  • Millennial homeowners are nearly six times more likely to own solar panels than baby boomer homeowners
  • Millennial homeowners also anticipate paying off a solar loan of $20K three times faster than baby boomer homeowners
  • High-income homeowners have a better understanding of solar incentives and the cost of solar compared to lower-income homeowners

On March 15 and 16, 2022, SaveOnEnergy.com® commissioned a YouGov survey of 655 American adult homeowners to gauge their understanding of solar panel costs and incentive programs. 

Nearly half (45%) of the homeowners overestimate or have no idea about the average cost of solar panels for a single-family home. According to the Center for Sustainable Energy, the average cost for a residential solar system ranges from $15,000 to $25,000 before any incentives. Only a fifth (20%) of homeowners were able to correctly estimate the cost before incentives, while 43% underestimate that the average cost of solar was less than $15,000, 12% overestimate the cost to be $30,000 or more and 24% are clueless about the pre-incentive costs.

Additionally, a little over a fifth (22%) of homeowners correctly estimate the average cost of solar for a single family home after incentives to be roughly between $10,000-$24,999. While 36% underestimate that the average cost to be less than $10,000, 9% overestimate the cost to be $25,000 or more, and roughly a third (32%) of American homeowners said they have no idea how much solar panels cost post-incentives.

There is also a generational information gap about incentives and the cost of solar. Baby Boomer homeowners (ages 57-75) are twice as likely to say they have no idea about the average cost of solar panels before incentives than Millennial homeowners (ages 25-40) (30% vs. 15%). Nearly one-fourth (23%) of Gen X homeowners (ages 41-56) say they are clueless about pre-incentive costs. There is a smaller gap when it comes to perceptions of average solar costs after incentives.

Homeowners Who Have No Idea About Solar Costs – Generational Differences

Before Incentives After Incentives
Baby Boomers (ages 57-75) 30% 38%
Generation X (ages 41-56) 23% 32%
Millennials (ages 25-40) 15% 23%

Over One in Four (26%) American homeowners are unaware of any solar incentives

Solar incentives: including the Federal Tax Incentive, also known as the Solar ITC, as well as state and/or local incentives like rebates, net metering, and low-interest rates. (This definition was provided to survey participants.)

Over half (57%) of American homeowners have heard of solar incentives, but they do not know much about them. 17% of homeowners said they have heard of solar incentives and they have a good understanding of them. Of the 17%, more than a third (36%) also said that they did not know how these incentives affect the final cost of solar panels.

The knowledge gap around solar costs and ways to reduce them with consumer incentive programs may be a big barrier to solar adoption among many homeowners in the U.S. 

Not taking advantage of government incentive programs would be similar to throwing money away. Federal and state solar tax credits can significantly lower the cost of solar for homeowners. Enacted in 2006, the federal Investment Tax Credit (ITC) has been a critical policy to incentivize the deployment of solar panels in the U.S. Currently set at 26%, the ITC provides a dollar-for-dollar reduction of a solar owner’s income tax. The ITC is applicable to both residential and commercial solar projects. In addition, many states provide solar incentives, such as net metering, property tax exemptions, sales tax exemptions, solar renewable energy certificates, and state tax credits.

Millennials are more likely to own solar panels than older generations

Among the survey participants, Millennial homeowners are nearly six times more likely to own solar panels (29%) than Baby Boomers (5%) and nearly three times as likely to own them as Gen X homeowners (10%). 95% of Baby Boomers and 90% of Gen X currently do not own solar panels compared to 71% of Millennials. According to the survey findings, there were no major differences between income levels when it comes to owning solar panels. 

The generational difference in owning solar panels reflects the overall trend of younger Americans recognizing the threat of climate change to their future. The 2021 research from Pew Research showed that Millennials were open to more ambitious climate policies and were more involved in climate activism than older generations. In terms of the adoption of solar panels, Millennials seem to put their money where their mouth is.

Millennials anticipate paying off solar loans sooner than Boomers and Gen X

According to the survey, half of Millennial homeowners (50%) are more likely to anticipate paying off a solar loan of $20,000 within 3-5 years compared to Gen Xers (33%) and Baby Boomers (31%). Roughly 29% of Boomers responded that they were likely to pay off such a loan within 10-15 years. 17% of Millennials reported that it would take them 10-15 years to pay off the $20,000 solar loan.

The survey also found that participants’ educational and income levels correlated closely with their knowledge about the cost of solar and incentive programs. 11% of homeowners earning under $40K said they had a good understanding of solar incentives. By contrast, twice as many homeowners earning $80K+ (21%) felt they had a good grasp of incentive programs. Americans without a high school diploma/only high school diploma were less likely to know about solar incentives than those with higher education, with 10% saying they had a good understanding of solar incentives (vs. 20% or more of those with at least some college). 

Overall, the survey suggests that the knowledge gap among Americans regarding solar costs and incentive programs is one of the key factors to help us understand certain consumer perceptions about solar energy. As solar panels become more accessible to the average homeowner, bridging the knowledge gap about the benefits and affordability of solar could help more Americans embrace it.
