LiFePO4 battery is a relatively new contender in the stand-alone solar photovoltaic (PV) applications industry whose benefits for solar energy storage is unrivaled. We will elaborate what are the specific benefits as LiFePO4 are more efficient, effective, durable and consistent than its competitors for solar energy storage.
In one of our previous posts, we talked about why are LiFePO4 batteries the best for solar energy storage. In that post, we wrote about technical issues and how experts and scientists measured LiFePO4 against other batteries. Now we will talk about the benefits themselves in more detail, in order to explain just why this battery is fantastic for governments, companies and institutions - basically anybody who would use it for stand-alone solar photovoltaic (PV) applications.
Challenges for batteries
Historically, batteries are a promising storage technology for stationary applications because of their maturity, the simplicity with which they are designed and installed compared to other technologies. Yet they have a tradition of harming the environment (albeit significantly lower than any competing technology), along with having the chronic issue of properties such as the cycle life, power and energy densities, efficiencies and the costs.
Usually one property would be well developed while others lagged, creating an imperfect product with many issues. Batteries who would last long would waste a lot of energy, or vice versa, they would be extremely efficient but have a very short life-span. Or they could have a low capacity for storage or take forever and a day to charge. These were all favorite citations of solar energy skeptics, especially the stand-alone solar photovoltaic (PV) applications.
They argued that innovation was lagging and that prices were too high, yet the recent decade has rebuffed this vocal point with a long track record of success’. From unprecedented price drops to a sprawling cohort of startups and multinationals who innovated every component of the solar energy industry.
Few aspects of the industry have been under such scrutiny as stand-alone solar photovoltaic (PV) applications. Their immense potential is on a steady course to revolutionize the way people consume energy and change the life of every society on our planet.
This urgency makes the quest for finding effective, efficient and durable batteries a crucial endeavor for the sustainability of the global economy and the ever more connecting societies. It is our firm belief, that the debate on which batteries are the best and whose benefits outweigh any challenges, is settled by the introduction of LiFePO4 to PV applications.
Specifics By now, it is common knowledge that these batteries are lightweight, have a low self-discharge, with a broad discharge temperature frame of -20°C to 60°C, require low maintenance, have comparably high energy density with potential for even higher capacity, and they are scalable. When compared to other battery types for PV applications, LiFePO4 batteries have a relatively low energy density with 90 – 120 Wh/kg, yet they offer quite high capacity, longer life cycles of 1000-2000 cycles, constant discharge voltage of 2.8V/ cell and charge times of maximum 1 hour. No wonder that LiFePO4 batteries are the major battery type of interest for the solar PV industry.
In essence, LiFePO4 batteries are:
• Practical - low energy density yet high capacity • Consistent – with constant discharge voltage of 2.8V/ cell • Efficient – with charge times of maximum 1 hour and, of course, they are resilient, with a long life cycle of more than 2000 cycles.
Therefore, if one is looking for not only efficiency but also effectiveness, set in a practical manner, which can last longer and take only an hour to charge, one needs not to look further. In order to seal the deal, recent developments suggest that in the future prices will go down and make this battery affordable to just about anyone. For PV application, LiFePO4 is like no other.
Conclusion LiFePO4 batteries are lightweight, versatile and eco-friendly with a long lifespan and a fast recharge rate. They can withstand cold, heat, collision, and mishandling during charging and are capable of discharging without the risk of combustion.
