5 Factors For Choosing The Best Solar Battery?

Ever thought about how you could power your homes or industries in the absence of sunlight? Solar batteries can be of your help here. A solar battery can collect solar energy during the day, and store it to utilize when you need it the best— which makes it a reliable, consistent, and sustainable energy source. 

Solar energy is cost-efficient compared to fossil fuels, however, this doesn’t mean that solar panel installation on roofs can automatically help you save cost. 

Selecting the apt solar battery system can be crucial to make sure that the solar energy system offers long-term value. Hence we need to do the research efficiently before arriving at decisions. Solar batteries can be of various types and every type has unique features. 

There are many aspects to consider and we classify them here to make it easy to acknowledge which one to look for while trying to pick the ideal solar battery for your requirements. 

Tips for choosing the best solar battery for energy storage

  1. Capacity

The capacity of a solar battery is the quantity of electric power it stores. Most solar batteries cannot operate at full capacity. For example, the standard solar battery displays 90% capacity, which means a 10 kW capacity battery uses only 9 kW as the optimum potential. The storage capacity relies on the extent of energy solar panels generate for the past 24 hours. You should find the average output, and multiply this by the number of days you wish the battery to function non-stop before it needs to charge. This means if the average daily output is 5 kW, and you wish to store energy for another 15 days, you require a 75 kWh battery. But, the solar battery storage capacity is based on the maximum daily electricity consumption for your establishment. If the solar battery capacity is not enough, then you won’t receive adequate power for the mentioned duration. 

  1. Efficiency 

This is also termed round trip efficiency, which evaluates the percentage quantity of the energy stored in the battery for your use. For example, if you look at a solar battery with 5 kWh of power charged, it provides only 4 kWh to use which makes the round trip efficiency about 80%. Additionally, for a high-performing solar panel like a 13.2 kW solar system, the solar battery bank with at least 10-20 kWh energy storage is ideal to use. 

  1. Depth of Discharge

Depth of Discharge or DoD refers to the amount of electricity you utilize from the battery. For instance, a 10.6 kw solar system battery with approximately 10 kWh capacity and 90% discharge capacity lets you utilize energy before you recharge, which keeps a part of the energy unused. Solar batteries should leave some value of energy stored inside every time, otherwise which it would minimize their lifespan significantly. So high DoD depicts a high battery capacity. 

  1. Warranty

Many solar batteries are available in the marketplace, however, every battery is not reliable and fit for your purpose. While choosing solar batteries, you need to select those with high quality and considered mid-range. They exhibit a long lifecycle, ie; cycle multiple times over the lifespan without eliminating the capacity. Check the warranty of the manufacturer and return policy to make sure they safeguard your investment if any concerns occur during installation, operation, etc. 

  1. Lifespan

The lifespan of a solar battery relies on the brand you select and the extent of capacity it can shred with time. To make sure the battery has maximum energy storage and lifespan, ask queries before you purchase. You will require to practice adequate maintenance processes if you wish to maintain the long lifespan of the battery. Protect solar batteries from excessive cold or heat and maintain them at an optimal room temperature. 

Final Thoughts

The aforementioned factors are the common tips you can consider while thinking of a battery installation for your solar panels. The right battery size depends on three specific power needs of the customer— it differs for a 10.6 kW solar system or a 13.2 kW solar system based on the power required. Installation and maintenance of solar panels need expert guidance and services from a reliable provider.
