What Are On-Roof And In-Roof Solar Panels?

Before understanding the benefits and drawbacks, it’s essential to have a brief idea about on-roof and in-roof solar panels.

• On-roof solar panels: These are installed on top of your roof, also known as surface-mounted solar panels. They are the traditional, most common installation method, mounted on racks or frames that sit above the roof’s surface.
• In-roof solar panels: Roof-integrated solar panels are installed directly into the roof, replacing traditional roofing materials such as tiles. These panels seamlessly integrate with the roof structure, making them less visible from the ground.

On-Roof Vs. In-Roof Solar Panels – The Differences

The primary difference between on-roof and in-roof solar is the installation method and how the panels interact with your roof.

• Aesthetic appeal: One of the key benefits of in-roof solar panels is their sleek, integrated design. Because they sit flush with the roof, they look more modern and visually appealing than the bulkier, more noticeable on-roof solar panels.
• Installation process: In-roof solar panels require a more complex installation process because they replace existing roofing materials. This can be more time-consuming and may require additional labour. On the other hand, on-roof solar installation is quicker and less invasive, as it involves attaching the panels to the existing roof structure.
• Roof durability: Since in-roof solar panels are integrated into the roof, they protect the underlying structure. On-roof panels don’t offer this benefit, as they sit on the roof.

Pros And Cons Of In-Roof And On-Roof Solar Panels

Now that we understand the basic differences, let’s look at the pros and cons of in-roof vs. on-roof solar panels to help you weigh the options.

1. On-Roof Solar Panels

Pros:

1. Lower initial costs: Solar installation cost for on-roof solar panels is generally lower because the installation process is more straightforward and doesn’t involve replacing the roof.
2. Quicker installation: Installation is faster than in-roof solar panels, meaning less disruption to your home.
3. Easier maintenance: With on-roof solar panels, access to cleaning and repairs is more straightforward, as the panels are not integrated into the roofing system.

Cons:

1. Potential roof damage: Over time, the racks used for mounting on-roof solar panels could cause wear and tear on your roof, leading to leaks if not installed correctly.
2. More space required: On-roof solar systems need additional space above the roof, which may not be ideal for homes with smaller roofs or those with limited space for solar panel mounting options.

2. In-Roof Solar Panels

Pros:

1. Sleek, modern look: One of the many benefits of in-roof solar panels is that they offer a more integrated, aesthetically pleasing solution as they blend in with your roof design, enhancing your home’s overall appearance.
2. More durable: Since the roof-integrated solar panels replace your roof tiles, they provide additional protection to your home’s structure.
3. Space saving: Unlike on-roof panels, in-roof solar panels do not require extra space above the roof, which is ideal for homes with limited roof area.

Cons:

1. Higher initial costs: The installation cost for in-roof solar panels is generally higher due to the more complex installation process, which requires roof replacement and custom solutions.
2. Longer installation time: Replacing existing roofing materials involves installing in-roof solar panels, which can take longer than on-roof solar panels.

Cost Comparison – On-Roof Vs. In-Roof Solar Panels

The cost is one of the most significant factors when choosing between on-roof solar panels and in-roof solar panels.

• On-roof solar: The solar installation cost for surface-mounted solar panels tends to be lower. These systems typically require fewer materials and less labour for installation. The average cost of installation varies between £5,000 – £6,000.
• In-roof solar: Roof-integrated solar panels require more intricate labour and additional materials, as they replace roofing materials, resulting in higher costs. The average cost of installation ranges somewhere between £6,000 – £8,500.

Which Solar Panel Installation Is Best For Your Home?

Choosing between on-roof solar and in-roof solar largely depends on your personal preferences, budget, and the specific requirements of your home.

1. If aesthetics is important to you, and you’re looking for a clean, modern look, in-roof solar panels may be the better choice.
2. If you have a tight budget or need a quicker solution, on-roof solar panels are likely the better option. The installation is more affordable and faster, making them ideal for those looking to reduce energy savings quickly.
3. Consider your roof’s condition. If your roof is nearing the end of its lifespan, opt for in-roof solar panels, as they will provide a more permanent, durable solution that protects your roof at the same time.
4. For larger homes with expansive roofs, on-roof solar panels offer more installation and panel placement flexibility. In-roof panels, while space-efficient, may be better suited to smaller homes or those with limited roof space.
