In 2022, the sun proved to be a game changer in the realm of renewable energy.
In fact, sixty percent of the renewable energy sector’s growth last year could be attributed to solar power. This is a testament to the sun’s potential for addressing the world’s growing energy needs.
The most intriguing aspect of this solar revolution is not the sheer volume of energy being generated, but rather how this energy is stored for use when the sun sets or the clouds gather.
Welcome to the fascinating world of solar energy storage. This is a technology that will enable a sustainable future, one solar cell at a time.
To help you understand how solar storage works, we’ve written a guide. Keep reading if you’d like to find out more.
What Is Solar Energy?
Every day, the sun beams down more energy than the entire human race could use in a year. Harnessing this power requires solar panels. These contain photovoltaic cells that convert sunlight directly into electricity.
These cells are made of semiconductor materials, like silicon, that absorb light and knock electrons loose. It is these loose electrons that help to create electricity.
What Is Solar Energy Storage?
Solar energy storage is the solution to one of solar power’s main drawbacks: it can only produce electricity when the sun is shining.
Storage systems capture and store the excess power produced during the day for use at night or during power outages. A great example is the Tesla battery.
It stores energy in an incredibly efficient way. Those who use their home solar panels to charge their Teslas reduce fossil fuels and make great use of the sun’s energy.
The Advantage of Combining Solar and Storage
Combining solar power with energy storage brings numerous benefits. Firstly, it balances electricity loads. Solar power is intermittent.
This means that it produces more energy in the middle of the day when demand is often low, and less in the early morning and evening when demand peaks.
Energy storage can store surplus power and release it when needed. This smoothes out these imbalances.
Secondly, it firms solar generation. Solar power production can dip due to temporary cloud cover or dust on the panels. Energy storage can step in to fill these gaps, guaranteeing a steady supply of electricity.
Lastly, solar-plus-storage provides resilience. If the grid goes down, a home with solar panels but without storage will be left in the dark.
But with storage, the home can keep running on solar power. This can be especially valuable during natural disasters.
Solar storage makes it easier for consumers to embrace a sustainable living lifestyle that’s independent and self-reliant.
Types of Solar Energy Storage
Contrary to what many people think, there are only two main types of solar energy storage: lithium-ion batteries, and lead-acid batteries. Here is what you need to know about these energy storage solutions.
Lithium-Ion Batteries
Lithium-ion batteries are currently the most popular type of battery used in solar power storage, and for good reason. They’re the same type of battery you’d find in a laptop or smartphone, but on a much larger scale.
Lithium-ion batteries are known for their high energy density. This means they can store a lot of power relative to their size. This makes them compact and lightweight compared to other options.
Another advantage of lithium-ion batteries is their longevity. They can endure a greater number of charge and discharge cycles before their capacity starts to degrade, making them last longer.
They’re also highly efficient. They lose very little energy when charging and discharging.
Lead-Acid Batteries
Lead-acid batteries are an older technology that has been used for over a century in applications such as car batteries. They’re generally larger and heavier than lithium-ion batteries, and they have a lower energy density.
This means they take up more space and weigh more for the same amount of storage capacity.
One of the main advantages of lead-acid batteries is their cost. They are typically cheaper than lithium-ion batteries. But they tend to have a shorter lifespan and may need to be replaced more often.
Choosing the Right Battery for Your Needs
There are several factors you should look at when you’re trying to figure out which solar storage solution is right for your needs.
Firstly, consider your budget. If upfront cost is a major concern, then a lead-acid battery may be the better choice.
But if you’re willing to invest more upfront for potentially longer-term benefits, a lithium-ion battery might be the way to go.
Secondly, think about your space constraints. If you have limited space, a compact lithium-ion battery would be ideal.
Next, consider your energy needs. If you use a lot of power or want to be off-grid as much as possible, a higher-capacity lithium-ion battery might be worth the investment.
Lastly, think about the future. With the rapid advancements in battery technology, lithium-ion batteries are becoming more affordable and efficient. They’re also more eco-friendly than lead-acid batteries.
This is one of the reasons why it does not make sense for most people to invest in lead-acid batteries.
How Solar Energy Storage Works
If you are thinking about adding solar panels to your home, you might be wondering how solar energy storage works.
By combining solar and storage, it is possible to make use of the sun’s energy when it is not shining. Solar storage solutions will even provide electricity to your home when the rest of the grid is down.
Keep in mind that the most effective type of solar storage is lithium-ion batteries.
