Do you often experience power interruptions? Do you wish to save money by using clean and naturally-sourced energy throughout the night?
Regardless of your electrical concerns, we have a sustainable, long-term solution for you – a solar battery storage system!
It is no secret that solar battery storage can store electricity generated by solar panels, allowing you to harness surplus energy when weather or power conditions may be unfavourable.
To help you understand every detail of solar battery storage, we have all you need to know in this article, from its benefits, types, and installation process. We've even answered some of your frequently asked questions.
Let's get started!
A solar panel battery storage system is known for storing electricity, particularly excess energy generated from the sun through the solar panels installed on your roof or open area.
To gain a more in-depth look into everything these systems offer, here is a list of benefits you can receive from your solar battery storage system.
The first on this list is something we have repeatedly mentioned: its ability to store excess energy already generated by your solar PV system.
Solar panel battery storage works like this:
After the four steps above, the DC electricity passes through a compatible inverter. Then, it is converted into alternating current (AC) for different uses, such as:
Another benefit of including solar battery storage in your solar PV (photovoltaic) system is the reduced carbon footprint and lower emission level due to lower reliance on fossil fuel-powered electricity.
Power stations that produce electricity contribute 15.8% of all carbon dioxide emissions in the United Kingdom.
With the help of energy storage through solar batteries installed in your solar system, you can diverge from using non-renewable energy and, in turn, help the environment by reducing greenhouse gases.
Since your primary renewable energy source will be the sun as opposed to the traditional grid, you can significantly decrease your monthly electricity bill(by approximately £300) and save money each month.
Integrating a reliable home battery system in your existing solar PV systems will also help you earn money through financial benefits and grants in the UK, like the following:
Knowing what a solar battery can do is one thing. It is equally essential to know the different types of solar batteries to help you know what you are dealing with.
Here are the three types of solar batteries you can use and how they work!
A lithium-ion battery for solar panels is one of the market's most popular solar batteries, known for its energy density and high solar electricity generation.
Lithium-ion batteries have these characteristics because of their capacity for a more efficient power transfer. They can store more solar power and discharge a useable capacity of 70% to 90%.
Aside from the benefits mentioned above, lithium-ion batteries are also known for their durability and resilience, mainly when there is an imbalance in the electric battery supply.
Another type that the public chooses aside from lithium batteries is the lead-acid battery, which is known for being highly tolerant to extreme temperature changes, as well as being quite affordable.
Based on our research and experience, battery storage systems like this can survive every temperature change, making them reliable, durable, and efficient at a low cost.
More importantly, it has excellent energy density, similar to lithium-ion batteries. However, it only discharges 50% of its useable capacity in exchange for its long life cycle.
The third type of solar battery that completes a solar panel system is the flow battery, known in the market for discharging a usable power capacity of up to 100%.
You should also know that storage systems utilising a flow battery can perform a full discharge consistently for its entire life cycle (20 years at most).
Aside from its deep discharge, its larger battery capacity at a relatively low cost for an average household, not to mention its long life cycle, makes it a dependable solar battery.
However, it is mainly used to store solar energy in industrial settings and not in a household solar panel system.
Based on our experience, most households with an existing solar panel system want to understand the installation process of solar batteries, and rightfully so.
We know that one way or another, you will also need this awareness of the solar panel and battery installation process for present or future use.
So, here is a step-by-step guide on installing a solar battery. Read through!
First, you must assess your home's power needs. You can do this by determining the following:
After that, you can divide the number determined above by the minimum and maximum power wattage available on the market. It is vital that you do both to determine the range of your solar energy needs.
Once you have determined it, you can choose the design and number of solar panels and the types of solar charge controllers and solar batteries that will best meet your needs.
Next, after identifying your power needs, you can proceed with the other solar battery systems' design requisites, such as:
After considering everything, you can now continue installing the battery systems. Here are the steps you must follow moving forward:
Once all these steps are carried out, you can install solar panels in their proper location to check if the solar energy storage system works appropriately.
Your home battery storage system can help you save on energy bills, provide clean energy, satisfy electricity needs during a power cut, and more.
To better understand the PV system and its battery storage systems, we answered some of the most common questions on energy storage in this section.
The best solar battery energy storage system for your home is one which utilises lithium-ion or lead-acid batteries because they are equipped with these features:
Moreover, it would also be best if the energy storage you install has the following characteristics:
The solar battery storage systems cost around £2,000 to £7,500, depending on the following factors:
However, the solar panel battery price can still go lower or higher as it will still be based on the factors mentioned.
It will depend on how much energy you need for your household consumption (more energy or less) and how much of your electricity costs you want to deduct from your monthly bills.
Solar batteries can last for at least 5 years, though the highest quality among them will last a quarter of a century.
Of course, this approximation will still depend on whether you buy batteries with characteristics such as:
Always remember that it is not the expensive price of solar batteries that matters, as you also need to consider its capacity and how it will work with your household load and solar panels.
Yes, there are disadvantages when using solar batteries, like:
However, these disadvantages can be offset by the perks solar batteries offer, such as:
Yes, you can connect the panels directly to the battery using a car's battery and low-voltage panels.
However, you must be wary of the following risks that can occur with this setup:
For these reasons, you should connect the solar panels to a battery with the help of charge controllers for a more regulated and efficient energy transfer.
A solar battery as storage for your power is an essential aspect of solar panel systems. It provides several benefits, particularly when it comes to reducing bills and ensuring more consistent energy usage.
So, the best option to take when you frequently experience power cuts or if you want to save bills by using clean energy is to use an efficient solar battery.
We hope that by reading this article, you can become more equipped and capable of addressing your solar battery needs!
