Solar Energy Storage System

How Solar Batteries Work?

Solar panel systems have become one of the fastest-growing sources of energy in Singapore. According to National Day Rally speech, PM Lee said recently, : “we should treat climate change defence like we treat the Singapore Armed Forces — with utmost seriousness… These are life and death matters.” Singapore has enough land area to generate significant amounts of electricity from the sun (150 to 250 MW of ground-mounted solar power could be deployed per square km).

The popularity of solar power has led to the rise of another renewable technology: solar batteries that can store extra solar power for later use. Companies like LG and BYD are developing batteries that can be installed with solar panels to create “solar energy storage system” for your home. Read on to learn more about residential solar batteries, and find out if you should consider installing a solar energy storage system for your home.

Solar Energy Storage System : Solar Batteries For Home

To appreciate why you might choose to install a solar energy storage system for your home, you first need to understand how a standard home solar PV system functions.

The typical solar energy system includes solar panels, an inverter, equipment to mount the panels on your roof, and a performance monitoring system that tracks electricity production. The solar panels collect energy from the sun and turn it into electricity, which is passed through the inverter and converted into a form that you can use to power your home.

The vast majority of residential solar energy systems are connected to the electricity grid (or “grid-tied”). When your panels are producing more electricity than your home needs, the excess is fed back into the power grid. Conversely, when your home needs more electricity than your solar panels are producing, you can draw power from the electric grid.

In most cases, you receive a credit on your energy bill for the electricity you send back to the grid. Later, when you are using more electricity than your solar panels have generated, you can use those credits instead of having to pay more to your utility. This process is known as net settlement.

How Is Solar Energy Stores in Batteries?

Solar batteries work by storing energy produced by your solar panels and storing it as for later use. In some cases, solar batteries have their own inverter and offer integrated energy conversion. The higher your battery's capacity, the more solar energy it can store.

When you install a solar battery as part of your solar panel system, you are able to store excess solar electricity at your home instead of sending it back to the grid. If your solar panels are producing more electricity than you need, the excess energy goes towards charging the battery. Later, when your solar panels are not producing electricity, you can draw down the energy you stored earlier in your battery for night use. You will only send electricity back to the grid when your battery is fully charged, and you will only draw electricity from the grid when your battery is depleted.

What this means in practical terms is that homes with solar energy storage system can store excess solar power onsite for use later when the sun is not shining. As a bonus, since solar batteries store energy at your home, they also offer short-term backup power in the event that there is a power outage in your area.
