Solar is one of your greatest options if you want to supply your residence with a renewable source of energy to battle climate change and reduce your utility bills. However, because solar panels can not produce power when the sun is not shining, many homeowners ask if solar PV arrays can provide all the electricity their homes require.

Fortunately, if you have enough solar panels, a solar energy system can entirely power your home. This is typically made available by a local utility company’s net metering programme. Even when the sun is not shining, these systems allow your solar panels to reduce your electricity costs. You can add energy storage to the solar PV system if your town does not have net metering or if you do not wish to depend on the electricity grid at all.

Continue reading to estimate how many panels you need, learn about net metering programmes, evaluate the advantages of battery storage, and analyse the pros and costs of shifting to solar energy.

Can Solar Panels Provide Power for an Entire Home?

This question’s response is more complicated than you may expect. If you install enough solar panels, they can generate all of the power your home requires while the sun is shining.

Unfortunately, solar panels do not create energy during the night, and they generate less electricity on cloudy weather. Therefore, solar panels cannot power your home while the sun is not shining, at least not all on their own.

Nighttime Reliance on Solar Batteries

Installing a solar energy storage system is the only option to power a home solely with solar energy. When you use a solar battery, the extra energy or excess generated by your solar panels during the day is sent to the rechargeable batteries for storage. Then, as the sun sets, your system draws the battery’s energy to power your residence for the duration of the night.

If your primary motivation for shifting to solar is to be more self-sufficient and lower your carbon emissions, then adding energy storage is the most effective approach to achieve these goals.

However, it is not the most economical choice. Solar battery installation normally costs between $4,500 and $18,000, and you may have to instal many batteries to supply all of your home’s energy storage needs. Unless your state mandates net metering, a battery is definitely unnecessary if your primary motivation for choosing solar is saving money.

Can Solar Panels Totally Get Rid of Your Monthly Power Bill?

Even without a solar battery, your solar panels can completely eliminate your monthly electricity expenditures if your utility company supports net metering.

A tied to the grid solar panel system maintains your connection to your utility company’s electricity grid. We’ve already established that solar panels produce the greatest energy when the sun is at its highest, which is also when your home needs the least energy. As a result, it’s likely that the energy produced by your panels will exceed what your house actually needs.

When this occurs, the surplus or excess electricity is fed back into the grid, where it can be used to power additional structures. As a result, the electric business is able to use fewer fossil fuels to power the grid. In addition, you need not worry about anyone else using your solar energy; your home will consume it first. Your home’s surplus power supply is the only thing that is sent to the main grid.

The best thing is that, if your utility provider allows net metering, you will be reimbursed in full or part for every kWh of energy you feed back into the grid. One kilowatt-hour of electricity exported qualifies the consumer to draw one kilowatt-hour of the grid’s energy at a discounted rate. Full retail net metering means you pay nothing for the electricity you generate if your electricity company allows it.

Even if your solar array aren’t able to generate enough energy to completely power your home on their own, you may still be able to get your electric bills down to zero with the help of net metering.

What Exactly Is Net Metering?

Through a mechanism known as solar net metering, ordinary homes and businesses can generate electricity from the sun while still maintaining their connection to the grid. The term “net metering” is used to describe the method through which users of solar panel systems are compensated by their electricity providers. Connecting to the grid allows solar panel owners to sell excess energy to other customers and earn credits.

Net metering is widely used in several nations across the world. Customers can expect to be compensated for their solar power production at a rate comparable to that of traditional grid power. The excess power your solar panels produce will be compensated at the power generation pricing in Australia. For this reason, you’ll pay just for the energy you really use rather than what you could have generated from the sun.

It is important to keep in mind that your home will get the first shipment of energy generated by your solar panels under Net Metering. Then, the surplus power is fed back into the grid when it’s not needed.

Different Solar Net Metering Contracts

In Australia, there are two types of solar energy meters: solar net metering and gross metering.

• When solar energy is used exclusively within a home, only the excess unused energy is fed back into the grid through a process called “net metering.”
• With gross metering, all of the power produced from solar panels is sent out to the grid. In Australia’s warm climate, solar energy is abundant, especially when you have access to massive solar arrays.

