Solpro FAQ - What are the performance data of a PV module?

What performance data does a PV module have?

Answer from the Solpro expert꞉

The performance data of a PV module is crucial for evaluating its efficiency and general performance. The most important performance data include

    1. Nominal power (Watt Peak, Wp):
      This is the maximum power that the module can achieve under standardized test conditions, for example with solar irradiation of 1000 W/m² and a cell temperature of 25°C. The rated power indicates how much energy the module can produce under ideal conditions.

    2. Efficiency:
      The efficiency of a module is the ratio of the generated electrical power to the irradiated solar power. A higher efficiency means that the module converts the solar energy into electrical energy more efficiently, which is crucial for optimum energy yield.

    3. Voltage and current:
      This information provides details of the electrical voltage (volts) and current (amperes) that the module supplies under certain operating conditions.

    4. Temperature coefficients:
      These values show how the performance of the module changes with increasing temperature. They are important for understanding the power adjustment of the module under different environmental conditions.

This performance data is critical to understanding and evaluating the quality and efficiency of Solpro PV modules. At Solpro, we take great care to ensure that our modules meet or exceed these criteria in order to provide our customers with the best possible energy efficiency and reliability. Careful selection and evaluation of this data enables our customers to make an informed decision on the best solar solution for their specific needs.
