If electricity is consumed at 154 Watts (for an average person), then 154 Watts of PV panels will not be able to meet this demand, since the sun is not always out. Given an average capacity factor of PV to be ~25%, you will need about 4 times the average demand to meet the installed PV capacity. Thus, you will need 600-6000 USD per person for PV panels to meet the demand. Also, you need a balance of systems (BOS) to convert the DC power of PV to AC and put it on the grid. The average BOS for large scale PV is another $1/Watt, and up to $2.5/Watt for residential. This will push up installed cost by another factor of two to three, to about 1500-15000 USD/person to meet demand. Once you have that excess PV installed, storage becomes a necessity.
