Glander - RE: How much did it cost?
Well, that's where my system 'outshines' the other option that is being promoted today - that is adding 18 or more solar panels to the roof and putting electricity back on to the grid.
A fella I know had solar panels put on his home. He spent about $30,000 to do this. He still does not have any electricity if/when the power goes out, as there is no battery storage.
My system? Well, when I bought my first 68-watt solar panel, I think that I spent over $200 for it. The second one, I spent $175. I got a notice via e-mail that the price has been dropped to $100.
Then there is the battery. I spent about $200 for my latest 75-Ah SLA, but you don't need that much juice. You could probably get by with 1/2 that, and pay about 1/2, or about $100.
Then there are the small bits like the charge controller $25.00, the Low-Voltage Disconnect (LVD)/ InfraRed (IR) Switch about $75.00, the LED lighting systems at about $50 - $100 each.
So, I guess, with careful shopping you could spend around $500-$600.
Payback on this investment? I figure in about 18 months... maybe 2 years tops.
Not worth it to some, but it is to me. Both me and my wife just sit and smile when we turn on our LED lights that are powered by the sun (in a round about way).
Oh. And for those that may say that the SLA batteries will end up in a landfill someday... I disagree. They recycle those sorts of things these days. Plus, I have one SLA that I started with about 10 years ago that is still working to this day. It may not be at 100% capacity like it was when I first got it, but I still use it for demos and such, and it has plenty of power left in it.
Most of what I am doing I will be putting up online and offering at retail prices for those that may want to just purchase something that works, rather than experiment. I'm still working on my web site.
