What Are The Best Solar Panels in Perth?

It’s no great secret that solar panels are a great investment. There are practically no other opportunities that offer such a sound (and government-backed) rate of return with so little risk.

As a homeowner, you’ll still want to maximise your investment as much as possible to get the best return for your money. And there are still many ways through which errors can be made, such as installation accuracy, solar panel quality, or overall system output.

This article is going to walk you through the best solar panels so you don’t go wrong with your purchase. By using only the best solar panels, you can ensure the most appropriate output for your home. Remember that solar panels are 25-year investments – so choose carefully!

Understanding solar panels

First, we need to understand a little bit about solar panels before you can pick the right ones for your house. Solar panels convert the energy captured from sunlight to DC and then to AC, which is also known as usable electricity. Sunlight hits the panels and the DC is converted to AC through the use of an inverter.

The more solar panels you have, the more electricity will be generated. But the overall amount of power depends on the level of sunshine your location gets. This is the number one consideration. Regardless of how many solar panels you have and how efficient they are, they won’t generate anything without available sunlight.

Solar panels are usually made from either polycrystalline or monocrystalline silicon. Though there are other types, it is primarily these two that are used for residential or retail purposes. Monocrystalline solar panels are more efficient but are also more expensive than polycrystalline solar panels.

Finally, you need to understand the Small-Scale Technology Certificate (STC) system. This is the official name of what is commonly known as a government rebate. Certified solar installers offer quotes for the supply and installation of solar panels that are reduced in cost due to STCs. So the advertised price and quote includes the government rebate or STC discount. The bureaucracy has been taken out of the equation for the consumer who just needs to know the end price.

How do I choose a solar panel?

Now that you understand the basics of the solar ecosystem, let’s investigate how you would go about choosing a solar panel. In a step-by-step sequence, you would:

  1. Take stock of how much power your household consumes.
  2. Find a solar panel system that matches your household output.
  3. Take note of the efficiency ratings per solar panel.
  4. Take note of the financial stability of the panel manufacturer.
  5. Look at the product and performance warranties to ensure your solar panels stand the test of time.
  6. Use an online cost calculator to get a realistic estimate of how long it takes for the solar panel system to pay for itself.

When you stick to the high-quality solar panels that we mention later in this article, you can be sure you’re working with reputable manufacturers with excellent customer service and strong warranties. There is no point in messing around with inferior solar panels. The best panels will have efficiency levels between 19-23%, and this is only achieved with monocrystalline solar panels (polycrystalline solar panels being more in the region of 12-18%).

Note that solar panels will come with a Tier rating. You will hear that a solar panel is classed as Tier 1. This has nothing to do with the efficiency of the panel or anything to do with the panel at all for that matter.

It refers to the financial stability of the company producing that panel. These are long-term investments that need to last for decades. So you need to work with a long-standing manufacturer that honours its warranties and provisions.

You could also purchase Tier 2 or Tier 3 panels, though it’s generally not recommended. The difference is that they will not meet the following criteria of Tier 1 producers:

  • 5 years or more of solar panel manufacturing experience
  • Publicly listed on a stock exchange
  • Strong and stable balance sheet
  • Fully automated production
  • A high degree of vertical integration
  • Significant investment in the marketing of their brand.
  • Highly regarded reputation for quality and service within the solar industry

Basically, Tier 1 panels are of a higher quality and are more reliable. As such, they tend to cost between 10 – 30% more. Examples of Tier 1 panel producers include Jinko, Sunpower, Trina, and LG. They also tend to have better manufacturing processes and quality control. As such, the products last longer without defects.

What are the best solar panels?

The following solar panels are among the best in the market. Note the Tier 1 rating and the 25-year performance guarantee. If your solar panel loses efficiency quickly then it will cost you a lot of money over the long term. This is why the efficiency levels, backed by the performance warranty from a reputable company, is of such paramount importance.

You may also note that the upfront cost is not as significant as you would think. If you have to pay an extra $1,000 for a solar panel system from a reputable company, you will easily make the money back over the long term with an increase in quality and efficiency.

How much do solar panels cost in Perth?

Remember that the price of the best solar panels will be all-inclusive of installation. So when you get a quote from an installer, you will get everything provided the installer has taken a look at your roof in person. Sometimes it can be difficult to get these installed if you have a sharply angled roof or a three-storey house.

Perth happens to be particularly cheap as far as solar panels are concerned. The government rebate system can reduce prices by around 30% of the total cost. For a 6.6 kWh solar panel system in Perth, you can expect to pay between $5,000-7,000 including the rebate reduction. A 6.6 kWh system is fairly standard for families in Perth.

Be mindful if you are getting a so-called great deal on solar panels. If it’s too cheap, then you may not be getting the best value for money. It can’t be reiterated often enough: small errors in the beginning can hurt you for the next 25 years with lower efficiency levels. Do the research, and you’ll benefit from a better install and a superior solar power system.

What features will the best solar panels have?

The most important features for a solar panel to have are given below. Make sure to query your installation professional as to the following:

  1. Panel efficiency (ideally 19-23%)
  2. Overall system capacity (to meet typical consumption, usually between 5kwH to 7kWh)
  3. Manufacturer Tier rating (Tier One only)
  4. Product warranty (10 years minimum)
  5. Performance warranty (80% after 25 years minimum)

Once these criteria have been satisfied, you know you have a quality solar panel that will stand the test of time and meet your energy requirements.

Is Perth a good place to install solar panels?

Perth is actually one of the top cities for solar power in all of Australia. As we mentioned above, the number one consideration is how much sunshine a given area gets. And Perth ranks quite highly with an average of 5.8 hours of peak sunshine per day per square metre. When you take into account the high electricity prices you would be paying and the powerful discounts for installation, Perth is the ideal location to install the best solar panels.

Given the levels of sunshine and the generous discounts on offer, you’re losing money every day when you use electricity from the grid. Many providers will offer payment systems so you don’t have to pay for the installation upfront, so there is truly no good reason to avoid a solar installation on your residential or commercial premises.
