Four typical systems of photovoltaic + energy storage

solar energy system

With the implementation of energy storage policies and energy storage incentives in China, photovoltaic practitioners have gradually begun to talk about Photovoltaic energy storage + system from talking about photovoltaic + systems. This article introduces several standard Photovoltaic storage + systems.

1. Photovoltaic energy storage + charging pile

With the application of photovoltaic energy storage systems and the popularity of electric vehicles, the combination of the two has received extensive attention.

① Household light storage + charging pile

       Household light storage

Working logic:PV is given priority to household loads. If there is any remaining, the car will be charged when connected to an electric vehicle, and the energy storage battery will be charged when it is not connected to the vehicle. After fully charged, it can be sold to the power grid. If it is not allowed to sell electricity, it can also be set on the mobile app not to sell electricity. At night, the energy storage battery is discharged for home load use. During a power outage, photovoltaics and batteries only supply off-grid loads.

② Photovoltaic carport

The public photovoltaic energy storage carport satisfies the properties of the carport for sheltering from wind and rain and improves the spontaneous self-use rate of photovoltaics. When there is no vehicle charging, the photovoltaic power generation is stored in the battery, and the battery is discharged to charge the electric vehicle when needed.

2. Photovoltaic energy storage + BIPV

The combination of an optical storage system and BIPV can not only maintain the beauty and safety of the building, but also deeply integrate into green power.


The roof area of the project is 108 square meters. A total of 41 pieces of sun tile products are installed on the north and south slopes. The photovoltaic utilization area is 3.7kW

 photovoltaic system; ——The project adopts GoodWe's overall power solution, the system is self-generated and used, and is integrated into the original power distribution system.

3. Photovoltaic storage + community photovoltaic

Community photovoltaics are currently widely used overseas. The following case is the community photovoltaic storage project of GoodWe in Alabama, USA.

The project involved 62 households and installed a total of 800kWp photovoltaics and 1.5MWh batteries. Each household's optical storage system is given priority for self-use, the surplus electricity is shared (sold), and the insufficient part is taken from the DC bus. The system is uniformly dispatched by the EMS system.

4. Photovoltaic storage + county-wide promotion

Photovoltaic storage + county-wide promotion

The county-wide promotion in full swing is not just a model of photovoltaic power sales. More and more provinces require energy storage to be added to the county-wide promotion. For example, in bus terminals, schools, government offices and other scenarios with many roofs and high power consumption.

The following case shows the optical storage solution designed for the bus terminal. The system includes photovoltaic modules, grid-connected inverters, AC-coupled inverters, batteries, EMS systems, etc., which can effectively reduce grid electricity consumption, sharpen the load, and ensure electricity safety.

The working logic is to supply daytime bus charging and office power for the photovoltaic system. The remaining part of the battery is charged, and the insufficient part is supplemented by the grid. Can support electric bus fast charging. At night, the battery is charged to the bus (slow charge), and the insufficient part of the grid is replenished. EMS uniformly monitors the status of charging piles, optical storage systems, and power grids, and uniformly adjusts the power consumption in combination with the bus travel schedule. In exceptional cases, ATS switches to an off-grid power supply to ensure the regular power supply of site control systems and safety facilities.

In addition to the above optical storage + system, there are also application scenarios such as optical storage + microgrid, optical storage + DC building, and optical storage + sun room. Solar storage + system may become a new growth point of domestic photovoltaics. Let us wait and see.
