Question

excerpt from a consumers guide: get your power from the sun
what is a solar electric or photovoltaic system? photovoltaic (pv) systems
convert sunlight directly to electricity. they work any time the sun is shining,
but more electricity is produced when the sunlight is more intense and
strikes the pv modules directly (as when rays of sunlight are perpendicular to
the pv modules). unlike solar thermal systems for heating water, pv does not
use the suns heat to make electricity. instead, electrons freed by the
interaction of sunlight with semiconductor 1 materials in pv cells are
captured in an electric current.
pv allows you to produce electricity - without noise or air pollution - from a
clean, renewable resource. a pv system never runs out of fuel, and it wont
increase u.s. oil imports. many pv system components are manufactured
right here in the united states. these characteristics could make pv
technologv the u.s. energy source of choice for the 21st century.
the basic building block of pv technology is the solar \cell.\ multiple pv cells
are connected to form a pv \module,\ the smallest pv component sold
commercially. pv modules range in power output from about 10 watts to 300

multiple choice 1 point
which statement gives relevant support for the claim that consumers should
consider all necessary components of pv electricity before buying it?
\in the case of non - grid, or stand - alone, pv systems, batteries can be
purchased to store energy for later use.\
\pv power requires a high initial investment.\
\special appliances that run directly on dc power are available, but
they can be expensive.\
\a solar rebate program and net metering 6 can help make pv more
affordable, but they cant match todays price for utility electricity in
most cases.\

Explanation:

The question asks for a statement that supports the claim that consumers should consider all necessary components of PV electricity before buying it. The text about PV power requiring a high initial investment directly relates to considering components (cost as a component). The other options discuss aspects like rebates (which is an external aid, not a component), special appliances (narrow - scope, not all components), and cost - affordability (vague, not about components).

Answer:

"PV power requires a high initial investment."
