As the House Republicans’ proposal to end federal tax credits for solar energy looms, homeowners are faced with a critical deadline: claim their solar energy investment before it’s too late. With the future of renewable energy in the US hanging in the balance, experts warn that policy uncertainty could freeze investment and raise costs.
Solar Tax Credit: A Critical Deadline Looms
The Future of Renewable Energy in the US
For homeowners in the US who can afford it, installing solar panels is a crucial decision that can significantly reduce their energy bills. However, with the House Republicans’ proposal to end federal tax credits for solar energy, many are left wondering if now is the right time to invest in renewable energy.
Solar energy is a clean and sustainable source of power that uses sunlight to generate electricity.
Photovoltaic (PV) cells convert sunlight into electrical current, while solar thermal systems use sunlight to heat water or air for use in buildings.
According to the International Energy Agency (IEA), solar energy accounted for 3% of global electricity generation in 2020.
The cost of solar panels has decreased by over 70% in the last decade, making it a more viable option for households and businesses.
The Solar Tax Credit: A Lifeline for Homeowners
The solar tax credit has been a vital incentive for homeowners to adopt solar energy since its introduction in 1978. Initially allowed to lapse in 1985, it was revived in 2005 by President George W. Bush. Over the years, lawmakers have extended and tweaked the incentives, most recently with the 2022 Inflation Reduction Act (IRA), which set the credit at 30% of the cost of a system until 2032.
The solar tax credit, also known as the Investment Tax Credit (ITC), is a federal incentive for individuals and businesses to install solar panels on their properties.
It allows homeowners and companies to deduct a percentage of the total cost from their taxes, reducing their taxable income.
The credit was introduced in 2006 and has undergone several changes since then.
As of 2022, the ITC remains at 26% of the total system cost for residential installations and 22% for commercial projects.
The Impact on Solar Installation
The average cost of a solar system in the US is around $28,000, making the tax credit worth approximately $8,500. Without this incentive, solar systems might still make financial sense in places with high sunlight or electricity prices, but the payback period will likely increase for many homeowners.

A Threat to the Solar Industry
The House Ways and Means Committee’s proposal to roll back large swaths of the IRA, including support for residential solar, has sent shockwaves through the industry. The 25D tax credit would still apply to systems installed this year, but it would be eliminated completely after that. This move could lead to a surge in installations this year followed by a market contraction.
The Inflation Reduction Act (IRA) is a comprehensive legislation aimed at reducing inflation, promoting economic growth, and addressing climate change.
Signed into law in August 2022, it provides $369 billion for energy and climate initiatives, including tax credits for clean energy technologies.
The IRA also introduces a minimum corporate tax rate of 15% and imposes penalties on companies that shift profits to low-tax jurisdictions.
Additionally, the act allocates funds for healthcare, education, and social programs, with an emphasis on reducing the national debt.
A Shift to Third-Party Ownership
Instead of eliminating the 48E credit, which allows businesses to reduce what they charge customers when installing solar panels on homes, the House favors applying limits on where the material in photovoltaic panels comes from. This could make the credit effectively impossible to access starting in 2026.
Consequences for the Solar Industry and Economy
Experts warn that this move will have devastating consequences for companies, their employees, and customers. The solar industry supports hundreds of thousands of workers and tens of billions of dollars in investment every year. Policy volatility is also a major concern, as it can freeze investment, raise costs, and damage market confidence.
A Call to Action
While the future of the solar tax credit is uncertain, many experts believe that this proposal will not become law in its current form. The Senate has the power to rectify any rollbacks and make necessary adjustments to ensure the continued support for renewable energy. As Jacquelyn Pless, a professor who researches energy and environmental economics at MIT Sloan School of Management, notes, ‘Policy uncertainty alone can start to freeze investment, raise costs, and damage market confidence.’
