Some considerations/questions:

Sunlight puts out 60 w/sq. ft. when the sun is shining.
At 10% efficient, you'd need 100 sq. ft. of photovoltaic cells to provide 600 w while the sun is shining.
Assume lead acid batteries are 70% efficient.

Will the array track the sun?
The appliances run 16 hrs/day?
How many watt-hours/month does your house currently use?

i just want to run a Fan and Tube Light.... that's it
