Are you curious about Net Metering 2.0? Do you know what’s changed under the new policies? Are you wondering how the 2.0 program will affect you?
If so, you’re not alone.
According to EnergySage, Californians installed upward of 13,241 megawatts of solar in 2015, nearly five times the amount of the second-place state — Arizona.
Unfortunately, the Net Metering 2.0 structure is far from clear. If you’ve ever wondered how the net metering policy works, or what to make of Net Metering 2.0, here’s a simple breakdown.
The Net Metering 2.0 program allows California citizens to receive credits on their utility bills for any excess electricity produced by their solar panels, as long as their systems are under 1,000 kilowatts. As the 2.0 would indicate, this net metering policy is an upgrade to the original.
While the original policy dictated that California residents would get a one kilowatt-hour bill credit for every kilowatt-hour of electricity their residential solar systems put back into the grid, Net Metering 2.0 introduces some slight changes.
Although NEM 2.0 maintains the kWh credit functionality, it outlaws some fixed charges levied against residential customers, including charges to access the grid as well as standby and demand charges. The 2.0 program also lifts the cap on how much of the utility’s grid could be solar power (formerly 5 percent).
The current Net Metering 2.0 program is slated to run until 2019. The pros and cons of the current NEM 2.0 currently ruling can be found on Sage Renew’s site.
If you’re a California resident with a solar power system, here are five things we believe you should know about the current Net Metering system:
As long as your system is under 1,000 kilowatts, you qualify for the 2.0 energy buyback plan. With that in mind, you’ll want to slightly oversize your system so that you’re putting as much energy back into the grid as possible, without exceeding your yearly consumption by much more than 5-10%. Sandbar Solar has more than 13 years of experience in the solar industry and can help you figure out how large your system can go without violating Net Metering 2.0 guidelines.
What’s more, NEM 2.0 customers must pay non-bypassable charges (NBCs) on the energy they use. These charges help utility groups save some money on decommissioning and can reach $0.02 per kWh of power.
Since the installment of Net Metering 2.0, California participants are subject to time-of-use (TOU) rates. These rates make power more expensive during peak hours (usually between 3-8 pm) and less expensive during the remaining off-peak hours.
Under Net Metering 2.0, residents will receive more money for electricity they create during peak hours and less for any power sent back to the grid during off-peak hours.
This brings us to the next point.
While it’s a common notion that placing panels on the west side of your home will maximize your energy credits, the truth is that solar panels function admirably on ambient light, so placing them wherever they’ll get the most exposure on your roof (as south-facing as possible, and NOT necessarily the west side) is the smartest move.
While utility companies continue to alter their rates according to a vague set of protocols and circumstances, solar should be predictable. Unfortunately, NEM 2.0 uses metrics such as time-of-use charges and other fees to make solar output hard for consumers to predict.
This can make it difficult for homeowners to fully understand the economic impact or benefit of their solar system, and make a smart choice about whether or not to install one. However, by keeping in mind points 1 and 3 above, you will be sure to maximize the benefits.
Since its introduction, NEM 2.0 has been met with some uncertainty. In addition to offering time-of-use rates and forcing optimized, specific systems, NEM 2.0 may complicate solar energy for residents.
