A 60-cell photovoltaic module typically measures about 65 inches by 39 inches (or roughly 5.4 feet by 3.25 feet), while a 72-cell unit is larger, averaging around 77 inches by 39 inches (approximately 6.4 feet by 3.25 feet).
[pdf] The TOPBiHiKu7 panels feature 210 mm cells and are available in six versions, with nominal power ranging from 675 W to 700 W, and a power conversion efficiency of 21.7% to 22.5%. The open-circuit voltage ranges from 46.9 V to 47.9 V and the short-circuit current is 18.24 A to 18.49 A.
[pdf] But here’s the kicker: Colombian material’s lower ash content (<0.5% vs. China’s 2-8%) makes it perfect for energy storage applications. While current prices average $2,100-$2,500/ton (FOB Cartagena) vs. China’s $1,800, quality-focused buyers are willing to pay the premium.
