I read in business week magazine about solar plants that use reflected sun
onto a boiler to produce electricity. I think they were 2.5 KW per unit. How
do the efficiencies of phovoltaics compare to these solar boilers?

PV is about 15%. Rule of thumb is about 1KW per sq meter is coming
down on it.

Found the answer to my own question in Business Week magazine, 12 Sep'05
issue.
Solar-thermal dish generator systems operate at 30% while your typical PV
cell operates at less than 10%.

Than what or whose? You provided no context so we know.
