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
12 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 Replyi would imagine living somewhere tropical might be even better
2 0 ReplyOver the past year I'm averaging about 1.1 kwh per day per square meter on my system.

But if the offer's shunned, you might as well be installing solar panels on the sun
