Solar Battery Storage

Guide 101: Everything About Solar Battery Storage

Most Australian homeowners have already adopted clean-sourced energy – solar, as a way to save thousands on their utility bills and reduce individual CO2 footprint. Solar panels are commonly found upon the rooftops of Australian homes, and homeowners are getting used to living an off-grid life. The popularity of solar power in Australia is driving down prices, making the solar industry one of the fastest-growing and job opportunity producing sectors. Homeowners are now planning to upgrade their already installed solar system by adding solar battery storage

Solar battery systems offer homeowners the advantage of storing excess energy produced by the PV panels and using it during evenings or blackouts. Such solar power storage units can power homes even after the sun goes down and protect the value of the energy-generating in-house. Solar batteries are the simplest way to make the best of solar power further.

What Is a Solar Battery?

A solar battery is an energy storage unit that stores power generated by solar PV panels. Homeowners can store their excess energy produced through solar batteries and use it when the sun goes down or during power cuts. Rather than sending the excess energy generated to the grid, you can consider using it for daily power consumption. 

Having a solar battery can also help you save money on your utility bill by using power generated from the solar system rather than relying on the electricity grid. Such energy storage units allow you to take advantage of the time of use feed-in tariffs and save maximum power. 

Households can export excess energy in peak demand periods to enjoy the benefit of a high feed-in tariff.

How Solar Battery Storage Stores Solar Energy?

Solar energy stored in solar batteries is typically used during the evening or during power cuts. Here’s how solar energy is stored in solar batteries:

  • Solar PV panels absorb sunlight and generate electricity
  • The direct current (DC) electricity produced flows through an inverter to generate alternating current (AC) electricity
  • The AC electricity is used to power home appliances
  • Excess electricity not used by home appliances charges solar batteries
  • After sunlight hours, appliances use stored solar energy produced by the battery

Types of Solar Batteries

There are four common types of solar batteries:

1. Lithium-Ion Solar Battery

Lithium-ion batteries are a common and popular type of solar battery available in the market. Such battery types are durable and often last for ten years. However, they can degrade to about 60% storage capacity over time. Lithium-ion batteries are non-recyclable and harmful to the environment.

If you are looking for a battery option that can reduce the negative environmental impact and work optimally, choose our SonnenBatterie solution. Each SonnenBatterie solution is cobalt-free and has a 10-year warranty plan.

2. Flow Battery

As the name suggests, flow batteries use flowing electrolytes (bromide or zinc) to store energy and later release it for daily use. They can operate well in high temperatures, be discharged to 100%, and don’t lose capacity quickly. 

However, flow batteries can be quite expensive compared to other batteries and have a shorter life than lithium-ion batteries. Another downside is they don’t operate well in the cold temperature.

3. Nickel-Iron

Nickel-Iron batteries are extremely durable, have a high energy density, and can be completely discharged. However, they can be expensive compared to other battery types, have a shorter lifespan, and are extremely slow to charge.

4. Lead Acid

If you are looking for an affordable battery option, opt for lead-acid batteries. They are relatively cheaper, and most recycling companies can recycle such batteries. The downside of lead-acid batteries is a shorter life span and low energy efficiency.

4 Benefits of Solar Power Battery Storage For Your Home

Solar is an abundant, infinite source of energy that offers a myriad of economical and financial benefits for any residential and commercial property owners. 

People prefer to go solar as it helps them enhance their surrounding environment and reduce individual energy costs. Using solar panels is the best way to upgrade your property’s energy efficiency level at a cost-effective rate. 

Solar Power Battery Storage For Your Home

The free renewable source of energy also reduces individual carbon footprint and improves property value. 

If you are impressed with such exceptional benefits of installing solar panels at your home, how about solar batteries? 

Investing in solar battery storage can offer you blackout protection and reduce costly electricity bills. Installing solar batteries with solar panels could be one of the smartest investments for your home.

4 Benefits of Using Solar Battery Storage

1. Use When Needed

The solar panel captures the sunlight and transforms it into electricity. This means that to produce and generate electricity, solar panels will need a sufficient amount of sunlight. These solar photovoltaic (PV) panels can capture and store solar energy during the daytime. 

Clouds and shade may be the probable reason for the output reduction of your solar panels. The output reduction of the solar system means drawing off the grid electricity, which can take a toll on your utility bill. 

Solar batteries can store the excess energy produced which can be used during extreme weather conditions or nighttime. All this without having to draw off the grid electricity!


2. Reduce Electrical Bills

With the solar system, you can send back the excess energy produced to your local electric utility company and get credits on your utility bill, which helps reduce your electric bills. 

Similarly, by using solar batteries, you can reduce your energy consumption from the grid but which results in lower energy bills.

A solar system without solar batteries will help you save money, while those with a solar battery storage system will store excess energy for your use. A win-win investment for you!


3. Reduce CO2 Footprint

Unlike generators and other energy systems, solar power systems and batteries do not release any harmful greenhouse gases or create pollution than traditional fossil fuels. Solar power systems and batteries are responsible for generating clean and free electrical energy.

As a result, solar power systems and batteries allow you to reduce your home’s carbon footprint, bringing you closer to self-sufficiency. This is perfect for those who want to “go green” and reduce pollution. Go green and be a helping hand to our mother earth.


4. Increase Energy Independency

If you don’t like relying on off-grid electricity, then solar batteries are perfect for you! Solar batteries reduce the need to draw electricity from the grid and fulfil your electricity needs. 

Solar panels can also help you with this, however, they are not as flexible a solar batteries. With solar panels, you can use the produced energy and the excess goes out into the grid. 

With solar batteries, you can use the generated energy solely for yourself.

Additionally, there are also a few battery storage systems available in the market that can power your home even when the grid is down, sort of like a battery backup. With a solar battery storage system, you can have the desired energy independence.
