Coward solar batteries Enable store the energy generated by the solar panels during sunny hours while a the battery is a transforming device chemical energy in electricity, its main characteristic being that it allows electrical recharging. A the battery consists of several accumulatorsso although it looks the same, we are actually talking about different things.
Without accumulators a battery could not work and thanks to solar batteries we can get energy independence of the network, because they allow us we use our energy from the sun even when it is not possible to produce it, such as on cloudy days or at night. Therefore, batteries allow us to make the most of the captured solar energy.
At the same time, the batteries for solar panels offers multiple benefits, such as being able to have the energy that was generated whenever we need it, emit almost no pollution into the environment, and their useful life is long, possibly exceeding 15 years. It is also important to note that below 80% of its capacity a battery continues to function, thus guaranteeing energy storage. Let\’s see below the most significant differences between a battery and a solar battery.
The difference between a solar battery and a battery
We define battery as a source of electrical energy generated by the direct transformation of chemical energy and composed of one or more rechargeable secondary elements. AND battery As the set of batteries or accumulators connected together, forming an integrated unit enclosed in an outer casing that is not intended to be disassembled or opened by the end user. Therefore, a battery consists of several accumulators. And depending on the materials with which a solar energy storage battery is made, there will be different types.
When the lead or lead dioxide in a battery runs out, it wears out, making it necessary to recharge it by passing an electric current from the positive plate to the negative plate, using an alternator or dynamo, or by connecting it directly to the electric current as so that lead sulfate decomposes again into lead on the negative plate, and on the positive to lead dioxide. The the fundamental difference between a battery and an accumulator is that the latter is a cell that stores energy through an electrochemical process and the battery is the assembly of these cells to reach the necessary voltages.
Types of batteries for solar panels
As I commented before, depending on the materials they are made of, there are different types of batteries. for solar energy storage:
Monobloc batteries
The most common, recommended and economical model for use in small and medium power solar installations. They are indicated for the use of simple electrical appliances without a motor (lights, microwave oven, television…). It is about battery high performance for self-consumption solar installations. These types of batteries can have 3 or 6 internal cells or batteries of 2V each, connected to each other forming a single 6V, respectively 12V block. The accumulators of these monobloc batteries are made of lead and electrolyte. Regarding the capacities of these batteries, it should be noted that there are all kinds of options: from <100Ah to 800Ah.
Its big advantage over open lead acid is that it lasts longer. Although the characteristics of these batteries are modified by the use made and the intensity of the discharge, the life cycles of monobloc batteries can be summarized as follows:
- Monobloc gel batteries > +1100 charging cycles
- Monobloc AGM batteries > +500 charging cycles
- Open monobloc lead acid batteries > +350 charge cycles
stationary batteries
Ideal for photovoltaic installations of medium and large consumption, They offer a useful life of almost 20 years due to the fact that the lead plate inside them is tubular and has more lead than monoblock batteries, which have a flat plate. They provide high resistance for continuous charge-discharge cycles.
Like monobloc batteries exist different types of stationary batteries depending on storage capacity and durability, with acid lead and open gel being the most affordable. They are recommended for its use in homes, farms or daily use facilitieswhere the consumption that is made is previously known.
lithium batteries
They offer a high durability and low maintenance. sonny most profitable in the long run due to its greater loading and unloading depth (almost 90% of its capacity). Among the characteristics, its smaller dimensions are noteworthy. Unlike conventional batteries, this type of battery offers a integrated intelligent management and last 6500 charging cycles.
Coward lithium batteries they can be classify according to their voltage. In this way we differentiate between low voltage (LV) and high voltage (HV) batteries.
Thanks to the photovoltaic installations in P.O.W we offer you the opportunity to travel solar panels for self-consumption with or without storage. You choose the project that best suits your needs, but you have the support of the team with vast experience on the national stage.
