A solar ad that sounds like a government giveaway should be treated as a claim to verify, not as a fact. The Department of Energy warns consumers to be cautious about offers that say panels are free or that a government program requires companies to provide them. The Federal Trade Commission also warns that solar's popularity has created more room for misleading door-to-door, phone, and online pitches.
Real public programs can exist, especially income-qualified, community solar, state rebate, utility, municipal, or nonprofit programs. The problem is that those programs have eligibility rules, funding limits, application periods, ownership details, and utility requirements. A private lead form should not be treated as proof that a public program is open for a specific address.
