NREL’s improvement in performance characterization has significantly reduced the margin of error, which helps the solar industry set accurate module prices and expectations for output. Solar panel efficiency is calculated with a set of Standard Test Conditions (STC), which are used by the entire solar industry. As you might already know, the cells are the core of a solar panel. “From our point of view, both records are of great importance because photovoltaic devices can be classified in those different area categories and are done so in the world rankings,” research co-author Andreas Distler told pv magazine. Maximum Power - this is the maximum power out put of the PV module (see I-V curve below) 2. In our example for the SW 245 mono (245/1.676.67)=14.61% efficiency Remember to look at the power tolerance as although the name plate rating might be 245W, the power tolerance will tell you how many more or less Watts a the STC the panel produce. 29.15% efficiency is not only the record for this technology but is at the very top of the entire Emerging PV category in the NREL [National Renewable Energy Laboratory] chart. “With improved equipment, I am sure the 12.6% PCE [power conversion efficiency] could also be reached on the bigger module area,” he said. Solar panels are an investment that can provide solid, steady returns for your home or business for years to come, while helping the environment and demonstrating your commitment to ethical practices and energy efficiency. Stay informed. Slower, nanosecond-pulse laser patterning was used – rather than femtosecond pulses – to avoid laser ablation of active layer material in the active area.
