Everything you need to know about Solar Roof Tiles

Australia is well and truly the sunburnt country, particularly here in Brisbane, with abundant clear skies perfect for solar. In fact, Queenslanders are leading the way in adopting solar technology, with 40% of homes in QLD and SA alone having solar.  It&#;s this combination of plentiful sun and rising energy prices, that create a huge opportunity for Australians to continue embracing solar. If you&#;re looking to make the move to solar, you&#;ll know roof panels are long established and well known, but what about the newest technology - Solar Roof Tiles? If you&#;re looking for a non-obtrusive way to bring solar energy into your home then solar roof tiles could be for you. This blog will explore everything you need to know about this emerging technology. &#;

Solar roof tiles explained

&#;What are solar roof tiles? 

Put simply, they&#;re like traditional roof tiles, but capable of collecting solar energy. Dig a little deeper however, and you&#;ll see how clever they are. What makes them so smart is the fact that they don't require mounting on top of a roof, they actually integrate within a tiled roof giving them the technical classification of Building Integrated Photovoltaics (BIPV). Functionally, this means you can cover more of your roof with solar panels, and aesthetically they fit in seamlessly with your home. 

Now, contrary to what you might be thinking, solar roof tiles don&#;t need to take over your entire roof. The ingenious thing about the product is that by their nature they can slot in seamlessly to a tiled roof. As much or as little as needed. So, depending on your location, budget and energy goals you can create the perfect solar setup for your home.

How they work

&#;How Solar Roof Tiles Work

Just like traditional solar panels, solar roof tiles capture sunlight and convert it into electricity. As with any solar installation, there are other components required. A solar setup of any size needs these three components:

  • Solar Roof Tiles - to capture sunlight and convert it into electricity.
  • Solar Inverter - to convert the captured solar energy into usable electricity which can flow through your home. The Inverter you choose can have arguably the most significant impact on how well your system performs so choose wisely.  
  • &#;Battery storage - does exactly what it says on the tin. A battery will store excess electricity for use later on.

&#;

When it comes to sunlight capture, not all roofs are made equal. Like any purchase, you will get what you pay for. Broadly speaking there are three types of solar panel technology to look out for  - monocrystalline (efficient and expensive), polycrystalline (still efficient but less expensive) and thin film (inexpensive solution).

Most solar roof tile manufacturers use monocrystalline technology which is the most efficient of the three, but also the most expensive. Interestingly, Tesla recently launched a new solar roof tile which actually has the capability, via a thin coloured film on each tile, to blend in with the other tiles on a roof. If you&#;re willing to pay for the privilege of course. But, more on the cost of tiles later. 

&#;Water and weather resistance 

Unlike solar roof panels that are installed on top of a roof, solar roof tiles integrate within a roof. But there&#;s a catch - almost every manufacturer requires you to install their own traditional tiles alongside the solar tiles. This is to ensure a snug and safe and watertight installation. Solar roof tile manufacturers will have their own specific set of installation requirements, so look at them closely when choosing. If installed correctly, water ingress should not be an issue.  

On a side note, should you find yourself on the roof of your home, you can walk on the solar roof tiles. All solar roof tiles are rated for high weather performance and can withstand weight better than other roofing materials like Colourbond or traditional tiles.

&#;

Maintaining a solar roof for top performance &#;

Cleaning and maintenance of your solar roof tiles 

As with any solar technology, you&#;ll need to look after your investment to ensure it keeps producing electricity for your home. To maintain efficiency of your solar roof tiles, they should be kept clear of debris (fallen branches, dust etc) and kept moderately clean. The good news is, unless you&#;re in a dry, dusty environment, rain will usually be just fine to keep your tiles performing well. If you do need to clean them, we do not advise climbing on the roof - simply hose your roof down from the ground. 

The second element is maintenance. As with most technology, solar systems benefit from servicing to make sure everything is performing well, so consider having your provider service your solar roof installation once every 5 years.

What to consider when choosing solar roof tiles. &#;

There&#;s a lot to think about when deciding whether solar roof tiles are right for your home. Now, knowing the basics of what they are and how they work, you&#;re equipped to make a more informed decision. If you&#;re looking to explore further, these are the critical factors to consider to avoid common mistakes when looking at Solar Roof tiles. 

  • &#;Cost - it goes without saying the biggest factor is clearly the cost of installation. Solar tiles can cost more than double the price of traditional solar panels, which ultimately means they will take longer to deliver a return on investment. 
  • &#;Aesthetics - traditional solar panels and solar roof tiles perform the same function, with very similar technology. The biggest difference is how they are integrated with your roof. Consider solar roof tiles if the visual appeal of your home is an important factor. 
  • &#;Installation - solar roof tiles do take longer to install than panels, so set aside plenty of time for the installation. The other thing to consider is that in some instances a roof may not align to the sun correctly, or the roof may be the wrong shape size for traditional solar panels. Roof tiles can be a solution in such cases. 
    Durability
    - where solar panels are installed on top of a roof, solar tiles are integrated within the roof. This means the product is more durable in extreme weather conditions such as high wind, and shouldn&#;t experience water ingress issues. Consider your environment and weather conditions when deciding if solar roof tiles are the right option.
  • &#;Comparative output - solar tiles due to their size and design don&#;t capture as much energy as a solar panel (think one single panel with no wasted space, versus several small tiles interlocking and overlapping). Solar panels can generate up to 30% more energy per square metre versus tiles. So, consider the balance between aesthetics, performance carefully - especially when looking at performance degradation over time. 

