“Perhaps the biggest challenge for nonprofits that want to install solar energy systems is that a variety of tax laws have created a perverse disincentive where donations to buy solar panels actually hurt the nonprofit. Since renewable energy projects are incentivized through the tax code, every dollar donated to a tax-exempt organization in support of a solar project immediately suffers a tax consequence that cuts the value of the donation nearly in half.”
