(1) Why add residential battery energy storage systems to solar power generation facilities?

Simply put, residential battery energy storage systems can allow residential users to use the electricity generated by solar power generation facilities when needed, even during periods of low sunlight. It is important to explain to household users that battery energy storage systems optimize their investment in solar power generation facilities and make it possible to use renewable energy electricity almost anytime.

Sunny Yang, Sales Manager of JDSOLAR Ecosystem Solar and Energy Storage Business, said, "To some extent, every residential solar power generation facility needs to be equipped with a battery energy storage system to meet consumer needs. In addition to meeting daily applications, it can also cope with power outages. Therefore, battery energy storage systems are an important protective measure that can ensure the emergency needs of the home in the event of a power outage.

(2) How to store electricity from solar power generation facilities?

Solar power facility developers can explain to customers that solar power facilities use lithium-ion battery energy storage systems to store energy, just like batteries in electric vehicles, which can power for several hours at a time, depending on how much load there is.

Over the years, the number of energy storage systems has grown exponentially, and residential users can now control battery energy storage systems and solar power generation facilities through applications, such as JDSOLAR residential battery energy storage systems. This includes the optional JDSOLAR BESP, which can seamlessly switch from solar power generation facilities to battery energy storage systems for power supply.

Most battery storage systems are user-friendly, and home users can easily program them through a simple and easy-to-use mobile application

(3) How can battery energy storage systems help household users save energy?

When the electricity price of the grid is the most expensive, household users can use battery energy storage systems to store energy. States such as California and Michigan have implemented time-of-use electricity prices, which may extend to other states due to higher electricity costs during peak demand periods in the late afternoon and evening.

It is therefore necessary for developers of solar power generation facilities to explain to household users that during this period, they can use battery energy storage systems to provide electricity, rather than obtaining electricity from the grid during peak power periods, in order to save their electricity bills. For example, in certain regions of California, electricity prices almost double during peak periods, resulting in significant savings in electricity bills.(4) How can residential battery energy storage systems provide assistance in the event of a power outage?

The extreme heatwave in 2023 indicates that the power grid is under increasing pressure, but it also demonstrates the importance of maintaining electricity. The energy stored in battery energy storage systems can provide crucial supply in the event of a power outage.

For example, JDSOLAR's JDSOLAR BESP battery storage system has six intelligent circuit breakers, so home users can specify up to six loads or appliances to maintain operation during power outages. Even if the battery is depleted, the ability to prioritize which loads need to be powered is called load management.

SunnyYang said, "If home users believe that a battery storage system can provide sufficient power and do not have enough power to meet all the loads they use during a power outage, they will feel frustrated. Home users can choose the most important load for them, extend the lifespan of the battery storage system, maintain the power they need, and have a better customer experience.
