Further, the country aims to generate 100% zero-carbon energy by 2035.[1]
This transition has made solar energy bank solutions a popular option for households and businesses seeking to embrace sustainable means of energy production.
But one question remains if you don't have a comprehensive grasp of solar energy: Is it worth buying a solar portable power bank in the UK?
In this article, we will explore the benefits, costs, and scenarios where owning a solar energy generator for house and business can make a significant difference in day-to-day life.
Basics of Solar Energy Bank Explained
1. What Is A Solar Energy Bank?
A solar energy bank is integral to a solar-powered energy production system, including the rooftop solar system, balcony solar system, and portable solar generator. It is a battery system that stores excess energy generated by PV panels during shiny days, which is beneficial on cloudy days and at night. It can be a large-scale system that can power an entire building or a mini-sized version designed to power personal electronics like mobile phones.
2. Types of Solar Energy Bank Cells
With different battery technologies, solar energy banks can utilise different battery cells. Generally, there are three types of battery cells widely used:
- Lead-Acid Batteries
Lead-acid batteries can be said to be the rechargeable battery that claims the longest history. They are typically popular in commercial solar setups because they are affordable and reliable. Lead-acid batteries offer reliable performance and can handle a wide temperature range, making them applicable for both hot and cold climates with proper safety features.
Generally, you can see two types of lead-acid batteries: flooded and sealed. Flooded batteries contain liquid electrolytes and require maintenance, while sealed batteries use sealed electrolytes and require little maintenance, which makes these batteries often referred to as maintenance-free batteries.
- Lithium-ion Batteries
Lithium-ion batteries have a more advanced system that allows users to store more energy within the battery. They are compact and lightweight and have a longer lifespan than lead-acid batteries. You can expect good service for 10 years or more.
They also offer fast charging, which is essential for a solar system, as sunlight hours are limited in the UK. Plus, you do not need to fully use the battery before recharging it. However, they are a bit costly and can also catch fire if not managed properly.
- LiFePO4 Batteries
LiFePO4 (Lithium Iron Phosphate) batteries are considered the best kind of batteries for solar systems. They use lithium iron phosphate (LFP) as the cathode component for better performance than other regular lithium batteries. They also have greater longevity and stability than traditional lithium-ion batteries.
They charge quickly and more efficiently, making them an ideal option for small devices and solar power systems. They consist of non-flammable electrolytes that reduce the chances of overheating and fire. Their overall exceptional performance makes them suitable for portable solar systems and various solar energy uses.
3. Features of a Solar Energy Bank
- Stable Load Backup
A solar energy bank offers a consistent power supply when solar panels are producing less energy due to low sunlight, nighttime, or during power outages. This backup storage is extremely beneficial for areas where weather conditions are unpredictable. It ensures you receive a stable power supply in times of power disruptions.
- Off-Grid Power Supply
A solar energy bank enables complete energy independence, allowing users to produce and store their own power. This feature makes it convenient for adventure lovers to explore the outdoors without cutting off from the world. Users can charge their devices and power their appliances even in the middle of nowhere. This feature also facilitates houses in remote or rural areas with unreliable grid connections.
- Scalability
Many solar energy banks feature modular designs. Therefore, users can start with a basic battery setup and gradually add additional battery packs as their energy needs grow. This scalability makes these energy banks highly adaptable, whether for small-scale uses such as powering personal electronics or large-scale systems for homes and businesses.
Is It Worthwhile Buying a Solar Energy Bank in the UK?
The answer is yes. A one-time investment in a solar energy bank can help you reap benefits for years. Let's examine the expected cost of owning a solar energy bank along with its long-term benefits so you can decide for yourself.
Costs and Other Factors to Consider:
- Solar Energy Bank Costs
In the UK, the cost of a solar energy bank varies mainly by capacity and battery type. Small systems less than 1 kWh typically cost you hundreds of pounds, while bigger battery systems (3-15 kWh) can cost you thousands of pounds and even up to 10,000 pounds. Typically, LiFePO4 batteries can be more expensive than lead-acid batteries due to their more complex manufacturing process and better performance.
Additionally, when it is a larger-scale battery energy storage system, you need a professional team to help with proper installation to ensure safe operation. This can further add to the cost of having a solar energy bank.
