The BlueSun solar panel of the BSM300P-60/5BB series, model BSM290P-60, offers a nominal power of 290 watts at standard test conditions in STC (Standard Test Conditions). Its open circuit voltage (Voc) reaches 39.63 V, while its maximum voltage (Vmp) is 32.56 V. The short circuit current (Isc) is measured at 9.56 A, with a maximum current (Imp) of 8.91 A .

The efficiency of this solar panel is 17.86%, which indicates its energy efficiency. It is important to note that the power tolerance is between -0 and +5 watts, meaning the panel may slightly exceed its power rating.

Regarding performance variations depending on temperature, the temperature coefficient of Isc (Isc Temperature Coefficient) is +0.058%/°C, the temperature coefficient of Voc (Voc Temperature Coefficient) is -0.330% /°C, and the temperature coefficient of Pmax (Pmax Temperature Coefficient) is -0.410%/°C. These coefficients indicate how the performance of the solar panel varies depending on the ambient temperature.

In summary, the BlueSun BSM290P-60 solar panel is a 290 watt model with suitable voltage and current specifications for solar power generation. It displays respectable efficiency and moderate power tolerance, while being designed to minimize the effects of temperature variations.
