but I'd say go for another option. Those batteries are ridiculous and they are not eco friendly in anyway whatsoever. I use them as doorstops now to try keep them out of the planets eco systems. but I don't have enough doors at the office or at home so eventually I will have to start building a house with them or something. And if you think you can wait another month before replacing them you are mistaken the start bleeding acid all over the place and this burns the case it's in and cause power issues which may or may not lead to replacing electronics.

    lol
    And I think it's pretty obvious that these batteries have made my life hell.

    If you generate too much energy during the day, and pump the excess into the grid. Your meter running backwards. Then at night, you use your "deposited" energy. Ideal will be to come out at zero used for the month.

    During the day, when you are at work, only other appliance that needs power (more than 200W) is your fridge.

    I have been thinking about the same concept and ordered solar panels plus inverters and stuff direct from China.
    Lets see what the stuff looks like when it arrives.....

    This is correct but i still not sure it works on our meters

    Nope, our meters are not clever enough for that.
    You need a special meter for that.
    And no, they don't give you credit if you are on a pay as you.....

    Thats the normal capacity ones (105AH).
    By High capacity I am talking up the 1000 (thousand) AH. You get some serious batteries out there.

    Holly cr@p.
    1000Ah batteries.
    Do you need a trailer to cart them around?

    for lighting these maybe the answer need only installation just not sure on the expense of them

    but they bring sunlight indoors via fibre optics no electricity no batteries!
