Exploring the Pros and Cons of Solar Roof Tiles

What Are Solar Roof Tiles?

Solar roof tiles, also referred to as solar slates, solar shingles, or photovoltaic (PV) roof tiles, are designed to mimic the appearance of traditional roofing materials while producing electricity for your home from solar energy.

These tiles and solar panel systems are typically made from materials like glass, ceramics, or polymers embedded with photovoltaic cells.

They come in various styles, colors, and sizes to suit different architectural aesthetics.

Can You Put Them On Slate Roofs?

Yes, but the installation process must be carefully planned to avoid damage to the PV slate.

Due to the delicate nature of the slate, careful consideration must be given to the weight of solar panels and the installation process to prevent damage to the roof structure.

Can You Add Them To A Conservation Area?

Depending on the situation, tiles may be a more subtle way of adding renewable energy to a listed building.

Are They Worth It?

In the ever-evolving quest for sustainable and renewable energy sources, solar power has emerged as a prominent solution. Solar panels, often mounted on rooftops, have become a familiar sight.

However, advancements in technology have paved the way for a more discreet and integrated solution.

These tiles seamlessly blend solar energy generation with traditional roofing aesthetics, providing homeowners with a promising alternative to conventional solar panels.

In this blog post, we'll cover the pros and cons to help you determine if they are a worthy investment for your home.

Solar Roof Tiles pros and cons

What Are The Pros?

Benefits of solar tiles include:

1. Aesthetic Look: One of the most significant advantages is their ability to seamlessly blend with the overall design of your home. Unlike traditional solar panels that sit on top of the roof, solar tiles are integrated directly into the roof structure, maintaining its visual appeal.

2. Enhanced Home Value: Homes equipped with solar energy systems often see an increase in property value. PV tiles, with their unobtrusive design, can contribute to this value appreciation while also attracting eco-conscious buyers.

3. Space Utilization: Solar tiles make the most of available roof space. Since they replace conventional roofing materials, they effectively serve a dual purpose – protecting your home from the elements and generating renewable energy.

4. Save On Your Bills: Solar tiles generate electricity from sunlight, which can significantly reduce your reliance on traditional energy sources. This can lead to lower electricity bills and a smaller carbon footprint.

5. Durability: High-quality solar tiles are built to withstand the elements and offer excellent durability, often comparable to traditional roofing materials. They are designed to resist harsh weather conditions and can last for decades.

Cons of Solar Tiles

1. Higher Initial Cost: They tend to be more expensive to install compared to traditional solar panels. The advanced technology, integration into the roofing structure, and aesthetic considerations contribute to the higher upfront investment. Disadvantages of solar roof tiles include the costs of installation.

2. Complex Installation: Installing solar panel tiles requires specialized skills and expertise, which can translate to higher installation costs. Improper installation can lead to inefficiencies and maintenance issues down the line.

3. Lower Efficiency: Solar tiles might have slightly lower energy efficiency compared to traditional solar panels. This is due to the need to balance aesthetics with functionality, which can result in fewer solar cells per square foot.

4. Maintenance Challenges: If a single tile becomes damaged or malfunctions, it can be more challenging to repair or replace compared to traditional solar panels. This complexity can lead to higher maintenance costs.

5. Limited Style Options: While solar tiles come in various styles, the options might still be limited compared to traditional roofing materials. This limitation could impact your design preferences and choices.

Are Solar Tiles Worth It?

The decision to invest in these ultimately depends on your priorities. If you’re after a more impressive look, and you're willing to make a higher upfront investment, solar tiles can be an excellent choice.

They offer the dual benefit of generating clean energy while maintaining the visual appeal of your home.

However, if cost-effectiveness and maximum energy efficiency are your primary concerns, traditional solar panels might be a more practical option. They generally have a lower upfront cost, higher energy generation efficiency, and are easier to maintain.

In the UK, where the demand for sustainable energy solutions is on the rise offerings from companies like GB Sol and Tesla, have gained traction.

It's important to research thoroughly, consult with experts, and consider your long-term energy goals before making a decision.

In conclusion, solar roof tiles represent a promising leap towards integrating renewable energy sources into the fabric of our homes.

We had a great experience with CRG…

“We had a great experience with CRG installing our solar panels and battery. Pre-install I had quite a few questions and they were always answered quickly and in an easy to understand way. During the installation the team discovered that it wasn’t going to be as straightforward as they initially thought due to the strange layout of our house and the location of the electrical fuse box etc but they did a great job of working out a route for the cabling that caused the least disruption. Since the install I’ve had another couple of questions about configuring the system and again, I got a quick and helpful response.”

Joyce Scott

A pleasure to deal with.

“From the initial survey till completion of the installation I have been most impressed. There was no hard sell, everything was explained clearly. Once I had accepted the lead date was just a matter of weeks. The actual installation was completed very efficiently. The backup support is second to none. l can't recommend Frank, Melissa and the team more highly for the whole experience.”

Paul Wickenden

Very impressed

“Frank came out to measure and quote for solar panels. He was professionally and quick with his quote. We did not feel rushed or pressured into purchasing at all.
Timescales were accurate and their communication was speedy and sincere.
Installation was brilliant. You could tell the installers knew exactly what they were doing.
Warning- The app to see your solar usage and generation is addictive!”
