What is Solar Battery Storage?
If you want to add batteries to a new or existing solar power system, but aren’t aware of or understand the basics, you have come to the right place. Economic, emotional and environmental reasons have accounted for solar panel systems as being one of the most fastest growing energy sources. Features such as cost-efficiency, reliability and a higher uptake of new technologies are of main interest, with the Solar Industry doubling in size in 2016, as according to the Solar Energy Industries Association. So, what is solar battery storage? Keep reading to find out more.
The high demand of solar energy has led to the development of another renewable energy technology: solar batteries that can store additional solar energy for later use. Companies such as LG and Sonnen create batteries such as the LG Chem and the sonnenBatterie which can be installed with solar panels to produce solar storage systems for your home. Read more about residential solar batteries and discover if you need to install a solar-plus storage system for your home.
Batteries are becoming more and more cost effective over the time thanks to the promise of self-sufficiency. Energy storage in 2018 can make significant financial sense in rare cases for some solar owners who have the desire to become independent of electricity companies. Since energy storage is a big investment, make sure you know the fundamentals before you part ways with your money.
Now, most importantly, what is a solar battery storage? A solar battery storage is a device that is connected to a solar power system that stores electricity for later consumption. The electricity stored is then consumed during peaks in energy demand, whether that is during the night and or during power outages. This is most common scenario in office and residential buildings.
With Australian homeowners paying excessive rates to buy electricity (25 –54c per kWh) but receiving a penny for electricity exports (0-18c per kWh), this new breed of battery packs can help save money and allow use of solar-generated electricity 24 hours a day.
How is solar energy stored in batteries?
Now that you understand what is a solar battery storage, it is important to consider how solar energy is then stored in batteries. Solar batteries convert the DC energy produced by your solar panels and store it for later use as an AC power. Solar batteries have their own inverter in some cases and offer an fully integrated conversion of energy. The higher the capacity of your battery, the more solar energy it can store.
When you install a solar battery in your solar panel system, you can store excess solar power at home rather than sending it back into the grid. If your solar panels produce more electricity than you need, the battery will be charged with excess energy. Later, when your solar panels do not produce electricity, you can use the energy you have previously stored in your battery at night. Only when your battery is fully charged you will send energy back to the grid and only utilise power from the grid when your battery is depleted.
In practice, this means that households with solar-plus storage can store excess solar energy on site for later use if the sun does not shine. As a perk, because solar batteries store energy at home, they also provide short term and reliable backup power if there is an outage in your area.
