4 Things You Need To Know About Solar Battery 

Solar batteries are an essential component of household energy independence. They are intended to work with a solar charger controller or solar inverter to supply backup power. You can use a solar battery to store excess electricity generated by your solar panels during the day and utilise it as needed later.

What is a Solar Battery? 

A solar battery is a type of battery that stores energy generated by a solar PV system for later use. It enables you to keep appliances operating when the sun goes down, or there is a power outage. You can manage your home mostly on solar power if your rooftop solar system and storage are large enough. Batteries also reduce the issue of rising electricity prices and falling feed-in tariffs.

Types of Solar Batteries

Solar batteries are handy in this circumstance. They aid in the storage of surplus energy created throughout the day, allowing you to get through the night. Solar batteries are classified into several categories, each with its criteria. Choosing the best is determined by cost, longevity, installation, and other aspects discussed later. Typical examples include:

1. Lithium-Ion Batteries

This is the most extensively used battery on the market. Lithium batteries are more compact and lighter than other types. Their lifespan is longer than lead batteries, but they are slightly more expensive.

2. Lithium-Ion Batteries

Renewable energy sources have used these batteries for decades. These are the most affordable, making them ideal for families that require an extensive energy storage system. 

3. Saltwater Batteries 

Saltwater batteries are a new technology that is sweeping the industry. It does not include heavy metals, unlike lead and lithium. Instead, saltwater electrolytes are used.

What Are the Benefits of Solar Energy Storage?

Storing excess energy is critical for getting the most out of any solar panel system. It may result in cost savings, more efficient electricity networks, and lower fossil fuel emissions. There are several significant advantages of storing solar energy:

  • Balancing Electric Loads: Energy storage enables surplus energy to be saved for peak demand. In terms of renewable energy, storing excess electricity helps the lights stay on even after the sun goes down.
  • Filling in the gaps: The short-term solar energy storage enables steady electricity flow during generator outages caused by passing clouds or regular maintenance.
  • Energy Resilience: The electricity grid is prone to disturbances and outages caused by various factors, including wildfires and extreme weather. Solar energy storage offers a protective bubble during disruptive occurrences by decentralising where one acquires energy.

How Long Can Solar Batteries Last?

Specific criteria must be considered to calculate how long solar batteries will survive. They contain the quantity of energy used in your home daily if you have a grid connection and the power and capacity ratings of the batteries.

A typical home consumes around 30 kilowatt-hours, according to the US Energy Information Administration. Because a standard battery has a capacity of roughly 10 kWh, you may need three batteries to power your home.

Without another energy source, you may need to add a couple more batteries to keep the lights on all night. The quantity of energy stored can also be affected by the number of hours the solar panel generates electricity.

Cloudy days can also occur, resulting in lower electricity output. It is critical for homes that want to withdraw from the electricity grid to install enough power to last several days.
