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

Net metering credits customers for excess generation exported to the grid, typically at the retail rate, which offsets future consumption charges on their utility bill.

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

A bidirectional meter tracks energy flow in both directions — electricity drawn from the utility and electricity sent back — enabling accurate net metering billing.

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

Retail net metering is regulated at the state level by state Public Utility Commissions; FERC only has jurisdiction over wholesale electricity markets and interstate transmission.

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

True-up billing, used in California and other states, settles the customer's net metering credit balance at year-end, with any remaining surplus typically paid at avoided-cost rates.

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

Answer

Net billing compensates exported solar electricity at an avoided-cost or wholesale rate rather than the full retail rate used in traditional net metering, reducing the financial benefit of exporting.
