With the outbreak of the COVID-19 pandemic, customers who are under home quarantine or remote work have increased their demand for solar and energy storage deployment. In this regard, some basic knowledge of residential energy storage deployment is introduced to provide some help for installers and residential users.
When it comes to energy storage deployment, it is necessary to have some understanding of residential users' needs and installation work before determining the optimum capacity of residential energy storage system.
The best way to determine its capacity is to break down this process into two steps:
Determine the optimal capacity of the energy storage system after carrying out load analysis.
Analyze the deployment of solar power generation facilities.
If the optimum capacity of the residential energy storage system cannot be determined, energy storage users may incur more costs or fail to meet their user needs. To avoid this situation, installers must first communicate with residential users and find out what their basic load requirements are.
For most residential users, they may initially want to power all the load devices in their home until they understand that it may cost more, and they usually choose to power basic loads. A standard residential energy storage system of 10-20 kWh usually powers its basic loads for up to 12-24 hours.
To achieve this, residential users need to replace energy-consuming devices with energy-saving or smart devices. If they want to provide backup power for air conditioning systems, they need to ensure that the residence takes effective insulation measures and adopts energy-saving air conditioning.
Once the expected values of residential users are determined, the next step is to determine how much backup capacity they may need. If residential users are connected to the grid, a relatively accurate number can be obtained by looking at their previous electricity bills to match their energy consumption.
For off-grid battery-based energy storage solutions, meters can be used to help determine their power requirements and more accurately calculate load energy consumption. Overall, it is better to set higher energy storage capacity, otherwise residential users will be hard to satisfy.
Residential solar power generation and energy storage systems can provide sustainable electricity for residential users during grid failures, saving more on electricity bills and reducing residential carbon footprints.
When deciding where to install residential solar power generation facilities, it is important to consider weather conditions and obstacles such as trees or buildings.
After determining the installation location, the rated capacity of the solar power generation facilities must be matched with the inverter power of the battery-based energy storage system.
Deploying energy storage systems to match solar power generation facilities can theoretically provide a continuous power supply and recover costs by saving on electricity bills.
