The AIM System
Our Adjustable Inclination Mounting systems (patent pending) for solar panels is a sun awning and solar power system in one. During the summer it provides optimal shading and electricity, while during the winter it folds upwards toward the wall, allowing natural sunlight inside while maximizing energy production thanks to its almost vertical inclination.
The system combines a lower, folding arm and an upper arm which pivots upwards to adjust the angle of inclination between seasons. On these assemblies the solar panel mounting rails can be fixed. The optimum mounting rail depends on the number and type of solar panels, distance between the arms, and local (wind) conditions.
Summer position
In the summer position the panels have an inclination of 35°, which is optimal for latitudes between 45 and 55°. Thus they are aimed directly perpendicular to the sun around noon, ensuring optimal shading and power generation.
In this position, the pivoting arm is rotated downwards, resting in the mounting bracket and supporting the angled arm for additional rigidity of the structure. The folding arm is fully extended and horizontal.
The summer position is the preferred position between the spring and autumn equinox.
Winter position
In the winter position the panels have an inclination of about 5 degrees. As the sun is low in the sky during wintertime, the almost vertical inclination of the panels captures maximum sunlight. In this position they also leave the window almost completely free to allow in as much natural light as possible for passive heating.
In this position the upper arm is pivoted all the way upwards. The angled arm is cradled in this position limiting its movement and absorbing any lateral forces, making the whole assembly extremely sturdy and able to withstand strong wind gusts.
The winter position is recommended between the autumn and spring equinox.
Adjustment
Because the inclination of the system is only intended to be changed once every six months, the standard is to do this manually, just as it is done with regular sun awnings. In the summer position the system is kept in place by gravity assisted by torsion springs. By tightening the dyneema rope with the winder mechanism the system is pulled towards the building and lifted into the winter position. Moving the system into the winter position also cradles the arms so the assembly is even sturdier.
Materials
The construction is made of extruded aluminium, which is strong, lights, and extremely corrosion resistant. All nuts and bolts are stainless steel, while the winding mechanism is cast aluminium. The cord is dyneema, a high-end, extremely strong polymer fibre. All materials used have been selected for their ability to withstand the elements for may years.
Installation
Just like a regular sunshade, the AIM solar system has a mounting bracket to directly mount it to the wall. Because the system is subject to the elements year-round, the connection to the wall must be able to withstand more force than a regular sunshade.
The electrical installation is just like with a regular solar system, but some additional care must be taken with the cable routing.
Installation is best done by trained professionals. We’d be happy to help you locate one near you.
Maintenance
The system is designed to last for many years without the need for regular maintenance. For the installed solar panels the manufacturer’s recommendations should be followed. For the AIM mounting system, we recommend an annual visual inspection of the joints and cable. If excessive wear is apparent the affected part should be replaced.
