5A sustainable energy entrepreneur is designing a solar grid that uses panels arranged in rectangular arrays. Each array must contain exactly 192 panels, arranged in a number of rows and columns where the number of columns is at least 2 more than the number of rows. What is the maximum possible number of rows such that the configuration satisfies the startups design constraints?

["The Rise of Precision Solar Grid Design in Clean Energy Innovation \nAs renewable energy adoption accelerates in the U.S., innovative solar grid design is gaining traction among clean tech entrepreneurs. One emerging approach focuses on structuring solar panel arrays with mathematical precision—ensuring efficient space use, cost control, and scalable output. At the heart of this trend is a technical constraint rooted in real-world deployment: panels must fit into rectangular arrays where the number of columns exceeds the number of rows by at least two. This balance supports not only engineering needs but also scalability and integration into existing infrastructure. Understanding this constraint reveals deeper insights into modern solar design strategies shaping the industry.", "Why 5A Sustainable Energy Entrepreneur Is Rethinking Solar Arrays \nThe 5A sustainable energy entrepreneur is pioneering a novel photovoltaic layout where each array contains exactly 192 solar panels. This design demands strict adherence to a mathematical relationship: columns must be at least two more than rows. Why does this matter? Such configurations optimize land use, reduce wiring complexity, and enable modular expansion—key considerations for both rooftop installations and utility-scale projects. As clean energy markets mature, entrepreneurs are increasingly leveraging geometry and efficiency to deliver higher returns with fewer resources. This approach aligns with broader trends toward smart, compact, and economically viable renewable solutions.", "How the Grid Works: Mathematics Behind the Design \nLet the number of rows be \( r \) and columns be \( c \), with \( c \geq r + 2 \), and \( r \ imes c = 192 \). To find the maximum possible \( r \), start by factoring 192 to identify valid row-column pairings. The complete factor pairs of 192 include: \n- \( (1, 192) \) \n- \( (2, 96) \) \n- \( (3, 64) \) \n- \( (4, 48) \) \n- \( (6, 32) \) \n- \( (8, 24) \) \n- \( (12, 16) \) \n- \( (16, 12) \) \n- \( (24, 8) \) \n- \( (32, 6) \) \n- \( (48, 4) \) \n- \( (64, 3) \) \n- \( (96, 2)"]
