Once you’ve decided to go ahead with the installation of solar panels, one of the follow-up questions is typically: how long does the process take?
You might be pleased to know that the answer to this is typically just one to two weeks. However, in Australia (as well as in many other countries), a building permit is necessary to legally install solar panels, and this may take several months before the actual installation can begin. Fortunately, in Australia, not only is the process quite simple, but you may be entitled to a solar rebate as well. One thing to keep in mind, though, is that if you live in a region difficult for labourers to access, your one- to two-week waiting period may extend to a couple of months.
Another thing to note is the complexity of a solar panel system. Not all solar panels are made equal, and systems that have a battery backup will add time and money to your project. Selling all of the excess energy that your solar panels produce might sound like a great idea in theory, but ensuring you have an extra reserve of power might be useful to have at a future date. As for the labour breakdown, it is technically possible to get 20 basic 3-kilowatt solar panels up and running within one to two days, although this shouldn’t be used as a baseline, as planning and assessment are crucial factors. Labour time averages approximately 75 hours, with 49 man-hours for electrical installation and 26 man-hours for non-electrical work.
It goes without saying that more complex architecture, especially buildings with unorthodox contours, can significantly delay the completion date of the design phase. With all this in mind, there is one important thing to remember: the solar panel installation is improving every year, with more advanced panels and installation techniques, and the time it takes to fit solar panels to your home or business will only continue to decrease.
