Lithium solar batteries encompass a variety of lithium-based battery chemistries, such as lithium ion and lithium iron phosphate (LFP). The latter are considered to be the best lithium batteries for solar systems. LFPs are known for a high cell density, which means they are very compact. What’s more, they last even longer than lithium ion batteries because of the electrolyte's properties. Well, it’s easy to see why a lithium solar battery, especially LFP one, is a go-for option when it comes to arranging a reliable energy storage.
Main advantages of lithium solar batteries
High Cell Density
Cell density describes how much power is stored within a particular space. The higher the density, the longer the battery can run. Lithium iron phosphate batteries tend to be slightly larger than lithium ion batteries, but are still very compact. This is offset by the fact that LFPs are less volatile, meaning they are highly unlikely to overheat or catch fire. This is particularly important in higher temperature environments, and situations where a high voltage is needed.
Lithium batteries boast longer battery life: up to six times the battery life of a conventional lead-acid battery. The secret behind it is the chemistry properties. More life cycles mean less expenses and a lesser risk that your battery will die at the wrong moment. Lithium solar batteries are also maintenance-free, so you can choose practically any place in your house to install them: attics, crawl spaces, outbuildings, or other spaces that are hardly ever accessed.
In the end, going solar is about environmental responsibility. While solar panels themselves are mostly earth-friendly, batteries are not. Luckily, solar lithium batteries, especially lithium iron phosphate ones, are not considered toxic. The materials they contain – iron, graphite and copper – are easy to recycle. What’s more, some batteries are already made from recycled materials.
The non-combustible nature of lithium batteries as well as their long lifespan make them less harmful for the environment than, say, lead-acid batteries. Lithium batteries don’t overheat, therefore, if they’re not properly disposed of, they are safer in landfills than lead-acids. Moreover, they won’t be replaced as often as lead-acid counterparts, which means less energy will be used to process materials.
How to size lithium battery for solar PV system
When sizing a lithium battery for solar storage, think about what you want to do with it. For instance, if you live in an area where power outages are frequent, and you need energy storage as a backup, then calculate your daily energy needs by using electrical meters, looking at your recent electricity bills or multiplying the power ratings of your household appliances by their hours in use one by one. If you want to run the battery for one day or more, multiply your daily needs by the number of days you plan to use your battery.