Solar panels, also referred to as solar PV arrays, that generate a great deal of electricity are required for both Gross Metering as well as Net Metering.

Does Net Metering Apply in My State?

While solar power is on the rise in Australia, policies concerning financial incentives or Net Metering vary significantly from one state to the next. Unfortunately, Net Metering isn’t available everywhere in Australia. In the states and municipalities listed below, net metering is available.

• Adelaide
• Alice Springs
• Blacktown
• Central Victoria
• Moreland
• Perth
• Townsville

Net metering is sometimes called a feed-in tariff to distinguish it from the former. In some cases, energy service companies may give feed-in tariffs or rebates. Therefore, feed-in tariffs availability varies by state and electricity provider across Australia. If you have excess solar power, you can send it back to the power grid and receive a credit against your electricity bill using this tariff, which operates like Net Metering.

Pros of Using Net Metering

Both households and the environment can reap several benefits from net metering. Installing a solar panel system that is connected to the power grid has many advantages, some of which are listed below.

Lowered Utility Costs

A major incentive for making the switch to solar electricity is the money it can save you. Living in a sunny location can significantly reduce your monthly energy bills. If your panels generate more electricity than you use, you can use Net Metering to make money. The only time you’ll have to pay for electricity is if your consumption exceeds your production. And if your solar panels produce more electricity than you use, you may sell the extra power back to the utility company.

Provide Energy to Multiple Structures

You can instal solar panels or solar panel kits on your house, lodge, garage, shed, or even your car to help reduce your dependence on fossil fuels. Whether you live in an apartment in a city or a collection of outbuildings on a rural farm, you can save money by switching to solar energy.

Lessen Your Impact on the Environment

If you’re concerned about your environmental impact, making the switch to solar electricity can have a significant effect. Becoming more self-reliant is one way you may help save our limited supplies of natural resources. When you switch to solar energy from electric and gas-powered generators, you may find that you become more conscious of your energy use habits.

In Order to Completely Power Your House With Solar Energy, How Many Panels Do You Need?

A typical Australian home requires between sixteen and twenty solar panels to offset their annual energy expenditures. This estimate, however, is derived only from data on energy use in Australian homes as a whole.

The optimal number of panels for your residence will be determined by several factors, including the total amount of energy your household consumes annually, the power rating of each panel, and the efficiency with which the panels can operate in your region.

To learn how many solar PV panels you’ll need to provide electricity for your entire home, follow the simple steps in this guide.

Verify Your Current Power Use

Check your monthly power bills to get a sense of your typical electricity usage. Electricity consumption varies throughout the year due to weather, therefore it is best to look at your bills for a complete year, add up the kilowatt hours of usage for each month, and then divide by 12 to get an annual average.

Determine How Many Daylight Hours Your Region Enjoys

Figuring out how many prime sun hours your location sees each day is the next stage because the final output of such a solar array is partially controlled by the amount of direct sunlight it collects each day.

Power Output of Your Solar Panels

Next, you should look up the wattage of every solar panel you’re considering buying to see how much power they can produce. Different panels have different wattages, which indicate how much energy they produce. Panels with a lower power rating will require additional panels to meet your household’s energy needs.

The total power output of a solar panel array is expressed as the sum of the individual panel’s wattages, which often ranges into the thousands of watts. Kilowatts (kW) are a convenient shorthand for measuring power because they equal 1,000 watts (W). 4.8 kW is the total output of 16 300-watt solar panels, as 1 kW is equal to 1,000 watts.

A 4.8 kilowatt solar panel system, in ideal conditions, can generate 4.8 kWh of electricity in in one hour. The system’s actual energy output will be lower.

Try to Estimate How Many Panels You’ll Need

Let’s assume your monthly energy use is a typical 893 kWh. Then, suppose you live somewhere that only gets four hours of direct sunlight per day. If you take 120 and multiply it by 30, you get the average amount of daylight hours per month your home receives from the sun. If you installed a 1 kilowatt solar array on your roof, you could expect to generate about 120 kilowatt-hours (kWh) of electricity per month.

