The Quiet Revolution in Rooftop Installation Safety

There’s a specific point that anyone who has ever worked on a solar panel installation will be familiar with. It’s the rather awkward dance across a sloping rooftop, solar panel in hand, attempting to balance your own footwork while at the same time trying to protect your expensive array of solar panel equipment. It’s the kind of scenario where you wish you could call for an extra pair of hands, or preferably something rather better.

Enter the solar panel lifting bag. It’s not the most glamorous piece of equipment, perhaps, but it has helped change the way solar panel installation professionals go about their daily work.

What Makes These Things Tick

Solar panel lifting bags, at their heart, are rather simple tools. They can be envisaged as a bag with straps, designed to hold a solar panel securely while in transit to the rooftop and then into place. They usually come equipped with some kind of padding to prevent scratching the surface of the solar panel, and they are designed to be used repeatedly in a commercial environment.

The clever bit of the solar panel lifting bag is the way they enable weight to be distributed and secure handholds to be made. Rather than attempting to hold the edges of a solar panel, and thereby risking your balance and being blown off course by any stray gusts of wind, the solar panel lifting bag enables you to lift the panel in the proper manner. This involves your legs and your core muscles, rather than simply your arms and hands.

Why Installers Actually Use Them

The health and safety argument is obvious, so we won’t labour that point. However, there’s more to it than just a box to tick on a risk assessment form. We’re sure that anyone who has ever dropped a panel will know the feeling that follows. It’s not just the cost of the panel itself, but the time added to the installation, the discussion with the end user, and the paperwork that follows.

What may not be so obvious is how these bags can actually improve the working efficiency of installers who work with multiple panels per installation. When working with twenty or thirty panels on a residential roof, the cumulative time savings per panel can be significant. The ability to efficiently transfer panels from the roof to the ground, for example, can make a big difference in how many installations can be completed in a given day.

A couple of installers have noted that there’s also a reduction in muscle fatigue. While solar panels may not be exceptionally heavy objects, typically ranging from 18 to 25 kilograms, the cumulative effect of lifting them in awkward positions can be tiring. The ergonomic advantage of a good lifting bag can be appreciated after a while.

Variations on a Theme

Not all lifting bags are created equal, however, and there are a number of different approaches to the same basic idea. While some manufacturers favour a sleeve that the panel can be inserted into, others favour straps that go over the edges.

The design of the sleeve is quite effective for protection and weight distribution, although slightly slower to load and unload. The strap-based systems, on the other hand, offer faster access but demand more attention to ensure proper attachment of the panel prior to lifting. There are newer designs that attempt to integrate aspects of both, providing a balance between ease of use and protection.

And size is also a factor here. A lifting bag designed for residential panels will not be large enough for the larger panels now commonly found on commercial properties. Savvy installation companies will already have a range of lifting bags on hand to suit all the panels they are likely to encounter.

The Broader Picture

It is perhaps also worth taking a step back to consider what all this says about the solar panel industry as a whole. With increasing numbers of installations now taking place, it is perhaps not surprising to see a degree of maturity creeping into the industry – albeit a maturity which benefits everyone involved.

Twenty years ago, installing a solar panel was a relatively rare occurrence – but one which still needed to be done nonetheless. And as a result, the tools available to do the job have also improved significantly – from a position where installers had to make do with general-purpose building equipment to the specialised tools now available.

This is a process which benefits everyone – from the installer themselves to the end client to insurance companies to the overall quality of the final product.

Final Thoughts

The lifting bag for solar panels is not a product which is likely to win any design prizes – nor is it likely to feature prominently on any marketing material for renewable energy installations. And yet for those who actually use these tools – climbing around on a rooftop on a cold and rainy night, while also trying to meet a deadline – it is a genuine step forward for a process which was not previously well-served.

It is perhaps a reminder that sometimes the greatest innovations are not for a revolutionary new technology – but for a solution to a common problem which someone has finally bothered to get right.
