How Does Solar Battery Backup Work: What You Need to Know

Traditional battery backup systems that primarily relied on coal stations and other fossil fuel sources gained popularity because of their ability to provide backup power during outages. However, as the importance of sustainability and renewable energy grew, solar battery backup systems emerged as a superior alternative. Solar energy is extremely important due to its many benefits and its ability to address key energy and environmental challenges.

The top benefits of solar energy solutions include sustainability, cost-effectiveness, energy independence and security, eco-friendly, and more. By embracing solar battery backup systems, individuals and communities in the UK can contribute to a more resilient, greener energy landscape.

How Does Solar Battery Backup Work?

Over the years, the number of coal power stations in the UK has significantly decreased due to the country’s commitment to transitioning to cleaner and more sustainable forms of energy. The answer to the question “How many coal power stations are in the UK?” is two. The country plans to phase out unabated power stations that rely on fossil fuels by 2025. Solar battery backup systems, e.g., battery backup, are considered the future. They have transformed the way we harness and store energy, offering a sustainable and reliable solution for powering homes and devices.

In order to learn how the solar battery backup system works, it is important to learn about its key components, the process of solar power generation, and how the stored energy is converted into usable electricity.

1. Components of a Solar Battery Backup System

A solar battery backup system consists of two primary components: the solar panel and the power station. Together, they work seamlessly to capture, store, convert, and distribute solar energy for various applications.

The solar panel is the key component of the solar battery backup system that is responsible for capturing sunlight and converting it into electricity. It is composed of multiple photovoltaic (PV) cells, and it utilizes the photovoltaic effect to generate an electric current when exposed to sunlight. The PV cells contain semiconductor materials, e.g., silicon, that release electrons when photons from sunlight strike them. These freed electrons create a flow of direct current (DC) electricity.

The power station consists of high-capacity batteries, usually lithium-ion, that store the excess electricity produced by the solar panels. The power station features a Battery Management System (BMS) that ensures efficient energy storage and retrieval by regulating charging and discharging processes and protecting the batteries from overheating, deep discharging, and overcharging.

Apart from storing energy, the power station contains an inverter, which can convert the DC electricity from the batteries into AC electricity so that you can use it to power up your household appliances and devices.

2. How Do Solar Panels Generate Power?

Solar panels harness the abundant energy from the sun and convert it into electricity via a process called the photovoltaic effect. Here’s how the process works:

  • Photovoltaic Cells: As mentioned before, solar panels are composed of photovoltaic (PV) cells made of layers of semiconductor materials like silicon. The silicon in PV cells has unique properties that allow it to generate electricity when exposed to sunlight.
  • The Photovoltaic Effect: When sunlight, which contains tiny packets of energy called photons, strikes the surface of a solar panel, it interacts with the silicon atoms in the PV cells. This interaction causes the electrons in the silicon atoms to gain energy and break free from their atomic bonds.
  • Creation of an Electric Field: The photovoltaic cells are designed in a way that creates an electric field within them. This electric field facilitates the movement of the freed electrons, creating a flow of electric current.
  • Collection of Electrons: The electric field within the PV cells directs the freed electrons towards conductive metal plates within the cell structure. These conductive elements collect the electrons and create a flow of DC electricity within the solar panel, which is then transferred to the battery.

3. How Do Power Stations Convert Solar Power Into Usable Energy?

DC electricity is not directly usable for most, if not all, household devices and appliances. This is because they operate on AC (alternating current) electricity. To make the electricity compatible, power stations and solar battery backup systems use an inverter. The conversion process of DC to AC electricity involves these key steps:

  1. The inverter in the solar battery backup system receives the DC electricity from the battery. This DC input is typically in the form of a regulated, stable voltage that the battery system provides.
  1. Before the DC power is converted into usable AC, the inverter ensures that the voltage is consistent and regulated. This ensures a stable power supply for connected devices/appliances.
  1. The inverter uses a technique called pulse width modulation (PWM) or switching to convert the direct current electricity into alternating current electricity. PWM involves rapidly switching the DC power on and off to simulate an AC waveform. By adjusting the duration of the on and off states, the inverter can control the output frequency and voltage to match the desired AC power characteristics.
  1. The inverter utilizes electronic components such as capacitors and transistors to generate the alternating current waveform. The switching action of these components creates a series of pulses that approximate the shape of a sine wave, which is the standard waveform of AC power.
  1. After the initial generation of the AC waveform, the inverter of the solar battery backup system uses filters to smooth out the pulsed waveform and reduce any unwanted noise or harmonics. Furthermore, the inverter ensures that the output voltage remains within acceptable limits and matches the required voltage for the connected devices.
  1. The inverter continuously monitors the load demand and adjusts the power output accordingly. This regulation ensures that the connected devices or appliances receive a consistent and stable supply of AC power, even when the load requirements change.

Solar battery backup inverters typically include various safety features to protect the system and the connected devices from potential damage or hazards.
