Is commercial solar worth it for my business?

For most businesses with daytime electricity use and roof or ground space, commercial solar is one of the strongest-return investments available — typical paybacks are around 4–6 years, after which you generate largely free electricity for another 20+ years. Because businesses use most of their power during daylight hours (exactly when panels generate), self-consumption is high, which is what drives the return. Add in capital allowances and protection from rising energy prices, and the case is often compelling.
