Commercial solar was a bit slower to take off than residential solar, but businesses are really just starting to recognise now the value of putting solar in, and it's a great return on investment. You're looking at anywhere from three to five years for a business in terms of that payback period for solar. So, you know, we're not just looking at a payback period, and then, all of a sudden, that revenue stream dries up. If we purchase a high-quality system, then that revenue stream is going to be locked in for a 25-year period, which is great for a business owner.

For commercial businesses, it may be even more important, again, because they're putting so many of these panels on a roof. So for a residential customer, they might only be putting 20 panels on a roof, but for a commercial site, there could be three to 400. So if you've got a fault or you're choosing a cheap panel, the exercise to go and remove all those panels and install new ones, it's vastly greater than it is at a domestic level. So quality's even more important on commercial sites, for me, than it is on residential sites, because it's such a big investment for a business. That said, the investment itself is something that's really worthwhile doing. The savings for businesses can typically be much better, because most of that power that a solar system generates on a business is being used during the daytime, and that's when everyone's at work, so the paybacks can be exceptional for businesses, and I've seen them, even below three years, as low as two and a half years, which is great.
