Or breaking the web to get your hands on an affordable solar battery that is not only cost-effective but also very durable and reliable over long durations.
Buying Guide Of BEST BATTERY FOR SOLAR PANEL – Infographics
For those looking for an effective and efficient solar battery, you need to mind a few things that make the process of finding the desired product easier and more effective.
But for that purpose, the consumers must have the required information and technical expertise to recognize worthy and cost-effective solar batteries.
This is not an easy task particularly when you are in a rush.
You have to ensure that the product description is fully understood and you can distinguish between 300 Ah or 100 Ah or BMS or non-BMS batteries and many other features and specs counting in the performance.
To better understand these essential requirements, let’s go through the necessary things that should be considered before buying the best solar battery for solar panels.
1. Things To Consider Before Buying The Best Battery For Solar Panel:
Some of the things that should be given attention to are battery type and capacity.
On the other hand, when it comes to budget, I believe that none of you here will underestimate its importance in buying your desired product.
If you are connected to grid power having the minimum battery capacity may be able to get your job done but when off the grid, having a massive capacity is a requirement.
Being able to find your desired solar battery is although tiring but not an impossible task.
Here are some crucial tips and tricks that will help you in getting your hands on the best battery for solar panels.
If you’re looking, for the best solar battery for solar panels, let’s review the necessary things, features, and specs that are our recommendations for the best purchases.
Are you ready, let’s get started!
1. Battery Type:
The foremost requirement when selecting the solar or any other battery is to determine what type of battery cells you need.
There are many types of batteries that are available in the market and have dedicated series that are available in all budget ranges, all capacities, and all types of construction materials.
The common battery types used for solar batteries are:
- Lithium Batteries
- Sealed Lead Acid Batteries
- Flooded Batteries
- Deep Cycle Batteries
Lithium batteries are further of various types such as
- Lithium-ion Batteries
- Lithium Polymer Batteries
- Nickel Cobalt Manganese Batteries
Lithium batteries are the most widely used solar batteries as well as other types that include both indoor and outdoor batteries.
Lithium batteries are preferred over other types because of the following reasons;
- Longer lifespan
- Slower drainage
- Enhanced depth of discharge
- Built-in BMS (Battery Management System)
- Wide range of applications
- Increased Battery Endurance
- Higher life cycles.
Sealed lead acid batteries are extensively used after lithium batteries and have better features and specs than flooded or other types of batteries.
These SLA batteries are quite closer to lithium batteries in performance and maintenance.
Sealed lead acid batteries don’t have dedicated BMS as lithium-ion batteries but have fewer maintenance demands than flooded batteries.
Although this type of solar battery doesn’t mind the monitoring needs but keeping track of your battery operation is always a wise idea.
Therefore, carefully choose the battery type before looking for specific models and choose the one that matches your budget and features.
2. Battery Capacity:
After deciding on the type of battery you have to mind the capacity that your upcoming battery has.
Deciding on the battery capacity is dependent upon your need including outdoor or indoor settings, utility power availability, and energy conversion efficiency.
There are various capacity batteries available in the market and one can have literally any capacity he or she may desire.
You can start with the 25Ah solar batteries that are more inclined towards outdoor use and go as much as 400 amp hour that are massive residential units acting as home standby power backup kits.
The best battery capacity is not the highest nor the lowest one but rather the most suitable one for you.
The suitable battery capacity is the amount you need from your battery at the given moment. If you are outdoors being away from your home, having a 25 to 100-amp-hour battery will be suitable for you.
While at your home where power outages are frequent and power trips under horrid climates are common then massive battery capacity kits with 300 or 400 Ah power may be your necessity.
The battery capacity is relevant to your power needs and how many heavy-duty appliances you have at your disposal.
If you have to power many high-wattage appliances like 2 or 3 16,000 BTU AC units, home heating systems, microwaves, refrigerators, freezers, kitchen utilities and many other household appliances demanding higher power output then having high-capacity batteries is mandatory.
But if you have a medium-sized household with a few heavy-duty appliances like a 12,000 BTU AC unit and other mid-range appliances, a single 100 Ah solar battery will be sufficient for you to power your household appliances when not running on the grid power supply.
3. Input Voltage:
The input voltage may seem of secondary importance while studying the product description but when it comes to solar batteries you have to pay attention to it.
This is because most solar batteries require a 12V DC input supply for connecting with the solar panels.
Although other voltage can be used in that case, you would have to use certain connectors or adapters to hook up your solar batteries with the solar panels.
There are 48V solar batteries also abundant in the market but these 48V DC voltages are designed specifically for residential units where you have to use the standard 48V input at-home standby solar kits.
FAQs (Frequently Asked Questions)
1. Which Batteries Are Best For Solar Panels?
Lithium Solar Batteries are the best for solar panels and this includes both Lithium-ion and LiFePO4 batteries. Lithium batteries are efficient, faster, and have a longer lifespan.
There are also no maintenance batteries and pose minimal resistance to the current flow.
2. Can You Use Any Battery For Solar Panel?
You can just hook up any battery with your solar panel as it needs to have a specific charge controller, connecter, and dedicated power outlets for a successful connection.
Simply any 12V DC battery can be connected with solar panels. Typically, LiFePO4, Lithium-ion, Sealed Lead Acid, and NMC batteries are used for solar panels.
3. How Many Batteries Would You Need For A Solar Panel?
The straightforward answer to this depends upon your battery capacity and power requirements. If you have the average daily output requirement of 50Ah, then having a battery twice the output capacity is the best cutoff.
This is because even the best solar batteries will give you 50% usable storage efficiency and therefore having 2X capacity will be the standard.
4. What Is The Cost Of A Battery For Solar Panels?
Solar batteries cost can range from the pocket-friendly price tag of 200 USD to high-end premium units of about 15,000 USD excluding the installation charges.
Lithium Batteries are the most expensive but most efficient, longest-lasting, and best-performing batteries.
5. What Is The Longest Lasting Solar Battery?
Lithium solar batteries, without a doubt, are the longest-lasting solar batteries with an average lifespan of about 10 years.
These batteries are low or no maintenance batteries and therefore, even careless customers can last well enough for 10 or 12 years with Lithium Batteries.
