All About Solar Batteries

Everything to know About Solar Batteries

Battery your way to grid independency

A totally grid independent sustainable green energy solution is is made possible only by sufficient battery backup.
Let’s have a deep dive into all aspects that make a solar batteries.

What is a Solar Battery?

A battery is a device which converts electrical energy into chemical energy and vice versa. Many varieties of batteries exist as per needs of system. Lets have a look at some batteries important in solar system.

Common Terms Related to Solar Inveter

Strings

Shading

Blackout

Maximum Power Point Tracking

Energy Production

Efficiency

Temperature Coeffecient

Solar panels connected in series are called “strings”.

Strings of solar panels that are obstructed from sunlight by tree, building shadow or any hurdle.

Electricity grid power outage.

Circuit that tracks point of panel where product of voltage and current generated is the highest.

Log of data in kwh that records solar electricity produced by installed panels

Overall percentage the depicts the performance of panels in comparison to others. It is the percentage conversion of power from sun to electricity.

The value which measures deterioration in output as temperature of panel is increased.

How Does a Lead Acid Battery Work?

During charging of battery, current is passed through it which causes some chemical changes inside the battery. This chemical changes absorb energy during their formation. A typical Lead Acid Battery consists of Lead Peroxide (PbO2) that works as positive plate . The negative plate is made of pure lead in soft sponge condition. Electrolyte is made of Dilute Sulfuric Acid (H2SO4)

Type of lead acid batteries

Traditional Flat Plate Lead Acid Battery

Traditional widely available version of lead acid battery. It is a lead-acid battery design with flat electrodes.

Most widely used solar inverter in Australia

Tubular Batteries

Advanced lead-acid batteries with tubular positive plates, designed for better durability and efficiency.

Each panel is individually managed.
Shading of individual panels does not drop total system efficiency.
Provide Individual panel data.
Allows for more scalability.
Better identification and rectification of individual panel issues.
Increased system cost because of increased hardware.

Sealed Lead Acid (AGM/Gel)

Includes Absorbent Glass Mat (AGM) and Gel batteries, which are maintenance-free.

It is the most flexible inverter allowing solar, grid and battery backup to all work together.
Battery charging and management capabilities.
More input or output options than any other configuration.
Availability of backup power in case of grid outage.
More Costly than on grid option.
Environmental impact because of battery backup.

Cost of Solar Dream

Now you have a grasp of available options in solar panels so let’s address the elephant in the room, How much do they cost?

Factors effecting cost of system

To estimate your solar system cost

Specify energy demand / solar system size

Demand can be estimated from annual energy consumption from your electricity bills, use the calculator to get daily energy demand and suggested systems that meet your needs.

Choose your panel tier.

Specify the dimensions, alignment and angle of roof or specify the dimension of ground location proposed for installation.
