The solar battery is an important addition to a solar panel system. Solar batteries let you store energy and use stored energy when the panels aren’t generating enough energy to power your home. Prior to going for a solar panel battery, most homeowners wonder how a solar battery works with a solar power system.
What is a Solar Battery?
A solar battery is an electric device that can be added to a solar power system to store the excess electricity generated by the solar panels. The stored energy in the best solar battery can be used to power your home and appliances at times when the solar panels are not generating sufficient electricity. For example, during cloudy days, at night, or during power outages, you need to use stored energy.
The main purpose of a solar panel battery storage system is to take full advantage of the electricity generated by the solar panels. Without battery storage for solar panels, excess electricity generated is fed back into the grid.
Advantages of Solar Panel Battery Storage
1. Greater energy security even if the grid goes down
2. Save on electricity costs and reduce your monthly bills
3. Reduce the carbon footprint
4. No-noise and effective power backup
5. Energy independence and self-sufficiency
6. Storage of excess electricity generated
Solar Battery Types
The two most common options for solar battery storage are lithium-ion batteries and lead-acid batteries.
Lithium-ion battery
1. Most common type of solar battery in the market today
2. Reliable and long-lasting
3. Higher depth of discharge (DoD)
4. Requires less charging time
5. Compact in size
6. Guaranteed warranty of at least 10 years
7. Limited servicing is required
Lead-acid battery
1. Ideal off-grid power storage option
2. Less expensive
3. Low depth of discharge
4. Shorter lifespan (5-10 years)
How is Energy Stored in a Solar Panel Battery?
Solar battery storage works by storing excess solar energy generated by the PV system. The best solar battery safeguards a house from power interruptions and helps reduce reliance on the grid’s electricity supply. Keeping in mind the solar panel battery price, it is a great long-term investment.
Here is How Solar Batteries Work
Coupling refers to the way a solar battery is connected to the solar PV system.
DC-coupled storage
1. Sunlight hits the solar panels, which are converted into direct current (DC) power.
2. The electricity enters the battery and is stored as DC electricity.
3. This DC current leaves the battery and is transformed into alternating current (AC) by an inverter.
4. The AC current generated is used to power the home.
AC-coupled storage
1. DC current generated by solar panels first enters the inverter and is converted into AC current.
2. The AC current is used to power the home.
3. Excess electricity flows through another inverter to change into DC current, which is stored in the battery for future use.
4. To use the energy stored in the battery, DC current must again flow through an inverter to become AC current.
If you are considering investing in solar batteries, it is important for you to know how a solar battery works. With the best solar battery, you can have complete control over when and how to use solar energy. Also, you don’t need to rely on grid electricity.