Conclusions

Solar tiles are an exciting emerging technology, with the potential to transform the market. However, there are plenty of trade-offs to consider when comparing solar roof tiles against solar panels. While many benefits and performance measures are the same or similar, the critical difference to consider is cost and when you&#;ll see a return on your investment. With roof tiles costing as much as 4x the amount of traditional solar panels, you&#;ll need to decide if the aesthetic benefits outweigh the potentially prohibitive costs.

Read on about this clean energy created from your roof, and learn answers to common questions about solar shingles. 

Common Questions about Solar Shingles 

1. What type of maintenance do they require? 

Timberline Solar shingles are designed to require little to no maintenance. Rain helps wash off any dirt or debris accumulation, but if they need additional cleaning, you can gently rinse them with a garden hose when they are cool. 

2. How durable are they?

Solar shingles offer durable protection from the elements just like a conventional roof does. When you choose solar shingles, your home will be safeguarded from storms and extreme temperatures. They protect your house from costly leaks and moisture infiltration. 

3. Are they warrantied?

Timberline Solar shingles are warrantied against weather conditions such as snow, rain, and wind. 

4. Can the clean energy they produce be measured?

Homeowners who invest in solar shingles can monitor output and track their clean energy production by logging into the GAF Energy homeowner portal. Solar roof monitoring delivers data into your hands and makes it simple to spot any issues. 

5. Are there tax advantages when you have solar shingles installed? 

As a homeowner, you should consult your tax advisor on the solar tax incentives available. Typically, when you install GAF Timberline Solar with Christian Brothers Roofing, you will receive a 26% federal tax credit on solar components, a 25-year SolarMax® Technology Warranty for power output, and a 25-year Golden Pledge® Limited Warranty for performance, workmanship, and waterproofing.

6. Will my solar roof come with batteries or grid connection?

Timberline Solar operates in connection with the electric grid and is well-matched with various energy storage offerings on the market. AC-coupled batteries can be added to existing solar installations at any time. Other energy storage systems may require unique equipment for existing solar installations. 

7. Are solar shingles available in the Kansas City Metro area?

Yes! Innovative, efficient solar shingles are available for your Kansas City home. Contact us at Christian Brothers Roofing to learn more. 

8. How long does solar shingle installation take?

It takes about the same time to install solar shingles as it would take to install a composition shingle roofing system &#; on average, three to five days. During your installation, the roofing contractor will keep you updated on the progress of your solar roof. 

9. Do I need to replace my entire roof to install solar shingles?

Yes. If you want GAF Timberline Solar, you&#;ll need to replace your whole roofing system. Unlike solar panels, which are installed on top of your system, solar shingles are flush with your roof so they must be installed with coordinating shingles engineered for the solar roofing system by GAF.  

10. Why should I choose solar shingles over solar panels?

Timberline Solar incorporates the world&#;s first nailable solar shingle, which roofing professionals can install as easily as regular roofing shingles with a nail gun. This roof-integrated solar system is seamless, waterproof, and mimics traditional shingle installation. 

In contrast, roof-mounted solar panels require specialized installation skills and can puncture your existing roof, creating leaks. When the waterproofing of your roof becomes vulnerable due to the installation of solar panels, your roof will degrade faster, and you&#;ll have costly problems to overcome due to water infiltration. 

Solar shingles are also more pleasing to the eye than solar panels, adding value to your home with better curb appeal than panels. 

11. How much do solar shingles cost?

The price of a GAF Timberline Solar roof varies based on the size and slope of your roof, how much sunlight reaches your roof each day, and more. This roofing system is designed to be affordable and compares to the price of a new roof plus traditional solar panels. 

It pays to create your own energy and save on monthly utilities year after year. The savings you&#;ll experience on utility bills will offset the cost of your new roof over time. With solar roofing becoming more popular, solar shingles can benefit your home&#;s resale value. 

12. How much sunlight do the solar shingles need to produce energy?

Solar power is produced by capturing sunlight and converting it into energy. If trees block solar shingles, they won&#;t produce as they should. Maximum energy generation is accomplished when your roof is free from shade. They are not advised if a roof is heavily shaded due to an obstruction like another building.  

If your roof only has light shading, trees may be cut back to make way for the sun to shine on your solar roofing shingles. But the value of installing solar roofing, even with some shade, can vary from house to house&#;so if you&#;re curious about how solar shingles may work on your home, reach out to a reputable contractor (like us!) and have it evaluated. 

13. Will I save money by going solar? 

Yes. You&#;ll use less energy from the grid and enjoy lower electric bills as a result.
