Choosing the Right Solar Shingles: A Buyer's Guide
Solar shingles are an increasingly popular alternative to traditional solar panels, offering a sleek and integrated look for your roof while generating clean energy. But with various options available, choosing the right solar shingles for your home can feel overwhelming. This buyer's guide provides practical advice to help you make an informed decision, considering factors like your energy needs, roof type, and climate.
Common Mistakes to Avoid
Before diving in, let's highlight some common mistakes people make when choosing solar shingles:
Ignoring Energy Needs: Failing to accurately assess your energy consumption can lead to undersized or oversized systems.
Neglecting Roof Compatibility: Not all solar shingles are suitable for every roof type or angle.
Overlooking Warranty Details: A weak warranty can leave you vulnerable to costly repairs.
Choosing the Cheapest Option: Prioritising price over quality can result in poor performance and a shorter lifespan.
- Skipping Installer Research: A poorly installed system won't perform optimally and may void warranties.
1. Assessing Your Energy Needs
The first step in choosing the right solar shingles is to understand your energy consumption. This will help you determine the size of the solar shingle system you need to meet your electricity demands.
Calculate Your Energy Usage
Review your electricity bills from the past 12 months to determine your average monthly and annual energy consumption. Look for the kilowatt-hour (kWh) figure. This will give you a clear picture of how much energy you use.
Consider Future Needs
Think about any potential changes in your energy consumption. Are you planning to add an electric vehicle, install a pool, or expand your home? Account for these future needs when estimating your energy requirements.
Factor in Location and Climate
Australia's climate varies significantly from region to region. The amount of sunlight your roof receives will impact the energy production of your solar shingles. Consult with a solar professional to assess the solar irradiance in your area. They can help you estimate how much energy a solar shingle system will generate based on your location's specific conditions.
Use Online Calculators
Many online solar calculators can help you estimate the size of the solar system you need based on your energy consumption, location, and roof characteristics. These calculators provide a helpful starting point, but it's always best to consult with a professional for a more accurate assessment.
2. Understanding Shingle Specifications
Once you know your energy needs, you can start evaluating different solar shingle options. Pay close attention to the following specifications:
Power Output
This refers to the amount of electricity each shingle can generate under standard test conditions. Shingles with higher power output will generate more electricity, potentially requiring fewer shingles to meet your energy needs. Power output is typically measured in watts (W).
Efficiency
Efficiency measures how well a solar shingle converts sunlight into electricity. Higher efficiency means more electricity is generated from the same amount of sunlight. Look for shingles with higher efficiency ratings to maximise energy production, especially if you have limited roof space.
Materials and Durability
Solar shingles are typically made from silicon-based photovoltaic (PV) cells. The quality of the materials and the construction of the shingle will impact its durability and lifespan. Look for shingles that are weather-resistant and designed to withstand harsh Australian conditions, including high temperatures, strong winds, and UV radiation. Consider what Solarshingles offers in terms of durable and weather-resistant options.
Aesthetics
One of the main advantages of solar shingles is their aesthetic appeal. They blend seamlessly with your roof, unlike traditional solar panels. Consider the colour, texture, and overall design of the shingles to ensure they complement your home's architecture. Some shingles mimic the look of traditional asphalt shingles, while others have a more modern, sleek appearance.
3. Considering Roof Type and Angle
Your roof's characteristics play a crucial role in determining the suitability of solar shingles.
Roof Type Compatibility
Not all solar shingles are compatible with every roof type. Some are designed for asphalt shingles, while others are better suited for tile or metal roofs. Ensure the shingles you choose are compatible with your roof's material and structure. Consult with a roofing professional or solar installer to confirm compatibility.
Roof Angle and Orientation
The angle and orientation of your roof will affect the amount of sunlight your solar shingles receive. In Australia, north-facing roofs generally receive the most sunlight. A roof angle between 20 and 45 degrees is typically ideal. However, even east- or west-facing roofs can be suitable, especially with high-efficiency shingles. A solar assessment will determine the optimal placement and configuration of your solar shingles.
Roof Condition
Before installing solar shingles, ensure your roof is in good condition. Repair any leaks or damage before proceeding. Solar shingles are designed to last for many years, so it's essential to have a solid foundation. If your roof is nearing the end of its lifespan, consider replacing it before installing solar shingles. This will save you the hassle and expense of removing and reinstalling the shingles later.
4. Checking Warranty and Performance Guarantees
A comprehensive warranty and performance guarantee are essential for protecting your investment in solar shingles.
Warranty Coverage
Look for a warranty that covers both the product and its performance. A product warranty covers defects in materials and workmanship, while a performance guarantee ensures the shingles will generate a certain amount of electricity over time. Pay attention to the length of the warranty and the specific terms and conditions. A typical warranty period is 25 years for performance and 10-15 years for product defects.
Performance Degradation
Solar shingles, like all solar panels, experience a gradual decline in performance over time. This is known as performance degradation. Check the warranty to see how much degradation is covered and what recourse you have if the shingles don't meet the guaranteed performance levels. A reputable manufacturer will guarantee a certain percentage of the original power output after a specified period.
Claim Process
Understand the process for filing a warranty claim. What documentation is required? Who do you contact? A clear and straightforward claim process is a sign of a reputable company. Learn more about Solarshingles and our commitment to customer satisfaction and warranty support.
5. Finding a Reputable Installer
Proper installation is crucial for the performance and longevity of your solar shingle system.
Licensing and Certification
Ensure the installer is licensed and certified to install solar systems in your state or territory. Look for installers with accreditation from industry organisations. This demonstrates their expertise and commitment to quality.
Experience and Expertise
Choose an installer with experience installing solar shingles. Ask for references and review their past projects. A reputable installer will be able to answer your questions thoroughly and provide a detailed installation plan.
Quotes and Comparisons
Obtain quotes from multiple installers and compare their prices, services, and warranties. Don't just focus on the lowest price. Consider the overall value and the installer's reputation. Ask for a breakdown of the costs, including materials, labour, and permits.
Customer Reviews and Testimonials
Check online reviews and testimonials to gauge the installer's reputation and customer satisfaction. Look for feedback on their workmanship, communication, and customer service. A reputable installer will have positive reviews and a track record of satisfied customers.
Maintenance and Support
Ask the installer about their maintenance and support services. Will they provide ongoing monitoring and maintenance to ensure your system is performing optimally? Do they offer a service agreement? Choose an installer who is committed to providing long-term support.
By following these tips, you can confidently choose the right solar shingles for your home and enjoy the benefits of clean, renewable energy for years to come.
