The weight and size of solar panels have been increasing lately and so has the risk of various injuries and worksite incidents.

The Increase in Solar Panels Size and Weight

The demand for larger solar systems is increasing, and so is the weight of the panels.

In the past couple of years, there’s been around a 20% increase in the average size of solar panels, with 401kW panels being the favourites for organisations. The increase in size means there also comes an increase in weight with 400 watts system weighing 22.5 kg and 480 watts weighing 26.5 kg. 

Risks & Issues Associated with Size and Weight 

As the solar panels get heavier, it poses an increased risk of muscular or skeletal injury. Moreover, it can also increase the risk of installers falling off a ladder, particularly in windy conditions. 

Not only the carrier, but the heavyweight and bigger size can cause damage to the roof itself. A roof has its own load-bearing capacity – allowing a certain amount of weight to be carried by the internal structure without collapsing. 

Although the roof can sustain the weight of the solar panels, delivering it with heavy tools such as 750-800 kg Pallet on top of the roof could compromise its capability to support the weight.

Although all the risks above seem daunting, they can be reduced by using the HERM panel lifter.
