Solar Panel Shopping Guide: Key Considerations for Buyers

Are you considering shifting to solar power but don’t know where to start? With so many options available, deciding which solar panels to buy can be overwhelming. However, with a few key considerations, you can make a knowledgeable decision and invest in a system that will provide cost-effective power for years.

1. Efficiency

The capability of a solar panel refers to the sunlight it can convert into electricity. This is an important consideration because higher-performing panels will generate more power and help you save money in the long run. Look for panels with an efficiency of at least 15%, although you can find more efficient panels that can convert up to 22% of sunlight into electricity.

One way to compare efficiency is to examine the panel’s wattage rating. Higher-wattage panels will produce more energy but may also be more expensive upfront.

2. Size

The size and wattage of a solar panel determine how much electricity it can generate. For example, a larger panel with a higher wattage rating will produce more energy than a smaller panel with a lower wattage rating.

However, larger panels may only be suitable for specific locations, especially if you have limited roof space or live in a neighbourhood with strict size restrictions. In such cases, you may need to balance the desired energy output with the space. After all, a smaller panel that fits within your available space may still provide enough energy to meet your needs.

3. Durability and Warranty

Solar panels last for decades, but investing in high-quality panels that can withstand harsh weather and last for years is important. Look for panels with a durable frame made of materials like aluminium or stainless steel and a warranty of at least 25 years. A good warranty will ensure you can get support and maintenance if anything goes wrong with your system.

4. Price and Affordability

Solar panels can be a significant investment but are also a long-term, cost-effective power solution. When shopping for panels, consider the upfront cost and the ongoing savings you’ll enjoy from generating your electricity. 

While more expensive panels may have a higher efficiency rating, there may be more cost-effective options for your needs. In this case, always research and compare prices from different manufacturers and retailers to find the best value for your budget.

5. Brand and Reputation

When investing in solar panels, choosing a reputable brand with a proven quality and reliability track record is important. Avoid buying from unknown or unproven brands, as they may offer a different level of support and warranty than established brands. Look for brands with a strong presence in the Australian market and a history of positive customer reviews.

6. Installation and Maintenance

Hiring an experienced professional to install solar panels is necessary. Before purchasing the panels, search for installers from your area and select one with an excellent reputation and expertise in installing the type of panels you desire. Moreover, consider ongoing maintenance and cleaning requirements for your panels to ensure they function efficiently.
