With electricity costs remaining an important consideration for Australian households, many NSW homeowners are asking whether installing solar panels is still worthwhile in 2026.

The answer depends on your household, how much electricity you use and how well a solar system matches your energy needs. Solar can help reduce the amount of electricity you purchase from the grid, but the benefits vary from home to home.

Here’s what to consider before investing in solar.

1. How much electricity do you use during the day?

One of the biggest factors affecting the value of solar is how much of the electricity you generate you can use yourself.

Solar panels typically generate the most electricity during daylight hours. If someone is home during the day, or appliances such as washing machines, dishwashers and pool pumps can run while the sun is shining, you may be able to use more of your solar electricity directly.

Using your own solar generation can reduce the amount of electricity you need to buy from your retailer.

If your household is usually empty during the day, you may export more excess electricity to the grid. Solar can still be worthwhile, but your savings will depend on your usage patterns, electricity plan and whether a battery suits your needs.

2. Are solar feed-in tariffs still worth it?

When your solar system generates more electricity than your home needs, the excess can generally be exported to the grid.

Your electricity retailer may pay you a solar feed-in tariff for that exported electricity. However, rates vary between retailers and electricity plans, and they may be considerably lower than the price you pay to buy electricity from the grid.

This means it is not always beneficial to focus on generating as much excess electricity as possible.

Instead, a well-designed system should aim to match your solar generation with your household’s energy use.

When comparing electricity plans, look at the full picture: usage rates, supply charges, feed-in tariffs and any time-of-use pricing that applies.

3. Do you need a solar battery?

A battery is not essential for every household installing solar.

Solar panels can reduce your grid electricity use during the day without a battery. A battery adds the ability to store some excess solar generation for use later, including in the evening.

Whether that additional investment makes sense depends on your energy consumption, electricity tariff, battery cost and how much surplus solar energy is available to store.

If you’re considering a battery, read our guide to Solar Battery Rebates NSW 2026⁠ to understand the incentives that may be available.

It is worth comparing the cost of solar alone with a solar-and-battery package before making a decision.

4. What about government incentives in 2026?

Government incentives may help reduce the upfront cost of eligible solar and battery installations.

For NSW households, options worth investigating include the Australian Government’s Small-scale Renewable Energy Scheme and the NSW Home Energy Saver Program, subject to their respective eligibility requirements.

Battery incentives are separate and have their own rules. Not every household or system will qualify.

We’ve covered these programs in more detail in our guides to the NSW Home Energy Saver Program⁠ and solar battery incentives in NSW⁠.

Always check the latest official guidelines before relying on an incentive when budgeting for your installation.

5. Choosing the right solar system size

A larger solar system is not automatically the best option.

The right size depends on factors such as:

• Your household’s electricity consumption
• When you use the most electricity
• Your roof space, orientation and shading
• Whether you plan to install a battery now or later
• Your budget and future energy needs

For example, a household with high daytime electricity use may benefit from a different system size than a household that uses most of its electricity after sunset.

Reviewing your recent electricity bills can help an installer understand your consumption and recommend a system that better suits your needs.

6. How do you know if solar is worth it for your home?

Before committing to an installation, consider these questions:

• How much electricity does your household use each quarter?
• How much of that electricity is used during daylight hours?
• What are your current electricity rates and supply charges?
• How much excess solar electricity are you likely to export?
• Would a battery provide enough additional value to justify its cost?
• What is the total installed price after any eligible incentives?
• What are the estimated savings, and what assumptions are those estimates based on?

Ask for a clear explanation of the system’s estimated performance and financial assumptions. Savings and payback periods are estimates, not guarantees, because electricity prices, household consumption and system performance can change.

The bottom line: Is solar still worth it in 2026?

For many NSW households, solar remains worth investigating in 2026. The key is choosing a system that matches your electricity use rather than simply installing the largest system available.

Understanding your energy habits, comparing electricity plans and obtaining a properly designed quote can help you make a more informed decision.

Frequently asked questions

Is solar still worth installing in NSW in 2026?

It can be. The potential benefit depends on your electricity consumption, solar generation, electricity plan, installation cost and how much of your solar electricity you use directly.

Is solar worth it without a battery?

Yes, solar panels can reduce grid electricity purchases without a battery. A battery is an additional investment that may help you use more of your solar generation after sunset.

Are solar panels less worthwhile because feed-in tariffs are lower?

Lower feed-in tariffs can reduce the value of exporting excess electricity. Using more of your solar generation at home can therefore be an important part of maximising its value.

Should I install a battery at the same time as solar?

Not necessarily. Compare the upfront cost and expected benefits of both options. Your budget, energy use and future plans will help determine whether installing a battery now makes sense.
