Modules have no moving parts and a 25-year performance warranty, but dust, bird droppings, loose fasteners, clogged inverter filters and neglected earthing quietly steal generation. Businesses that treat maintenance as an afterthought see the bill savings they modelled in year one disappear by year three. A commercial rooftop plant is often marketed as a set-and-forget asset.

The inverter turns on. The first bill is more attractive. And then year-one generation is 15–30 percent below proposal, because a water tank shadows a string every winter afternoon, the roof was never checked for load, or the cheapest bid used thin structure and mixed cables. It’s installation and design flaws, not “solar doesn’t work.” A commercial solar plant fails in slow motion, more often than on day one. The inverter turns on. The first bill is more attractive.
