What are Integrated Solar Panels?

Intergrated Solar Panels Manufacturers

If you’re one of the many homeowners who wants to generate their own electricity with solar technology, but you’ve been putting it off because you don’t want to (or can’t) add panels on top of your roof, roof integrated solar could be your solution.

What are Integrated Solar Panels?

Integrated solar panels are also referred to as in-roof solar panels. They are essentially the same as traditional solar panels which are installed on top of roof tiles or slates, but these panels are integrated into the roof, i.e. they replace a section of your roof with no tiles underneath. Integrated solar panels are designed to be weatherproofed and to be as strong as normal roof tiles but also include the photovoltaic cells to generate electricity for your home.

Although sometimes referred to as solar roof tiles, integrated solar panels are not designed to look like roof tiles or slates and generally aren’t a complete roofing solution. If you’re looking for a complete solar roof replacement take a look at What are Solar Panel Roof Tiles?

Pros of Integrated Solar Panels

Aesthetics

On-roof solar panels have a reputation as being bulky and unsightly and while more recent models are far more streamlined in design, integrated solar panels go one step further. As they’re installed as part of the roof’s structure, they sit flush with the roof tiles and blend in more seamlessly. Arguably a more attractive option than on-roof panels which could be of particular importance if you may want to sell your home in the future.

Lightweight

Installing solar panels on top of tiles will add weight to the structure of the roof which could cause issues over time. With roof integrated systems no mounting frame is needed, a section of standard roof tiles are removed and replaced with lighter PV panels which means no additional weight is added.

Cost

When the concept was first introduced to the market integrated roof panels were significantly more expensive than on-roof panels. However, as the technology has become more popular and more and more manufacturers are offering integrated solutions the costs have come down considerably. In addition, integrated solar is a less costly option than a complete solar roof replacement.

New Builds & Roof Replacements

While roof integrated panels can be retrofitted they are best suited to new build projects or roof replacements. This is because the PV panels are fitted at the same time as the roof tiles, meaning installers won’t need to walk on the finished panels which can cause fine cracks which only become noticeable some time later after weathering. Installing the solar at the same time as the roof means replacements are much less likely to be needed.

Restricted Planning Permission

As integrated solar panels are designed to sit flat with the roof and often in a similar colour scheme they are often more likely to meet planning permission in listed buildings or protected areas. In addition, as they’re not adding to the weight of the roof they may be a better choice for older, more delicate architecture.

Cons of Integrated Solar Panels

It’s worth noting that integrated solar panels are usually around 5-10% less efficient at generating energy than on-roof solar panels. This is because on-roof panels have a gap between the panel and roof tiles which allows air to circulate, keeping the panels at a lower temperature. Integrated panels don’t have this ventilation and so are operating at higher temperature.

While retrofitting integrated solar panels into an existing roof is possible, this is a more complex and potentially costly installation than on-roof panels.

How Much Does Roof Integrated Solar Cost?

The cost of integrated solar is comparable to traditional on-roof solar installation, but it is difficult to estimate as there are so many factors to consider e.g. whether it’s a new build or retrofit, how much energy you need the panels to generate, which manufacturer you choose.

Manufacturers usually don’t publish prices as each installation is so unique. The exception to this is IKEA selling Solarcentury’s Built-In Plus; this 6 panel system is listed on their website as costing £5,250.