Then, to find out how many kilowatt of panels you need to instal to meet your home’s electrical needs, divide your annual energy bill by 120 kWh. The ratio of your energy usage to your daily average is 893 kWh / 120 kWh = 7.44 kW, so a 7.5 kilowatt system would be sufficient to meet your needs.

Finally, suppose the panels you plan to buy have an output of 400 watts. To calculate the number of panels your setup will need, divide 7,500 by 400. The precise number is 18.75, but let’s round up and claim you’d need 19 of such solar panels to power your home.

This same calculation can be used to calculate the optimal number of solar panels for powering a complete house.

Using Solar Energy to Power Your Entire Home

If you have a solid net metering programme in place, your solar panels will always be able to cover your electricity costs even if they can’t power your entire home.

However, solar electricity is likely not cost-effective for you if net metering is unavailable in your region.

That is, until the cost of installations drops.

Battery storage for solar panels can help you save money by reducing your reliance on the grid for power, but they can add a significant sum to the price of your system.

However, solar panels combined with storage are a fantastic option to power a home if you have the financial resources and a major motivation to minimize your environmental effect.

FAQs About Solar Panels

How Efficient Are Solar Panels in Australia?

The average cell efficiency of a solar panel is between 15 – 22%. The level of efficiency varies between manufacturers. The higher the efficiency of a solar panel, the more solar power it will produce per square metre.

How Practical Are Solar Panels in Australia?

In every Australian state, no matter your electricity consumption, solar panels are worth buying in 2022. While there are many variables that impact the cost, savings and payback of solar panels, the upshot is that in Australia they are a good investment.

Is It Cost-Effective to Use Solar Batteries in Australia?

Solar batteries are definitely worth it in 2022 and beyond. As solar feed-in tariffs continue to drop to negligible levels, solar panels just don’t make sense without a battery. Without a battery, you’re paying for your electricity as soon as the sun disappears.

How Long Will a Solar Battery Power a House?

Home solar battery units last anywhere between 5 and 15 years. If you decide to install a solar battery today, it’s almost certain you’ll need a replacement in the future to match the 20- to 30-year lifespan of your solar power system.

If a Home in Australia Is Solar-Powered, Would It Make It More Valuable?

Solar panels could be the best way to increase your property’s value, as well as reduce your energy bill. For many people, their home is their biggest asset and maintaining it properly is crucial to ensure it holds its value.

Conclusion

It is a common question among homeowners to wonder if solar PV arrays can generate enough power to meet their needs. With enough solar panels, a residence can be completely powered by solar energy. If your community does not offer nett metering or you would prefer not to use the local power grid, you can supplement your solar PV system with energy storage. If cost savings is your major goal in going solar, a solar battery is not necessary. Your solar panels can do away with your monthly electricity bills even if you don’t have a solar battery.

Through a system known as “solar nett metering,” regular households and businesses can use solar energy to power their operations while still staying connected to the power grid. There are many countries that employ nett metering. To the extent that customers generate solar power, they should be rewarded at a rate that is on par with that of conventional grid power. Solar nett metering and solar gross metering are the two main categories of solar energy metres used in Australia. As an alternative term to “nett metering,” the term “feed-in tariff” has gained popularity.

Each Australian state and electricity provider has different policies regarding the availability of feed-in tariffs. You can benefit financially from Net Metering if your solar panels produce more electricity than you consume. In order to offset the annual energy costs of a typical Australian home, between 16 and 20 solar panels are needed. Panel efficiency, annual energy consumption, and power rating all play a role in determining the ideal quantity of panels for a given home. A solar panel system may produce up to 4.8 kW per hour under optimal conditions.

You only need a 7.5 kilowatt system if you reside in a location that receives at least four hours of sunlight per day. Twenty-nine solar panels need to be installed to fully power a home. Simply divide 7,500 by 400 to get the required number of panels for your installation. To round up, let’s say you’d need 19 of these solar panels to supply enough energy for a house when the actual amount is 18.75.
