Question 1

Net metering allows a residential solar PV customer to:

Accepted Answer

Receive a bill credit for excess electricity exported to the grid, applied against electricity consumed from the grid

Answer

Receive wholesale electricity rates for all power generated on-site

Answer

Sell electricity directly to neighboring customers at market rates

Answer

Avoid all utility fixed charges and demand fees

Question 2

A bidirectional meter used in a net metering solar installation measures:

Accepted Answer

Both electricity imported from and electricity exported to the utility grid

Answer

Only electricity consumed from the utility grid

Answer

Only electricity exported from the PV system to the grid

Answer

Real-time DC output from the solar panels

Question 3

Which regulatory body has primary jurisdiction over retail net metering policies for residential solar customers?

Accepted Answer

State Public Utility Commissions (PUCs)

Answer

FERC (Federal Energy Regulatory Commission)

Answer

EPA (Environmental Protection Agency)

Answer

Question 4

'True-up' billing in a net metering arrangement refers to:

Accepted Answer

An annual settlement where accumulated net metering credits are reconciled against total annual electricity consumption

Answer

Correcting errors found in monthly electricity invoices

Answer

Upgrading a standard meter to bidirectional net metering capability

Answer

Connecting the final electrical wire from the inverter to the service panel

Question 5

What distinguishes 'net billing' from traditional net metering?

Accepted Answer

Net billing compensates exported solar electricity at a lower avoided-cost or wholesale rate rather than the full retail rate

Net billing applies two separate utility bills per month

Answer

Net billing charges customers for both importing and exporting electricity

Answer

Net billing requires a separate dedicated export meter

Question 6

A solar customer's bill shows 800 kWh consumed from the grid and 1,000 kWh exported to the grid during the month. Under net metering at $0.12/kWh retail rate, what is their net position before fixed charges?

Accepted Answer

A credit of $24.00

Answer

A charge of $24.00

Answer

A charge of $96.00

Answer

A zero balance (net zero)

Under many state net metering programs, what typically happens to excess annual generation credits at the annual true-up date?

Accepted Answer

They expire or are paid out at a reduced avoided-cost rate rather than the full retail rate

Answer

They roll over indefinitely at full retail value into future years

Answer

They are donated automatically to low-income energy assistance programs

Answer

They are applied as a credit toward grid interconnection fees
