How does a solar power system work?

A solar module is made up of a group of photovoltaic cells. They consist of 2 layers of silicon wafers which become positively and negatively charged when sunlight hits them. The charge created flows through a circuit of small wires connected to the wafers.

The PV modules generate Direct Current (DC) electricity and send it to the solar power inverter. The inverter transforms the DC power from the modules into Alternating Current (AC) electricity and feeds it back to the meter, ready to be used in the house or exported back into the grid/power poles.

When you buy a solar system, the government pays you an incentive for every unit of energy (kWh) that your system produces. And they do it until the end of the yaear 2030.

But for systems up to 100kW (a typical residential system has 5kW), instead of keeping track of your energy production every month, they calculate how much you are expected to produce, based on the size of your solar system, and pay you the whole amount upfront.

Solar hot water systems, sometimes called solar thermal systems, use the direct heat from the sun to heat water, whereas solar photovoltaics “PV” uses sunlight to produce electricity. They are two very different types of technology. Both solar technologies use panels to collect the suns energy. Solar hot water panels have black copper pipes running through them filled with water. Solar photovoltaic panels generally have silicon cells. It is not practical to have one panel to do both jobs.

The payback on a solar system can vary across the country, depending on the local price of electricity, the local amount of sunshine and the electricity usage pattern in the home or business where the system is installed. In general, the more the electricity that is used on-site and not exported to the grid for a low-feed in tariff, the quicker the payback period.

Nowadays, the payback for many solar systems ranges from 3 to 7 years, depending on the above variables. That’s why it is important to get reliable, high-quality equipment installed, as the solar system owner only starts to earn a real income from their system after they paid off the initial investment.

The most considered benefit of installing a Solar Power System is financial. Once installed, a solar system produces electricity from the sun for free. A kilowatt-hour of electricity used from the Solar System is a kilowatt-hour of electricity that does not need to be bought from an electricity retailer. The more electricity that can be used from the solar system and therefore not paid for from the grid, the more money will be saved. As electricity prices increase over time, the greater the financial benefit of having solar becomes.

Feed-in tariffs (FIT) are a defined payment for the electricity you generate from your solar PV system that is sent back to the grid. They vary based on State guidelines and also between electricity retailers. We recommend shopping around between retailers to determine the best available FIT rate for you.

Every watt of electricity generated by your solar power system and used by you directly in your house will save you money, as you do not have to buy this electricity from your electricity retailer.

Therefore, it makes sense to use as much power as possible during the day, when the panels are generating power e.g. by turning on pool filters, dishwashers and washing machines when the sun shines brightly.

Most energy providers offer a feed-in tariff, as credit is given to the consumer for any surplus power generated and exported back to the grid.

The amount paid for each kilowatt-hour of electricity can vary between energy retailers. Contact local energy retailers in your area, they will be only too willing to sign you up to an energy plan.

Yes, the solar power system rebate is given to the physical property address and not the individual. If you are a multiple property owner, then you can avail of the solar rebate for all your properties if they fall into the criteria as laid down by the government.

It is very important to get a solar advisor to come to your house and investigate your particular circumstances. It’s not sufficient to get a final quote over the internet without the company actually having seen your house. Would you accept a quote to install a new stairway or a new bathroom in your house via a call centre – without a site visit? If the quoting company cannot give you a free site inspection, then you are not their priority – not now and not when they install your system. For some in the solar industry that follow the internet and google map sales model, it is all about sales volume – not necessarily about solar sales service.

How does a residential solar system work?

A residential solar system converts sunlight into electricity using photovoltaic panels. The DC power generated is sent to an inverter, which converts it to AC electricity for home use. Any excess energy can be stored in a battery or exported to the grid.

Savings depend on your energy usage, system size, electricity rates, and sunlight exposure. Most homeowners reduce their energy bills by 40–80%, and some achieve even higher savings with battery storage.

The ideal system size depends on:

  • Your daily electricity consumption

  • Roof space and orientation

  • Number of family members

  • Whether you use electric appliances, heating or cooling
    Connect Energy performs a site inspection to recommend the best-fit system.

