Photovoltaic solar energy units take in solar energy and convert it to electricity by absorbing energy through simulated solar radiation. In this case, it is done through a panel of powerful solar lamps. These systems are part of a new set of technology that doesn’t harm the environment and is considered a more “green” alternative. Using photovoltaic solar energy units, students will gain a strong handle on converting solar energy into electricity in a safe and accessible way.

The unit has been designed to give students a good understanding of solar energy technology. This unit demonstrates a Photovoltaic Solar Energy Unit generating electrical power from simulated solar radiation.

The EESFC unit is a computer-controlled unit with a diagram on the front panel. It has two polycrystalline photovoltaic solar panels with tempered glass modules that have a high level of transmissivity, modified ethylene-vinyl acetate encapsulating material, and an output nominal power of 66W. There is also a solar simulator with an aluminum frame and eight 400W halogen lamps.

Solar radiation sensors make it possible to study the way the solar photovoltaic panels act by measuring the temperatures in both panels as well as the environmental temperature. A computer system measures the voltage and current either before or after the regulation of the lamp intensity. Students will be protected from any direct visual contact with the halogen lights and will have limited direct contact with the photovoltaic solar panels due to four protective blinds on the unit.

A DC loads module is included in the unit as well with two 24V lamps, a 5W DC battery with a voltage of 36V, and a 500W rheostat. There are four connection options included: The solar panels are connected directly to the charge regulator without the DC module, the DC motor and solar panels are directly connected, the solar panels are connected directly to the rheostat and lamps, or the solar panels are used in an open circuit fashion. Calibration exercises are included with the unit so students can learn how to calibrate a sensor and understand the importance of accuracy when adhering to these vital pieces.

The unit is supplied with the suitable sensors and instrumentation for the most representative parameters measurements and controls (electronic console).
