Perth Solar Panel: How to Pick the Best One

 


Selecting the appropriate solar panel system in Perth can be a daunting task, especially given the variety of products and installers available. With the abundant sunshine in Perth, solar energy presents an efficient and environmentally friendly way to power your home while cutting down on energy costs. Here’s a detailed guide to assist you in finding the best solar panel for your requirements.

Tips to Choose Perth Solar Panels

Check out the following tips to choose the best solar panels in Perth, WA.

1. Assess Your Energy Needs

Begin by evaluating your household’s energy usage to make the most of solar in Perth. Understanding your average monthly power consumption will help determine the size of the system you require. A small family might find a 3-5 kW system sufficient, while larger households could benefit from a 6-10 kW system. Reviewing your past electricity bills can provide valuable insights into your typical usage and peak demands, allowing you to choose the right solar setup for your home.

2. Explore the Types of Solar Panels

There are three primary types of solar panels to consider:

  • Monocrystalline Panels: Renowned for their high efficiency and durability, monocrystalline panels are perfect for homes with limited roof space, as they produce more power per square meter. They perform well in low-light conditions and have a longer lifespan, though they tend to be pricier.

  • Polycrystalline Panels: These panels are generally more budget-friendly but are slightly less efficient than monocrystalline options. They are a good choice for those with a tighter budget and sufficient roof space for installation.

  • Thin-Film Panels: Lightweight and flexible, thin-film panels usually have lower efficiency levels. They are often better suited for commercial applications rather than residential use.

Your choice of panel type will depend on your budget, available roof space, and personal aesthetic preferences.

3. Check the Efficiency Rating  

When selecting solar panels, efficiency is a key consideration. Higher efficiency panels can convert more sunlight into electricity, enabling you to generate more energy with fewer panels. Most solar panels have efficiency ratings that fall between 15-22%. If you have limited roof space or significant energy needs, choosing a panel with higher efficiency will be advantageous.  

4. Evaluate Durability and Warranty  

Given Perth’s harsh climate, characterized by intense sunlight and occasional storms, durability is crucial. Seek out panels that feature sturdy, weather-resistant frames and tempered glass. Solar panel warranties typically cover two main areas:  

  • Product Warranty: This covers physical defects in the panel and usually lasts between 10-25 years.  

  • Performance Warranty: This guarantees a specific level of energy output over time, often ensuring 80-90% efficiency after 25 years.  

Opt for a panel that offers both a strong product and performance warranty, as this reflects reliability and quality.  

5. Choose a Reputable Brand  

The solar market is filled with a variety of brands, ranging from premium to budget-friendly options. While it might be tempting to go for a less expensive panel, well-established brands like SunPower, LG, and Jinko Solar are recognized for their quality and durability. Trustworthy brands provide solid warranties and customer support, which can be incredibly valuable in the long run.

6. Research Inverter Quality  

A solar inverter plays a crucial role by converting the DC electricity produced by solar panels into usable AC electricity for your home. Choosing a high-quality inverter is vital for the efficiency and reliability of your solar system. There are three primary types of inverters:  

  • String Inverters: These are cost-effective and work best in installations with minimal shading. However, they can be less efficient if parts of your roof are shaded during the day.  

  • Microinverters: Ideal for shaded roofs, microinverters allow each panel to have its own inverter, maximizing efficiency even when some panels are not receiving direct sunlight.  

  • Hybrid Inverters: Perfect for those considering battery storage in the future, hybrid inverters are compatible with solar batteries.  

The right inverter type for you will depend on your roof conditions, budget, and any future expansion plans.  

7. Determine the Best Installation Company  

Choosing a reputable solar installer is just as crucial as selecting the right solar panels. Here are some key factors to consider:  

  • Certification and Accreditation: Make sure your installer is accredited by the Clean Energy Council (CEC), which ensures they adhere to Australia’s safety and quality standards.  

  • Customer Reviews: Look for online reviews and request customer references to assess the company’s reliability and after-sales support.  

  • Warranty and Support: Choose companies that provide a comprehensive installation warranty, usually lasting between 5 to 10 years, covering any issues related to the installation process.  

Quality installation is essential, as even the best solar panels will not perform at their best if they are not installed properly.

8. Assess the Return on Investment (ROI)  

While solar panels come with a significant initial cost, they can lead to considerable savings over time. To evaluate the ROI, consider the following:  

  • Government Rebates and Incentives: The Australian government has implemented the Small-scale Renewable Energy Scheme (SRES), which offers financial incentives for solar installations, helping to reduce your upfront expenses.  

  • Feed-in Tariffs: Numerous energy providers in Perth provide feed-in tariffs, enabling you to earn credits or payments for any excess electricity you return to the grid.  

  • Payback Period: Determine how long it will take to recover your initial investment through energy savings. For most systems, the payback period typically ranges from 3 to 6 years, depending on factors like system size, energy consumption, and available incentives.  

9. Think About Future Needs  

Reflect on any upcoming plans that might influence your energy consumption, such as purchasing an electric vehicle or expanding your home. If this is the case, you might consider investing in a slightly larger system or a hybrid inverter to facilitate easy integration of battery storage later on.  

Conclusion: Making the Right Choice  

Selecting the appropriate solar panel system in Perth requires a clear understanding of your energy requirements, budget, and roof conditions. By assessing panel efficiency, durability, brand reputation, inverter quality, and the experience of the installer, you can identify the best option for your home. Investing in solar energy is a wise decision for lowering energy costs and promoting a cleaner environment. With the right support, your solar journey in Perth can be seamless and highly beneficial.
