Questions like “is it possible to gain complete energy independence?” or “how solar batteries work?” bump in our section a lot. So here, we have summoned up a solar battery guide to answer most about the solar battery—their working and how they are actually helpful to outbeat blackouts with stored solar energy
Depending on the typical national power suppliers for energy to operate the places, it may cause discrepancy sometimes—although, the established regions have come out to be proficient in being constantly provided with energy to residential and commercial areas—in most of the under-developing regions, minor to major power issues are still common; i.e. power outbreaks, load shedding, and blackouts, etc.
To tackle the common blackouts, and load shedding issues, solar panel systems are extremely helpful. The energy stored in the battery packs being generated through the solar plates is helpful in beating this hassle. Here, we will discuss how solar panels are efficient in storing energy in battery packs.
Mainly, solar panels have the task of generating energy and transferring it to the charge controller or solar inverter (depending on the solar panel system). There are different sorts of PV systems that are installed from residential to commercial level places with different output purposes. These are;
Off-grid solar panel systems are energy independent from the grid, mostly they are used when the utility grid is not accessible (no power supply, in the range). In the broad daylight, they provide energy from the direct production from the sun radiations and they send excess energy generated to batteries.
Sun rays fall on the solar plates, semi conductor in them has free electrons that are pushed because of these radiations—this way energy is generated within the solar panels and is transferred ahead.
Whilst the installation of a solar panel system, the batteries must be included along with it, depending on the capacity of the PV system. In this manner, a solar solution expert (MaxPower) is helpful—anyways once you get the right battery pack connected to the solar power system—now, you can store excess solar energy rather than typically depositing it to the grid. When the solar plates are producing more energy than consuming ratio, this energy is used to charge the battery.
At the times, when the plates are not getting any sunlight, or producing solar energy—the system draws power from the battery to operate standard appliances. This way, with the help of solar batteries, a place remains inbound of electricity without even being connected to the utility grid.
Generally, there are two sorts of batteries used with the solar system;
Here, we have described the general differences between the lead-acid and lithium batteries, their types, uses, pros & cons and other information as well.
The lead acid batteries are distinctly in use for than one and a half century. It was the first type of rechargeable battery and still in common industry but with refined structure and efficiency. For the off-grid solar setups, they are one of the widely used batteries.
Composition & Structure
The negative electrode of the batteries is made of spongy or porous lead. On the other hand, the positive electrode is made lead oxide—the electrodes are submerged in an electrolytic solution. The solution mainly contains sulfuric acid and water.
In the lead acid battery types, they have further two more categories;
The flooded lead acid batteries are also known as wet lead acid batteries—these have caps on the top of the cell compartments that are used to fill distilled water in them.
The sealed lead-acid batteries are totally sealed with no need of refilling distilled water or electrolytic solution. They have limited amount of electrolytes that are absorbed—in a plate separator or formed into a gel.
There are typically two sorts of sealed-lead acid batteries;
The composition of AGM batteries consists of a same chemical base of a lead-acid battery but the positive and negative plates are separated with an absorbent glass mat. The AGM is responsible for the absorption and holding of the battery’s acid to prevent free-flowing. The plastic case is completely sealed, thus making the AGM batteries completely compressed under pressure.
The gel mat lead-acid is the same chemistry-based lead acid battery but a valve regulated one—electrolyte in this battery has a pre-determined quantity, with a typical solution of sulphuric acid and silica fumes.
This is extremely helpful in releasing internal heat and cooling the battery temperature.
The sealed lead-acid batteries have these drawbacks as well;
The lead-acid batteries are likewise used for;
Lithium batteries have hit the market in the early 70s. They are the newest form of renewable energy storage keeping with the ordinary audiences. They are the most expensive one thus, are not keenly in use for the larger scale, but some keen enthusiasts still prefer them for the solar system.
These mainly have applications in laptops and cellphones. These batteries have characteristics as;
