7 Facts to Consider Before You Buy a Solar Battery for Residential Settings

A solar power installation calls for a robust investment in the beginning but it pays heftily in the long run for sure. Most of the time, the systems need a panel, inverter, and a controller along with the expertise of an electrician to establish connect between apparatuses to make them run. In this system, the battery plays a crucial role as it is the lifeblood of the power system. And, when it comes to buying the solar battery, people often confront various issues that require much brainstorming. This blog sheds light on some of the most crucial factors to consider while buying a solar battery for home settings or even for a commercial venture.

1. The Battery Technology

There are mainly 4 types of solar batteries available in the market. These include:

  • Lead Acid
  • Lithium-ion
  • Nickel-cadmium, and
  • Flow batteries.

Lead acid batteries are considered to be not that much costly but they need regular maintenance. These batteries have been around for many decades and are very popular. Lithium-ion batteries, on the other hand, are expensive but have become the most popular choice for home energy needs because they offer a very long lifespan but need no maintenance at all. Nickel-cadmium batteries are considered to be the best choice for commercial-scale undertakings.

It is because they need no complex management system and can work very effectively and efficiently even at extreme temperatures. As for flow batteries, they are not only expensive but also big in size. This is the reason they are comprehensively used for large-scale battery storage. Out of these 4 battery technologies, you need to choose the one that can provide you with power, performance, and peace of mind from maintenance.

2. Warranty

Warranty is also a very important aspect associated with any kind of solar battery. Just like your mobile and laptop battery, even the best solar battery in India degrades over time when charged and used regularly. After a certain period, it starts losing its capability of holding and storing the current. Luckily, almost all the reputed manufacturers and suppliers of solar batteries in India provide warranties on their products with the assurance that they will keep rendering high performance to a certain level.

Warranties also ensure that the manufacturer is also confident when it comes to the overall built quality of the battery. Lithium-ion batteries are well known to offer the longest warranty period which might be up to 10 years whereas lead acid batteries come with just one year of warranty. However, some companies have started manufacturing a newer and more innovative range of lead acid batteries that come with a two-year warranty. Therefore, when you are going to buy a home solar battery, you need to be very specific about the warranty factor to enjoy complete peace of mind for a longer duration.

3. Lifespan 

The lifespan of home solar batteries might be anywhere between 3 to 15 years. Lifespan to a large extent depends upon the gravity of usages, and a large number of other factors. Some batteries when maintained properly offer an excellence lifespan while others retire just after 3 or 4 years. You are advised to carry out comprehensive homework concerning the lifespan of solar batteries for your home.

4. Round-Trip Efficiency

Round-trip efficiency is the amount of energy present in a solar battery for homes in respect of the amount of energy that the operating system of the battery uses. When any battery delivers energy, some energy is constantly utilized within the framework. Buyers need to check the round-trip efficiency of a solar battery before making the final buy. You need to buy a solar battery that comes with a high round-trip efficiency. Also, make sure that you are losing no extra amount of energy that your home appliance could run on.

5. Compatibility- AC coupled or DC coupled

While buying any solar battery for a home, you need to be confirmed whether it is AC-coupled or DC coupled. You must avoid all those batteries that don’t match your solar panel wiring. In AC-coupled storage, a large number of energy changes are there. On the other hand, in DC storage, the conversion of energy takes place only a single time. AC coupled system is the most common storage framework. If you are already having a solar energy framework installed at home, then you need to buy an AC-coupled battery.

6. Depth of Discharge

The capacity available for usage is called Depth of Discharge (DoD). It is a capacity that can be utilized in a hassle-free way with no need to strain the battery’s system. In this connection, flow batteries are believed to have a higher DoD when compared to other different batteries. They are well known to have 100% Depth of Discharge (DoD), and this means that you can keep using them until they are completely drained out. Lithium-ion batteries come with a 90% DoD, and at a point in time when you utilize 90% of its capacity, it needs a recharge against any damage.

7. Cost and Safety

And finally, cost and safety need to be considered. You need to make sure that the solar battery that you are going to buy meets all your safety requirements. Safety requirements need to be adhered to during the installation process. Overheating is closely associated with the safety of the battery and those with coolers can stay unaffected during overheating. Therefore, be particular about the cooling aspect.
