Important Considerations When Choosing Solar Panels
When picking solar panels, you need to think about a few key things. These factors can make a big difference in how well your solar system works and how much you save.
Quality of Panels and Inverters
Solar panel quality matters a lot. Good panels last longer and make more power. They cost more at first but save money over time. Cheap panels might break sooner and make less power.
This means you’ll need to fix or replace them faster.
Inverters are just as important as panels. They change the power from your panels into power your home can use. Good inverters work better and last longer. Cheap ones might fail after just five years.
Replacing a cheap inverter can cost about $2,000. It’s smart to pick high-quality panels and inverters from the start.
Installation Complexity and Costs
Solar panel costs can go up if your roof is tricky. Steep slopes, odd shapes, or hard-to-reach spots make the job harder. This can add up to 20% more to your bill. But don’t worry! Most homes have simple roofs that are easy to work with.
Costs also change based on what’s already on your roof. Things like vents, chimneys, or skylights can make the job more complex. The team might need special tools or more time. This can bump up the price a bit.
But a good solar company will check all this before they start. They’ll give you a clear price that covers everything.
Roof Space and Positioning
Roof space and positioning play a big role in solar panel setup. Your roof’s size and shape affect how many panels you can fit. A 4-bedroom house often needs about 32 panels, which take up a lot of space.
The way your roof faces matters too. Panels work best when they point north in Australia. They also need a good angle to catch the most sun.
The layout of your roof can make installation easy or hard. A simple, flat roof is easier to work with than one with lots of angles. Shade from trees or buildings can block sunlight and lower panel output.
It’s smart to check these things before you buy panels. Next, let’s look at how to pick the right solar company for your needs.
How Solar Rebates Impact Overall Costs
Solar rebates can slash the cost of your solar panel system. In Australia, the government offers Small-scale Technology Certificates (STCs). These STCs act as a discount on your solar setup.
The current average STC price is about $39.30. For a 6 kW system, you could get 49 STCs. That’s a rebate of around $1,955! This big saving makes solar more affordable for many Aussie homes.
The impact of rebates varies by state and system size. Bigger systems often get more STCs, leading to larger discounts. Some states also offer extra incentives on top of the federal scheme.
These can include feed-in tariffs or additional rebates. It’s smart to check what’s available in your area. With these rebates, the payback time for your solar investment can shrink significantly.
Choosing the Right Solar Installation Company
Picking a solar installer is a big step. Here’s what to look for in a good company:
- Check their experience. Look for firms with at least 10 years in the field.
- Ask about energy bill savings. Top companies help cut bills by 50% or more.
- Look at their track record. The best installers have happy customers.
