The Pros and Cons of Integrated Solar Panels

Integrated solar panels are seamlessly embedded into a building’s roof, unlike traditional panels mounted on top. They blend with the roof design, providing a cohesive and aesthetically pleasing solution, especially for older or heritage properties.

Do integrated solar panels perform better than on-roof solar panels?

Integrated solar panels provide special advantages compared to regular on-roof panels. They are a great choice for different roof types, especially older buildings.

Pros of integrated solar panels

Integrated solar panels take the place of roof tiles or slates. This allows the panels to sit lower in the roofline. They look more like a natural part of the roof and less like an added feature.

The aesthetic benefits of roof integration are clear. However, there are other advantages to choosing in-roof panels instead of on-roof ones.

• Integrated panels replace roof tiles or slates, sitting lower in the roofline for a cohesive look.
• Great for roof replacements or re-roofs, integrated panels save time. They prevent the hassle of weathering around fixing hooks, which can cause leaks.
• They eliminate the risk of bird infestations, which can damage and affect system performance.
• Fewer planning restrictions: Integrated solar panels sit flush with your roof, minimizing their visual impact on your home’s design.
• Less maintenance: Solar panels on your roof have fewer gaps and exposed parts. This reduces debris buildup and weather damage.

Cons of integrated solar PV panels

Choosing roof-integrated solar panels has many benefits. However, there are also some factors to think about before deciding.

• Integrated solar panels may convert slightly less sunlight into electricity than traditional panels
• Integrated panels operate at a higher temperature, potentially reducing efficiency slightly compared to on-roof panels. However, the difference is minimal.
• Higher costs for existing roofs: Installing solar panels in the roof can be harder and more expensive than on the roof. This is especially true unless you are re-roofing the property.
• Despite this, the improved aesthetics and seamless design may outweigh these concerns for many.

Integrating solar panels in stone slate

For stone slate roofs, choose your contractor wisely. This complex process often challenges solar companies without roofing expertise. Green and Heritage Roofing has extensive experience in professionally integrating Solar PV systems on stone slate roofs. Especially whilst carrying out heritage roofing or roof replacement.

Do integrated solar PV panels require planning permission

You can install solar PV on most homes without needing permission. The permitted development rules allow this. However, installing solar panels on listed buildings, heritage properties, or those in conservation areas requires special considerations.

What are the best Integrated Solar PV Panels

The best solar panels are debatable, but we find the Clearline Fusion system by Viridian offers quality installations. These sleek panels allow you to reduce energy bills without compromising your home’s beauty, especially on heritage properties.

Cost of integrated solar PV panels

If you’re thinking about installing in-roof solar panels, knowing the solar PV costs is important.

In-roof solar can be pricier than on-roof, unless it’s part of a re-roof or roof replacement. In that case, it’s financially wise to integrate solar panels into the structure.
