1. Which photovoltaic panel technology is capable of producing electricity from both of its active sides?
The monocrystalline panel The polycrystalline panel The bifacial panel The thin-film panel
2. What is the main economic advantage of polycrystalline panels compared to monocrystalline panels?
Higher yield A generally lower manufacturing cost Improved resistance to high temperatures A longer lifespan
3. Why do monocrystalline panels generally offer better performance?
Because their cells are made of a single silicon crystal, which promotes the flow of electrons. Because they use two active faces Because they are made from thin layers Because they only work on alternating current
4. Of the following technologies, which is recognized as one of the most efficient among thin film panels?
a-Si (Amorphous Silicon) CdTe (Cadmium telluride) Polycrystalline CIGS (Copper-Indium-Gallium-Selenium)
5. What is the main disadvantage of polycrystalline panels compared to monocrystalline panels?
A shorter lifespan Lower yields require a larger area An impossibility of being used in large power plants Lack of manufacturer's warranty
6. What criterion directly influences the performance of a bifacial solar panel?
The frequency of the electrical grid The color of the aluminum frame The albedo of the surface located under the panel The type of battery used
7. What is the main objective of the development of new photovoltaic cell technologies (PERC, TOPCon, HJT, IBC)?
Increase efficiency and reduce energy losses Reduce only the weight of the panels Eliminate the use of silicon Replace the photovoltaic inverters
8. What type of panel is particularly recommended for Building Integrated Photovoltaics (BIPV), facades and certain flexible applications?
The bifacial panel The polycrystalline panel The monocrystalline panel Thin Film Panel
9. Which panel is currently considered the dominant technology for residential and commercial installations due to its excellent performance?
The monocrystalline panel The polycrystalline panel The amorphous silicon panel The CdTe panel
10. What factor primarily limits the energy gain of a bifacial panel when installed directly against a roof, with no space behind it?
Low purity of silicon Insufficient output voltage Absence of tempered glass The inability of the rear surface to capture reflected light
