Ok so I have been working on a project and right now I am just trying to figure out costs of different systems like energy storage as well as power generation.
I have found that battery's are supposedly about $500 per kilowatt-h or more depending where you get them. What I don't know is are they talking lithium battery's or like SLA battery's? Because I have found that you can get SLA battery's from Alibaba manufactures for about 1 per amp hour at 12 volts, so that would be about $84 per kilowatt-hour.
The other thing is solar panels, I have found solar panels to be about $5 a watt. The thing that I don't get is why am I able to go to like eBay and buy 1 kilowatt worth of solar cells and then make it myself for about $0.30 cents a watt and yet supposedly for like large installations, they still have to pay like $2-3 a watt?
