Will Solar Panel Installation Quadruple by 2030?

Dr. Gilbert Michaud is a professor at the Voinovich School of Leadership and Public Affairs at Ohio University. He studies renewable energy policy and economic development, and he shared his insights about the potential exponential growth of solar installations.

“I do, in fact, believe that the prediction that the U.S. solar industry will quadruple its installations by 2030 is accurate.

Currently, we have about 100 gigawatts of installed solar capacity in the United States. And, if we actually look at this solar installation curve over time, say, over the past 20, 30 years or so, we’re starting to see a much steeper upward slope of this curve as more solar continues to come online.

And there are a variety of drivers for this development. First, solar installation costs continue to decline dramatically as photovoltaic modules and other materials become more efficient and cheaper in price. Second, state and local governments continue to adopt more aggressive solar energy incentives as the technology becomes more familiar many states are setting things like decarbonization goals. And then, third, we’re also seeing a huge increase in corporate demand for renewable energy, such as solar energy, which is really driving project development at an accelerated rate.

A lot of businesses have things like corporate sustainability missions, and they want to have onsite solar or, at the very least, purchase the output of solar projects that are near to them.

We’re starting to see many more large, utility-scale solar projects, as well — solar farms, if you will, that are being built across the U.S., which also achieve even lower costs through economies of scale.

And these really big installations are also going to accelerate the pace of solar being constructed across the country.

So, businesses, homeowners, electric utilities, state and local governments and a lot of other folks are really seeking solar energy as a means to their electricity.

I think, coupled with incentives such as the federal investment tax credit for solar that we have in the U.S. and a lot of these prior-mentioned drivers, that solar will only continue to increase, especially given the new federal administration’s focus on things like energy and climate solutions.”

Physical Retail’s Next Infrastructure Layer: Item-Level Intelligence with Radar
June 4, 2026

Physical retail is under pressure to become as measurable and responsive as e-commerce. While retailers have spent years optimizing digital channels with real-time data, store teams have often had to make decisions with incomplete inventory visibility and delayed operational signals. That gap matters because stores still account for 80% of U.S. retail sales, making…

From Institutional Excellence to Population-Level Access: How Pakistan Can Bridge Its Healthcare Divide
June 1, 2026

Healthcare systems are under pressure almost everywhere, but the strain is especially visible in lower-resource settings where demand is rising faster than infrastructure. In Pakistan, that pressure is playing out across a system that has to serve more than 250 million people with limited public investment. Public health spending remains below 1% of GDP,…

Scaling Experiential Learning in the Curriculum: How Iron Range Engineering Transformed Engineering Education
June 1, 2026

Engineering has transformed nearly every part of modern life, from the phones in our pockets to the systems powering global industry. But the way engineers are educated has often moved far more slowly than the profession itself. Employers are asking for graduates who can navigate ambiguity, communicate across teams, and contribute meaningfully from the…

When Geography Meets Purpose: How One Move Reshaped a Vascular Surgeon’s Career
May 28, 2026

Medicine isn’t what it used to be—not for the people practicing it. Independent physicians are becoming the exception, not the norm, as more doctors move into hospital systems, corporate groups, and academic networks. At the same time, the pipeline of specialists isn’t keeping pace with growing patient needs, particularly in complex fields like vascular…
