Solar PV Systems

In the sun-soaked city of Perth, harnessing solar energy is a lifestyle many are embracing as we shift towards sustainability and efficiency. At Middle Swan Solar, we specialise in providing top-tier solar photovoltaic (PV) systems designed to meet the unique energy needs of Perth residents.

This effective solar system in Perth can help control how much energy you pay for in your energy bills, while still allowing your property to get the right amount of power it needs. While the initial cost may be pricey, you will end up saving a small fortune on your electricity bill in the long run. Ultimately, there are no drawbacks to having a solar PV system installed.

What is a Solar PV System?

A solar photovoltaic system, commonly referred to as a solar PV system, is a power system designed to convert sunlight into electrical energy. This transformation is achieved through solar panels made up of photovoltaic cells. These cells capture sunlight and convert it into direct current (DC) electricity, which is then converted into usable alternating current (AC) electricity via an inverter.

How It Works

Photon Absorption: Photons from sunlight hit the PV cells and free electrons, creating a DC flow.

Conversion to AC: A solar inverter then converts the DC to AC, as this energy can be used by appliances and grid export.

Integration: The electricity generated can either be used on-site, stored in batteries for future use or exported to the grid. In most states, you may even be compensated for electricity added to the national grid, making it a great investment. However, this varies by state.

A fully functional solar PV system comprises several key components:

Solar Panels: These are essentially an array of PV cells that have the ability to produce DC electricity when exposed to direct sunlight.

Solar Inverters: Inverters are used to convert DC electricity into AC electricity. Additionally, they provide monitoring and grid-safety functions, playing an integral role in solar energy production.

Solar Batteries: This is an electrical energy storage device that captures excess electricity produced by solar panels. This electricity can then be used later, providing a source of backup power when there is no sunlight available.

Mounting Systems: A mounting system is simply the structural framework that secures solar panels to the roof or ground.

Monitoring Systems: Finally, a monitoring system is hardware and software that tracks a PV system’s real-time performance. It displays energy production and consumption, battery state, and any system faults, enabling you to optimise energy output.

How Much Do PV Panels Cost?

It’s no secret that PV panels can cost a lot. However, when you take into account just how much money you will save on your electricity bill, the initial price tag suddenly doesn’t seem so excessive.

For a complete small system, you can expect to pay anywhere between $3,000 and $6,000. This is suitable for small residential solar PV systems. A medium system costs between $5,000 and $11,000. Finally, a large system can cost anywhere between $8,000 and $18,000.

It is important to note that this cost includes the PV panels (which account for anywhere between 20% to 40%), the inverter (10% to 20%), mounting/wiring/electrical work (10% to 20%) and labour/permits/design/testing (20% to 35%).

Additionally, you can pay for an optional battery, which adds anywhere between $6,000 and $10,000 to your total cost, depending on the size of the battery you need.

Types of Solar PV Systems

Grid-Tied Systems

These systems are connected to the local power grid and can offset your energy costs. Excess energy generated can be fed back into the grid, often resulting in credit from your energy provider.

Off-Grid Solar Systems

Completely independent from the power grid, these systems rely on batteries for energy storage, ideal for remote locations where grid connectivity is not feasible.

Hybrid Systems

These systems combine the best of both worlds, incorporating battery storage with grid connectivity for increased energy independence and reliability.

Solar PV Output

The total PV output of your solar system depends on its rated capacity, how much sun the system receives, as well as any real-world losses, such as shade and wiring/inverter inefficiency.

This is exactly why the position of your PV panels, the quality of the system, and how it is installed are so important. By choosing Middle Swan Solar, you can rest assured that everything will be properly taken care of. Your panels will be effectively and efficiently installed, resulting in optimal energy production and system longevity.
