The intermittent nature of photovoltaic power generation has always been a challenge to its large-scale application, and the addition of energy storage technology perfectly solves this problem, forming a stable and efficient clean energy system.

1. Solve the shortcomings of photovoltaic power generation and improve energy reliability

Photovoltaic power generation relies on sunlight and cannot supply power at night and on rainy days. Energy storage systems (such as lithium batteries) can store excess power during the day and release it when needed, achieving 24-hour stable power supply and reducing dependence on the power grid.

2. Home application: power saving + emergency + income
After the family installs "photovoltaic + energy storage", it generates electricity for self-use during the day, stores the surplus electricity, and uses it at night, which can reduce electricity bills by more than 50%. In the event of a power outage, the energy storage system can provide emergency power supply. Some areas also support the sale of surplus electricity to increase income.

3. Power grid support: peak-to-valley shifting and stable operation
The energy storage system can smooth out the fluctuations of photovoltaic power generation, discharge during peak power consumption, and relieve the pressure on the power grid. In the future, distributed "photovoltaic + energy storage" can form a virtual power plant and participate in power market transactions.

4. Future trends: cost reduction, technology upgrade
With the decline in lithium battery costs and the development of new technologies (such as sodium-ion batteries and hydrogen energy storage), the economic efficiency of "photovoltaic + energy storage" will continue to improve and become the preferred energy solution for families and businesses.

The combination of photovoltaics and energy storage is driving the energy system towards a clean, efficient and intelligent direction, allowing everyone to become a participant and beneficiary of energy.
