Most homeowners and business owners appreciate the importance of solar batteries, increasing their demand in recent times. This is due to the unreliability of power supply in some areas and the interest in looking for alternative ways to generate eco-friendly electricity.
Solar energy has numerous benefits and is one of the cheapest and most reliable renewable energy sources. However, it would be best to choose the correct solar battery to ensure a long-term and efficient solar energy system. The right solar battery can collect energy from the sun and store it for later use, guaranteeing a dependable, consistent, and sustainable power supply.
You need to consider specific factors before getting a solar battery. The outline below can take you through several features to look for in a solar battery:
Capacity And Power Rating
The solar battery’s capacity refers to the quantity of electricity it can save. It is usually measured in kilowatt- (kWh) or Ampere hours (Ah). However, most solar batteries can’t run at their maximum capacity. For example, the capacity of a standard solar battery is 90%. Hence, a battery with a capacity of 10kW can only utilize 9kW at its best.
Aside from the solar battery’s capacity, you must check the solar battery’s power rating. This refers to the amount of electricity delivered by the solar battery within a given time. It’s crucial to note that a solar battery with low capacity and a high-power rating can run all your appliances for a few hours. However, a solar battery with high capacity and low power rating can run some appliances for longer periods.
Warranty And Battery Life
The current market has many battery varieties. However, not all are reliable or trustworthy. When looking for a solar battery, it would be best to purchase from reputable companies such as AlphaESS Solar. You also need to purchase your solar battery from a manufacturer with the best warranty. The manufacturer specifies the warranty based on the number of draining and charging cycles the battery can endure or the number of years it can perform.
Therefore, you can determine the lifespan of a solar battery by checking its brand and the amount of capacity it can lose over time. Practicing proper maintenance measures can further extend the lifespan of a solar battery.
You also have to consider choosing a battery type that can serve all your needs. There are three types of batteries, and they are:
- Flow battery – is a type of battery that uses pumped electrolytes like zinc bromide or vanadium ions and chemical reactions to store and release the charge. Its key advantage is it doesn’t lose its charge. Moreover, flow batteries are recyclable and can last for more than ten years. However, flow batteries are new to the market, hence, being expensive and hard to maintain.
- Lead-acid battery – is more conventional and pocket friendly. However, lead-acid batteries have a slow charge cycle. They can also be bulky, hence unsuitable for most common uses.
- Lithium-ion battery – is a battery type that most people prefer since it doesn’t overcharge or get damaged easily. Moreover, lithium-ion batteries can withstand various ambient temperatures and last for more than ten years. However, lithium-ion batteries are hard to recycle.
- Tubular battery- is a sizeable lead-acid battery typically used in Tier two and three cities that experience prolonged power outages. Tubular batteries have significant charging and discharging rates.
Depth Of Discharge (DoD)
The DoD refers to the amount of electricity your solar battery can utilize. Most manufacturers describe a battery’s DoD since solar batteries constantly need to reserve some charge for optimal performance. A 10kWh battery with a 90% DoD can allow you to only use 9kWh before recharging it since failing to retain some charge lowers the battery’s lifespan. Therefore, it’s crucial to look for a solar battery with a higher DoD.
Also known as round trip efficiency, it refers to the quantity of energy the battery can produce compared to the amount of energy it receives. For instance, if a solar battery receives and stores 5kWh and then produces 4kWh, the round-trip efficiency of that solar battery is 80%. Therefore, you need to look for a solar battery with a high round trip efficiency value for its cost-saving advantages.
There are specific safety requirements that all solar batteries must meet to be certified for home and business installations. Therefore, you need to look for a certified solar battery to guarantee your safety. However, some have even surpassed the government-mandated safety requirements, hence being safer than the rest. Therefore, it’s crucial to check for the safety quote of a solar battery before purchasing it.
An effective solar battery is a crucial investment since it can serve you for many years. However, it would be best to consider some factors to get the correct solar battery that meets your requirements. The outline above can help you know the key features to look for in a solar battery.
