There are so many small things that can go wrong on site that can impact the efficiency and profitability of an install, so it's important to have a well-trained, safety-conscious crew and to ensure errors made on site don’t lead to costly call backs later.
With that in mind, the fourth part of the Enphase Solar Survival Guide took shape, focusing on smart jobsite strategies such as what safety equipment to use, and how to best use it, how to interact with and create realistic expectations for customers, how to avoid costly errors, and how to test your system on site so that you don’t need to make a return trip.
For instance, in most installation situations, crews will not be able to see the roof beams that are needed to connect system mounting attachments to the rooftop. Because of this, installers often use their ears to test for stud locations: tapping with their hammer and listening for what sounds like a solid reverberation. This can lead to costly errors that you don’t necessarily catch at the time, and lessen the chance of creating leaks in the customer’s roof.
To avoid that problem, crew trainers we spoke to recommended drilling pilot holes every few feet to ensure that you will be drilling into the stud. If you’re on the mark, you can proceed without hesitation, but if the lag bolt spins because it isn’t firmly seated into the stud, you can simply remove your equipment from that spot, fill the hole with caulking, and drill a new hole, without any harm done, and avoiding possible unhappy customer situations down the road.
That’s just one situation where some extra foresight can save you time and money. For more examples and straightforward solutions, download part four of our Solar Survival Guide.
