Nuts & Bolts of Solar Battery Storage System

A solar battery storage system is essentially a device that stores energy for later use and is charged by a linked solar system. Electricity stored in batteries is used in times of power outages, after sunset, or during peak energy demand. It is most frequently found in homes or businesses.

Should You Get A Solar Battery Storage System?


Yes, indeed. The majority of individuals use electricity from the electrical grid to complement solar power. However, domestic solar energy systems with battery storage, often known as solar-plus-storage systems, may provide electricity regardless of the time of day or the weather without the need for backup power from the grid.


Here is why you should use a solar battery storage system:


  • In rare circumstances, you may even be able to profitably sell the energy you are storing back to the grid when prices are higher.


  • Through monitoring tools, a solar-plus-storage system may assist you in more accurately and transparently tracking the energy your system is producing.


  • A solar battery storage systembrings you closer to being off the grid, even though most jurisdictions require residences to be linked to their local utility even if they don’t use any power from the company.

Choose The Right Size Battery

Your power use and the size of the PV system should be taken into account when choosing the size of the solar battery storage system to install. A battery that is installed too small could prevent you from storing as much electricity as possible and from maximizing your self-use, while a battery that is installed too large would prevent you from using all of the storage you have purchased because you would rarely reach the battery’s maximum capacity.


The battery’s performance during the winter, when solar PV power is at its lowest, must also be taken into account. On the market, the smallest lithium battery typically ranges from 1.2kWh to 10kWh. Additionally, you may combine several batteries to build bigger storage systems.


With off-grid storage solutions, the battery and PV array will be matched depending on the total amount of electricity you will draw. If you are unsure, you can upgrade the storage capabilities by installing a battery after the installation.

How Many Years Does A Solar Battery Storage System Last?

A solar battery storage system typically has a lifespan of 5 to 25 years. The most popular kind of solar battery is a lithium-ion battery, which may last up to 15 years. The battery type, installation, depth of discharge, cycle life, environment, and maintenance are some elements that affect how long a solar battery lasts.


One of the most crucial factors to take into account when picking your battery is the anticipated lifespan of your solar battery. Look for historical information on the consistency and effectiveness of a battery.


Get estimates on installation costs and expected savings from various installers before installing a storage system. If you have any questions regarding their calculations, ask them to clarify them for you. You can also consult Yuyang New Energy Co. Ltd. regarding these matters since we are one of the experts in solar battery storage systems in China. Lithium-ion batteries are our main focus.
