Explore the Different Types of Solar Systems

Various types of solar power systems available

According to the most recent Clean Energy Australia Report, 310,000 new rooftop solar systems were installed in 2022, collectively reaching a capacity of 2.7 GW, equivalent to the Eraring Power Station in New South Wales.

This indicates a growing acknowledgment of the advantages of solar power, positioning the country as a global leader due to the heightened interest of Australians in solar energy.

The following are some advantages of solar energy that are encouraging more people to use it:

  • 1. Over time, it can result in lower electricity expenses for you.
  • 2. It has the potential to lower national carbon emissions.
  • 3. Employees there face less of a health risk than those employed in the fossil fuel sector.
  • 4. It has little effect on the environment.

There are other advantages to solar energy that can persuade anyone to put a system in their home. However, it's crucial to understand the many kinds of solar systems that are available before installing one.


Different types of solar power systems

1. Portable solar power system

Depending on the individual's circumstances or needs, many methods are available. One of the increasingly popular technologies is the portable solar system.

The name of the system implies that it is appropriate for those who are going on long excursions, such as road trips in vehicles or trains, and need to charge tiny appliances or devices.

Portable systems are suited for use in distant and outdoor environments such as the outback, woodlands, or along the coast. The power stored in these little kits normally ranges from 3W to 120W.

This energy capacity is enough for powering tiny devices, with the primary criterion being the kit's compatibility with the user's individual location.


2. On-grid solar power system

Connecting your system to the national power grid is what on-grid solar, also known as grid-connect, grid-tie, or grid-feed solar, entails.

On-grid is the most common system in Australia, accounting for roughly 95% of all solar installations. This kind does not need the connection of a battery.

The excess solar power generated by the system is sold to the energy retailer, providing the major incentive for homeowners and businesses to choose on-grid solar systems.

Because restrictions change from state to state, it's a good idea to research the state's policy on selling extra power to the electricity retailer. Before installing a system, double-check this.


3. Off-grid solar power system

As the name implies, an off-grid solar system operates independently, not connected to the power grid, providing standalone power for various home or business appliances.

An off-grid solar system gives flexibility for use anywhere, unaffected by the drawbacks of grid connections, such as blackouts, because it is not connected to the main power grid.

For this type of system, a distinct set of components is needed, specifically:

  • Solar panels that capture energy from the sun.
  • Charge controller, which takes care of regulating the energy that flows from the panels to the solar batteries. This is basically a small computer.
  • Solar batteries store the converted energy captured by the panels.
  • Solar inverter, which converts the current from DC power (low voltage) to AC power (high voltage).

The major drawback of an off-grid system is its high cost, nearly three to five times more than an on-grid system. Additionally, the use of batteries for energy storage entails periodic replacements.


4. Hybrid solar power system

Hybrid systems are gaining popularity because they address the major problem of solar battery longevity that is present in other system types.

In general, the "depth of discharge," or the amount of battery drain before recharging, has a substantial impact on a battery's longevity.

When a battery's capacity falls below 20%, it is said to be deeply drained. This is known as deep cycle recharging once it has been recharged.

Deep cycle recharging has an effect on battery life. To address this issue, consider a hybrid system that includes a wind turbine. The interaction of sunshine and wind boosts charging efficiency.
