Argh I hate how they never show installation costs upfront...
39 0 ReplyPeople think the cost of the panel is the most expensive, but it's actually the 151 million km copper cable
33 0 ReplyWhy can't we just wirelessly transmit the power, maybe have it hit a collection device that can harness about 4 kwh/m^2/day
16 0 ReplyCopper wouldn't cut it, too much resistance. You need a superconductor... only problem is how to keep it cold enough at below 1000C.

Is it true that you can get 4kwh per day per square meter? My average electricity consumption is ~15kwh/day, so if I can potentially offset most of my grid usage with just 4 square meters of solar panel, that seems very attractive. I live in a tropical country btw.
5 0 ReplyNo, 4kwh is about the daily amount of sun hitting 1 square meter. Solar panels can capture about 20% of that
13 0 ReplyEach of my panels has a theoretical capacity of 390 Watts per hour. So 4kwh in a day seems very feasible. My panels are certainly not the cutting edge of technology!
3 0 ReplyYour 390W is if the sun is in the zenith and hitting your panel at right angle. Also, are you sure your panel is 1m^2?

Over the past year I'm averaging about 1.1 kwh per day per square meter on my system.

And if you follow, there may be a tomorrow
But if the offer's shunned, you might as well be installing solar panels on the sun
