Residential solar and battery system Sydney

Many consumers prefer to use a solar battery to store energy for later use and keep appliances running. Residential solar and battery system Sydney are two inseparable parts of a solar system for the households, and effectively, can be used for power storing. Although the houses in Sydney are developing the use of solar systems, batteries becomes important for these consumers.

On top of this fact, electricity use has grown by %19 in just three years, and solar panels become an attractive alternative for these consumers.

Residential solar and battery system in Sydney

Both residential and commercial solar panel systems are demanding in the market and due to the number of houses, residential solar systems almost is the winner of this competition. Today, over 90.000 households use solar panel systems for power generating and supplying electronic appliances.

As it cores, residential solar and battery system Sydney place in high demand compared to commercial panels, and the households think to reduce reliance on grid electricity.

1. Lead-acid batteries

This is the cheapest type of batteries can be used for residential solar panels. This battery has a shorter lifespan and depth-of-discharge is lower compared to other storage options. It’s recommended to use lead-acid batteries to the depth-of-discharge lower than 50% because a higher percentage of use can negatively affect their lifespan.

• Li-ion batteries

This storage solution has higher prices than other options but is smaller and lightweight compared to lead-acid batteries. These types of batteries are also able to easily handle the deep discharge of 80% or more. This means they have a higher usable capacity.

• Saltwater batteries

Despite traditional lithium-ion batteries which use the element lithium as its primary ingredient for electricity conducting, saltwater batteries’ main ingredient is sodium which is the same element that has been found in salt. This makes saltwater batteries easier to recycle. The main flaw of saltwater batteries is lower energy density and cost higher.

So, when considering the residential solar and battery system in Sydeny, select the type of battery depending on the level of electricity use.

Can I prepare a solar panel system without a battery?

You can use the solar panel without a battery, but you almost lose over 50% of your system power production. Without batteries, the power generated by the panel will not store and must be used up as it is generated. Also, it will go straight back into the grid.

The extra energy made out of solar panels can be sold to the National Grid, through its Smart Export Guarantee. This is a government-backed initiative that requires some energy suppliers to pay small-scale generators for low-carbon electricity.

Electricity is more expensive than what you have to get via the SEG initiative, the household saves money if she/he simply stores excess energy in the solar battery for later. The average three-bedroom house will generate 1.492 kWh of spare electricity power year.

So, you can prepare a solar panel system without a battery but it’s recommended to have a battery for energy storing. To know details about residential solar and battery system Sydney, contact our sales department.

How to choose a solar battery for the system?

• Battery size

Battery sizes are expressed in kilowatt-hour which is called kWh. This statement in a battery uses as a bank at night or in lowlight conditions when the solar production is not enough for appliances’ power. Smaller batteries can be 2kWh sizing up to 20kWh or even more.

• Energy capacity

The energy capacity is measured in kilowatt-hours, and do not be confused by the difference between kilowatts, measurement of power, kilowatt-hours, and measurement of energy. The battery’s power rating tells you how many appliances your battery can power and which appliances are. Most of the batteries are available on the market and have a continuous power output of around 5 kW.

• Roundtrip efficiency

This is a percentage of electricity put into storage uses later, to put it simply, several kWh of electricity loses when inverting it from direct current to alternating current electricity. How much the roundtrip efficiency is higher, the less energy is lost in the storage process, typically, it’s about 80%.

• Safety

Solar batteries consider very safe and mean the risk of putting a solar battery on the house side and similar to having mobile phones or laptops at home. The solar batteries should meet certain safety requirements to be verified in homes and businesses’ installations. Ensure about the whole requirements in the battery you have chosen.

• Battery lifetime

The battery lifetimes determine by three factors and different metrics; expected throughput, expected years of operation, and expected cycle. The battery life is determined in years while the battery’s throughout likes a car’s mileage warranty. These batteries include a super high cycle life which does not require frequent maintenance or replacement. They still remain functional after thousands of times charged and discharged.
