A study of 500,000 homes found savings of about $700 a year, when all the costs and benefits were included.

Alternatives employee Tony Chang installs no-cost solar panels on the rooftop of a low-income household on October 19, 2023 in Pomona, California. GRID Alternatives has installed no-cost solar for over 29,000 low-income households located in underserved communities.

Much previous research has focused only on direct utility bill savings of solar power, which can be misleading. For instance, if the cost of installation is excluded, the median household would erroneously calculate $1,987, not $691, in savings. In 2018, KB Homes Bridgepoint at Patterson Ranch development in Fremont had solar included with the purchase of the new homes.

Low-income residents in the U.S. West who have installed solar power experience the greatest benefit with the proportion of estimated household income spent on energy falling from 7.3% to as much as 5.7%, saving an estimated $821 a year. GRID Alternatives employees Tony Chang and Sal Miranda install no-cost solar panels on the rooftop of a low-income household on October 19, 2023 in Pomona, California. GRID Alternatives has installed no-cost solar for over 29,000 low-income households located in underserved communities which are most impacted by pollution, underemployment and climate change.
