How To Choose A Home Solar Energy Storage System

At present, many homeowners are shifting towards sustainable energy solutions, which is why the demand for solar power solutions is increasing. As solar panels can only generate electricity when sunlight is available, the need for reliable solar energy storage is high. Let’s get to know more about home solar energy storage systems, how they work, their benefits, and many more.

How Do Solar Energy Storage Systems Work For Your Home?

Solar energy storage systems or solar batteries store excess solar energy produced during the day that can be used later at night or during power cuts. There are different types of solar energy storage systems, such as lithium-ion batteries, lead-acid batteries, flow batteries, and nickel-cadmium batteries. The home battery backup system units contain inverters/chargers, charge controllers, deep-cycle batteries, etc. 
The residential energy storage systems convert direct current electricity from solar panels into alternating current electricity that can be used in homes. The AC electricity is then accumulated in the battery until it is required. When there is a demand for the stored electricity, it is transformed back into DC electricity and sent to the home’s appliances.

Benefits of Solar Energy Storage Systems for Homes

From grid independence to cost savings, there are plenty of advantages of residential energy storage solutions. The primary benefits of whole home battery backup systems are listed below: 

Environmental Friendly

By producing and storing their own solar energy, homeowners can decrease their carbon footprint and contribute towards a sustainable future. Also, by storing solar energy in the home solar backup systems, it is possible to reduce the usage of traditional energy sources like coal and natural gas, which emit significant amounts of greenhouse gas emissions.

Backup Power

Residential battery energy storage system units can store excess solar energy produced during the night. This stored energy can be used to power the home during power outages or other emergencies. Solar batteries make sure that residences have a constant power supply. 

Low Energy Bills

Solar panel battery storage systems can help homeowners save a significant amount of money on their electricity bills by decreasing their dependence on grid electricity. This also contributes towards long-term energy savings. 

Better Grid Stability

Solar battery backup for home systems can help stabilize the grid by offering a reliable power source during periods of peak demand. This ensures improved grid stability. 

Eligible For Tax Credits And Incentives

There are plenty of tax credits and incentives that are available for residential owners who want to install whole home battery backup systems. People can take advantage of these incentives to save money on solar energy system installation. 

Quiet Operation

In general, battery storage for solar power systems operates relatively quieter compared to traditional generators. In addition, they do not produce noise pollution. 

High Property Value: Residences that have solar system with battery storage units have more value compared to homes without them. This is because solar energy systems offer significant savings on energy bills and boost the home’s energy efficiency.

Tips To Choose The Right Residential Energy Storage System

There are some factors that one should consider when choosing a residential battery energy storage system. They are mentioned below: 

Determine Energy Needs 

First of all, it is vital to figure out the total amount of energy that is used on a day-to-day basis. To determine daily and peak energy consumption, it is best to assess the electricity usage patterns and recognize the times when the power is used mostly. In addition to that, it is also recommended to consider future energy needs like planning for an electric vehicle, etc. 

Type Of Battery 

There are different types of batteries utilized for residential energy storage, such as lead-acid, lithium-ion, and flow batteries. Nickel-cadmium batteries are also a type of solar battery, but they are mainly used for commercial solar battery storage

Lead-acid batteries are the most common type of residential battery energy storage system, but their lifespan is short. Lithium-ion batteries offer longer lifespans and deeper discharge capabilities, but they are a little expensive. Flow batteries are a newer technology with a long lifespan and deep discharges, but they are still under development.

Battery Capacity 

The capacity of solar batteries is calculated in kilowatt-hours (kWh), which is the amount of energy that the battery can safely store. Depending on the household’s energy needs, it is best to choose a battery. For instance, if the electricity needs are high, one needs to select a storage system with a higher battery capacity. 

Depth of discharge (DOD) 

Depth of discharge is the percentage of a battery’s capacity that can be utilized before it has to be recharged. If a solar battery has 50% DOD, then it can be discharged to half of its ability, and then it needs to be recharged. The DOD of a solar battery is based on the type of battery and how it is utilized.

Battery Efficiency 

As for battery efficiency, it is the total amount of energy that is stored in the battery that can be utilized later. It is best to buy solar batteries that have higher efficiency so they can be used to power numerous appliances for a longer duration. 

Battery Life Cycle 

The cycle life of a battery is the total times it can be charged and discharged before it begins to lose capacity. Solar batteries with a higher cycle life can be used for a long time before they need to be replaced. 


In general, the average price of storage batteries for solar panels ranges from $20,000 to $35,000 or more. This is because the cost of solar batteries is based on the size of the battery, type of battery, etc. Apart from the initial buying cost, one needs to consider the installation and maintenance costs as well. 


One of the overlooked factors when buying home solar storage systems is compatibility. Make sure that the solar batteries are compatible with the inverter and solar panels.
