By harnessing the power of the sun, a renewable and clean energy source, solar battery storage systems reduce the carbon footprint of a household. It's a direct contribution to the fight against climate change.
3. How Does Solar Battery Storage Work?
The mechanics behind a solar battery storage system might seem complex, but the concept is straightforward. Let's break it down into simple steps.
Solar Energy Generation
The process begins with your solar panels. As the sun shines, your solar panels absorb the sunlight and convert it into direct current (DC) electricity.
Conversion to AC Electricity
The DC electricity is then sent to an inverter, which transforms it into alternating current (AC) electricity. This AC electricity is what powers the appliances in your home.
Storing Excess Energy
During peak sunlight hours, your solar panels may generate more electricity than your home needs. Instead of sending this excess power back to the grid, a solar battery storage system stores it for later use.
Using Stored Energy
When the sun goes down or during power outages, your solar battery steps in. It discharges the stored energy, supplying your home with electricity and keeping your lights on.
4. Types of Solar Batteries
There are two main types of batteries used for solar energy storage: lead-acid (AGM and gel) and lithium-ion. There are several other types available, such as redox flow batteries and sodium-ion batteries, but we'll focus on the two most common. Most modern energy storage systems use rechargeable lithium-ion batteries and come in many shapes and sizes and can be configured in many ways.
Lithium-Ion batteries are currently the most common choice for solar energy storage due to their high energy density, long lifespan, and relative safety. They offer a good balance of cost, performance, and longevity. However, they are not without drawbacks. For instance, they can degrade if not properly maintained, and their production process has a high environmental impact.
Lead-acid batteries are a tried-and-true technology that's been used for over a century. They're often less expensive than lithium-ion batteries and are fully recyclable. However, they tend to have a shorter lifespan and lower energy density, meaning they take up more space for the same amount of energy storage.
Flow batteries are a relatively new type of battery that's ideal for long-duration storage. They have a unique design that separates the energy storage from the power generation, allowing for more flexibility in system design. However, they're usually more expensive and less energy-dense than other options.
5. Advantages of Home Solar Battery Storage
