Stated purpose

According to the site, Wattcrunch was built as an alternative to solar calculators that function primarily as lead-generation tools for installers and that, in its assessment, overstate potential savings. As an example, it points to the expiration of the 30% federal residential solar tax credit (Section 25D) on December 31, 2025, which it says many other online calculators continued to apply after the fact
