Question

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 technology 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. modules range in power output from about 10 watts to 300 watts. a pv system connected or \tied\ to the utility grid? has these components:

• one or more pv modules, which are connected to an inverter
• the inverter, which converts the systems direct - current (dc) electricity to alternating current (ac)
• batteries (optional) to provide energy storage or backup power in case

multiple choice 1 point
how does the author support his claim that the pv systems connects to the utility grid?
by providing examples of solar resource components
by explaining how certain appliances work
by discussing how energy connections work simultaneously
by clarifying how the optional use of batteries can be beneficial

Explanation:

The text describes the components of a PV system (PV modules, inverter, batteries). When asking how the author supports the claim that PV systems connect to the utility grid, providing examples of components (like PV modules connected to form a module, etc.) is a way of support. For example, it lists "One or more PV modules...connected to an inverter...Batteries (optional)" etc., which are examples of components that make up the PV system and by extension show how it connects (as these components are part of the system that can be connected, e.g., modules are part of the system that can be part of a grid - connected setup).

Answer:

By providing examples of solar resource components