Yes. Solar panels still generate electricity during cloudy or overcast weather, though at reduced efficiency. Modern high-efficiency panels ensure steady performance even in variable conditions.

A battery is optional. Without a battery, surplus energy goes to the grid. With a battery, you can store unused solar power and use it at night or during outages. A solar + battery setup increases energy independence.

Premium solar panels typically last 25–30 years, with many maintaining strong performance well beyond their warranty period. Inverters usually last 10–12 years and may need replacement once during the lifespan of the system.

Solar requires minimal maintenance. Cleaning panels once or twice a year and scheduling periodic inspections ensures optimal efficiency. Connect Energy provides ongoing maintenance and support packages.

Most Australian homeowners qualify for STC solar rebates, which significantly reduce the upfront cost of a solar installation. Eligibility depends on your system size and location.

Yes. Homes with solar installations are often valued higher due to reduced energy costs and long-term savings for the new owner.

Most residential solar installations are completed within 1 day. Larger systems or complex roofs may take slightly longer.

Yes. Connect Energy systems include smart monitoring apps that allow you to track real-time production, consumption, battery levels, and system efficiency from your phone.

In most cases, no. Standard rooftop solar installations are exempt. However, Connect Energy handles all necessary paperwork if approval is required.

If you have a battery or hybrid inverter, you can run essential appliances during outages. Standard grid-tied systems shut off for safety reasons until power is restored.

How much can a business save with commercial solar?

Savings depend on system size, energy usage and sunlight conditions, but most businesses reduce their electricity bills by 40% to 80% after switching to solar. With battery storage, savings can be even higher because more power is used on-site instead of being sent back to the grid.

Most commercial installations are completed within 2 to 8 weeks, depending on system size, roof structure, and grid approval timelines. Connect Energy manages the entire process from engineering and approvals to installation and commissioning.

A standard grid-connected solar system does not provide backup power during outages.
However, when paired with battery storage, a commercial system can supply electricity even when the grid is down — creating true energy independence.

What is a solar battery storage system?

A solar battery storage system stores excess electricity generated by solar panels during the day so it can be used later, at night, or during a power outage. This helps households and businesses maximise self-consumption and reduce reliance on the grid.

Savings depend on system size, electricity usage, and solar generation. On average, households can reduce grid electricity consumption by 30–70%, which lowers electricity bills and protects against rising energy costs.

Yes. Some batteries can charge from the electricity grid during off-peak hours and discharge when rates are higher, offering cost savings even without solar panels. However, pairing with solar maximizes financial and environmental benefits.

Most modern lithium-ion solar batteries last 10–15 years, with performance warranties guaranteeing consistent energy storage during that period. Proper maintenance ensures optimal operation and longevity.

Yes. When configured for backup, battery systems automatically supply electricity to essential appliances during outages, keeping fridges, lighting, security systems, and medical devices operational.

Battery sizing depends on your energy consumption patterns, solar panel output, and backup requirements. Connect Energy performs a detailed assessment to recommend the ideal battery capacity for your home or business.

Costs vary based on capacity, technology, and installation complexity. Many customers find the long-term savings and increased self-consumption offset the initial investment. Flexible financing options are often available.

Lithium-ion batteries require minimal maintenance. Periodic performance checks and software updates ensure efficiency, safety, and long-term reliability. Connect Energy offers monitoring and maintenance services to keep your system performing optimally.

Can I charge my electric vehicle directly from solar panels?

Yes. Solar panels can supply electricity directly to an EV charging station. Any excess energy can be stored in a home battery for use when solar generation is low or during the night.

Charging your EV with solar electricity significantly reduces reliance on the grid. Savings depend on your solar system size, driving habits, and electricity rates, but most homeowners see substantial reductions in energy bills over time.

A battery is optional but recommended. Without a battery, your EV will only charge when the sun is shining. A battery allows you to store excess solar energy and charge your vehicle at any time, including evenings or during cloudy days.
