What is the average profit margin for solar panel installers? Residential and commercial solar installers typically see gross margins of 20–40% and net margins of 10–25%, depending on system size and efficiency of operations. Do solar panel manufacturers make a lot of money? Not.
With solar panel costs dropping by approximately 50% since 2010 and the federal tax credit currently at 30% (though under threat of elimination by December 2025), homeowners are increasingly asking: is solar a good investment? The short answer is yes, for most homeowners.
