Features of Photovoltaic Solar Modules

Photovoltaic solar modules are designed to convert sunlight into electrical current, making them essential for renewable energy systems. The modules' inclination can be adjusted for optimal performance, and they can be connected in series or parallel using cables. A slide resistor simulates varying loads, allowing for the recording of current-voltage characteristics. A measuring amplifier displays all relevant variables, and two power resistors expand the measuring range for low illuminance conditions. Integrated sensors detect illuminance and temperature levels. For best operation, the system should be used under sunlight or an optional artificial light source.

Key Features:

• Pivoting solar modules on mobile frames for easy adjustment.

• Series and parallel connection options for flexibility.

• Slide resistor as a variable load for dynamic testing.

• Two power resistors to expand the measuring range under low illuminance.

• Measuring amplifier with digital displays for current, voltage, illuminance, and module temperature.

• Reference cell used as an illuminance sensor.

Installation and Commissioning

The installation and commissioning of the system must be completed within 1 month from the delivery date at no additional cost to the polytechnic. All installation and commissioning work should be finished prior to the training session at the site.

Training at Site

• Duration: Minimum of 2 days

• Participants: Minimum of 5 nominated individuals from the institution

• Objective: Trainees should be able to operate and conduct experiments with the equipment upon completion of training. The training should be separate from the installation and commissioning process.

After-Sales Service

• Warranty: Minimum of 3 years, including parts and labor, from the date of successful installation, commissioning, and handover.
