The article highlights a Bowling Green State University project focused on creating tougher solar panel glass designed to endure the harsh Midwest climate, including dreaded golf-ball-sized hail. The goal is to reduce damage, costs, and downtime for solar energy systems.
It also showcases how university-industry collaboration and hands-on training are driving innovations that could reshape the solar panel supply chain.
Project scope and partnerships
Funded by an $850,000 grant from the Northwest Ohio Innovation Consortium, the initiative links BGSU with the University of Toledo and First Solar. The Northwest Ohio Glass Innovation Hub has served as the collaboration platform since 2024.
The effort is led by Joseph Furgal, Ph.D., at BGSU’s Center for Photochemical Sciences. He works in concert with industry partners to push the boundaries of glass science for solar modules.
Funding and collaboration network
The grant supports a multi-institutional team that leverages raw glass and panel samples from First Solar and combines academic research with real-world testing. The collaboration extends to the University of Toledo, enabling a broader set of facilities, talent, and perspectives.
This network is designed to bridge the gap between fundamental glass science and scalable, cost-effective manufacturing.
Four-pronged approach to tougher glass
To safeguard solar panels against edge-related cracking and other durability challenges, the team is pursuing four complementary strategies. These approaches target the most vulnerable areas and aim to deliver panels that are thinner, lighter, and less expensive without sacrificing performance.
Inorganic treatments to heal microscopic cracks
One line of research focuses on inorganic surface treatments that can seal and repair tiny cracks that form in glass during operation or fabrication. By reinforcing the glass at the micro level, this method aims to impede crack initiation and slow propagation.
Hybrid organic coatings to cushion impacts
Another track combines hybrid organic coatings with the glass substrate to absorb and dissipate energy from impacts. These coatings are designed to work with the glass’s chemistry to reduce fracture risk at the edges where stress concentrates after hail or wind events.
Laser edge-delete modifications to remove weak points
Researchers are testing laser edge-delete techniques that precisely remove vulnerable edge points and microcracks, effectively hardening the panel’s perimeter. By eliminating known weak spots, this approach can reduce the probability of crack initiation and slow subsequent crack growth.
High-speed screening to study crack behavior
A fourth pillar uses high-speed screening and modeling to observe how cracks behave under real-world loading and environmental conditions. This data-driven approach informs design tweaks and process controls.
Impact on performance, costs, and resilience
The overarching goal is to deliver solar modules that are thinner, lighter and lower in cost while delivering equivalent or superior durability and energy output. Strengthening glass and edge integrity can reduce manufacturing and replacement expenses, lower insurance claims, and improve overall energy production in challenging climates.
Potential industry-wide benefits
- Reduced material and production costs due to stronger glass and lighter modules
- Longer service life for solar installations in hail-prone and extreme-weather regions
- Lower maintenance and insurance costs for solar fleets
- New pathways for industry-academia collaboration and workforce development
Education, training, and workforce development
The project serves as a hands-on training ground for undergraduates, graduates, and postdocs, who work directly with industry partners to solve real-world problems. Students gain valuable laboratory experience, professional networking, and potential pathways to internships and jobs with partner organizations.
Timeline and path to commercialization
Initial results are expected in late spring or early summer 2026.
The findings may inform future commercial standards for solar-panel manufacturing.
The consortium expects to translate laboratory breakthroughs into practical manufacturing guidelines.
This could lead to new product offerings that improve resilience and cost competitiveness of solar energy systems in the Midwest and beyond.
