Choosing the Right Solar Batteries for Your System

Certain specifications are used when it comes to the evaluation of solar batteries. Some of the factors that you should consider are the amount of power it can provide and how long it would last before you need to replace it again. It’s essential to learn all the criteria and compare several brands in the market before deciding to buy them.

When it comes to comparing your options, you may come across different specifications and product varieties. What you need to find out is a battery’s depth of discharge, power ratings, capacity, warranty, round-trip efficiency, and the brand manufacturer to ensure that you’re getting a high-quality one.

Capacity and Power

Capacity is the amount of electricity that the batteries are allowed to store. The solar battery should have features where the energy is stackable. This means that you can get extra capacity and multiple batteries at the same time. The capacity is often measured in kWh or kilowatt-hours.

The capacity will give you an idea about the batteries’ size, but they may not give you accurate information about the electricity that it will provide your home at one time. If you want to get the full picture, you may want to consider the power ratings, and they are measured in kilowatts.

You must choose a brand that can give you a higher capacity to run several appliances simultaneously for a longer time. This applies to those with low power ratings. On the other hand, higher power ratings but low capacities may be able to run all the appliances in your house at the same time, but they can only last for a short while.

Depth of Discharge

Many batteries will need to be charged at some time because they are composed of chemicals. The chemical composition should be maintained at a low level, and you shouldn’t wait until 100% are used up because the life of the device will be shortened. Read more about the depth of discharge here:

The depth of discharge is the battery’s current usage, and many manufacturers will specify this. You may want to look at an example of a mobile phone. Which is, you shouldn’t wait until the phone shows 0% before you charge it because it may shorten the lifespan of its batteries.

Instead, the manufacturer may tell you that their brand has a DoD of about 90 percent, which means that owners should never wait until they have used 9kWh before charging their devices. Higher DoD generally means that you can utilize more according to your brand’s current capacity and your needs.

Efficiency in Round Trips

The round-trip efficiency usually shows the amount of energy that can be used compared to the bulk of power that it will take to store it. For example, feeding 5 kWh of electricity only to use 4kWh means that you have an 80% round trip efficiency. What you need to aim for is to look for those with higher efficiencies so you can get the most out of them and not get higher monthly bills.

Warranties and Lifespans

As with any other devices at home, you may tend to drain and recharge your batteries on a daily basis. This device’s ability to hold the electricity charge will gradually decrease as time passes, especially if the more you’re using it.

This is comparable to cell phones’ efficiency, where you start to notice that it will quickly decrease its charge as it gets older. It doesn’t hold as much energy when you first bought it. As an example, you may have a battery that has a 10-year warranty with 5,000 cycles. As the decade is nearing, you may notice that it can only retain about 70% of its original storage abilities. It will lose more than 30% or even more than this, and it may be time for a replacement.

You can always look for guarantees and warranties to ensure that the batteries will have specific years of becoming useful to the solar panels. Many manufacturers will ensure that their brands will hold a certain percentage throughout the warranty period, and you can get an expert to know if it’s time for a replacement.

Rebates on Solar battery storage

Some states offer rebates on solar batteries. There are some criteria such as the minimum size of battery and maximum household incomes, but it’s worth investigating Battery Storage Oxfordshire to see if you can save. The cost of batteries is still quite high and not really worth it in my view.

With the health feed-in tariffs being paid for excess power production through the day, you can use the grid as a virtual battery and still reduce your power bill by 80 – 90%.
