Yes, solar lights are highly cost-effective in the long run. While the initial investment may be higher than traditional lighting, the ongoing savings on electricity bills, low maintenance, and long lifespan make them a smart financial choice.

The ITC is a tax credit that offers 30% back on the cost of switching to solar-powered products. For example, if you spend $50,000 on solar lighting, you can receive a $15,000 credit back from the federal government in the first year. This makes solar lighting projects more affordable upfront.
