Choosing suitable solar panels is of high importance. Many factors are taken into attention before making a purchase. Batteries are one of the most essential elements of off-grid solar systems for a backup power storage station on rainy/cloudy days or at night. Firstly, you need to understand what you want to get out of your battery.
Eco Green Energy prepared a short reference about the most popular batteries types to help you pick the right one.
GEL batteries
Gel battery consists of silica gel network and gel sulfuric acid as electrolyte. The electrolyte stays in the colloidal state, filling between the membrane and the positive and negative poles. The gel surrounds the sulfuric acid electrolyte and does not flow out. That makes gel batteries very resistant to vibrations.
Furthermore, GEL batteries are of long usage life and safer for utilization. To their advantage, we can also include a deep discharge cycle. It makes them appropriate for all emergency applications and testing solar projects.
Additionally, low discharge ampere mode is one of the characteristics of the GEL batteries. They can be completely discharged and do not require any particular maintenance. Their recharge is slow because the battery is not adapted to high charge and discharge currents.
It is worth mentioning that all Eco Green Energy GEL Batteries comply with CE and UL certification with a warranty of two years. These products are suitable for off-grid systems and solar road lights.
Lithium batteries
Nowadays, the application of lithium batteries has increased because of a slight price drop in the recent five years. According to Statista, the lithium batteries market will grow at a GACR of 14.6 percent in 2026.
There are three main types of lithium batteries: ternary, manganate, and iron phosphate. The last type can provide the ideal solutions for the renewable energy industry. Low maintenance, stable chemical materials, activity status monitoring, and lightweight increase convenience on installation and transport.
Another significant advantage of lithium batteries is the possibility to utilize all the energy stored. Moreover, they recharge twice as fast as traditional batteries.
In fact, lithium batteries are suitable for most applications such as electric vehicles, solar storage and installations, remote monitoring, buggies, and more.
GEL VS Lithium batteries – what to choose
To conclude this analysis, we gathered all data into the table above:
– Lithium batteries are fitting for a much broad temperature range.
– Normal storage or charging temperature should be 0℃. Or the charge will be failed for both types.
– The weight of the GEL battery is equal to two Lithium batteries.
– Both GEL and Lithium batteries are safe for application and transport. GEL batteries are with stable chemical effect inside. Lithium – use the best BMS (Battery Management System) to protect the battery.
– Gel batteries are cheaper than Lithium ones at 50% of the price.
The EGE batteries are of the best quality on the market. Moreover, our products comply with strict standards of CE UN38.3, UL1642 & IEC62133 certifications. We also guarantee Built-in Circuit Protection.
Our Advice
Eco Green Energy suggests choosing the batteries according to your purpose and within the most relevant price. GEL batteries are the best for testing or less expensive solar projects. Lithium batteries are good for long-time installation and help avoid frequent substitution.
