Question 1

Which US federal incentive allows renewable energy project owners to deduct a percentage of system cost from federal taxes in the year the system is placed in service?

Accepted Answer

Investment Tax Credit (ITC)

Answer

The Investment Tax Credit (ITC) allows project owners to deduct a percentage of eligible renewable energy system costs directly from their federal tax liability.

Question 2

What is 'net metering' in residential solar PV systems?

Accepted Answer

Crediting customers for excess electricity exported to the grid

Answer

Net metering credits residential solar owners for surplus electricity sent to the grid, which offsets their future electricity bills.

Question 3

What is the main advantage of bifacial solar panels over monofacial panels?

Accepted Answer

They capture reflected light on the rear surface for higher yield

Answer

Bifacial panels generate additional electricity by absorbing albedo (reflected) light on their rear surface, increasing total energy yield.

Question 4

What is a 'virtual power plant' (VPP) in the context of distributed renewable energy?

Accepted Answer

A cloud-based aggregation of distributed generators and storage units controlled as a single entity

Answer

A VPP aggregates distributed energy resources—solar, storage, demand response—and controls them collectively to provide grid services like a conventional power plant.

Question 5

Which wave energy converter (WEC) design uses the relative motion between a floating body and a fixed or slowly moving reference to generate electricity?

Accepted Answer

Point absorber buoy

Answer

Point absorber buoys harness the heave and surge motion of ocean waves relative to a fixed mooring or seabed anchor to drive a linear or rotary generator.
