Enphase using power control to expand legacy NEM systems in California
Many solar homeowners in California looking to expand their PV systems have been stuck, because expanding their systems could mean transitioning from legacy net energy metering (NEM) programs 1.0 and 2.0 to the much less favorable NEM 3.0 tariff program. This week, Enphase Energy announced a solution for expanding these legacy NEM systems in California without penalty via a new power control feature.
These new Enphase power control configurations have been approved by two of the top utilities in California (PG&E and SCE), with SDG&E expected to follow suit soon.
“Enphase’s expansion solution for legacy systems allows us to continue to maximize the value of solar for our customers as their energy needs grow,” said Mike Thompson, CEO of Golden Bear Solar. “These new guidelines and the underlying technology are crucial to support our ability to not just fulfill our role as solar installers, but also be long-term energy advisors to our customers for the lifespan of their systems.”
Legacy NEM expansion systems can help homeowners meet increased energy needs and reduce electricity bills, while providing more business opportunities for solar installers across the state.
“Since homeowners’ energy needs are dynamic, they require energy solutions that can evolve over time,” said Landon Wimmer, CEO of Empower Home. “Enphase’s new configurations for legacy NEM systems activate the highly customizable nature of the Enphase Energy System to maximize energy savings.”
In addition, Solargraf, Enphase’s design and proposal software platform, can help installers design systems that optimize solar and battery capabilities for maximum savings under the new California solar rules.
“As we continue supporting our installers and homeowners in California, it is critical we offer solutions that are designed to maximize value, no matter what policy is in place,” said Mehran Sedigh, senior vice president of sales at Enphase Energy. “Our product suite not only aligns seamlessly with the regulatory changes but also delivers tangible benefits to customers, allowing them to realize the full benefits of renewable energy.”
How does this work? I have NEM 1.0 with old Enphase inverters, and want to double my system size. Will I still be able to export my existing PV energy for full credit?
