1kw per meter is a lot of power.

You have 1300 watts of power in space and 1000 watts of power on the earth's surface. The best solar panel not enhanced is about 17% eff so you end up with .170 kwh. You need to store about 85 kwh per day for a 1600 sq. ft. house that is all alectric.

At $250 per month @ $.10 /kwh is about 2500 kw or 85 kw per day. This has to be done in 6 hours or 14.2 kwh. 14.2/.170 = 83.5 sq. meters.

83.5 x 10.77 = 900 sq. ft. Very doable with battery backup and a inverter. That is 30x30 or 20x45 facing south.

The main thing is cost due to no demand due to folks like you scaring them off and I believe these alternative sources are not adopting the Henry Ford principle. "We will drop the price and make it up in volume". Since a lot of solar panel companies are owned by energy companies that started out in oil, they will not drop the prices to knock them out like connecting rods. But don't worry, in 5 years the oil industry will lose their leverage and they too will go alternate energy due to higher crude costs. The lines on the costs graph haven't crossed yet.
