People have often asked what should be done about bird’s nests under solar panels. Normally speaking it gets too hot under the panels, so that the nest is often empty. However, birds may continue to actively build nests, even after you remove the twigs. Are you irritated by the sounds on the roof or would you like to protect your solar panels, so that it’s difficult for birds to build a nest? Then we have a solution for you.


Why must solar panels be protected against birds? The output from the panels decreases when the natural ventilation beneath the panels is restricted by twigs and nest material. The hotter the panels get, the lower the efficiency. There is even an increased risk of fire. No more noise nuisance from birds between the roof and the solar panels. The twigs the birds bring may also cause scratches on the back sheet of the panel, which may result in earth leakage problems. Birds should not really have the chance to nest there.


If your solar panel consists of an aluminium profile on the inside, the BirdBlocker can be mounted quickly and easily with our customised clipping brackets (included). The BirdBlocker bird protection offers a 99% certainty that the birds under the solar panels will stay away. However, the birds may still find a way through the strips. You can also assemble the BirdBlocker yourself or have this done by a handyman. We only assemble these strips when we install the solar panel systems ourselves. This is in connection with the guarantee on the system. The BirdBlocker is supplied per linear metre. It includes 7 stainless steel clips for securing the BirdBlocker. Please note: the Birdblocker must not be screwed or glued in place. The guarantee on your panels may be at stake if you screw or glue the Birdblocker.

Applying BirdBlocker gives many benefits for the solar panel owners.

    • optimal ventilation is retained for the best efficiency
    • reduces risk of fire
    • minimizes noise nuisance from the birds
    • uv-resistant
    • 100% recyclable
    • minimizes chance of damage to backsheet solar panel by nest material
    • no clogged gutters due to residual waste on the roof
    • beautiful appearance of the roof due to fewer excrements from the birds
    • robust and durable
    • no screwing or drilling needed, so guarantee on the panels will be kept
    • 10 year product warranty on the material


This is a system that aims to keep birds away from under solar panel systems on sloping roofs, with the result that the birds cannot build nests there. The BB100 consists of a plastic strip with narrow fingers that are 10 cm high and has a width of 100 cm. If the inner of your panels has a flat aluminum flange, the BirdBlocker can be mounted quickly and easily using the supplied mounting material, which has been specially developed for this purpose. The BB100 also fits on the Valk Pro+ flat roof system.


This version will bridge max. 115mm between the panel and the roofing. A big advantage is that, just like the BB200, there will be a bridging between the needles halfway. Corners and the space under the profiles are closed. Additional UV-blocker has also been added for even longer life. The BB125 is the most commonly used type.

This system fights birds under solar panel systems on sloping roofs with a larger ventilation gap between roof and panel up to 195mm. The BB200 consists of UV-resistant black plastic strip with narrow fingers of 20 cm high and is 50 cm wide. The narrow fingers are interconnected with 2 springs to give extra strength. The fingers can be shortened as desired to fit nicely on every system. The connectable strips can be fixed to the frame of the solar panel using the specially developed stainless steel mounting material. Suitable for almost all solar panels during installation and can be used as a retrofit.



Jackdaws are almost always the culprit. Lots of twigs under the panels may even cause scratches on the plastic foil at the bottom of the panels. If these scratches are deep and even penetrate the plastic, it may lead to a resistance error on the inverter. The system then becomes idle, which is obviously not the intention. This means that the panels in question are damaged beyond repair. With a SolarEdge inverter system, this problem can be detected remotely. When you choose Solarwatt double glass panels, the twigs beneath the panels cannot do any harm, because the lower outer layer of this type of panel is made of glass.

Always follow the assembly instructions when using the system.
