How to Choose the Best Solar Panels in Australia

Aussies are investing in solar power at an increasing rate recently as the prices of the most popular solar panel brands are decreasing. But, which solar power unit should you choose?

Well, if you were bitten by the green bug, consider the following factors.

The Size of the Solar Panel Array

If you are wondering how many solar panels to get, consider several factors: your roof size, the amount of sun exposure you get, and your household’s energy demands.

Typically, for a five-person home, customers get 5kW solar panel packages that combine 20 individual solar panels in a surface area of 32 m².

The bigger solar systems often include a battery. For more details, read our guide on the size of solar panels.

Do You Need Solar Storage Batteries?

This energy-storage device lets you use the electricity you capture via the solar panel array (or from the grid) at a later time. For example, you can generate electric power during the day and use it throughout the night, or you can drain the battery during power outages.

However, this nifty invention comes at a premium price that you might not be able to pay off in a long time. Therefore, carefully consider whether or not you will generate electricity that you will store for future use, or even export to the grid, to justify its purchase.

Generally, storage batteries don’t make total economic sense for most homes. If you’re considering adding a battery, visit our guide to solar storage batteries to understand the pros and cons.

Solar Panel Types & Installation

If you need a highly efficient panel that degrades slowly and can be used in limited spaces, go with a monocrystalline panel. However, choose the cheaper polycrystalline option if you live in a remote area with a changing climate. Buy a quasi-monocrystalline system for the best of both worlds (albeit with unpredictable prices and availability).

Any solar panel comparison should also include the costs to hire accredited installers since end consumers should not set up the product on their own. Those who take that risk will void the product warranty, and they might damage the product or hurt themselves.

Cost & Warranty

Most solar panel ratings include price as the top factor to consider when converting to solar energy. However, while high prices equal high quality most of the time, you should review your exact needs to ensure you do not overpay, thus enjoying a quicker payback period.

The best indicator that you are getting the best performance and durability per dollar is the warranty duration combined with the brand’s reputation. Getting a panel from a reputable brand like WINAICO, covered by a 25-year warranty, is a sure sign that you are buying right.

Ending on a Sunny Note

Installing a solar panel system is undoubtedly a significant investment, and making the wrong choice could end up costing you more in the long run. Hence, carefully go through our best solar panels in Australia review, shop around, and compare different prices to make sure you find the best value for your money.
