CHOOSING A SOLAR BATTERY

Solar Inverter Installation

Choosing the right solar battery might be a difficult task sometimes because of the many varieties of products in the market. Solar batteries come in different sizes and capacities. Solar batteries vary in components and strength. It is important to also note that even solar batteries with the same capacity and size sometimes vary in price too.

In the midst of these varieties, yet it is very important to choose the right solar battery that would serve the precise purpose you chose it for. Trust me, you don’t want to choose the wrong product. A poor choice of solar battery can be frustrating and make you believe in a world where a good solar inverter system never exists. As much as solar batteries are important is choosing the right solar and inverters

So, in this article, we will be discussing the important things to look at when choosing a solar battery.

Capacity and Power

It is important to first check the total amount of electricity that a solar battery can store in kilowatt-hours (kWh). Most home solar batteries are designed to be “stackable” which allows the inclusion of multiple batteries. This helps to have a good storage system to increase battery capacity as desired.

While capacity tells you how big your battery is, it doesn’t tell you how much electricity a battery can provide at a given moment. To get the detail, you also need to consider the battery’s power rating. In the context of solar batteries, a power rating is the amount of electricity that a battery can deliver at one time. It is measured in kilowatts (kW).

A battery with a high capacity and a low power rating would deliver a low amount of electricity (enough to run a few crucial appliances) for a long time. A battery with low capacity and a high power rating could run your entire home, but only for a few hours.

Debt of Discharge (DoD)

Most solar batteries need to retain some charge at all times due to their chemical composition. If you use 100 percent of a battery’s charge, its useful life will be significantly shortened. 

The depth of discharge (DoD) of a battery refers to the amount of a battery’s capacity that has been used. Most manufacturers will specify a maximum DoD for optimal performance. For example, if a 10kWh battery has a DoD of 90%, you shouldn’t use more than 9kWh of the battery before recharging it. Generally speaking, a higher DoD means you will be able to utilize more of your battery’s capacity.

A battery’s round-trip efficiency represents the amount of energy that can be used as a percentage of the amount of energy that it took to store it. For example, if you feed five kWh of electricity into your battery and can only get four kWh of useful electricity back, the battery has 80 percent round-trip efficiency (4 kWh / 5 kWh = 80%). Generally speaking, a higher round-trip efficiency means you will get more economic value out of your battery.

Battery life & warranty

For most uses of home energy storage, your battery will “cycle” (charge and drain) daily. The battery’s ability to hold a charge will gradually decrease the more you use it. In this way, solar batteries are like the battery in your cell phone – you charge your phone each night to use it during the day, and as your phone gets older you’ll start to notice that the battery isn’t holding as much of a charge as it did when it was new.

Your solar battery will have a warranty that guarantees a certain number of cycles and/or years of useful life. Because battery performance naturally degrades over time, most manufacturers will also guarantee that the battery keeps a certain amount of its capacity over the course of the warranty. Therefore, the simple answer to the question “how long will my solar battery last?” is that it depends on the brand of battery you buy and how much capacity it will lose over time.

For example, a battery might be warrantied for 5,000 cycles or 10 years at 70% of its original capacity. This means that at the end of the warranty, the battery will have lost no more than 30% of its original ability to store energy.  

Manufacturer

Choosing a battery based on manufacturers reputation most times can put you in the better sides of the odds. Companies with good history of durable batteries will likely offer more lasting and reliable battery while otherwise might be a 50:50 risk.
