California NEM 3.0 will take effect on April 15, which would majorly impact the solar market. The new scheme slashed the net metering export rate, which resulted in a 75% reduction in credits for excess energy sent to the grid. Solar customers need to consider how to preserve the value of their solar energy systems.

Net metering is the basis for saving money with solar, which allows excess energy to be sent back to the grid in exchange for a credit on your next utility bill. Electric bills are cut significantly from owning your own electricity to the utility company.

In response to this change, adding energy storage batteries to solar systems has become a new option. The original excess power can be stored in the battery as a household backup power for self-generation and self-use.

In addition to net metering changes, time-of-use energy programs are also promoting the addition of solar cells. The new timeshare plans have higher rates during peak hours and lower rates during off-peak hours. If you're strategic about your electricity usage, you can reduce your home energy costs by using stored solar power to avoid grid power during peak hours and use cheaper power to charge your electric car or run appliances like your dishwasher during off-peak hours.

The new regulations have boosted the development of residential energy storage systems in California. EP Cube is a residential energy storage system brand that entered the United States last year. Its installer revealed that it has received more orders than expected in just a few months. They need to work harder to cope with the growth of the business.

"On the one hand, customers who buy solar panels are now more inclined to solar systems paired with batteries. On the other hand, our products are in line with the development trend of energy storage batteries in design and functional technology, such as customizable capacity, easy installation, support With features such as the connection of old and new photovoltaic systems and EV chargers, customers can easily and quickly upgrade their solar systems." Ryan, head of the EP Cube marketing, said.

While home storage batteries add to the overall cost of a solar system, the payback time for solar systems under NEM 3.0 and time-of-use rates may be more optimistic than expected given the subsidies for clean energy.
