There are a few on alieexpess that do 100min
Thats great. will check it out.
wetkit did have a point though. what happens when things are faulty and so on. How would one cover the warranty. Or would everyone just accept that its a chance we take?

Hey akescpt . I must say. I am very surprised at how far i have been able to come on a R13k Budget.
I was able to purchase a 5kva UPS with solar charge controller built in, as well as a "small' bank of 4 x 65AH Deep Cycle Batteries along with LED lighting throughout the house.
.
I usually bring in 10% as spares. Shippping and clearance are equal costs to hardware pretty much for panels, so you can't really ship stuff back - doesn't make sense. You *do* need to do QC on panels if you're buying container loads though.
Last ones I brought in were Cotech Panels. I think I've posted the links on the solar thread before, or they're on my goingsolar site.
I'd ask for DDU pricing.
Also, why 250W, I'd do 300W panels.
Ask for a data sheet - the most important thing for us is looking at temp co-efficient, so the voltage curve / temp is important to check.
Don't forget to bring mounting and cables in also, as the markups here can be horrendous.
See the large solar thread for more info (particularly my posts where I talk about that sort of stuff).

I'd strongly suggest poly panels for here, as mono isn't as good at our higher temperatures.
Essentially my thoughts are - for Europe - Mono, for Africa poly, as we have hot sun, there, its cooler and less sun.

lsheed_cn - I'm also looking at using lipo type batteries. Haven't yet look at sourcing them. Keep us up to date when you bring them in.
Hi all
I'm looking to start small and get my pool pump running of solar. I currently have a 750w pump and a 70000l pool. Has Anyone done this? Should I rather replace the pump with a dc pump? Any advice on what to get and installers in Johannesburg? The lorentz pumps seem to be on a number of local sites - would anyone recommend this?
Hello,
Interesting thread - I've been wanting to go solar a long time - but the local panel prices are disgusting.
I would also be highly interested in a group buy if someone is willing to arrange it and float some numbers etc. out there.
Perhaps also worth discussing what the group buy will include i.e. what everyone is interested in:
1) Solar panels, size and type?
Should we maybe start collecting Kw numbers for each person involved so we can get an idea of how many panels we would be looking at?
From my side I'm purely interested in price per watt i.e. I don't care about efficiency as space is not limited, if it works out that a larger less efficient panel can produce more watts per rand and I need more of them thats perfectly okay with me. Most household solar installs seem to use only a fraction of the roof space available, something I've found in my research on solar is that people seem to be preoccupied with efficiency even if the more efficient panel is actually pushing the price of the system up.
2) Batteries - Will the group buy also include batteries?
Again maybe we should collect numbers on how many batteries each person thinks they would need?
What type of batteries, again from my side I'm not necessarily interested in the most compact batteries ever (something that most battery manufacturers focus on these days) but rather price and how long they will last, if they are a bit bigger/less efficient but cheaper and last much longer thats great in my books - I think its worth considering e.g. less conventional options like NiFe though I don't really care overly much.
3) Inverters - Is it worth including these as well or should everyone just arrange their own locally here?
Personally I would prefer to include inverters as well but I'm not sure what other peoples thoughts are.
I'm keen too I think people are a bit apprehensive to take the lead as its not a small task. Personally I would just buy the inverter here as that has to be SABS approved and has a few regulations around it.
So the ideal for me would be to get panels and batteries that are already sold here but as cheap as possible.
I only need 3-4KW worth of panels though at this stage but if I ask around I could have more people that are interested.
I picked up 2 x 102Ah Ellies batteries at Makro for R1,499 each on Monday. Not sure about quality, but were cheap enough to make me want to try them.105ah deep cycle. Reasonable prices. Where? Please!?
