Lets see, where I live I consume 63kw/24hrs for 280 days of the year.
There is something wrong with the above because the units are wrong.
That must mean 63 kWh/day, or about 1953 kWh per month. Should be
about $195 a month. If that is so, then you use about 2.63 kW of
power on average. At $1 per watt (this must be do-it-yourself?)
that's $2630. However, for $.50 a watt you can replace your hot
water heating, and maybe a good part of your home heating too. A
combined system works best.
So under ideal conditions with tracking arrays I would only need
126kw array
to meet my daily need? (Night time remember!)
But, even with tracking my best guess recovery is not 1kw/m2 but
650w/m2,
goosh that is more than my home cost, when you even consider solar
at $1 a
watt.
Get real, until solar gets to $0.15/W (installed), it is stupid to
consider
it for domestic use unless you live on the Sahara.
My 25 cents look at solar.
